September “In The Grow”

Q. I have a weed in my garden that I can’t get rid of. It lies close to the ground and spreads. It has small green leaves that are thick and feel like rubber. Is there anything you can tell me to help me get rid of it? Thank you. – Sheila Denton, via e-mail A. It could be a number of weeds but sounds most like purslane. Purslane thrives in hot, dry weather. The […]

Pin Oak Looking Yellow?

Pin oak trees can be a beautiful asset to the landscape. Their pyramidal form, pendulous lower branches and reddish or bronze fall color are striking. Unfortunately, most pin oaks planted in the Midwest are plagued by a yellowing of the leaves known as chlorosis. Other landscape plants are also susceptible to chlorosis, including rhododendrons, river birch, holly and sweet gum. Chlorosis gets its name from the lack of chlorophyll, the pigment responsible for healthy plants’ […]

August “In The Grow”

Q. I have some yucca that has turned yellow and has little black bugs on it. What can I do? It starts out green, then turns in the middle of summer. – Grace Griffin, Memphis, Ind. A. The yucca plant bug is a small blue-black bug with a reddish head. The adults and nymphs hurt the leaves by sucking the plant sap, causing the leaves to turn yellow and stippled. Treat with insecticidal soap, horticultural […]

Harvest Winter Squash This Summer

This summer’s heat wave is bringing the vegetable garden to maturity a bit earlier than usual in some areas. So many of our typical fall-harvested items may be ready sooner than you’re expecting.   Winter squash is so named because it is harvested in the mature stage, when flavor is rich and the rind is tough, making it suitable for winter storage. Summer squash is harvested in the immature stage, when the rind is still […]

It’s a ‘Berry’ Good Time To Clean Up the Strawberry Patch

The strawberry harvest may be over, but that doesn’t mean it’s time to forget the plants. Post-harvest care is an important part of keeping your patch healthy and productive. With yearly renovation, strawberry plants can remain productive for 10 years or longer.   Ideally, you should renovate the strawberry bed immediately following the last harvest. The work can still be done now, though it would be best to finish up before the end of July. […]

Ornamental Grasses Add Beauty and Texture

Although many gardeners think of grass as that plant that has to mowed every week, there are many species of grass that rival any garden flower for beauty and grace. Many ornamental grasses have attractive form, foliage, flowers and color-or even all of the above. Grasses can be used as ground covers (that do not have to be mowed), specimen plants, hedges, perennial borders, naturalized plantings and even rock garden plants. Perennial grasses that are […]

July “In The Grow”

Q. We have a big problem with bagworms. Last year they destroyed two decorative pine trees in our landscaping and they love our plum trees also. I cannot begin to count how many of their cocoons are left in our landscaping. What can I put on my trees and other plants to keep them from making their home too close to mine? Also, what time of the year should I take care of this problem?- […]

Cold Weather Affects Vegetable Plants

It has been quite a year for Indiana gardeners already, and it has only just begun! We’ve had just about the whole range of possible weather from drought to flood and late frost to blazing heat. Recent cold weather has frustrated many vegetable gardeners. Plants such as tomatoes, peppers, beans, squash, cucumbers and melons must be successfully pollinated in order to produce their fruit. Extreme temperatures, below 55 F or above 90 F, will dramatically […]

June “In The Grow”

Q. Each year, my vine crops are affected by the larva of the Squash Vine Borer. I have tried powder pesticides, but find that I have to apply them almost daily due to early dew and frequent spring rains. I would like to cover the plants with a fabric instead. Can you tell me what type of fabric to use, what weeks out of the year to apply it and when it is safe to […]

May “In The Grow”

Q. I purchased some tulip and iris bulbs on clearance in late November and never got to plant them in the fall. They were in an unheated barn over the winter, and I planted them March 1. Do you think any growth will appear this year or, if not, next year, or are the bulbs dead? – Linda M. Laud A. When we gardeners get to the garden center, we become eternal optimists. We’re just […]
