Help, my crabapple isn’t flowering! Crabapple trees put on a real show in springtime with dense masses of blossoms in shades ranging from pure white to pink or rosy red. When a flowering crabapple has no flowers, it can be a huge disappointment. There are several possible reasons for a crabapple not blooming, some simple and some more involved. Read on for tips on troubleshooting flowering crabapple problems.
Reasons for No Flowers on Crabapple Trees Age: When a young crabapple isn’t flowering, it may be because the tree still needs a few more years to grow and mature. On the other hand, an old tree may be past its best blooming years. Feeding: Although crabapple trees don’t need a lot of fertilizer, they benefit from one light feeding every spring during the first four or five years. Sprinkle a time-release fertilizer on the ground under the tree, out to about 18 inches past the dripline. Mature trees require no fertilizer, but a 2- to 4-inch layer of organic mulch will return nutrients to the soil.
Weather: Crabapple trees can be fickle when it comes to the weather. For example, a dry autumn may result in no flowers on crabapple trees the following spring. Similarly, crabapple trees require a chilling period, so an unseasonably warm winter may create flowering crabapple problems. Erratic weather may also be to blame when one tree blooms and a neighboring tree in the same yard doesn’t, or when a tree displays only a few half-hearted flowers. Sunlight: Crabapple trees require full sunlight and a too shady location may be the culprit when a crabapple isn’t flowering. Although crabapples don’t require heavy pruning, proper pruning in spring can ensure sunlight reaches all parts of the tree.
Disease: Apple scab is a common fungal disease that affects leaves when they emerge in spring, particularly when conditions are moist. Replace the tree with a disease-resistant cultivar, or try treating the affected tree with a fungicide at leaf emergence, followed by treatments two and four weeks later.

Crabapples are popular, adaptable trees that add all-season beauty to the garden with minimal maintenance. Picking a crabapple tree is a bit of a challenge, however, because this versatile tree is available in a tremendous range of flower color, leaf color, fruit color, size and shape. Read on to learn about choosing crabapple trees for landscapes.
Popular Crabapple Varieties There are both fruiting crabapple trees and non-fruiting crabapples. While most flowering crabapples develop fruit, there are a few varieties that are virtually fruitless. Below are some common types of crabapples to choose from: Fruiting Crabapples Golden Hornet – This is an upright variety that produces white to pale pink blooms followed by greenish-yellow fruit. The foliage turns from medium green to yellow in fall. Snowdrift – This rounded form produces pink buds that bloom white. Its orange fruit is followed by bright yellow autumn colored leaves. Sugar Tyme – Having an oval-like shape, this crabapple tree has pink flowers with deep red crabapple fruit. It, too, changes from green to yellow in fall.
Sparkling Sprite – Another rounded variety, this one has yellow to golden-orange fruit and its fall foliage is an attractive deep red. Donald Wyman – Turning a golden yellow in fall, this rounded crabapple tree produces white blooms and red fruit early on. Sargent Tina (Dwarf) – If you’re lacking for space, then this round, dwarf form may be just the tree you need. With stunning red spring blossoms followed by bright red fruit, it makes an attractive specimen. Callaway – Another white-flowering crabapple with red fruit, this variety consists of an oval, round shape and produces attractive fall foliage in shades of yellow, orange and red. Adams – This crabapple has a rounded to pyramidal shape with deep pink flowers and glossy red fruit. Its foliage is reddish in color, maturing to green and orange-red in fall.
Anne E – This is a weeping variety producing attractive rosy pink blossoms and bright red fruit followed by yellow fall foliage. Cardinal – Upright in form with rosy red flowers and deep red fruit. The foliage turns reddish-purple to red-orange in autumn. Ellen Gerhart – Another popular upright variety, this crabapple tree has pale pink blossoms and bright red fruit. Brandywine – This rounded variety produces pretty rosy pink blossoms followed by greenish-yellow fruit. You’ll also enjoy its green foliage that’s tinted with red and changes an orange to yellow color in autumn. Centurion – This is a columnar crabapple that produces rosy red blooms and red fruit. The fall leaves may be reddish-green to yellow-orange. Cinzam (Dwarf) – Another dwarf rounded variety, it produces white blossoms that are followed by golden yellow fruit. Velvet Pillar – An upright crabapple tree that produces pink flowers and maroon colored fruit. In autumn, the foliage takes on purple and orange-red hues. Adirondack – This oval formed crabapple has pure white blooms followed by orange-red fruit. Autumn color may be mottled green to yellow.
Non-Fruiting Crabapples Merilee – A narrow, upright variety, this crabapple bears white blossoms. Prairie Rose – A rounded, medium-green tree with deep pink flowers. Spring Snow – An oval form variety having pure white blooms.

