Ornamental Pear Fallout


Q: I’ve attached pictures of the only tree we have on our property. Because it is our only tree, I am deeply concerned with the possibilities of irreparable damage to it. As you can see, one of the branches broke off during a November windstorm. Unfortunately, that left a bare gap on the trunk. Please let me know how to treat this damaged area so no further damage is done to it and tell me […]

Yard & Garden Calendar – April


HOME (Indoor plants and activities) Start seeds of warm-season plants (including tomatoes, peppers, eggplant, marigolds, zinnias, and petunias) indoors for transplanting later to the garden. Harden off transplants started earlier in spring before planting outdoors. Gradually expose the young plants to outdoor conditions of wind, brighter sunlight, and lower moisture. Apply fertilizer to houseplants according to label directions as days grow brighter and longer and new growth begins. Foliage plants require relatively high-nitrogen fertilizer, while […]


Rhubarb is prone to bolting. Here’s what to do


We humans can be so difficult to please. When plants flower when we want them to, we call it blooming. But when plants flower when we don’t want them to, we call it bolting. Flowering is an undesirable trait when growing rhubarb; therefore, bolting describes the event. Gardeners frequently ask why their rhubarb is bolting. Well, if you think of it from the plant’s perspective, it is just a part of the plant’s natural life […]


Early spring pruning will tame this hydrangea


Q: I have a hydrangea that is overgrown. It’s falling over and is too tall and wide. I would like it not to block the window. But I don’t know how/when/how much to prune to a smaller size. — T.B., Morgan County A: Pruning time and technique depends on the particular species of hydrangea. Yours appears to be the panicle hydrangea, Hydrangea paniculata. Panicle hydrangea blooms on new wood, meaning the flower buds are produced on new […]


March Gardening Calendar


HOME (Indoor plants and activities) Begin fertilizing houseplants as new growth appears. Remove spent leaves and flowers to improve appearance and encourage more blooms. Start garden seeds indoors for transplanting outdoors later in spring. Check stored bulbs and produce for decay; discard damaged items. Prune, repot, and clean houseplants as needed. YARD (Lawns, woody ornamentals, and fruits) Prune trees and shrubs (except those that bloom early in spring) while plants are still dormant. If you […]


Please Don’t Top Your Trees


Topping a tree is an all-too-common practice among homeowners, particularly when their trees become too tall and pose a possible threat to the house or overhead power lines. Some have the trees topped because they believe, or are led to believe, that topping is a good pruning practice. Some situations obviously require the removal of large limbs for the sake of safety. But topping is a drastic step that ultimately endangers the tree’s life. Removing […]


Timing of hydrangea pruning varies by species


Q: Attached is a photo of our current hydrangea plant in front of our house. Should I cut it back now or leave it alone until spring? Or do you think it’s a lost plant? – R.G., Henry County, Indiana A: A number of hydrangea species are grown in Indiana. The proper time of pruning depends on the species. Your photo appears to be Hydrangea quercifolia, more commonly known as oakleaf hydrangea, one of our […]


Snow Is Good for Gardens


Though your aching back may not agree, recent heavy snows actually will be good for your garden and landscape. Snow provides moisture as well as protection from cold and wind. Snow is an excellent insulator against low temperatures and excessive winds. The extent of protection depends on the depth of snow. In addition, the soil gives off some heat so that the temperature at the soil surface can be much warmer than the air temperature. […]


Pretty ground cover? Probably a weed


Q: I’m having an argument with my wife about a plant in our yard, and we hope you can help arbitrate. I’ve sent a photo of a plant that we found growing near some shrubs. Neither of us remember planting it. My wife thinks it’s pretty ground cover and that we should let it stay. I think it’s a weed and that we should get it out of there before it takes over the whole […]


Pollinators are abuzz for the 2019 Perennial of the Year


By selecting Stachys officinalis ‘Hummelo’ as its 2019 Perennial Plant of the Year, the Perennial Plant Association once again continued its focus on pollinator-friendly plants. ‘Hummelo’ is a compact, clump-forming perennial, reaching 1.5 to 2 feet tall and wide. Over time, the plants will form a dense mat, spreading slowly from creeping underground stems. Showy magenta flower spikes rise well above the foliage in midsummer and are quite attractive to butterflies and other pollinators. Plants are hardy in […]
