Weed Control In General

Have you had just enough of the weeds growing in your flower bed? I know I have. As an avid gardener with many other plates spinning in the air, I simply do not have the time to get out in the yard and hand pick these weeds or even mix up a batch of chemicals, walk through the yard and spray each weed individually hoping to kill them.

Mulching For Weed Control

Mulching beds is an important part of a sustainable landscape.

Pulling weeds is a job that never stops. Every time weeds are removed, new weed seeds germinate, creating the problem all over again.

Mulches work to stop this by blocking sunlight from reaching the soil service. Most weed seeds need light to germinate. The light tells them they're close enough to the soil surface to sprout and grow a new plant.

Oxalis: Beautiful Flowers, But Still A Weed

If you've ever had oxalis in your flower bed, you know just how pesky this weed can be. You can identify the weed with a few key characterists, such as the clusters of beautiful purple flowers it produces. The foliage looks a bit like a clover or shamrock, as illustrated by the image here.

Gardeners can utilize the intense heat of the summer sun to control soil-born pests in vegetable gardens. Through solarization, you can use heat from the sunlight to control pathogenic fungi, nematodes, and weed seeds in the soil.

Solarization is the process of heating the soil in our beds under a covering of clear plastic using the energy of the sunlight, similar to the way a greenhouse might work. It can only be used on an empty bed, so as you remove vegetable crops you might have a perfect opportunity to use solarization.

How To Manage Your Gripe Weed

Many weeds in the landscape can cause a gardener to gripe, but when the weed is specifically named after a gardener's complaints, then you know you have a real problem on your hands.

Gripe weed has become more common in our area over the past decade. You should accept eradication of a weed as impossible, but management and control are well within our reach. Hand-weeding and herbicide on the foliage work well. Shield or cover nearby desired ornamental plans when you're spraying herbicide.

Go down the pesticide aisle at your local nursery. There are so many different herbicides to choose from. There's a difference between the different types of herbicides. But herbicides are just one of the ways to manage weeds.

Mowing your lawn at the right height is actually a very effective management technique against weeds. If you mow your grass at the right height, you'll need much less herbicide to manage weeds.

It would be nice to think we could take the winter off from worrying about weeds in our landscapes. Unfortunately, there are many weeds that thrive in the mild to cold temperatures of winter, both in our beds and in our lawn.

Don't forget to keep up with weeding this winter. Be proactive. Use mulches.

Mulches are our very best defense against weeds in our beds. Mulches work when the mulch layer is about 2". Mulch works by blocking sunlight from triggering weed seeds to germinate.

Weed control is a constant part of maintaining a landscape, particularly here during our long hot summer. That's something that will never go away. But you do need to make sure you're doing the right things to make sure your efforts produce the best results possible.
