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 […]


Indiana’s State Tree is a Popular Landscape Choice


If you’ve ever had to work on a tree leaf collection, no doubt you included a leaf from Indiana’s state tree. Also known as tulip poplar and yellow poplar, the tuliptree is actually not a poplar at all. It is a member of the magnolia family known botanically as Liriodendron tulipifera. The tuliptree is native to most of the eastern half of the United States and prefers rich, moist, well-drained, loamy soil. It is found throughout […]


Know When to Harvest Your Asparagus


Q. I planted a new asparagus patch last year. I just have a few spears up so far. Do you think the cold weather injured the plants this winter? Is it OK to harvest these spears? Someone told me I shouldn’t harvest at all the first year. A. Asparagus is pretty cold hardy, so if the plants were in good health going into winter, they should be OK. This chilly spring was very slow for […]


May Gardening 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, […]


Tomatoes Are Tops for Summer Crops


Most gardeners would agree that tomatoes are the most popular crop for home growing. But what gardeners can’t agree on is what tomato is considered “the best, since taste is such a personal matter. The diversity of cultivars available makes it easy for anyone to grow tomatoes even if all you have is a pot on the patio. The Burpee Seed Company introduced the first F1 hybrid tomato ‘Big Boy’ in 1949. Since then, plant […]


When to Remove Maple Tree Sucker


Q. I have a maple tree (it is either an ‘October Glory’ or ‘Autumn Blaze’) that has (what I assume to be) a rather large sucker at the bottom. The diameter of the sucker is about 2 inches, and the tree trunk is 7 inches in diameter. I have attached pictures of it from different angles. I would like to know if it is OK to remove it? I’ve read quite a bit about these […]

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 […]

April Garden Calendar


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, […]


Prune Lavender at the Right Time


Q. I have two lavender plants by our front porch. I’m not sure when to trim them. One time in the fall, I pruned them back and it killed them. I replaced those and the plants are now about two years old. Should I trim/prune them in the fall or spring? If so, how much? – C.G., Knox County A. Since lavender is only marginally hardy in our area, I would wait to prune them […]
