Plant Taxonomy: Plant taxonomy classifies aloe vera plant as Aloe barbadensis. [图片]Plant Type: A. barbadensis grows as perennial in tropical and sub-tropical regions, where the leaves of these clump-forming succulents are evergreen. Typically found in the wild in hot, dry climates, they're a natural for desert landscaping. Characteristics: While capable of achieving a height of 3 feet, aloe vera plants more typically mature to be 1 or 2 feet tall. If you grow these tropical plants indoors in containers, they most likely will remain on the shorter end of the height spectrum. When grown outdoors in warm climates, mature plants will produce yellow or orange flower heads on tall stalks. The sword-shaped, often grayish-green leaves grow in rosettes and are sometimes studded with white flecks. Short teeth run up the edges of the leaves. Planting Zones for Aloe Vera Plants: Grow these succulents in planting zones 9, 10 or 11. They are thought to be indigenous to Africa. Sun and Soil Requirements: Grow in full sun to partial shade and in a well-drained soil. These succulents are drought-resistant plants once established. Care for Aloe Vera Plants: The key to growing these cactus-like plants is providing good drainage. When using aloe vera as a landscape plant, incorporate sand into the soil. For potting, be sure to place crushed stone at the bottom of the container, which should, of course, have a drainage hole in its bottom. Aloe vera plant is relatively dormant in winter, meaning it will need very little water at that time. Even during the summer, be careful not to over-water established specimens. If the leaves show signs of browning, consider cutting back on sun exposure. As a houseplant, provide bright light. Medicinal Uses for Aloe Vera Plants: Famous for its soothing medicinal properties, potted A. barbadensis is kept as a houseplant by many people who treat it as "living first aid." E.g., when they burn a finger, they'll break off a lower leaf and rub the juice on the burn. Removing the leaf does no damage to the plant. This medicinal wonder's motto is, "Doctor, heal thyself": the wound where the leaf was removed heals quickly. [图片]Where to Use Aloe Vera Plants: As a potted plant, it may be treated as a houseplant to be used in interiorscaping or installed on patios, decks, etc. In the landscape (in zones 9, 10 and 11), its need for good drainage makes it an excellent candidate for rock gardens. These drought-tolerant succulents are also a natural for xeriscape design. Propagation is easy: just break off the offsets, allow them to make contact with the ground (sand is a preferred rooting medium) and watch them root! Meaning of the Name: There are many types of aloes in the world. Aloe vera plant is just one type, although it is, to be sure, the best known of the aloes. Perhaps that's why Linnaeus referred to this aloe as vera (Latin for "true"). The term stuck as part of the common name, but for the scientific name, many now prefer the designation of Philip Miller, a Scottish botanist: Aloe barbadensis. Miller's specific epithet, barbadensis means "of Barbados." That's a rather misleading name since most experts do not believe the plants to be native to Barbados (asserting, instead, that they were brought there by the Spaniards). As for the genus name, Aloe, the Online Etymology Dictionary states that the word derives from the Greek, aloe, a translation of the Hebrew name, ahalim. The plant is, indeed, mentioned in the Bible.

[图片]06Sedum Spurium Picture With a common name like "Dragon's Blood," one expects a lot of color out of this sedum.... But how much color you get depends on the amount of sunshine you give it, among other factors. The Sedum spurium 'Dragon's Blood' in the picture has reddish stems and pink flowers. Some types of Sedum spurium have red flowers and/or red leaves, as well. Being a succulent, there is a fleshy feel to this plant that some gardeners may find appealing (if you're the type that likes to touch your plants frequently, as I do). Furthermore, as with most succulents, Sedum spurium is drought-tolerant. [图片]07Pictures of Cacti and Succulents: Ice Plant This ice plant is one of the hardy succulents and can be left outside in winter all the way to planting zone 5. However, that's not how it received its name.... Rather, its the "icy" look of its foliage that earns it its name. An optical illusion is caused by the way light bounces off the tiny hairs on the surface of the ice plant's leaves, mimicking the appearance of ice crystals. There are a number of different types of ice plant. The ice plant in this picture is a type known as Delosperma cooperi. If I had to choose between the succulents I've covered so far in terms of recommending the one that best combines beautiful flowers with attractive foliage, my selection would be ice plant. [图片]08Yucca Plant Picture Photo of a yucca plant.... A dwarf plant, the sword-shaped leaves of the Yucca nana shown in the picture bear the threads (or "filaments") that give another type of yucca its scientific plant name: Yucca filamentosa, commonly known as "Adam's needle." [图片]09Picture of a Joshua Tree My picture of a Joshua tree above shows what Yucca brevifolia looks like. But you may wonder about the origin of the common name.... There's even a park in California named "Joshua Tree National Park." It is located in the Mojave Desert. So where does the name "Joshua" come from for this tree? Andrew Alden explains that it was the Mormon pioneers who were responsible for naming the Joshua tree. The reference is to the Book of Joshua in the Old Testament (8:18–29). The passage states that a Hebrew army, wielding javelins (on an order from