What is bog rosemary? It is a marsh plant very different from the rosemary you cook with in the kitchen. Bog rosemary plants (Andromeda polifolia) thrive in boggy habitats like wet swamps and dry bog moss hummocks. Read on for more information on bog rosemary plants, including tips for bog rosemary growing.
What is Bog Rosemary? Bog rosemary plants, also known as marsh Andromeda because of the species name, are creeping evergreens. Low to the ground (no taller than a couple of feet), they thrive in soggy areas in the landscape. This native is found growing wild in the northeast United States. It also is native to parts of Europe and Asia. The new growth of these marsh Andromeda shrubs is usually lime green, although sometimes you find reddish hues. The growth is covered with a waxy film, and matures into a deep green or blue green with pale downy undersides. The leaves of bog rosemary plants are shiny and leathery. The foliage contains andromedotoxin, a powerful poison, so bog rosemary plants are rarely nibbled on by animals. Bog rosemary blossoms are unusual flowers. You’ll see a half-dozen tiny urn-shaped flowers growing together in a cluster at each stem tip. The flowers appear in May, each about ¼ inch long and pale pink. The fruits of marsh Andromeda are small bluish dried capsules that turn brown in October. Neither the flowers nor the seeds are particularly showy.
Bog Rosemary Growing If you have a perpetually wet corner of the garden, bog rosemary growing might be just the thing. True to its common names, marsh Andromdea loves and thrives in marshy areas. Don’t worry about spending a lot of time on bog rosemary care either. If you place this shrub in an appropriate site, bog rosemary care takes very little effort.
When you have bog rosemary growing in a boggy spot in your backyard, you’ll find that it spreads quickly and requires little, if any, assistance. The plant tolerates compacted soil, wind and ice, preferring a location in U.S. Department of Agriculture plant hardiness zones 3 through 6. Another reason you won’t have to spend too much time on bog rosemary care: the plant has few disease or insect troubles. You don’t need to fertilize or prune it.

There’s nothing as annoying in the garden pond as watermeal. This tiny, loathsome plant can quickly take over, ruining your beautiful landscape and forcing yet another manual cleaning of your pond to clear it up. Learn some easier ways to manage watermeal weeds long term in this informative article.
What is Watermeal? Experienced garden pond owners shutter when the name is uttered because watermeal in ponds is big trouble for the backyard gardener. This aquatic weed can be a serious pain, but watermeal in ponds doesn’t have to mean draining your pond, yet again, to kill it back. There are several methods of effective watermeal control that work against the plant’s basic biology. Watermeal (Wolffia spp.) are holds the unique position as the world’s smallest flowering plant, but it’s also one of the world’s most annoying pond weeds. This 1 to 1 1/2 millimeter long, grain-like plant is commonly found embedded among colonies of duckweed, where it’s barely visible to the naked eye. If you dip your hand into the pond, remove some of the duckweed and rub it between your palms, you’ll feel a grainy sensation – that’s the watermeal. It can occur on its own, but this is a much less common situation. Watermeal removal is most effective with a two-fold approach that includes eliminating the material that the watermeal is feeding on and employing pond creatures to feed upon the weed itself. Prevention is a much easier process than control, but both require the same tactics. Once watermeal is choking the pond, it may be much easier to drain the pond and clean it completely before implementing protective measures.
Controlling Watermeal Weeds Watermeal feeds greedily off of rotting material on the bottom of your pond. This black sludge may not look like much to you, but for watermeal, it’s a veritable buffet. Any program of watermeal control has to include management of that build-up, so if there’s fertilizer or agricultural run-off moving into your pond, or the leaves from the tree above end up in your pond every year, the first step is to slow this input. Surface netting can help trap leaves, or you can fish them out of the pond daily with a pool net. Run-off may be slowed by building an earth berm around the pond. Once the addition of nutrients is managed, it’s a good idea to add a bubble aerator to the deepest area in the bottom of your pond to eliminate the stratification. The lack of oxygen in deeper waters can make it hard for bacteria to break down whatever waste does accumulate. By adding a bubbler, you’ll increase oxygen and pond circulation so that your pond plankton can consume the excess nutrients before watermeal has a chance to set in.
While the watermeal is at least somewhat controlled, you’ll want to introduce pond fish that eat this plant, like koi or grass carp. Koi will eat watermeal readily, while grass carp may eat other plants first. Another option is to add a couple of ducks to the landscape. They’ll readily gobble up this annoying plant pest as long as it’s kept reasonably in check by other methods.

