This cool, wet spring was perfect for some early insect and disease problems to appear, namely aphids and powdery mildew. Roses and plants in the rose family, like many of our fruit trees, were rapidly hard hit because of cool, wet spring weather. This will get worse.
Q: Is it too late to prune? We have artificial turf around the tree, but the borders are open for applying fertilizer. Is this good, or should we use fertilizer stakes too?
Cool, rainy weather when pear and apple are in bloom is perfect weather for fireblight disease. Fireblight is a very aggressive and dangerous plant disease that shows up as new infections in about May in Asian pear, European pear such as Bartlett and some apples. It can be a major problem on quince too.
Q: If a fruit tree gets infested with borers in the main trunk and seems likely to die, can I cut off the trunk and allow the tree to grow back from this stump?
Tomato plants that were put in the ground early, before this cold spell, didn’t grow much. This is because of cold soils. Cold air temperatures are bad enough, but when warm-season vegetables like tomato plants have “cold feet,” they struggle to put on any new growth, even with warm air temperatures. If they do get larger because of hot caps or Wall O’ Water plant protectors, it’s not because their roots got larger.