God to "stretch out the javelin that is in your hand"), took the city of Ai and "raised over it a great heap of stones." Andrew asserts that "the name 'Joshua tree' surely derives from the stony landscape of the Mojave as well as the trees' outstretched arms and javelin-tip leaves." [图片]10Agave Picture The plant in this picture is an agave, which also belong to a family of plants called "Agave".... Confused? To clear up any confusion, simply look to see whether the name is capitalized or not. With a capital "A," I'm referring to a plant family. With a lower-case "a," I'm referring to a subset of that family. What other plants are in the Agave family, besides the agave? Well, one example is another plant I've been discussing in this photo gallery, namely, the yucca. Remember, while plants in the Agave family may resemble cactus, they are, in fact, distinct from their more famous desert cousins. Both groups of plants are, however, succulents. [图片]11Prickly Pear Cactus Fruit Picture Prickly pear cactus has yellow flowers. But that only begins to tell the tale of this fascinating plant.... Prickly pear cactus foliage reaches at most a little over one foot tall. But it's not just a foliage plant or a flowering plant, as it also bears an edible fruit (the red you see in my picture). If you enjoy edible landscaping, you may wish to experiment with growing this tough plant. Its scientific plant name is Opuntia compressa. It is one of the hardiest of the cacti. The photo above was taken in Arizona, but Opuntia is represented east of the Mississippi by Eastern prickly pear cactus. [图片]12Pictures of Cacti and Succulents: Cholla Cactus It's sometimes hard to think of cacti, such as the cholla cactus, as "succulents," even though that's how they're classified.... That's because we also use the word "succulent" colloquially to refer to delicious, juicy food. And even though some cacti have edible parts, our first impression when we see such spiny plants is, "There's no way that's coming anywhere near my mouth!" Nonetheless, the cholla cactus and other cacti do store water in their tissues -- the basic definition of a succulent plant. [图片]13Barrel Cactus Picture Some types of barrel cactus plants are popular as houseplants.... But for some of us, houseplants are the furthest thing from our minds when mention is made of "barrel cactus." If you watched Westerns as a kid, you probably recall seeing a thirsty cowboy slice off the top of a barrel cactus to get at the liquid stored inside. It's not just fiction: some species of Echinocactus barrel cacti do contain a reasonably palatable fluid (or so I am told) that is potable in an emergency. [图片]14Picture of Saguaro Cactus An imposing plant, the saguaro cactus is an enduring symbol of the American West. I snapped this photo of a saguaro cactus while surveying the Route 66 landscape.

[图片]01Portulaca Picture Plus Agave, Yucca Cacti and succulents come in a variety of shapes and sizes. Some of the tiny ones are best-suited to miniature garden arrangements, while giants such as the saguaro would be too big to be displayed suitably in some front yards! I use the terminology "cacti and succulents" here merely out of deference to popular convention. All cacti are, in fact, considered to be succulents (but not all succulents are cacti). View my pictures of cacti and succulents for some examples. I include photos of the succulents known as agave and yucca in this gallery. Although often thought of in connection with cacti, agave and yucca belong to a group of plants distinct from cacti. Succulents are known for their fleshy foliage. But other plants, as well, bear such "leathery" leaves, including: Montauk daisy Bitterroot Portulaca plants (also commonly called "moss rose") are annuals.... However, these succulents reseed readily. Portulacas are a good choice for areas with poor soils, and they can stand up to a pounding sun all day long. They are also popular in hanging baskets, their prostrate growth habit allowing them to cascade down the side of a container. The different colors they come in look wonderful mixed together. The edible weed named "purslane" is another type of portulaca. [图片]02Pictures of Cacti and Succulents: Hen and Chicks Mat-forming succulents, hen and chicks produces clusters of rosettes.... The parent rosettes are the "hens," and the smaller rosettes that spring from them are the "chicks." This low-growing (4") perennial will quickly spread to 2' or more in width. Although grown for its leaves, hen and chicks plant does flower, occasionally. [图片]03Autumn Joy Stonecrop Unlike the succulent in the prior picture, Autumn Joy stonecrop is very much grown for its flowers.... Sedum 'Autumn Joy wants full sun to partial shade and a well-drained soil. A popular plant for xeriscaping, Autumn Joy is a good candidate for rock gardens. [图片]04Frosty Morn Sedum Some sedums bear variegated leaves.... The name of this sedum cultivar, 'Frosty Morn,' refers to the white tinges on its otherwise green leaves. 'Frosty Morn' is grown primarily for its foliage. [图片]05Angelina Sedum Photo The gold flowers that emerge in spring on Angelina sedum can be a nice bonus added to the appeal of its chartreuse foliage, as long as you don't mind the rather gangly stems they bloom on.... But for me, it's the chartreuse foliage of these succulents that is the main draw for growing them. I like both its color and its feel. Angelina sedum will spread over time, so if you make it a point to avoid growing plants that fail to receive the highest marks for being well-behaved, you may not wish to grow it. Mass Angelina sedum plants together for use as a groundcover or short perennial border.