Home gardeners usually select crabapple trees to complement the landscape with a compact tree, for flowers or for pretty foliage, but like other ornamental trees, crabapple fruit will appear in the right season.
Do Crabapple Trees Produce Fruit? Crabapple trees are great ornamental choices for a variety of settings, and most are hardy across a wide climate range. Most people choose crabapples for their smaller size and for the pretty white or pink flowers that they produce in spring. Of secondary consideration is the fruit on a crabapple tree, but most will produce them. By definition, a crabapple is two inches (5 cm.) or less in dimeter, while anything larger is just an apple.
When Do Crabapples Fruit? The fruit on a crabapple tree can be another layer of ornament in your yard. The flowers are often the first draw for this kind of tree, but crabapple fruit comes in a variety of colors and add visual interest when they form in the fall. The foliage will also turn color, but the fruits often persist long after the leaves come down. Fall fruit colors on crabapples include bright, glossy red, yellow and red, yellow only, orange-red, deep red, and even yellow-green depending on the variety. The fruits will also keep birds coming to your yard for fruit well into late fall. Of course, crabapples aren’t just for the birds to enjoy. Are crabapples edible to humans as well? Yes, they are! While on their own, they may not taste that great, several varieties of crabapple fruit are wonderful for making jams, jellies, pies and the like.
Are There Fruitless Crabapple Trees? There is a variety of crabapple tree that does not produce fruit. If you like these ornamental trees but aren’t interested in picking up all the rotting apples from underneath them, you can try a ‘Spring Snow,’ ‘Prairie Rose,’ or ‘Marilee’ crabapple. These are unusual for being fruitless crabapple trees, or mostly fruitless anyway. Except for ‘Spring Snow,’ which is sterile; they may produce a few apples. These fruitless varieties are great for walkways and patios, where you don’t want fruit underfoot.
Whether you like the idea of crabapple fruits in your garden or not, this compact ornamental tree is a beautiful and flexible option for landscaping. Choose from several varieties to get the flowers and fruit you like best.

Who among us hasn’t been told at least once not to eat crabapples? Because of their frequently bad taste and small amounts of cyanide in the seeds, it’s a common misconception that crabapples are toxic. But is it safe to eat crabapples? Keep reading to learn more about the safety of eating crabapples and what to do with crabapple fruit trees.
Are Crabapples Edible? The short answer to this question is: yes. But there’s a longer answer to explain why. Crabapples aren’t actually a different kind of tree than apples. The only distinction is one of size. If a tree produces fruits that are bigger than two inches (5 cm.) in diameter, it’s an apple. If the fruits are smaller than 2 inches, it’s a crabapple. That’s it. Granted, those apples that have been bred to be bigger have also been bred to be better tasting. And many ornamental varieties of crabapples have been bred to have attractive flowers and nothing else. This means that the fruit of crabapple trees, for the most part, is not especially good tasting. Eating crabapples won’t make you sick, but you may not enjoy the experience.
Eating Fruit of Crabapple Trees Some crabapple fruit trees are more palatable than others. Dolgo and Centennial are varieties that are sweet enough to eat right off the tree. For the most part, however, crabapple owners prefer to cook the fruit into preserves, butters, sauces, and pies. A couple good varieties for cooking are Chestnut and Whitney. Crabapple trees hybridize readily, so if you have a tree on your property, there’s a decent chance you’ll never know quite what it is. Feel free to experiment with eating it fresh and cooking it with lots of sugar to see if it tastes good.
You don’t have to worry about whether it’s edible – it is. And as for the cyanide? It’s just as present in the seeds of apples and even pears. Just avoid the seeds as usual and you’ll be fine.

