Use Caution With Spreading Plants

People often select plants first for their beauty and second for their functionality in the garden. Frequently, we don’t know or don’t consider a plant’s behavior when we’re selecting them. Almost by definition, a species that is an effective ground cover will have a spreading habit. But does that make the species aggressive or invasive? There can be much confusion about the meaning of the terms aggressive and invasive. Some plants, given their optimal habitat,…Read more about Use Caution With Spreading Plants[Read More]

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.

Please see the attached photo — I think it…Read more about Common Winter Injury Symptoms We Saw this Spring[Read More]

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.

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…Read more about Know When to Harvest Your Asparagus[Read More]

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…Read more about When to Remove Maple Tree Sucker[Read More]

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…Read more about Where Have All the Flowers Gone?[Read More]

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…Read more about Blooming out of sequence is cool![Read More]