Description: This herbaceous plant is a biennial or short-lived perennial that becomes 4-8' tall. The stout central stem is unbranched or sparingly branched; it is light green, terete, and more or less hairy. The blades of the alternate leaves are up to 8" long and across; they are palmately lobed (with 3-7 blunt lobes each) and crenate along their margins. Each leaf blade is orbicular or oval in outline and indented at the base where the petiole joins the blade. The upper surface of each leaf blade is medium green, slightly pubescent to hairless, and wrinkled from fine veins; the lower surface is light green and pubescent. The petioles of the leaves are as long or a little longer than their blades; they are light green and hairy. The central stem terminates in a spike-like raceme of flowers; axillary flowers are produced from the axils of the upper leaves as well. These flowers occur individually or in small clusters along the central stem; they nod sideways from short hairy pedicels. Each flower spans about 3-5" when it is fully open; it has 5 petals, 5 sepals, 6-9 sepal-like bracts, and a columnar structure in the center with the reproductive organs (stamens toward the tip, thread-like stigmas below). The overlapping petals provide the flower with a funnelform shape; they are usually some shade of white, pink, or purplish red. The sepals are light green, ovate, and much smaller than the petals. The bracts of each flower are located underneath the sepals; they are light green, hairy, ovate, and joined together at the base. The blooming period occurs from mid-summer into the fall; a colony of plants will bloom for about 2 months. Each flower is replaced by a fruit containing a ring of 15-20 seeds (technically, a schizocarp). These seeds are oval, flattened, and notched on one side. The root system consists of a taproot. This plant spreads by reseeding itself.Central Stem & Flowerbud Cultivation: The preference is full to partial sun, moist to mesic conditions, and a fertile loamy soil. Lower leaves will wither away during hot dry weather. Hollyhock is vulnerable to foliar disease, including rust. [图片]Range & Habitat: The non-native Hollyhock occasionally escapes from cultivation, but it rarely persists. Escaped plants have been collected primarily in NE and east central Illinois (see Distribution Map). Habitats include areas along railroads, roadsides, vacant lots, and waste areas, especially in urban areas. Areas with a history of disturbance are preferred. Because of the showy flowers, Hollyhock is often cultivated in gardens. It is native to Eurasia. Faunal Associations: The flowers are cross-pollinated by several kinds of bees. Various insects feed on the leaves and other parts of Hollyhock. These include caterpillars of Pyrgus communis (Common Checkered Skipper), caterpillars of the butterflies Vanessa cardui (Painted Lady) and Strymon melinus (Gray Hairstreak), and caterpillars of such moths as Acontia aprica (Exposed Bird-Dropping Moth), Anomis erosa (Yellow Scallop Moth), Autographa precationis (Common Looper Moth), Mamestra configurata (Bertha Armyworm), and Astrotischeria omissa (Bouseman et al., 2006; Wagner, 2005; Covell, 1984/2005; Needham et al., 1928). Other insects that feed on Hollyhock include both adults and larvae of Apion longirostre (Hollyhock Weevil), adults of Popillia japonica (Japanese Beetle), Acyrthosiphon malvae (Geranium Aphid) and Aphis gossypii (Cotton Aphid), Brooksetta althaeae (Hollyhock Plant Bug), and larvae of the flies Calycomyza malvae and Melanagromyza hicksi (Cranshaw, 2004; personal observation; Blackman & Eastop, 2013; Pepper, 1965; Knight, 1941; Spencer & Steyskal, 1986). The foliage is palatable to cattle and other hoofed mammalian herbivores. Photographic Location: The photograph of the flower was taken at The Arboretum in Urbana, Illinois; the photographs of the stem and leaf were taken at a flower garden of the same city. [图片]Comments: The meaning of the common name is probably 'Holy Mallow.' Hollyhock is one of the taller members of the Mallow family. It superficially resembles one of the native Hibiscus spp. (Rose Mallows), which are perennial wetland plants. Hollyhock differs in having floral bracts that are ovate, while a Rose Mallow has floral bracts that are narrowly linear. The structures of their fruits also differ: the fruit of Hollyhock consists of a ring of seeds, while the fruit of Rose Mallow is a 5-celled capsule. Some of the taller Malva spp. (Mallows) also resemble Hollyhock, but they have only 1-3 bracts per flower; Hollyhock has 6-9 bracts per flower. An alternative scientific name for this species is Althaea rosea.

