Plants are also sold as container material which can be planted almost anytime throughout the growing season with very little stress. If you have kept the foliage growing, you can plant hyacinth, crocus, narcissus and other forced bulbs outdoors as soon as the outdoor temperature is much like the climate inside your home. Bulbs that have been forced generally don't do well outdoors, however. It's wise not to expect them to come up and flower next spring. It would be a great idea.
Crabapples can act as a source for scab infection and fruit insects.
Old, neglected fruit trees in the neighborhood can also be a problem, but there's not much you can do about your neighbor's trees unless you're willing to spray them along with your own. This depends on the location of the trees, the local climate and the temperature. At minus 13 to minus 16 degrees F., the flower buds of most peach varieties will be killed and the trees will bear no fruit this year. At lower temperatures, the trees or part of the tree may be killed. You can determine the amount of flower bud injury that occurred for your particular tree.
