|Plant of the Month|
Rhododendron and Azalea
Rhododendron flower cluster
The genus Rhododendron
is a large and diverse group that includes not only the "rhodies" but also Azaleas.
These shrubs are some of the most popular of all the shade tolerant flowering shrubs. Their huge clusters of blooms create a dazzling display during the spring and into early summer. Beautiful Diversity
There is great diversity within this group with many different growth forms ranging from dwarf varieties that grow only a foot tall to the towering native giants that can reach up to 20 feet in the wild. Many varieties have beautiful deep green evergreen foliage and some are deciduous. Most require little pruning as they have a very attractive natural layered growth form. They are like the "perfect" garden shrub when planted in the right location!
|Beautiful azalea flowers|
Rhododendrons and azaleas are typically grown for their beautiful displays of flowers and they have been widely hybridized over the years to create an even greater diversity in flower color, foliage, and growth form.
Rhododendrons thrive in moist, well-drained, acidic soil that is high in organic matter. The optimal pH for these shrubs is between 4.5 and 6.0. If your soil tests higher than 6.0, it is advisable to add a soil acidifier to bring the pH down to within the recommended range. See the section below for our recommendations for lowering the soil pH. Wet feet are deadly
for these plants! Be sure to plant them in an area that is well-drained
as they are prone to root rot and other fungal diseases when the soil is constantly soggy.
In general, Rhodies and azaleas prefer bright dappled shade but there are some varieties that can tolerate full sun and some that will grow and bloom well in dense woodland shade. They will not tolerate hot, dry, or windy conditions. Plant them in a location that is sheltered from high winds that can desiccate the foliage and cause damage especially during the winter.
Fertilize these plants with a slow-release organic fertilizer for acid-loving plants in the fall and again in the late winter or early spring. Espoma Holly-tone is a great choice for rhododendrons.

Pruning is generally not necessary except perhaps for light pruning
to remove wayward branches and spent blooms or to maintain the desired shape or size. This light pruning should be done right after they finish blooming. To remove the spent flowers, carefully cut or pinch them off without damaging the small leaf buds that have formed just behind them. If your Rhododendrons have gotten a bit too tall, bring them back down to size by cutting the stems back to just above a whorl of leaves. Be sure to prune carefully
so that you maintain the natural layered look of these beautiful shrubs.
Severe pruning of very overgrown rhododendrons and azaleas is a great way to bring them down in size if they have grown too large for your space. Because these plants have dormant buds on the interior bare wood close to the main stem, they can be pruned heavily until just bare branches remain or you can even cut them back to one to three feet above the ground. This type of hard pruning should be done in late winter or early spring while the plants are still dormant. Severe pruning like this is not always 100% successful but a very high percentage come back with beautiful new growth!
Acidifying your soil

It is a good idea to have your soil pH tested before planting your rhododendrons or azaleas. Providing the plants with the best growing conditions will help ensure their success in the garden. Aluminum sulfate
Sulfur in some form is the most effective way to acidify your soil. Straight chemical or elemental sulfur is commonly used but it is slow to affect a change in soil pH.
causes a more rapid decrease in soil pH but the aluminum can become toxic to plants if it is overused.Iron sulfate
adds iron to the soil as well as lowering pH.Organic amendments
for lowering soil pH include peat moss, pine straw, or sphagnum moss. Though these amendments are beneficial to soil structure, they must be added in large quantities in order to affect pH and then the pH change is very slow.
If you have the right conditions, these beautiful shrubs are a "must have" in the garden!

