Spring is here!

 Wow….I think Spring is finally here! The chill in the air is gone and the sun feels very warm. Our greenhouse is incredible right now, blooms and leaves everywhere.The first shipment of trees and shrubs came in today.One of the new hydrangeas appeared - Sweet Summer, and a new weigela - Sonic Bloom!  
At this time of year it is important to start watching your trees or shrubs for the first signs of spring. When the plant is still dormant and the leaf buds do not show any sign of green, it is time to use Dormant Oil. It is a spray that you mix yourself, using Horticultural oil and Lime Sulphur. It can be used when the temperature stays above freezing for 24 hours. This product will control insects - scale and aphids, and treats apple scab and powdery mildew.It works by smothering the insect or egg, or poisoning them. It will not harm benifcial insects because of the time of year that it is used. Those insects are just not around. Dormant oil works best on fruit trees, roses, high bush cranberry and snowball viburnum. For roses, you can spray the soil to control powdery mildew and black spot. For all shrubs and trees, start spraying from the top and completely drench all the branches and stems. I have used it at my own house on my snowball bushes with great success.It is important to remember that it may damage Amur maple, cedars and junipers. Colorado Blue Spruce can become discoloured. If you use it after the leaf buds are green, those leaves will either die or the edges will turn black. But for the plants mentioned above it is like a miracle spray.I hope you will consider giving this wonderful product a try.
