Much Ado About Leaves

Ah, the beauty of Mother Nature’s palette coming to life in the fall color of our forest and landscape plants. For some, this marvel is overshadowed by the chores of raking and disposing of fall leaves. What’s needed here is an attitude adjustment! Autumn leaves don’t have to become trash. On the contrary, they easily can be turned into valuable soil-enhancing organic matter. For many urban dwellers, who already have their yard waste picked up […]

September “In The Grow”

Q. Although I am aware of the need to cut back or pinch mums until about the Fourth of July, I need your advice about other flowers, namely daisies, black-eyed Susans, impatiens and petunias. Should all of these be pinched, too, and if so, when? For some time now, I have noticed so many daisies and black-eyed Susans in beautiful clumps standing so stately. As soon as mine are blooming nicely, they begin to droop […]

In a Pinch!

Summer is not the preferred time to prune landscape trees and shrubs, but it is a great time to prune many annual flowers. Plants such as petunias, impatiens, zinnias and marigolds tend to get leggy and produce fewer blooms by mid summer. Pinching these plants back about halfway will encourage more branching and, in turn, more flowers. The plants may look a bit raggedy initially after being cut back, but with a little water and […]

August “In The Grow”

Please tell me what I can do with squirrels? I plant flowers and tulip bulbs and other bulbs.

Can you help me solve the problem? – Mrs. John Bielefeldt, Chicago Heights, Ill. A. Exclusion is tricky but effective. Fencing or hardware cloth around the […]

July “In The Grow”

Q: Enclosed are two pictures&emdash;one of my seemingly healthy primrose, the second one taken a few weeks later&emdash;not so healthy. Could you please diagnose this problem and suggest a cure or possible preventive treatment for later use? I enjoy your column very much. Thank you for helping. – Pat Ritter, Bloomfield, Ind. A: This is a direct result of our extremely wet weather this year. Oenothera species have many different names, including Ozark Sundrop or […]

Coping with Storm-damaged Trees

Homeowners assessing tree damage caused by recent storms will want to make a few important decisions soon. Small trees with minor damage can probably be taken care of by the homeowner, but large, mature trees likely will need the help of a professional tree service. It can be hard to decide whether trees with severe damage should be completely removed. Homeowners often are reluctant to cut down a tree, either because of sentimental attachment or […]

Blossom-end Rot of Tomatoes Likely This Season

You’re an eager home gardener who has lovingly nurtured a tomato patch from seed to fruit. But alas, just as your mouth waters for the first ripening gems, a black, leathery spot appears at the base of the fruit. Blossom end-rot is thankfully a frustrating disorder and not a disease of the fruit. The black scar tissue is caused by a deficiency of calcium in the developing fruit, usually brought on by extreme fluctuations in […]