Description: This herbaceous perennial plant is 4-12" tall and unbranched, consisting of a rosette of leaves and a flowering stalk. The basal leaves are up to 3" long and 1" across. They are evergreen or semi-evergreen, obovate (spoon-shaped), and nearly hairless. Their margins are crenate and slightly undulate. The flowering stalk is 4-angled and slightly pubescent or hairy. The opposite leaves along this stalk are similar to the basal leaves, except that they are smaller in size and ovate. The flowers occur in a whorled spike along the upper half of the leafy stalk. They are produced in abundance and densely distributed along this spike. Each tubular flower is about 1/2–2/3" (12-17 mm.) in length, consisting of a 2-lipped corolla and a green calyx with 5 teeth. The corolla is usually various shades of blue-violet, and less often pink or white. There are dark blue-violet lines that lead toward the throat of the corolla; they function as nectar guides. The upper lip of the corolla is truncated and very small, while the large lower lip has 3 rounded lobes. The middle lobe of the lower lip is notched at its tip and the largest in size. The outer surface of the corolla behind the lobes is conspicuously hairy; this causes the flower buds to appear hairy. The blooming period occurs during the spring and lasts about 2-3 weeks. Each flower is replaced by 4 nutlets that are oval-shaped and pitted across the surface. The root system consists of a crown of fibrous roots. Green stolons up to 12" long are produced from the rosette of basal leaves. They are largely naked, except for a few small leaves that are narrowly ovate. These stolons often form new plantlets by rooting at their tips. Carpet Bugle can reproduce by seeds or vegetatively by means of these stolons; it often forms colonies. Cultivation: The preference is partial sun, slightly moist to mesic conditions, and a fertile loamy soil that is somewhat acidic. If the soil is poorly drained and soggy, crown rot can develop and spread rapidly. In sandy soil, the roots are occasionally attacked by nematodes. [图片]Range & Habitat: The non-native Carpet Bugle can escape from cultivation in gardens, but it is still uncommon in the wild, occurring in NE Illinois and Jackson County in southern Illinois (see Distribution Map). Habitats include partially shaded areas of lawns, edges of yards, partially shaded areas along foundations of buildings, nursery plots, and edges of woodlands. This plant is occasionally used as a ground cover because of its evergreen leaves and low spreading habit, but it is potentially invasive of natural areas. In Eurasia, where it is native, this plant occurs in partially shaded areas of deciduous woodlands, thickets, or meadows; the flowers bloom before the leaves of the trees have become fully developed. Faunal Associations: The flowers are pollinated by bumblebees and other long-tongued bees. According to sources within the horticulture industry, the foliage is rarely bothered by rabbits and deer. [图片]Photographic Location: The photographs were taken underneath a tree at Dave Monk's postage stamp prairie in Champaign, Illinois, and along the side of a house in NW Ohio. Comments: Different cultivars of Carpet Bugle are available through the horticultural industry that can vary considerably in the color of their flowers and foliage. The only other Ajuga sp. that has naturalized in Illinois is Ajuga genevensis (Geneva Bugle). This species is slightly taller with stems and leaves that are more hairy than Carpet Bugle; it also doesn't produce stolons. Carpet Bugle is easy to distinguish from other members of the Mint family because of the following combination of features: 1) Its blue-violet flowers are ½" in length or slightly larger, 2) the upper lip of the corolla is truncated and quite short, 3) the flowers occur in a terminal whorled spike, 4) the flowers bloom during the spring on stalks that are 1' tall or less, and 5) above ground stolons are produced in abundance from the rosette of basal leaves. This latter characteristic is especially useful in identifying this species because very few members of the Mint family produce above-ground stolons.

