Over the Garden Fence 2019

Winter Damage Beyond Boxwoods

There has been a lot of media coverage and homeowner concerns about boxwoods, and this has overshadowed overwintering damage on a range of other landscape plants from trees down to small fruits and perennials. First thing's first – winter hardiness. To some extent, gardeners have been cheating...

Flowers and Foliage for your Yard

Every gardener has their favorite flowers that seem to make it into the garden each year, maybe in a different spot, worked into the design a bit differently than last year, but they are there. It is a little easier to have your favorites if your yard gets lots of sunlight every day. Look at the...

Taking Care of Winter Pantry Pests

Back in December, this column talked about doing our best to prevent an outbreak of any one of several kinds of pantry pests in the home. Some of what was shared included sealing bulk amounts of dry pet foods, including the birdseed used all winter for outdoor feathered friends, and limiting,...

What to Know about Evergreen Woes

Recent weather events have taken a toll on some of our older established evergreen trees. Most recently, our heavy wet snow that collected on the evergreen boughs added many pounds of weight and broke out branches throughout the canopy. The wind played a big part of that damage, creating more...

Swarming Insects this Season

What do bees, ants, and termites have in common? At some point in the year, they all swarm. Our honeybee may be the most obvious as the queen gathers up thousands of support bees from the existing hive and heads off to find another location to set up shop. You may see those swarms hanging in trees...

Plants and Insects Coming Alive in Northern Illinois

Plants are beginning to get the right signals from Mother Nature that spring has begun. Foliage and flower buds have begun to swell and expand, and will do so more quickly with the more spring-like weather. Buds have been protected all winter with insulating bud scales that will soften with the...

You can place spinach and lettuce in the 45-degree group, and peas, cabbage, Swiss chard, radish, and beets in the 50-degree group. Other vegetables can...

Flowerbeds and Vegetable Gardens Need TLC

No one wants to hear the word "rain" these days. Clearly all the wet weather has changed the way we planted the vegetable garden and our flowerbeds this year. I have heard people describe spring plantings as "I went ahead and mudded them in." Not the best practice for seeding and transplanting, of...

Cold Weather Challenges Flowering Buds

When talking about flower buds on our fruit trees and flowering ornamental plants, a couple of plants come to mind. The first is the peach tree. Like other fruit trees, peaches produce flower buds every year. It is just a gamble whether or not we have severe winter temperatures during the winter....

Finally Some Drier Weather

Gardeners and farmers have had a chance to catch up on planting (finally). As I was traveling south, then east, before coming back north, I saw a lot of the state over the last week, and it showed just how behind planting corn and soybeans has been, with many fields just now being worked and...

Are your Houseplants Ready for Summer Vacation?

An old joke goes: "Why do you put your houseplants out for the summer? So I can slowly kill them all winter back in the house." Well, there is a certain amount of truth to that. We cannot always get them inside for the winter when we should, cannot always supply the right kind of light for all of...

Plants, diseases & bugs over winter

Our weather can influence how well our landscape plants over-winter. Boxwood, rhododendron, azaleas and evergreen groundcovers get through the winter without all the desiccation associated with cold winters and come out in the spring looking a lot better. Limited or no snow can drive the frost...
