This Week In the Garden
Spraying Dormant Oil

This week in the garden retired UT extension agent Mike Dennison demonstrates how to apply dormant oil to a crape myrtle tree. This procedure is also applicable to other ornamentals and shrubs. Spray to the point of runoff. Dormant oil will tend to separate from the water in the sprayer tank so make sure you shake it regularly to keep it in suspension.  Do not spray less than 48 hours before a hard freeze. The water in the spray may freeze injuring the plant. As always read and follow label instructions for mixing and applying dormant oil.