Tip of the Month
| Controlling Lawn Weeds!|
|Persian speedwell is a common broadleaf lawn weed.|
There are many types of broadleaf weeds which are commonly found in home lawns. These weeds often thrive in lawns that are growing in poor soil or where incorrect lawn maintenance is followed. The best defense against lawn weeds is to maintain a healthy, vigorous lawn by keeping your lawn adequately fertilized, properly watered, and mowed at the correct height. Sometimes, however, weeds persist in spite of good maintenance. For small lawns or where there are only a few weeds popping up, hand pulling as weeds appear can be good exercise and often provides good results. The use of herbicides to control weeds is more practical for large areas, difficult-to-pull weeds with deeper root systems, or small patches of persistent weeds.
Below are a few common lawn weeds and some suggestions on their control.
|Dollarweed thrives in moist, |
Dollarweed or pennywort as it is sometimes called is a perennial broadleaf weed which is common in warm season grasses. It looks like a small lily pad and will thrive in weak and infertile soils where the ground is wet. Because dollarweed reproduces several different ways (seeds, tubers and rhizomes), controlling this weed is difficult, especially when the weed has been left untreated for a season.
- If Dollarweed is a problem in your lawn be sure to reduce your irrigation frequency and duration.
- Chemical controls for Dollarweed vary depending on where the weed is a problem. In lawns, the weed can be controlled by using a high quality selective lawn weed control such as Bonide Weed Beater Ultra or Bonide Weed Beater Plus. Both products list Dollarweed on the label and offer full control in a variety of lawn types without harming the grass.
- Dollarweed can be controlled in planting beds by applying glyphosate to the weeds being careful not to apply to desirable plants. Glyphosate is a non-selective herbicide and is the active ingredient in Bonide KleenUp Grass and Weed Killer.
- Because of its extensive root system and the various ways that Dollarweed reproduces, multiple applications of weed control in lawns and in beds may be necessary.
- Be sure to read and follow the label directions carefully and pay attention to the temperature guidelines if applying in the summer.
|Ground Ivy; Leslie J. Mehrhoff, University of Connecticut, Bugwood.org|
Whether you know it as Ground Ivy, Creeping Charlie, or Creeping Jenny, this annual weed can be very difficult to control in lawn areas. The difficulty comes from the fact that the plant spreads using both above ground stems called stolons and below ground shoots called rhizomes. This combination of root and stem systems means that, in order to control this weed, you not only have to choose the right product, but your timing has to be good as well.
- Chemical controls currently available include:
- Best control is achieved with 3 separate applications of products, once in spring just after the plant flowers, one following up 3-4 weeks later and a final fall application to kill any residual weeds and to prevent any re-growth in the spring.
- Cultural practices including mowing to a height of at least 3", applying a fall fertilizer, and overseeding with a quality grass seed can also help control this challenging weed.
Nutsedge or nutgrass:Yellow nutsedge is a perennial plant that reproduces primarily by small underground tubers called nutlets. It can also spread by rhizomes (below ground stems). Farmers have difficulty controlling this weed, and as farm land is converted to home sites, yellow nutsedge plants and nutlets, are often found in the soil of lawns.
Nutsedge is most easily identified by the triangular shape of the stem ("sedges have edges"). If you roll the stem of the plant in your fingers, you should be able to feel the triangular shape. The leaves are light green to yellowish in color and are very slick or waxy to the touch. Yellow nutsedge grows most actively during the hot months of summer. Often the leaves of yellow nutsedge will grow 2 to 4 inches above the turf canopy. During spring and fall, when temperatures are cooler and growth is slower, yellow nutsedge is not as easily noticed.
Nutsedge thrives in moist soils. One of the best ways to control it is to improve the drainage so that the area dries out. This will make the conditions less favorable for the
and allow your turfgrass to take over and fill in.
Herbicides may be required
when large patches of nutsedge are present in the turf area.
- For homeowners, herbicides like Bonide Weed Beater Complete containing Prodiamine and Sulfentrazone provide good control when applied according to directions. Bonide Weed Beater Complete offers an effective control for all varieties of nut grass in your lawn.
When things get really bad ...When weed infestation becomes serious (greater than 40%) and the turf condition is poor, consider a total renovation of your lawn. Be sure to replant with a turfgrass mixture that is well suited for your particular site.