Graceful and elegant, water lilies (Nymphaea spp.) are a wonderful addition to any water garden. But if your water lily is not hardy for your climate, you may be wondering how to winterize water lily plants. Even if your water lilies are hardy, you might be wondering what you should do for them to help them make it through winter. Winter care for water lily plants does take a little bit of planning, but is easy to do once you know how. Keep reading to learn more about how to over winter water lilies.
How to Winterize Water Lily Plants The steps for wintering water lilies actually starts long before winter actually arrives, regardless of whether you grow hardy or tropical water lilies. In late summer, stop fertilizing your water lilies. This will signal to your water lily plants that it’s time to start getting ready for cold weather. A few things will happen after this. First, the water lily will start to grow tubers. This will provide food for them over the winter. Second, they will start to die back and enter dormancy, which slows their systems down and helps keep them safe over winter. The water lilies will typically grow small leaves at this time and their larger leaves will turn yellow and die. Once this occurs, you are ready to take steps for wintering your water lilies.
How to Store Water Lilies Over Winter Wintering Hardy Water Lilies For hardy water lilies, the key to how to over winter water lilies well is to move them to the deepest part of your pond. This will insulate them a little from repeated freezing and unfreezing, which will decrease your water lily’s chance of surviving the cold. Wintering Tropical Water Lilies For tropical water lilies, after the first frost, lift the water lilies from your pond. Check the roots to make sure that the plant has properly formed tubers. Without tubers, it will have a difficult time surviving the winter.
After you have lifted your water lilies from the pond, they need to be placed in water. The containers people use to store their water lilies over winter varies. You can use an aquarium with a grow or fluorescent light, a plastic tub under lights or in a glass or plastic jar placed on a window sill. Any container where the plants are in water and get eight to 12 hours of light will work. It’s best to store your water lilies bare rooted in the water and not in growing pots. Replace the water weekly in container and keep the water temperature around 70 F. (21 C.). In the spring, when the tubers sprout, replant the water lily in a growing pot and place out into your pond after the last frost date has passed.

Water lilies (Nymphaea spp.) are the perfect finishing touches for a garden pool or pond, adding practicality as well as beauty to a water feature. Fish use them as hiding places to escape predators and as shady retreats from the hot summer sun. Plants growing in a pond help keep the water clean and aerated, so you’ll spend less time on pond maintenance. Let’s take a look at how to grow a water lily.
Water lily plants can be divided into two types: Hardy – Hardy types are best for northern climates where the water freezes in winter. As long as the roots of hardy specimens are below the level where the water freezes, they will reappear the following spring. Tropical – Tropical water lilies won’t survive in cold water and must be brought indoors for winter in all but the warmest areas. Many growers treat them as annuals, replanting them each year. Otherwise, remove them from the pond, clean them up, and store them in a bucket of moist sand in a cool basement before the first freeze. Tropical water lily plants can be further divided into two groups: day bloomers and night bloomers. White night bloomers look spectacular with nothing more than moonlight to illuminate them, but blues, purples, reds and pinks are very difficult to see in the dark. Avoid these colors unless the pond is illuminated by artificial light at night.
How to Grow a Water Lily A pond or pool covered in water lilies is attractive, but complete coverage prevents light from penetrating into the water, choking out other plant and animal life. Growing water lilies in containers helps keep them from spreading and taking over a small pond and it makes water lily care much easier. When you are growing water lilies, use a large plastic pot with several holes punched in the sides and bottom. Fill the pot to within 3 inches of the top with silt, loam or clay soil and mix in a small amount of slow-release fertilizer labeled for use with aquatic soil. Plant the rhizome close to one side of the pot at a 45-degree angle with the eye pointing up. Cover the soil with a layer of pea gravel, keeping the gravel away from the top of the rhizome as much as possible. The gravel keeps the soil from floating off or washing out of the pot.
Place the pot in the bottom of the pond, adjusting the depth to that recommended for your specific variety. Most call for a depth of between 6 and 18 inches. If necessary, you can raise the depth by placing the pot on top of rocks. NOTE: For those having fish in their water garden, water lilies should NOT be potted in regular potting soil, as this contains a lot of organic material that will eventually rot and foul the water. Remove any rotting organic material from your pond or water garden, as this is a breeding ground for anaerobic bacteria and pathogens and may add unwanted excess nutrients to feed algae blooms. Instead, pot water lilies, and any other pond plant, in a heavy clay soil and cover with fist sized rock, and then river rock to prevent fish from rooting around in the pot and sending the planting medium into the pond. A few simple preventative steps up front are far easier to take than trying to treat sick and dying fish later.

