Plants That Attract Hummingbirds
Q. Which plants will attract hummingbirds to my garden?
A. Hummingbirds are among the many migratory species of birds that pass through the Chicago area in May, as they fly north, and then again in fall, as they fly south. To encourage these birds to visit your garden in both seasons, and possibly even nest there, you should plant the flowers that give them maximum nectar they can convert to energy. Since hummingbirds also eat insects, gardeners are advised not to spray their plants with insecticides.

Apple trees dropping fruit
Q. Why do apple trees drop their fruit early? We have an old apple tree on our property that produces pocked, rotten apples. Is there way we can help the tree produce edible fruit?
A. Some fruit trees will naturally thin themselves by dropping excess fruit prematurely. Often, a period of stress (a long, hot summer with very little rain) will cause a tree to abort its fruit in order to conserve energy. Apple trees require deep watering during drought. Lack of pollination can result in pea-size fruit that falls off prematurely.
