The disease has gotten a lot stronger as trees have remained stressed since the drought of 2012.

Home Orchards can be very rewarding but take a lot of work, including a very routine schedule of sprays to protect the young developing fruits and leaves against both foliar and fruit diseases and insects that can damage our fruits and eat the leaves. Cedar Apple Rust and Apple scab are the two main diseases and insects like the Apple Maggot and Codling Moth. Most home orchardists with use a combination product containing control material for diseases and insects. Other tasks include doing any needed fruit thinning to allow fewer apples to mature. This also will promote annual flowering and bearing.

Dealing with our spring blooming bulbs the right way an be rewarding with better or more blooms in 2017. Foliage should be leaf intact until the bulb has naturally died down. If you are going to cut some foliage off, limit that to about 1/3 of the levels. Spring is also a great to time to feed your bulbs with mulches of organic matter. We should never tie or braid the leaves together. Bed layout will also help us to hide the fading leaves with plantings in front of the bulbs.
