Now Is The Time...

  • Turn compost piles and add fall cleanup items.
  • Harvest gardening tools from the yard and garden. Winterize the wooden handles with linseed oil. Clean and sharpen metal parts.
  • Winterize power equipment. Change oil, sharpen blades, replace filters and you’ll be ready to roll in Spring.
  • Consider late fall planting of trees and shrubs. Bargains can be had at local garden centers.
  • Plant bulbs right up until the ground freezes.
  • Make sauerkraut from locally grown cabbage.
  • Buy Penn State soil test kits to use as stocking stuffers.
  • Use the lawn mower to deal with tree leaves. Allow them to drop in place or wind-row for pick up.
  • Visit local apple producers for unique varieties such as Cortland, HoneyCrisp, Empire, and IdaRed.
  • Fill raised beds with compostables, manure or leaves so it can breakdown over winter.
  • Test drive the snow blower.

Household Invaders
Scott Guiser, Extension Educator-Horticulture

Sounds scary...household invaders. But we’re not talking about a break in...more like a sneak in and the culprits have six legs not two. About this time of year we get lots of calls about insects that make their way into homes. The biggest offenders are Boxelder Bugs and the Brown Marmorated Stinkbug.

Boxelder Bugs have been around a long time. In the past, when I talked to someone on the phone about them there was often one crawling around my office because the window I look out of does not seal really well. The bugs made their way in through the tiny crevices. Since recent construction has removed the near-by box elder trees that were their summer host, I haven't seen them. Boxelder bugs feed on boxelder trees, as well as other maples (boxelder is Acer negundo, the same genus as maple) and ash. In the fall they look for a cozy warm place to spend the winter, starting out on the sunny sides of building and moving inside if given a chance. They must have good heat sensors.

These red and black bugs do not do any damage to homes. In fact they don’t do much damage to plants either although they do suck sap from leaves and seeds of boxelder. If anyone cared about this plant it might be an issue but boxelder trees are usually considered a weedy tree.

Most folks don’t appreciate big insects crawling around the house and bug phobic people get really agitated. The solution to boxelder invasion is to seal up the cracks and crevices they use to get in. Once inside, simply sweep or vacuum them up. They do not reproduce inside. If you make a direct hit with an insecticide, you will kill them but the vacuum cleaner or shop-vac is quicker. I suppose you could consider insecticide applications outside where they congregate but even here, think twice before spraying. First, if they can’t get in the house, what’s the problem? And given the poor control provided by insecticides and the ease of the vacuum, why not keep things simple. If you can find the host boxelder tree and remove it you will have a big impact in future years.

The Brown Marmorated Stinkbug is a recent phenomenon. Actually, one of Penn State’s extension educators in Lehigh County helped to document the first sightings in 1998. It is native to China.

This bug can cause plant damage. It feeds on several fruit species. But the problem most folks have with them is when they get inside. They fly, they stink a bit when crushed and are creepy in a bug-like way to most folks.

The control measures for the stinkbug is the same as for boxelder bugs. Seal cracks and crevices to prevent entry. Vacuum up those that get in. Realize that they do no structural damage of any kind and do not breed inside.

Some folks think these home invaders are reproducing inside because they see additional bugs after the initial removal. The insects are simply emerging from hiding places. Well, maybe not hiding but previously infested areas. It seems to me that a common entry point for stink bugs is attic areas which are often hard to seal completely.

Penn State’s Online Booklet Makes Apple Preservation Delicious, Easy Fun

Pennsylvania is the fourth-largest producer of apples in the United States, and since many Pennsylvanians will be taking advantage of this delicious fact this fall, Penn State's College of Agricultural Sciences offers helpful apple preservation and cooking tips through its online booklet, "Let's Preserve: Apples". Produced by the Department of Food Science, the booklet is part of the 14-publication "Let's Preserve" series, which provides advice on how to safely can, freeze and preserve fruits and vegetables. Each booklet focuses on one fruit, vegetable or home food-preservation topic. The series -- found online at http://foodsafety.cas.psu.edu/lets_preserve.html -- provides instructions in a simple, recipe-style format that takes the guesswork out of food preservation.  

"Let's Preserve: Apples" covers everything from freezing and canning apples to recipes for the perfect apple butter. The booklet also helps people to use proper procedures for avoiding canning mistakes and keeping their food safe. "It is safer to use apples picked from the tree, and to avoid using “drops,” says Penn State food safety specialist Martin Bucknavage. "Apples on the ground are more susceptible to the growth of molds that increase the risks of mycotoxins, which are potent toxins produced by several mold species. The key to safe preservation is to always use sound fruits and vegetables."

"Let's Preserve: Apples" also suggests using crisp, firm apple varieties for freezing and includes a chart that shows each apple variety's texture and availability by month. For canning, apple varieties that will keep their shape and texture during the procedure are best. The publication notes that canned food always should be consumed within a year to ensure food safety.

Additional information about preserving homegrown fruits and vegetables is available by visiting the Penn State Food Safety Web site at: http://foodsafety.cas.psu.edu.

Single copies of "Let's Preserve: Apples" can be obtained free of charge by Pennsylvania residents through county Penn State Cooperative Extension offices, or by contacting the College of Agricultural Sciences Publications Distribution Center at (814) 865-6713 or by e-mail at AgPubsDist@psu.edu.
