Pest Control

Leaf and Fruit Disease Control

Our rainy, high humidity spring weather is ideal for the development of a number of leaf and fruit diseases. Most of these diseases can be reduced by cleaning up last year’s old leaves. The disease spores for this year’s infections are carried on last year’s old leaves. There are a number of fungicides which will [...]

Dormant lnsect Control

Many insects overwinter as eggs or pupae on the bark of dormant branches. Dormant Oil (a natural organic pesticide) will kill most overwintering insects including scale insects which are hard to control with other pesticides. If you have had insect problems with particular plants during the growing season, those insects may be overwintering on those [...]

Safe Organic Pest Control

There are two wonderful organic pesticides which are completely safe to use on food crops and around children, pets and wildlife.
Spinosad is a compound derived from a bacterial species originally found on sugar cane. It is an organic pesticide with uses including cat fleas as well as for agricultural food crops.
It controls a wide range [...]

Carpenter Ants

            Those large black ants roaming around your yard are probably carpenter ants. Carpenter ants do not eat wood, but the will excavate it for nesting and occasionally can cause structural damage. They will also nest in insulation. In most instances they are mostly nuisances. Many home infestations are satellite colonies from a nearby stump [...]

Weed in Bites

I like to weed early in the morning. It is cool, and I can listen to the birds singing their morning songs. By weeding 10 to 30 minutes almost every morning I can keep ahead of the weeds. If you have a regular job, try setting your alarm 20 or 30 minutes earlier. There is [...]

Controlling Blackberries

The wild Himalayan blackberry is one of the most difficult weedy plants to control in the Pacific Northwest. Blackberry vines are so difficult to control because established plants spread by nodes – or small underground buds – that grow off established blackberry vine roots. No matter how much of the plant you remove, you’ll miss [...]

Rose Disease and Insect Control

Roses need repeated applications of fungicides and insecticides to protect them from diseases and insects through the growing season. The three main rose diseases prevelant in the Pacific Northwest are black spot, mildew and rust. All three diseases can be controlled by systemic fungicides  such as Propiconazole, Myclobutanil and Tebuconazole. Propiconazole is available in Fertilome [...]

Leaf Diseases on Flowering Cherry, Dogwood, Photinia and Peaches

Leaves of these trees and shrubs should be protected with a fungicide application as they begin to grow in late March and April. Most effective are the systemic fungicides  such as Propiconazole, Myclobutanil and Tebuconazole. Propiconazole is available in Fertilome Systemic Fungicide. Myclobutanil is in Spectracide Immunex Fungicide. Tebuconazole is in Bayer All-in-One Rose and [...]

Moss Control

Moss loves shade and wet areas. Moss is easily controlled. Moss Control products for plants contain a natural iron compound which not only kills moss but turns grass and leaves dark green. Iron compounds can stain concrete a rust color. So if some is spilled on concrete, brush it off before it becomes wet. (I have [...]

Organic Insecticides

 Many gardeners like to control insects organically or naturally as much as possible to avoid dangers in handling pesticides and residues on plants. An increasing number of organic pesticides are becoming available for use.
 Bacillus thuringensis (often referred to as B.T.) is a bacteria which causes disease in insects, especially caterpillars, within two days after they [...]