Crabapple trees are pretty easy to maintain and don’t require vigorous pruning. The most important reasons to prune are to maintain the tree’s shape, to remove dead branches, and to treat or prevent the spread of disease.
When to Prune a Crabapple Tree The time for crabapple pruning is when the tree is dormant, but when the possibility of severely cold weather has passed. This means pruning should be done in late winter or early spring, depending on your local climate and temperatures. Suckers, the little shoots that come straight out of the ground around the base of the tree, can be pruned away at any time of year.
How to Prune Crabapples When pruning crabapple trees, start by removing suckers and water sprouts. The suckers grow from the rootstock of your tree and if you allow them to develop, they can grow into new trunks, possibly of a completely different tree type. This is because your crabapple was grafted onto the rootstock of a different variety. Water sprouts are small shoots that emerge at an angle between some of the main tree branches. They don’t usually produce fruit and crowd other branches, increasing the risk of disease spreading from one branch to another. The next step in cutting back crabapple trees is to remove any dead branches. Remove them at the base.
Once you have taken off any dead branches, water sprouts, and suckers, you have to be a little more judicious about what to remove next. Remove branches to create a pleasing shape, but also consider removing branches to help them stay well-spaced from each other. Crowded branches make the spread of disease easier. You may also want to remove branches that hang too low and impede movement under the tree, especially if planted in an area frequented by passersby.
Just remember to keep your crabapple pruning simple and minimal. This tree doesn’t require heavy pruning, so take your time and consider how you want it to look before you start removing branches.

Exotic plants like the coral tree lend unique interest to the warm region landscape. What is a coral tree? The coral tree is an amazing tropical plant that is a member of the legume family, Fabaceae. It may be spiny or smooth, deciduous or evergreen, with a spectacle of a flower in brilliant pink, red or orange hues. Growing coral trees is only appropriate outdoors in USDA zones 9 and up. Coral tree care is easy if you are in the correct region, but some growers may find them messy. Find out how to grow coral trees and add some of their intense beauty to your garden.
What is a Coral Tree? Coral trees are members of the genus Erythrina and are primarily found in South Africa and South America. There are approximately 112 different species of Erythrina around the world. They are also found in Mexico, Central America, the West Indies, Asia, Australia and even Hawaii. The wide area covered by the plants seems to indicate coastal dispersal of seeds. Some interesting coral tree information regards their extremely buoyant seeds, which have the ability to float for up to one year and are so hard they pass unharmed through animal and bird digestive tracts. These tough seeds wind up tossed from surf on fertile tropical soils where they take off and eventually adapt and evolve to take advantage of their environment.
Coral Tree Information The average height of a coral tree is 35 to 45 feet tall, but some varieties exceed 60 feet in height. The leaves have three distinct leaflets and the stems may have thorns or may be smooth, depending upon their evolutionary adaptations. The trees have a thick trunk, usually with several smaller trunks joining the main stem. Roots push out of the ground as they age and may become a hazard. The bark is a thin grayish brown and the wood is pithy and weak, prone to breaking in the wind or due to overwatering. The flowers are the standout, appearing in late winter. They are outlandish constructions of thick bright pedals standing erect around the corolla. Hummingbirds are extremely attracted to the loud colors and striking scent.
Coral Tree Care Coral trees need very little water. Too much water actually promotes a weak limb structure and subsequent breakage. Overwatering causes the tree to grow too quickly, and its soft wood cannot support such spurts. Then in the dry season, the weight of the tree can actually pull it out of the soil. Pruning the tree in spring to remove the heavier stems or any damaged material will help prevent limb loss and trees from tipping.
Fertilizer is also not recommended when growing coral trees. Fertilizer also causes them to have aggressive growth that can cause problems later. Cover over the root zone with a good organic mulch, which will gradually leach a light dose of nutrients into soil over time.