Description: This herbaceous perennial plant is 1-2½' tall, consisting of basal leaves and flowering stalks with alternate leaves. The stalks are light green and glabrous. The basal and lower leaves are bipinnate with 6-9 leaflets, while the upper leaves are pinnate with 3 leaflets. When the leaves are bipinnate, they are ternately divided into 3 groups of leaflets (2 lateral groups & a terminal group); each group has 2-3 leaflets. The leaflets of basal and lower leaves are 2-3" long and 1¼-2" across; they are medium to dark green, more or less ovate in shape, serrate or doubly serrate along their margins, and hairless or nearly so. Some leaflets may be deeply cleft into two lobes. The leaflets of upper leaves are smaller in size and more narrow in shape (lanceolate or oblong-lanceolate), otherwise they are similar to the leaflets of the preceding leaves. The petioles of basal and lower leaves are 4-12" long, while the petioles of upper leaves are less than 4" long. These petioles are light green and hairless; the petioles of alternate leaves are sheathed at their bases. The petiolule (basal stalklet) of the terminal group of leaflets is 2-3" long, while the petiolules of the lateral groups of leaflets are about 1" long. In each group of leaflets, the lateral leaflets are sessile or nearly so, while the terminal leaflet has a secondary basal stalklet that is nearly sessile to 1" long. The stalks terminate in compound umbels of flowers about 1½-3½" across that are flat-topped. Each compound umbel is divided into 10-20 umbellets, while each umbellet is divided into 10-25 flowers. The compound umbels lack floral bracts and the umbellets lack floral bractlets. Individual flowers are about 1/8" (3 mm.) across, consisting of 5 white petals with incurved tips and an inferior ovary with a pair of styles. The peduncles of the compound umbels are 3-6" long, light green, glabrous, angular, and grooved. The pedicels of individual flowers are about ¼" in length, light green, and glabrous. The blooming period occurs from late spring to mid-summer, lasting about 1 month. The flowers are replaced by ovoid-oblongoid fruits that are ridged and somewhat flattened; they are about 1/8" (3 mm.) long and release their seeds at maturity during the autumn. The root system is fibrous and rhizomatous. Goutweed often forms clonal colonies from the spreading rhizomes. [图片]Cultivation: The preference is partial sun to light shade, moist to mesic conditions, and soil containing loam, clay-loam, or sandy loam. This plant has few problems with either insects or disease organisms. It can spread aggressively, particularly in locales with cool moist climates. [图片]Range & Habitat: So far, Goutweed has rarely escaped from cultivation and become naturalized in Illinois. It has been found as an escaped plant in only a few counties of NE Illinois (see Distribution Map). Because of its aggressive nature, Goutweed may become more common in the future. It was introduced into North America from Eurasia as an ornamental plant. Habitats include deciduous woodlands (sandy & non-sandy), shaded ravines, woodland borders, cemeteries, roadsides, and waste areas. Cultivated forms of Goutweed include those with variegated and non-variegated leaves. However, wild specimens of Goutweed almost always have non-variegated leaves. Faunal Associations: Floral-faunal relationships for this plant in North America are poorly understood. Müller (1873/1883) observed miscellaneous flies, beetles, wasps, small bees, and sawflies visiting the flowers for either nectar or pollen in Germany. Apparently the young foliage of Goutweed is considered edible to humans as it has been used in the Old World as a source of food and a medicinal herb. [图片]Photographic Location: A flower garden in Urbana, Illinois. Comments: Like many other species in the Carrot family, Goutweed has compound umbels of small white flowers and compound leaves. It can be identified by the absence of floral bracts and bractlets underneath its flowers, and by the structure and shape of its leaves. Generally, its compound leaves have ternately arranged leaflets (divided into groups of 3), although the leaflets within a group sometimes occur in pairs. Compared with many other species in the Carrot family, these leaflets are relatively large in size and relatively broad in shape when one considers the size of the plant. Among native wildflowers, Honewort (Cryptotaenia canadensis) is similar in appearance to Goutweed, but the flowers of Honewort are even smaller in size and its compound leaves have only 3 leaflets, rather than 3 groups of leaflets.