Beautiful but destructive in the wrong environment, water hyacinths (Eichhornia crassipes) are among the showiest of water garden plants. Flower stalks that grow about six inches above the foliage arise from the centers of the rosettes in spring, and by the end of spring, each plant holds as many as 20 gorgeous purple flowers. The flowers last until fall and make striking cut flowers.
How to Grow Water Hyacinth Growing water hyacinth plants is easy. Once established, they require no special care except occasional thinning to keep them from choking out everything else in the pond. Under perfect conditions, a colony of water hyacinths can double its size every 8 to 12 days. Water hyacinths need full sun and hot summer temperatures. Introduce them to the garden by scattering bunches of plants over the surface of the water. They quickly take hold and begin to grow. Thin the plants when they cover more than 60 percent of the water surface. Water hyacinth plants survive winters in U.S. Department of Agriculture plant hardiness zones 8 through 11. They are best grown as annuals in places where cold winters keep them in check by killing them back. In warmer areas, these plants do become invasive. You can overwinter them indoors in a sunny spot, but they are inexpensive to replace each year. Most gardeners don’t find them worth the trouble to keep over winter.
Container Grown Water Hyacinths A half barrel is an ideal container for a water hyacinth. The plants need full sun in garden ponds, but in containers they do best if they have shade from mid to late afternoon. Cover the inside of the barrel with a heavy duty garbage bag and then place a layer of soil in the bottom of the container. Don’t use commercial potting soil, which contains fertilizers and other chemicals that may harm the plant and encourage the growth of algae. Commercial soils also contain perlite and vermiculite, which floats to the top of the container. Cover the soil with a thin layer of sand. City water is usually treated with chlorine or chloramine, which is harmful to plants. Garden centers sell products that remove the chlorine and chloramine from the water and make it safe for plants. There is no need to treat the small amounts of water that you use to top off the container through the season.
You can allow the plant to float on the surface of the water, or anchor it in place by attaching one end of a length of nylon string to the plant and the other end to a brick.

The garden offers us a variety of beautiful plants to pick and choose between. Many are selected because of their prolific fruit production, while others attract us with insurmountable beauty. Water hyacinth is one of those plants that is deceptively gorgeous, delivering a serious payload to anyone unlucky enough to plant them in warm climates. Water hyacinth in ponds seems like a great idea when you plant them, but it won’t be long before you need major help.
Is Water Hyacinth Invasive? Although the brilliant purple water hyacinth isn’t yet federally listed as a noxious weed, plant and waterway experts the world over agree: this plant is bad news. The plant was initially spread because of its beautiful flowers, but the mistake of this particular decision was soon realized – after the damage couldn’t be undone. Now, water hyacinth threatens dams, waterways and wildlife across the globe, often forming dense mats so thick that a grown man can walk across them. So while it’s not legally considered invasive, water hyacinth control occupies a great deal of time in the minds of experts everywhere. These people would tell you that it’s only a matter of time before this plant is listed and regulated because of its aggressive nature.
How to Control Water Hyacinth If you’ve already been drawn in by the siren song of the water hyacinth, or a former owner of your property fell hard for this plant, you know the sheer determination it can exhibit. Managing water hyacinths is no small feat, but you can rid your garden ponds of these plants for good. The most effective methods so far found to control these plants include draining ponds completely, then removing and chopping up the plant (away from the pond, as even a small piece can regrow into new water hyacinths). Water hyacinth can then be composted, provided your compost pile is far from any water sources that could be affected by runoff, or double-bagged and thrown in the trash.
It may take several tries to rid your pond completely of water hyacinth, due to its weed-like behavior. If you’ve tried simply pulling this plant out of your pond in the past, without draining or cleaning the pond and equipment thoroughly, you’ve probably convinced yourself nothing will kill water hyacinth. However, by using an aggressive combination approach, you should be rid of your water hyacinth in no time.

