10 Effective Ways to Get Rid of Powdery Mildew

Clay and terracotta pots are a great way to add a touch of charm and natural beauty to your garden or indoor plants. However, one pesky problem that can arise with these types of pots is the growth of mold. But don’t worry, here’s How to Get Rid of Mold on Clay and Terracotta Pots.

So like everyone else you have weeds you want to ‘get rid of’ and here is how.

Florida pusley is a low-branching, annual summer weed. Its pretty, white, star-shaped flowers produce an abundance of seeds, and a single plant can quickly turn into an infestation. This weed is extremely drought tolerant and can easily out compete lawns that are not irrigated during extended dry weather conditions.

Unlike other native shrubs and trees that have become the darlings of nationwide advertising campaigns, Florida anise-tree (Illicium floridanum) struggles to achieve widespread interest. This shade-adapted understory shrub can be found growing naturally in shaded, moist to wet areas where it can reach a compact height and width of 6 to 10 ft. The olive-green leaves are 2- to 6-inches long (reminiscent of rhododendron foliage) and release a fragrant anise scent when crushed.

Dr. Matt Cutulle reports, “I saw my first nutsedge plants this year pop up in the plastic mulch of a fellow researcher’s trial last week in Charleston. Soil temperatures in plastic mulch systems are going to be higher, which may lead to earlier sprouting of yellow nutsedge tubers. New tubers begin forming four to six weeks after a new shoot emerges. Individual nutsedge plants may eventually form patches 10 feet or more in diameter, thus it is important to practice field sanitation once an infestation is recognized.”

This is a Florida predatory stink bug (Euthyrhynchus floridanus) feeding on a species of plant-feeding stink bug. The photo shows the predator’s piercing/sucking mouthparts inserted into its prey.

First, a recap of what Impatiens downy mildew (the fungus-like Plasmopara obducens) looks like:Did your impatiens seem to collapse in 2012? Early signs of infection may have been leaves that looked yellowish, as if the plant needed feeding, or foliage that curled under or seemed to wilt. Sometimes, a white material (the downy mildew) is visible on the undersides of leaves. Eventually, plants may defoliate, drop their flowers, and basically collapse. The fungus loves moist conditions and cool nights in particular. Particularly disturbing: symptoms happened earlier last year than before—as early as June.The disease, which attacks Impatiens walleriana (the species our

In Part 1 (a transcript of which is at this link) we talked with a caller curious about the wonderful tree called Stewartia and how to make it happy—plus Ken recommended other garden-sized, multi-season trees to consider adding to your landscape, including dogwoods, redbuds, and tree lilacs.Ken, of Ken Druse dot com, is a longtime garden writer, author and photographer and all-around great gardener—and great friend.

AllImpatiens walleriana types are potentially affected. That’s the species that the common garden impatiens is bred from, as are the double-flowered types and miniatures and the Fusion series I like so much (that’s variegated Fusion Peach Frost, above). Other impatiens species may likewise be susceptible–even the native jewelweed, Impatiens capensis.The updated Impatiens Downy Mildew factsheet from Cornell Cooperative Extension explains that early signs of infection may have been leaves that looked yellowish, as if the plant needed feeding, or foliage that curled under or seemed to wilt. Sometimes, you can see a white material (the fungus) on the undersides of leaves. Eventually, plants may defoliate, drop their flowers, and basically collapse. The American Floral Endowment website has detailed photos of symptomatic plants, and other links (most geared to growers) about this threat to a favorite bedding plant.Categoriesannuals & perennials compo

If this sounds familiar, maybe you thought it was “your fault.” Chances are it was basil downy mildew, a devastating disease that in 2014 was reported to thwart backyard and commercial growers alike in at least 35 states plus the District of Columbia—up from 20 plus D.C. in 2013.For farmers, a once-easy, profitable cash crop is challenged; for gardeners, a beloved ingredient elusive.
