Tim's Tips: Use warm weather to treat plants


Spraying must be done before the buds begin to swell on the plants. Once tender growth appears on the plants, the oil may damage that new growth. The length of the time frame to perform this spraying depends on what the weather is like during this late part of winter.

As winter slowly drifts away, you have a chance to decrease the number of insects that can damage your plants in the spring. When you get a warm day this month, be sure to apply dormant oil to your deciduous trees and shrubs.

Well, that’s all for this week. I’ll talk to you again next week.
