Q. I read your article on fire blight. We have a bad case of fire blight on one of our pear trees. You spoke of doing a pruning of the diseased parts, and we were wondering when would be the best time to do the pruning–spring or fall? — Linda Am Rhein, Scipio, Ind. A. Fire blight-infected limbs and branches should be pruned during late winter when there is much less chance of spreading fire-blight bacteria on […]
Evergreens require a bit different manner of pruning than other landscape plants. Although a plant is not likely to die from improper pruning, it is important to note that most evergreens cannot replace lost growth the way that deciduous plants can. So while other landscape plants might be able to outgrow an errant pruning job, evergreens can suffer permanent disfigurement. Individual plants should be assessed for pruning needs. Evergreens that have been sheared into formal […]
Each year, the National Garden Bureau selects a flower to promote, and this year the annual garden flower known as vinca is the star of the show! Vinca is a popular annual bedding plant in the Midwest with loads of single-flower blooms in shades of red, pink and white. More accurately identified botanically as Catharanthus, there is much confusion regarding the name of this plant. Catharanthus is the sun-loving, summer-flowering plant that is grown as […]

Q. I have a corn plant that my sister game me. She lives in North Carolina, and I live in Indiana. I brought it home and it was beautiful. I looked it up in a garden book and the only information on it was to keep it watered–1 inch–when it feels dry. It is not doing well at all. Two bunches of the leaves fell off at the trunk. Each time I water, more leaves turn […]
Many landscape plants will require pruning at some stage of their life. Plants may need to be pruned to reduce or maintain plant size or to remove dead or damaged material. Pruning is also used to reduce overcrowding and rejuvenate older, overgrown plants to produce more flowering, fruiting and/or leaf canopy. Using the right tool for the job will help protect both plant and human. Both the size of the material being cut and its […]
Instead of throwing out that pineapple top, turn it into a houseplant! Carrot tops and avocado pits can also be salvaged from the garbage pail to the ranks of houseplants. To grow a pineapple, cut off the leafy top, leaving about a one-fourth inch of the fruit attached. Scoop out the pulp and let the top air dry for a few days. Then, press the top into a pot or pan of moistened rooting media, […]
Q. Each year, including this past one, some of the new growth on my pear trees turns black and wilts. This year is the worst ever. What causes this and what can I do about it? – Ann Hunt, West Lafayette, Ind. A. Fireblight causes young twigs and flower blossoms to wilt, blacken and die. Often the tips of blighted twigs become crooked, resembling a shepherd’s staff. Fireblight affects apples, pears and certain ornamentals, including crab apples, […]

There appears to be much confusion about these unique tropical cacti regarding care, maintenance and, especially, on how to get them to re-bloom. The following tips address the most frequently asked questions. We typically think of cacti as being heat tolerant, but Christmas cacti will keep their blossoms longer in cooler temperatures. Keep the plant […]
The recent warm spell has many a gardener wondering what to do about bulbs–and perhaps a few other plants poking their foliage through the soil. This is the time of year when we normally expect temperatures to be cold enough to signal the hardening-off period to plants. And for a brief while, it was cold enough to start that process. The longer the warm spell, however, the more plants have begun to sprout new growth […]
