Renewal pruning has immediate, delayed rewards


Q:  I have 2 Forsythias, 2 Spireas, a Ninebark and a variegated Dogwood that appear to be half dead. My thought is to cut them down now to regrow so they’ll have all summer to do this. What are your thoughts? Last year all of these bushes were lush and full. A: Although it could be done now, late winter is the ideal time of year to completely cut the shrubs to the ground. But […]


May Garden Calendar


HOME (Indoor plants and activities) Many indoor plants can be moved to shady locations outdoors but only after the danger of frost has passed. Plants will dry out more often outdoors, so keep a close eye on soil moisture. Sinking the pots in soil will help slow down moisture loss. Now is a good time to take cuttings of houseplants to increase a collection or share with friends. Root cuttings in media, such as vermiculite, […]


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. […]


November Gardening Calendar


HOME (Indoor plants and activities) Check houseplant leaves for brown, dry edges, which indicates too little relative humidity in the house. Increase humidity by running a humidifier, grouping plants or using pebble trays. Extend the lives of holiday plants such as poinsettias and Christmas cactus by placing them in a cool, brightly lit area that is free from warm or cold drafts. Houseplants may not receive adequate light because days are short and gloomy. Move […]


Pussy willow shrubs can thrive in well-drained soil


Q: I am writing about a pussy willow tree I planted in my backyard in early August 2018. I have wanted one for some time and found one on sale at a discount department store. It didn’t have much info on what it takes to grow by ponds or lakes. So, if you could give me any information, it would be appreciated. A: A number of willow shrub species are commonly called pussy willows, so […]


Eastern Red Cedars Volunteer Way Too Often


Q. I am wondering what you might know about the small “red cedar trees” that seem to be invading fencerows and highways, especially U.S. 31 north of Kokomo. I think a column from you would be worthwhile, since I can`t seem to get my neighbors to control the “pretty little trees,” which are much like Canadian thistle and kudzu. — E.W., Kokomo A. The eastern red cedar is a juniper, rather than a true cedar. Known […]


Common Winter Injury Symptoms We Saw this Spring


Q. I have a yucca tree that is 5-6 years old. What was a small plant has become a mature tree. I transplanted my yucca to a larger pot last summer. There was a significant explosion in growth. If you look at the picture you can see the growth. Unfortunately, it suffered through this past winter indoors. Much of the new growth witnessed last year is gone. Please see the attached photo — I think it […]

Where Have All the Flowers Gone?


Winter 2017-18 was pretty harsh compared to most years. Much of central and northern Indiana experienced 13 or more days well below zero, while southern Indiana had four to five days just a few degrees below zero. In addition, gusty winds further injured plants by desiccating buds and twigs. The consequences remain to be seen. While some spring flowering trees and shrubs may perform admirably this season, some species will have few or no blooms […]

Mystery plants identified


Q. I have some leaves from a tree I would like to identify. It is roughly 8 to 12 inches in diameter and fairly tall. The leaves are alternating with lengths of 1.5 to 2 inches long. The leaf stalks are all really short compared to the leaf length. Can you identify? – M.R., Brookville, Indiana A. This appears to be Ulmus parvifolia – common name Chinese elm or lacebark elm. This species is quite […]

Blooming out of sequence is cool!


What is that crabapple doing reblooming in October and November? Actually, it might be more correct to think of it as jumping the gun on next spring rather than reblooming. Although it happens to some extent many years, there seem to be more reports thas usual of landscape plants blooming out of sequence this fall. Rhododendrons, crabapples, and saucer magnolias are the most commonly reported species blooming this fall. Spring-blooming woody plants initiate flower buds […]
