Powdery Mildew

Powdery mildew is an obligate parasite.  Huh?  In short, powdery mildew doesn’t want to kill your plants – but it sometimes happens, by accident of course.  We most often see this disease on plants outdoors where there is poor air circulation.  You probably have seen peony bushes around town or even your own that ended…

Fall Garden Clean Up

When cleaning up the fall garden, it’s hard to know what should be cleared away and what should stay.  Gurus of tidiness opt for removing everything now in order to start with a clean slate in the spring.  But is there such a thing as too much tidiness?  It turns out that, yes indeed, that…

October Musings on the Vegetable Garden

Recently my friend Mary Anna returned from out of town to find her vegetable garden had been visited and the butternut squash eaten.  Teeth marks on the squash remnants indicated that one or more squirrels were the culprits.  Butternut squash wouldn’t necessarily be a squirrel’s first choice but as the growing season slows, all animals…

The Picnic Beetle

Picnic beetles are small black insects with yellowish spots on their wing covers. This nuisance insect feeds on over-ripe and decaying fruits and vegetables. Its common name comes from its annoying habit of showing up in your potato salad at outdoor events. While it can damage fruits and vegetables, picnic beetles take advantage of over-ripe…

Growing Food Indoors? Sure!

As we celebrate National Indoor Plant Week, my question turns to can we grow food indoors?  The answer is emphatically, yes! Perhaps the simplest option for indoor food production would be to grow some container plants that would work well.  Crops like lettuce, arugula, and some of the other leafy greens have lower light requirements…

Squash Vine Borer

Nothing is more frustrating than seeing the almost-ready-to-produce zucchini plant collapse.  If the base of the plant is mushy and has holes, the most likely reason is the squash vine borer. The squash vine borer adult is a ½ inch long moth that doesn’t look or act like a moth. It has an orange abdomen…

Blossom End Rot of Vegetables

So your zucchini has these leathery brown areas on their blossom end?  What is this and what can a gardener do about it? Blossom end rot is confusing because it looks like it’s caused by a fungus.  It isn’t a fungus.  Instead it is a lack of calcium that is the cause.  Before you rush…

Japanese Beetles—They’re Colorful, They’re Hungry and They’re Here

The most important thing to understand about Japanese beetles is their feeding doesn’t kill trees, shrubs and flowers.  Granted, it isn’t fun to see the lacy leaves they’ve created, but pesticide management options require thought and planning before you set out for revenge. Systemic insecticides, for instance those containing the active ingredient imidacloprid, are taken…

Grasshoppers

They are cute.  They are little.  So what is the big deal if there are lots of grasshoppers?  These seemingly innocuous little guys and gals can be quite harmful to our landscape plants and vegetable gardens.  As grasshoppers grow, their appetites become larger, making the damage they do even more severe. Floating row covers and…

Herbicide Damage to Vegetable Plants

Twisting, curling, and cupping of leaves are often symptomatic of herbicide damage on vegetable plants. The culprits that most readily cause this type of damage include 2,4-D (used to kill broadleaf weeds in lawns and pastures), dicamba (lawn and crop broadleaf weeds) and picloram (pasture broadleaf weeds). These herbicides are plant growth regulators, killing weeds…