Carrots are a root vegetable. This means that humans typically only eat the orange edible taproot--main plant root--and not the edible leafy greens that are above ground. Carrots are not part of the typical annual--one year--or perennial--many repetitive years--plant cycles. Carrots are actually classified as biennials, according to the World Carrot Museum. [图片]What is a Biennial? Wet Carrots in the dirt credit: HandmadePictures/iStock/Getty Images Biennials like carrots live for two growing seasons before the completion of their life cycle, according to the University of Illinois Extension. Biennial plants grow vegetatively--produce leaves--for the first season of life. After a period of dormancy--rest without growth--following the first season of growth biennials resume growth for a second season, flower, seed and die. Germination [图片]Carrot plants produce seeds during the second season of biennial growth. Pollen is produced and delivered to the stigma, according to the WCM. The plant then produces seed. Carrot seeds are exceptionally small: 2000 seeds can fit in a single teaspoon. Carrot seeds take 10-12 days to germinate and begin growth. Growth [图片]Carrots will grow leafy green shoots from the taproot. These shoots are where flowering happens during the second season of growth. Carrots are usually prime for harvesting within three months, states the WCM; however, carrots can and frequently are harvested early. Baby carrots are merely immature carrots, but baby-cut carrots are mature carrots shaved to baby size. Dormancy [图片]The period of carrot dormancy between seasons is typically winter in most areas the carrot is cultivated. Carrots growth is essentially complete when it enters dormancy, and flowering may not happen if dormant states experience interruption from unseasonably warm winters or late frosts. Carrots need a dormant state to prepare for the reproduction period. Carrot Variants [图片]Carrots are available in a variety of cultivars--varieties human-cultivated for different traits--that produce different shapes and colors of carrots. Some carrots--such as Thumbelinas--are very short and some--such as White Fodder--are not orange in color, according to the WCM. Many colors and shapes of carrot cultivars are available to discernible growers seeking particular carrot results.

Okra, also known as gumbo, is a warm-weather vegetable that thrives in the long, hot summers of the southern United States. Although okra loves hot weather, it can successfully be grown in cooler Northern climates as well. Plant okra seeds directly in your garden seven to 10 days after the last expected frost in your area, as the seeds won't grow in cold weather. Okra will be ready to harvest approximately 60 days after planting. [图片]Step 1 Spade the soil in a sunny area in your garden. Work the soil to a depth of at least 6 inches, then work in an all-purpose granular fertilizer with a ratio such as 10-10-10. Apply 1 to 2 lbs. of fertilizer for every 100 square feet of garden space. Step 2 Make shallow rows with the corner of your hoe. Allow 3 feet between each row. Plant the okra seeds 4 to 6 inches apart in the rows, then cover the seeds with 1 inch of soil. Water lightly with a hose and spray attachment. Step 3 Thin the okra seedlings when the plants are 2 to 4 inches tall. Allow 12 to 18 inches between each plant. Step 4 Water okra deeply enough to saturate the soil once every seven to 10 days during extended hot, dry periods. Otherwise, okra requires no irrigation. [图片]Step 5 Harvest okra with kitchen shears or a sharp knife when the pods are 2 to 4 inches long. Okra ripens quickly in late summer so check the plants every two to three days. Handle the pods gently as okra is tender and bruises easily. Pick regularly, as the plant will go to seed and won't continue to produce if the pods are allowed to remain on the plant.

Onions are ideally suited for container gardening. Even a 6- to 10-inch container is large enough to get started, and can fit easily on a balcony or doorstep. Growing onions in containers is a perfect solution for space-challenged gardeners. As an added bonus, container gardening is easy on sore knees and backs as very little bending and stooping is required. Plant onions in spring and in a few weeks you'll have fresh, delicious onions. [图片]Step 1 Purchase onion sets at a nursery or garden center. Sets, which are small onions that were started the previous year, are the easiest and most effective way of planting onions in containers. Small sets, which are smaller than a dime, are best for growing large onions for use in cooking or for slicing. Sets larger than a dime are best for growing small green onions often used in salads, and will be ready for harvest very quickly. Sets can be planted in March or April. Step 2 Prepare a container at least 6 to 10 inches in diameter. Any container with drainage holes in the bottom will work. Fill the container with any good quality commercial potting soil. Step 3 Plant large onion sets about 1 inch below the surface of the soil. Plant the sets close enough to touch, as the green onions will be harvested before crowding becomes problematic. Small sets, which will be used for large, dry onions, should be planted with 2 to 4 inches between each set. Step 4 Water the onions immediately. Check the moisture daily by poking your finger into the top of the soil. If the top inch of the soil is dry, water the onions until water runs through the drainage hole. Don't water again until the top inch of the soil is dry. During hot, dry weather, onions may need water every day.
