Mike explains how to care for seedlings out of season, why you should be wary of old fruit orchards, how to build a stinkbug trap, the benefits of soil solarization, and how to get rid of Japanese stilt grass safely.
Question of the Week:
“HELP! Our lawn is being invaded by Japanese Stiltgrass! We’ve been told that herbicides are the best way to get rid of it, but we don’t want to kill everything else in the yard. We’ve tried pulling it up by hand but can’t seem to get it all. What should we do?” — Jason and Tina in Patterson, New York

Highlights from show for September 28, 2013:
Growing seedlings out of season
Susan from Beaver Creek, Ohio is fostering seedlings from a watermelon that her 9 year old son planted in an ice cream cup with soil from a flower bed outside. Now that the seedlings are growing in her basement with a light she wants to know what to do next. Mike explains they are relatively easy to grow if they are started in the Spring instead of the Fall. Susan says she wants to take this to it’s natural conclusion so Mike suggests getting a good plastic pot with drainage holes and loose light potting mix. Mix the potting mix half and half with “the darkest richest blackest stuff from the bottom of your compost pile”. “If you are willing to see it through … lots of light, compost for food, don’t over water it and if you get flowers that would be so great to begin with”. Susan also gets the good Mom award of course!
Beware of old apple orchards
Steve from Jamaica, Vermont bought some land and found out the place used to be an apple orchard and would like to restore it to its former glory, apple trees and all. However, his hopes are dashed when Mike finds out the farm was in production around 100 years ago. He tells Steve to have the soil tested, but he may have potentially really bad news. Apple orchards at that time saw a lot of heavy pesticide use of the worst and most toxic pesticide, arsenic of lead. He explains that before Steve does much else he should get a hold of his county extension agent and test the soil and well water for old pesticides. “Old apple orchards are notorious, I can’t emphasize this enough. It needs to be your first order of business. It could be heavily contaminated with arsenic or lead.” Get the soil tested and call us back and let us know.

How to build a stinkbug trap
Jody from Lambertville, New Jersey called in to share his very popular technique of trapping stinkbugs. Mike briefed listeners on this ingenious homemade contraption that’s attached to the warm, southern-facing exterior wall of a house. But Jody corrected Mike that the stinkbugs aren’t looking for heat on the southern side of your home but rather the heat inside your home. Jody says: “It’s true, in my work I’ve found that they gather for heat, but it’s not the heat like we all thought. It’s turns out to be the heat of your house that they’re after. So as the heat of your house leaks out by any little crack or by a window, that’s more where they tend to go. They’re trying to get in for their hibernation process.” Jody is happy to report that his website, www.trapbug.com, is back up and running with instructions on how to build a stink bug trap, and he even recorded a new demo video to guide those who find themselves overrun with this insect.

The benefits of soil solarization
Danielle from central Illinois looking for tips on expanding her garden. She has big plans for her on acre of land, but is not sure how to prep the area. Mike explains the process of soil solarization. “Soil solarization takes a full season in the summer. The way you solarize soil is you till up the soil, you rake it as clean as possible, you level the ground perfectly, and then you saturate it with as much water as you can possibly get the ground to hold. And then you stretch clear plastic overtop and really pin it down at the sides so that area of soil cooks all summer long — we’re talking about June, July, August and September. Solarization is a great process; it gets rid of all the weeds, gets rid of any disease, it actually improves the health and texture of the soil.” Mike continues on to recommend the stages in which to build raised beds and where and when to plant fruit trees.
