The plants in your landscape are still dormant, and we know that winter is still in full effect, but now is the perfect time to start your planning for the upcoming growing season. Especially if you want to get a jump on battling out pest problems that can attack your fruit trees during the growing season.
For controlling various diseases and insects that affect fruit, there are many dormant sprays that can be used. In order to control scale insects, a dormant oil spray is always best. So if you have experienced issues with scale in the past, now is the time to spray. It is best to spray before March 1, especially with peaches and nectarines. If you are growing apples, the application can be delayed up until the green tip stage, or when growth is just starting.
You also want to make sure the temperature is at least 40 degrees so the spray will dry before freezing. Plant injury is possible if the spray does freeze before it dries.