Swamp mallow (Hibiscus moscheutos), also known as rose mallow hibiscus or swamp hibiscus, is a shrubby, moisture loving plant in the hibiscus family that provides big, showy flowers from mid-summer to autumn. The plant performs well along pond edges or other damp areas. This stunning, low-maintenance plant is available in a range of colors, including pink, peach, white, red, lavender and bi-color varieties.
How to Grow Rose Mallow The easiest way to grow rose mallow is to purchase a plant at a garden center or nursery. However, growing rose mallow by seed isn’t difficult. Start seeds indoors eight to 10 weeks before the last frost in your area, or plant seeds directly in the garden after the last killing frost in spring. Rose mallow benefits from rich soil amended with at least 2 or 3 inches of compost, manure or other organic material. Locate the plant in full sunlight. Although rose mallow tolerates partial shade, too much shade may result in leggy plants that are more susceptible to insect infestations. Allow at least 36 inches of growing space between each plant. Crowding the plant inhibits air circulation which may result in leaf spots, rust or other diseases.
Swamp Hibiscus Care Swamp hibiscus plants are water-loving plants that will stop blooming in dry soil. However, the plant, which dies and enters a dormant period in winter, shouldn’t be watered until it displays new growth in spring. Once the plant is actively growing, it needs a deep watering two or three times per week during warm weather. Water is especially important during the first growing season, but the plant should always be watered immediately if it shows signs of wilt.
Feed rose mallow every six to eight weeks during the growing season, using a balanced, water-soluble plant fertilizer. Alternatively, use a slow-release fertilizer after the plant breaks dormancy in spring. Spread 2 or 3 inches of mulch around the plant to keep the roots moist and cool, and to keep weeds in check. Spray swamp mallow with insecticidal soap spray if the plant is damaged by pests such as aphids, whiteflies or scale.

Pickerel rush (Pontederia cordata) is a native North American plant with a wide zone range in USDA plant hardiness zones 3 to 10. The plant may become invasive due to a rhizomous rooting system, but it is an attractive plant that bears blue spiked flowers from early summer well into fall. Pickerel rush care is easy and the tenacious plant is an unusual addition to riparian zones and along home ponds. Few tips are necessary to learn how to grow pickerel rush, but this semi-aquatic plant is worth a try if you plant it in a submerged pot to prevent unwanted spreading.
About Pickerelweed Plants Pickerelweed plants are rushes that are closely related to grasses. The plants are in the family Pontederia, named after an 18th century botany professor. These plants grow in clumps with thick to flat stems. The foliage is glossy and dark green with a heart-shaped leaf and grows 24 to 30 inches high. Stems on mature plants arch gracefully on water grown plants. The flower spires are a deep to soft blue and rise several inches above the body of the rush. Decorative and useful plants for around the home water feature should include pickerel rush for ponds because of its ease of care and hardiness. When the plant is partially submerged, the floating leaves provide important shade to prevent excess algae growth. They also form a network of foliage in which fish can hide.
How to Grow Pickerel Rush You can share new starts of the plant with friends easily. Divide the rhizomes in late winter to early spring. Simply dig up the plant or remove it from its pot. Use a clean sharp soil knife or pruners to cut apart the roots, leaving each piece with several healthy leaves and thick rhizomes. Replant the new clumps and they will take off quickly, increasing your pickerel weed inventory. You can also save and dry the seeds from the plant to start inside in flats in late winter. Seeded plants can take several seasons to produce the bright flowers. Caring for pickerelweeds once the seeds have germinated just requires consistent moisture and bright sunlight. Plant outside in spring.
Pickerel Rush Care Negligence is the word of the day in caring for pickerelweed plants. These unfussy little rushes can tolerate almost anything except full shade and drought. Pickerels should be kept in deep pots where the roots can remain moist. You can also submerge the entire pot and just let the broad leaves float out around the plant. Pickerel rush for ponds performs best when soils are heavy and rich. Loamy soils with moderate to slightly acidic pH create the best growing conditions for the plant. Pickerelweed plants that are grown in pots thrive in potting mix blended with a good quality topsoil and peat.

