This time of year, garden insects are often a topic of questions or discussion. Plants and pests have grown up alongside each other, and now there may be a little too much feeding going on for your liking. It is also about now that the natural insect predators show up to take care of the damaging insects for you.
It is that time of year for plant galls (or things that look kind of like a gall anyway) to be more obvious in the home landscape. They got a start long ago when bud swell was going on earlier this spring, but they are more noticeable now.
Outdoor insects have endured quite well, despite our hopes that either the cold or snow would have done them in for the 2021 gardening season. The cold is more of a factor than the snow. The snow will act as insulation for those overwintering insects at or below the soil line. (Side note: This also is why our perennials do so much better in the spring if covered with snow all winter compared to open and exposed to the wind and cold temperatures.)
Now that our days are warming up, so are those outdoor overwintering insects along with our not-so-favorite winter indoor pests.
Note: this is the fourth post in a series on fruit trees. Read part one.
As we approach mid-January, there may be more going on inside than outside for gardeners. Perennial beds covered in snow enjoy the protection from drying winter winds and the winter sun (if we ever see sunny days anytime soon). For some of us, traditional bird feeding started weeks back.
Late summer and early fall provide us opportunities to learn more about the insect world. With our outdoor bloom show coming to a close, there are a great many insects that had been feeding on flower parts that are now looking around for something else to eat or thinking about vacationing where it is warm – inside our homes.
By this time of year, woody plants have taken care of business, meaning the foliage already has produced the energy needed to form buds for both foliage and flowers for next year. If there is a fruit or pod containing seeds, that is nearly, if not already completed, as well. In the next few weeks, plants will get the signal that fall is on the way and begin to set up for the eventual color change and leaf drop.
Gardeners have been seeing lots of lumps, bumps, and blobs on different kinds of leaves throughout the home landscape, or in parks and the forest preserves. It is not uncommon, as this occurs annually. What is uncommon is the generous number we are seeing this year.
Master Gardener Help Desk emails have really been different this past two weeks. Our early spring challenges have left and along came the first of our summer concerns in the landscape and vegetable beds. The list turned into more than a column’s worth, so going to hit the big ones this week:
In the middle of January, not a lot is going on outside in the home landscape except the feeding stations, kept full of seed and suet for birds, cobs of corn for the squirrels and maybe a salt lick for other kinds of wildlife. Perennial beds covered in leaves or snow enjoy the protection from drying winter winds and the sun (if we see sunny days).
Fast-forward past the holidays to springtime. You notice moths flying around the kitchen and pantry. Maybe you see them hovering around the light over the kitchen table or at a window. That is solid proof that you have Indian meal moth lurking in some leftover flour products, likely from all the baking you did many weeks earlier.
Back to present day, you do have the opportunity to avoid having to deal with this problem, and all the inspecting, finding, cleaning and disposing that goes with it.
This season gardeners have been seeing many lumps, bumps and blobs on all kinds of plants throughout the landscape, in parks and forest preserves. It is not uncommon since this occurs annually, what is uncommon is the generous number of these growths we are seeing.
