Cabbage Collars Green Gardener Economy Pack of 100

Product Information

Cabbage worm – are the offspring of moths. Their eggs are scattered on the underside of leaves, and when hatched the worm eats into the foliage damaging the plant. Try covering plants over with netting once planted to prevent the moth from landing. For consistent crops of tasty, high-quality caulis, it’s best to choose F1 hybrid varieties, and if you’ve ever had problems with clubroot disease, select resistant varieties. Look too for varieties with an RHS Award of Garden Merit (AGM), which shows they performed well in trials – see our list of AGM fruit and veg for RHS-recommended varieties of cauliflowers and many other crops. There is more than one way to make a plant collar. You can use a variety of materials as the basis for a plant collar, including: Brassica Collars offer a simple solution to stop the cabbage root fly, a notorious allotment pest that can cause serious damage to your brassica crops including broccoli, cabbages, cauliflowers, calabrese and brussels sprouts.

cardboard, enough to create a 6- to 8-inch circle to go around each plant or recycled rounds of cardboard from frozen pizzas Install the collar around the plant by slipping the cut line around the plant’s stem. Once in place, overlap the cut line slightly until the small flaps are positioned loosely around the plant stem. There should be enough space for the stem to expand, but not enough for the flies to gain access to the soil around the base of the plant. Step 6 Once in place, staple the overlapped cut line of the circle closed in two or three places. Tips For Using Cabbage CollarsWe want a plant collar in the shape of a cylinder, with an open top and bottom. A few options that don’t require much work include: To do this, once the cauliflower head is the size of a golf ball, tie the outer leaves loosely over the head of the vegetable and secure them in place with twine. Leave enough room so the head can continue to grow unhindered. This will both protect it from the elements and the sun from discoloring it. Cauliflowers are best eaten fresh, but can be stored in a fridge for a few days – they keep better with a few leaves intact. Cauliflower florets can also be blanched then frozen.

I mentioned a few weeks ago that not only do I have to lime my plot because our soil is so acid, but I also have to use brassica collars here to stop cabbage root fly. I have bought 180 of them this year so far and used the lot and I already had some from previous years which have been used as well. Stop cabbage root flies laying eggs by placing collars over the base of your young plants at planting time. This barrier method often proves more effective than chemicals and is ideal for organic growers reluctant to use chemical products on their harvests. Indoor-raised plants must be hardened off so they are acclimatised to outdoor conditions before transplanting. As with any vegetable crop, companion planting with beneficial plants can help to reduce the threat from pests. Because female cabbage root flies lay their eggs on or right next to the base of host plants, shielding the soil around the base of the plant is key to preventing this pest from becoming problematic. This is best performed within a few days of planting out susceptible cole crops.Summer varieties – usually sow indoors from winter to early spring. They are fast growing and form smaller heads, ready to harvest in four or five months. They are generally easier to grow successfully than later varieties, especially if harvested before any hot, dry weather. Cover your crops – use a very fine mesh netting to protect plants from pests such as flea beetle, egg-laying moths and butterflies (which produce caterpillars) and birds. These net cloches allow sunlight and water to pass through while preventing pests from getting in Varieties with orange, purple or green heads generally keep their colour when cooked, although boiling can fade purple heads. Position the flaps so that they cover as much of the opening as possible, without damaging the plant stem. Typically I recommend covering cole crops with floating row cover to keep pests away, but in the case of cabbage root flies, covering them too early may actually trap newly emerged adult flies underneath the row cover, so instead I turn to making cabbage collars to protect my plants. I put a collar around each plant by late April because the first generation of adult flies typically starts to emerge in early May through June here in my Pennsylvania garden. Making Cabbage Collars What You’ll Need:

Fabric roll tube– after a roll of fabric is used up, the leftover cardboard cylinder will give you enough material for many plant collars. You might be able to find this item from an upholstery shop, a fabric supply store, or a craft store (such as JoAnn’s, Michael’s, etc.) Different varieties grow to various sizes, to suit whatever space you have available, from huge heads (curds) up to 30cm (1ft) across to mini-caulis just 10cm (4in) wide. Winter varieties tend to be larger and slow growing, taking up a lot of room for six months or more, so if you’re short on space, choose smaller, faster-growing summer or mini varieties. Discoloured heads – protect the developing curds from sun and frost, which can turn them yellow or brown, by folding the leaves over the head and tying in place with string if necessary. Of course, plant collars will add a little extra effort to your gardening. However, it is worthwhile to protect your plants from devastating pest damage.

Delivery

While you can certainly buy brassica collars for your plants, these simple tools are just too easy to make at home with materials from your recycling bin to not try at least once. Personally, I prefer cardboard. It is easy to work with and will ultimately decompose. Just follow these steps to make your own brassica collars:
