Help! Why didn't my fruit trees bloom this year???
Well I am thoroughly mystified and hoping someone can help shed some light on this.
I have 5 fruit trees planted 3 years ago: 3 apples and 2 pears. Last year, I got great blooms from all but one pear (a cheapo plant I bought to be the pollinator for my "good" pear.) I let the most mature apple tree make me about 8 apples last year.
This spring, the only thing that flowered was the cheapo pear.... about 3 weeks ago. I have been waiting and watching and the other 4 trees have NO sign of flower buds and are pretty well leafed out. Last year they all bloomed with my crabapples; the crabapples are past bloom now but still no flowers on the fruit trees.
-In February/march when I pruned, I brought some pruned branches inside to force and THOSE bloomed for me.
-I sprayed with Bonide (organic) dormant oil before bud break in early April.
-We have had a cool/rainy spring.
-I sprayed with organic copper fungicide before 1/2" green, and with sulfur after that. Just 3x so far.
Bartlett pear (was already 2-3 yrs old when planted spring '09; flowered well '09, '10, no fruit.)
Honeycrisp Apple (was already 2-3 yrs old when planted spring '09, flowered well '09, '10, a few apples last year.)
2x Liberty Apple (planted as 1 yr olds spring '09. Flowers, no fruit '10.)
Kieffer Pear- cheapo from Home Depot, bought as pollinator for Bartlett. Did NOT flower last year, but flowered well this year. The only one that flowered. I cannot remember if I sprayed that one with dormant oil or not.
Is it possible that the dormant oil spray made them not flower? Can anyone think why else this might have happened?