The names Colorado spruce, blue spruce and Colorado blue spruce tree all refer to the same magnificent tree—Pica pungens. Large specimens are imposing in the landscape because of their strong, architectural shape in the form of a pyramid and stiff, horizontal branches that form a dense canopy. The species grows up to 60 feet tall and looks best in open, arid landscapes, while smaller cultivars that grow 5 to 15 feet tall are right at home in lush gardens. Continue reading for information on how to grow a Colorado blue spruce.
Colorado Spruce Info Colorado blue spruce is a Native American tree that originated on stream banks and crags of the western United States. This sturdy tree is grown in farmlands, pastures and large landscapes as a windbreak and doubles as a nesting site for birds. Dwarf species are attractive in home landscapes where they look great in shrub borders, as backdrops for borders and as specimen trees. Short, sharp needles that are square in shape and very stiff and sharp attach to the tree singly rather than in bunches, like pine needles. The tree produces 2- to 4-inch brown cones that fall to the ground in autumn. They are distinguished from other spruce trees by the bluish color of the needles, which can be quite striking on a sunny day.
Colorado Blue Spruce Planting Guide Colorado blue spruce grows best in a sunny location with moist, well-drained, fertile soil. It tolerates dry wind and can adapt to dry soil. The tree is hardy in USDA plant hardiness zones 3 through 7. Plant Colorado blue spruce in a hole that is as deep as the root ball and two or three times as wide. When you set the tree in the hole, the top of the root ball should be even with the surrounding soil. You can check this by placing a yardstick or flat tool handle across the hole. After adjusting the depth, firm the bottom of the hole with your foot.
It’s best not to amend the soil at planting time, but if it is poor in organic matter, you can mix a little compost with the dirt that you removed from the hole before backfilling. Compost should make up no more than 15 percent of the fill dirt. Fill the hole half full with the fill dirt and then flood the hole with water. This removes air pockets and settles the soil. After the water has drained through, finish filling the hole and water thoroughly. If the soil settles, top it off with more dirt. Do not mound soil around the trunk.
Caring for Colorado Spruce Caring for Colorado spruce is simple once the tree is established. Water it regularly to keep the soil moist through the first season and only during dry spells thereafter. The tree benefits from a 2-inch layer of organic mulch that extends just beyond the tips of the branches. Pull the mulch back a few inches from the base of the tree to prevent rot. Colorado blue spruce is susceptible to cankers and white pine weevils. The weevils cause the leaders to die back. Cut off dying leaders before the damage reaches the first ring of branches and choose another branch to train as a leader. Stake the new leader into an upright position.
Some insecticides remove the wax coating on the needles. Since the wax is what gives the tree its blue color, you want to avoid this if at all possible. Test insecticides on a small, inconspicuous part of the tree before spraying the entire tree.

Clove trees (Syzygium aromaticum) produce the cloves you use to spice up your cooking. Can you grow a clove tree? According to clove tree information, it’s not hard to grow these trees if you can provide ideal growing conditions. If you are wondering what it takes to grow this tree or about clove tree uses, read on.
Clove Tree Information The clove tree is native to Indonesia, but clove tree information suggests that it has naturalized in many warm countries. These include Mexico, Kenya and Sri Lanka. The plant has been cultivated since 200 B.C. to produce the cloves. The most important of clove tree uses is, of course, the plant’s aromatic dried buds, or cloves. The name cloves comes from Latin “clavus,” meaning nail, as cloves often look like small nails. Clove trees are evergreens that grow to some 40 feet tall. Their bark is smooth and gray, and their long, 5-inch leaves look like bay leaves. Blossoms are tiny – about ½ inch long – and gather in clusters at branch tips. The entire plant is fragrant and aromatic.
Clove Tree Growing Conditions Can you grow a clove tree? You can, but it’s hard for most gardeners to replicate ideal clove tree growing conditions. Clove tree information tells you that the tree is native to wet, tropical areas of the world. Therefore, the trees grow best in a hot and wet region. Ideal growing conditions include at least 50 to 70 inches of rainfall annually. The minimum temperature for clove trees is 59 degrees Fahrenheit (15 C.). Most commercial clove producers locate their plantations within 10 degrees of the equator.
Clove Tree Care If you happen to live in such an area, and near the ocean, you probably won’t have much trouble growing clove trees. Plant the seeds in well-drained, fertile loam, then follow good practices for their care. One part of clove tree care is to install shade plants to protect the young seedlings for the first few years. Banana plants work well to provide this temporary shade. Clove trees are not a short-term project. The trees regularly live a century and sometimes live for over 300 years. More pertinent to the average gardener, you’ll have to wait at least 20 years for the tree to produce a full crop.
Clove Tree Uses Many Americans use cloves for cooking. They are popular spices for baked hams and pumpkin pie. But clove tree uses are much broader than this globally. In Indonesia, cloves are used to make popular clove aromatized cigarettes. Other clove tree uses are medicinal. Extracted clove oil is also used as an essential oil that is used medicinally. Some people also make tea from cloves that is considered to help with stomach upsets, chills and impotence.