Super plant or invasive weed? The mosquito fern plant has been called both. So what is a mosquito fern? The following will uncover some fascinating mosquito fern facts and leave you to be the judge.
What is a Mosquito Fern? Native to California, the mosquito fern plant, Azolla filculoides or just Azolla, is named thus due to its habitat. While the plant starts off as small as ¼ inch, mosquito fern habitat is that of a matting, aquatic plant that can double its size in a couple of days! This thick-living carpet is named mosquito fern plant because it repels mosquito attempts to lay eggs in the water. The mosquitoes may not like mosquito ferns, but the waterfowl certainly do and, in fact, this plant is an important food source for them. This floating aquatic fern, like all ferns, propagates through spores. However, Azolla also multiplies by stem fragments, making it a prolific grower.
Mosquito Fern Facts The plant is sometimes mistaken for duckweed, and like duckweed, mosquito fern plant is initially green. It soon turns to a reddish-brown hue as a result of excess nutrients or bright sunlight. A red or green carpet of mosquito fern is most often found in ponds or muddy banks, or in areas of standing water in streams. The plant has a symbiotic relationship with another organism called Anabeana azollae; this organism is a nitrogen-fixing cyanobactrium. The bacterium resides safely in the fern and supplies it with the excess nitrogen it produces. This relationship has long been utilized in China and other Asian countries as a “green manure” to fertilize rice paddies. This centuries old method has been known to increase production by as much as 158%! So far, I think you will agree that this is a “super plant.” However, for some people, there is a down side. Because mosquito plant breaks apart so easily and, thereby, reproduces rapidly, it may become a problem. When there is an excess of nutrients introduced into the pond or irrigation water, either due to runoff or erosion, mosquito plant will seemingly explode in size overnight, clogging screens and pumps. Additionally, it is said that cattle will not drink from ponds that are clogged with mosquito fern. Now this “super plant” is more an “invasive weed.”
If the mosquito fern plant is more of a thorn in your side than a boon, you can try dragging or raking the pond to rid it of the plant. Keep in mind that any broken stems will likely multiply into new plants and the problem will likely repeat itself. If you can figure out a way to mitigate the amount of runoff to lessen the nutrients entering the pond, you can slow down mosquito fern’s growth somewhat. Of last resort is spraying Azolla with an herbicide. This isn’t highly recommended, as it only affects a small portion of the mat of fern and the resulting rotting plant can affect water quality.

If you’re in need of a good, easy-care plant that enjoys plenty of moisture, then growing lizard’s tail swamp lily may be just what you desire. Keep reading for lizard’s tail information and care.
Lizard’s Tail Information Lizard’s tail plants (Saururus cernuus), also known as lizard’s tail swamp lilies and Saururus lizard’s tail, are perennial plants that can grow up to 4 feet tall. They have a hairy stem with very few, if any, branches. Leaves are large and heart-shaped. Found in marshes, along the banks of ponds and streams, it is not uncommon to see some of the plant growing under water. This provides habitats for small aquatic invertebrates, which draw fish and other species. In addition, after the plant dies, it is decomposed by fungi and bacteria which provide food for aquatic invertebrates. This interesting plant produces white aromatic flowers on top of the hairy stems opposite the top leaf. The flower structure is a spike with lots of small white flowers that form an arch. The seeds form a structure that looks similar to a wrinkled lizard’s tail. This water-loving species has an orange aroma and spreads by rhizomes to form colonies.
Growing Lizard’s Tail Swamp Lily If you have a boggy area in your yard, a small pond, or even a shallow pool of water, that receives part shade, a lizard’s tail plant may be a great option. It is an herbaceous perennial that grows best in USDA plant hardiness zones 4 through 11. Considered a good plant for beginner gardeners, Saururus lizard’s tail is not difficult to plant or care for.
Lizard’s Tail Care This plant requires extremely little attention once planted. It spreads by rhizomes and can be divided by root propagation. No special care is needed to over winter this plant, and it is not susceptible to bugs or disease. As long as it receives plenty of water and partial sun, it will thrive.
