Dormant season plant healthcare treatments

With the leaves down and your harvested fruit all canned, pressed or fed to local wildlife, its time to consider wintertime care of your trees and plants. Pruning can be done anytime between leaf fall and the first signs of budding in late winter. Early winter is probably best, so you can enjoy the fruits of your labor for longer. Remove diseased and dead limbs first. Crowded and crossed-over limbs next. Remove all lingering fruit to reduce overwintering insect eggs and fungus spores.

Our persistent wet winter weather here in the PNW gives rise to many fungal and bacterial diseases that attack a host of fruit and ornamental plantings. Overwintering insects take advantage of mild winter temperatures to stay viable and ready to feed in spring. Preventive treatments with horticultural oil and elemental copper is a great way to get ahead of some of the insects and diseases before they become active. Copper is especially useful against bacterial canker diseases on a host of trees and plants.
Our treatment targets include:
Fruit and flowering trees (Canker, apple scab, brown rot, anthracnose, eggs of aphid, apple maggot, tent caterpillar, mites, scale and more)
Evergreens (spider mites, adelgids, needle blights, weevils, tussock moth, pine sawfly, cankers and more)
woody plants and perennials (lace bugs, aphids, sawfly larvae, lilac blight, eastern filbert blight and more)
A dormant treatment is a staple in any insect and disease protocol for nurseries and orchardists. It is included in our six-time-a-year YardGuard program. Both our horticultural oil and copper products are OMRI approved for organic certification. Your landscape deserves the benefits this treatment can provide.
