Today I sprayed my apple (dwarf Fugi) and two pear trees (a Keiffer and a Bartlett) with a dormant oil spray. I also gave one of my grapes (a Cabernet Sauvignon) a spray too. The buds are nicely swollen and I am pleased to see that there are a few flowers buds ready to pop on the pears this year – finally. (I have been pruning them wrong and removing the buds for 2 years.) It was a warm sunny day – up to about 50*F, and bugs just starting to get active. I think this is the perfect timing for the oil spray. I diluted it to 4 Tbs in a 1 qt spray bottle, then soaked all the branches well.