Palm trees have a distinctive tropical flavor, but most of them become 60-foot tall or more monsters. These huge trees are not practical in the private landscape due to their size and the difficulty of maintenance. The Christmas tree palm poses none of these problems and comes with the characteristic silhouette of its bigger cousins. Growing Christmas palm trees in the home landscape is a perfect way to get that tropical feel without the hassle of the bigger specimens in the family. Let’s learn more about these palms.
What is a Christmas Palm? The Christmas palm (Adonidia merrillii) forms a lovely smaller tropical tree suitable for home landscapes. What is a Christmas palm? The plant is also known as the Manila palm or dwarf Royal. It is native to the Philippines and useful in United States Department of Agriculture zone 10. The tree only gets 20 to 25 feet in height and is self-cleaning. Lucky warm season gardeners should know how to grow Christmas palm tree for diminutive tropical flair but easy maintenance. The Christmas palm gets started growing with a bang, achieving 6 feet in height quite rapidly. Once the tree is established to its site, the growth rate slows down considerably. The smoothly ridged trunk can grow 5 to 6 inches in diameter and the tree’s elegantly bowed crown may spread out to 8 feet.
Christmas tree palms bear arching pinnate leaves that may approach 5 feet in length. One of the more interesting Christmas palm tree facts is why it came by its name. The plant bears bright red clusters of fruits that ripen just about the same time as the Advent season. Many gardeners consider the fruit a debris nuisance, but removing them before ripening usually solves any messy issues.
How to Grow a Christmas Palm Tree Landscapers like to plant these trees quite close together because they have small root balls and will produce a natural looking grove. Be aware that growing Christmas palm trees too close can cause some of them to fail to thrive due to excess competition. Planting in too little light can also produce spindly trunks and sparse fronds. If you want to try growing your own Christmas tree palm, collect seeds in late fall to early winter when they are ripe. Clean off the pulp and immerse the seed in a solution of 10% percent bleach and water. Plant seeds shallowly in flats or small containers and place them in a location with temperatures of 70 to 100 degrees Fahrenheit (21 to 37 C.). Keep the container moist. Germination in Christmas tree palm seeds happens fairly rapidly and you should see sprouts in just a few weeks.
Christmas Palm Tree Care This tree prefers well-drained, slightly sandy soil in full sun, although it can tolerate light shade. The plants require supplemental water as they establish, but once mature, these trees can withstand short periods of drought. They are also quite tolerant of saline soils. Fertilize every 4 months with a time release palm food. Because the plants are self-cleaning, you rarely have to do any pruning.
The palms are susceptible to Lethal Yellowing. This disease will eventually take the palm. There is a preventative inoculation that is administered before the plant contracts the disease. A few fungal diseases are also of concern; but for the most part, Christmas palm tree care is a piece of cake, which is why the plant is so popular in warm climates.

Golden chinquapin (Chrysolepis chrysophylla), also commonly called golden chinkapin or giant chinquapin, is a relative of chestnuts that grows in California and the Pacific Northwest of the United States. The tree is easily identifiable by its long, pointy leaves and spiky yellow nuts. Keep reading to learn more chinquapin information, such as caring for chinquapins and how to grow golden chinquapin trees.
Golden Chinquapin Information Golden chinquapin trees have a very broad height range. Some are as small as 10 feet (3 m.) high and are really considered to be shrubs. Others, however, can grow to as tall as 150 feet. (45 m.). This huge variance has to do with elevation and exposure, with the shrubbier specimens usually found at high elevations in harsh, windswept conditions. The bark is brown and very deeply furrowed, with ridges that are 1 to 2 inches (2.5-5 cm.) thick. The leaves are long and spear shaped with distinctive yellow scales on the underside, earning the tree its name. The tops of the leaves are green. The tree produces nuts that are enclosed in bright yellow, spiny clusters. Each cluster contains 1 to 3 edible nuts. The trees range natively throughout coastal California and Oregon. In the state of Washington, there are two distinct stands of trees that contain golden chinquapins.
Caring for Chinquapins Golden chinquapin trees tend to perform best in dry, poor soil. In the wild, they are reported to survive in temperatures ranging from 19 F. (-7 C.) to 98 F. (37 C.). Growing giant chinquapins is a very slow process. A year after planting, seedlings may be only 1.5 to 4 inches (4-10 cm.) tall. After 4 to 12 years, the seedlings usually only reach between 6 and 18 inches (15-46 cm.) in height.
The seeds do not need to be stratified and can be planted immediately after harvest. If you are looking to collect golden chinquapin seeds, look into the legality of it first. Your local county extension office should be able to help with that.
