Cabbage root fly Cabbage root fly is a small grey fly a bit like a small house fly. It lays it's eggs at the base of cabbage seedlings, the eggs hatch into maggots and then burrow down to feast on the new roots of your plants. Symptoms: Young plants will begin to wilt and eventually stop growing. If you bite the bullrt and pull up the plant you will see white maggots tucking into the roots. Control: The best organic method of control is to cover your calabrese with bionet micromesh to stop the fly laying it's eggs.
Make sure the net is sealed all the way round to prevent access by the fly. Cabbage collars. You can either buy or make these yourself from roofing felt or carpet underlay. The collars are a circle of material covering the soil around the base of the plant which helps prevent the root fly laying its eggs around the stem and stops the maggots burrowing down to the roots. These are naturally occuring microscopic worm which attacks the larvae of the cabbage root fly.
The nematodes are in your garden soil anyway you're just increasing the numbers. It is a non chemical product so is safe for use around pets and children. You will need to do a couple of applications but in my opinion it's well worth it as you'll also protect a whole host of other crops.
Cabbage White Caterpillars. The caterpillars of the cabbage white butterfly will reduce your plants to a skeleton within a couple of days so clearly it's best to keep on top of them. Look out for the yellow eggs of the butterfly under the leaves and brush them off. It's much easier to remove the eggs than the caterpillars so this is well worth doing. The caterpillars in the photo are babies, they'll get a lot bigger and do a lot more damage if you let them!
The best and easiest method however is to cover your crop with bionet as with root fly. Cabbage Whitefly The Cabbage whitefly is an aphid Like a greenfly, except white , it is less troublesome than other cabbage pests but worth keeping an eye on. The adults are tiny white insects which you'll find on the underside of the leaves. They produce a sticky substance called 'honeydew' which will probably cause a grey mould later. Remove any yellowing leaves at the base of the plant as they may be harboring aphid eggs.
You can wash off whitefly, honeydew and grey mould with a strong jet of water. Clubroot Clubroot is one of the most tricky diseases you'll encounter in the garden but with proper precautions it can be successfully controlled. If you start a new vegetable garden the chances of having clubroot are pretty slim and you can prevent it entering quite easily. If you do get clubroot the cysts survive for up to 9 years in the soil. You won't be able to grow any of the cabbage family Brassicas until it's gone so you've been warned!
The disease usually arrives in your garden through infected transplants or by walking from infected soil into a virgin patch. If you have an isolated garden you are unlikely to get it whereas you need to be more careful in established allotments. Symptoms: Poor growth with wilting leaves of a reddish-purple colour. If you pull up the roots you'll see swollen, knobbly deformed growth with a pungent foul odour.
In more advanced cases the roots will have dissolved into a slimy pulp. Prevention: If you have clubroot already seek out varieties with resistance to the disease, this will be clearly marked as an advantage on the pack.
Otherwise you'll just have to live with it, you can minimise it's effects by doing the following:. Cabbage White Butterfly Remember to keep an eye out for cabbage white butterfly eggs on your kale plants. Look under the leaves for the little yellow eggs and brush them off.
It is much easier to cover your crops with micromesh enviromesh if you haven't done so already. Make sure no butterfly gets in while you're doing it! They provide a crop between late September to early May.
Harvest the bottom leaves first, the top of the plant will continue to grow and produce new leaves. Larger, mature leaves have a bitter taste so it's best to remove them for the compost bin. This will stimulate the plant to produce more young tender leaves.
Harvest kale only when you need it because it does not keep well even in the fridge. I have an 18 metre long poly tunnel that I am watering with used bath water as the water table is so low. The tunnel runs, more or less, East to West with the beds going North to South across the tunnel. The other day I was given a packet of Curly Kale seeds. I've never grown them before so I'm looking for pointers as to 1 when to plant the seeds and 2 how to care for them.
Any advice greatly welcome. Thanks in advance Jannie. The sugar acts as an antifreeze to protect the veins, stems and leaves from freezing. WE like it because it makes the leaves sweeter but the plant could care less what we think.
Your putting the leaves in the freezer has no effect on the plant because you've already picked the leaves. Dumping ice around the leaves would also have zero effect. It's the roots and stems which are sensing the cold and producing the sugar. IF you were raising Kale indoors or in a greenhouse in water "Hydroponics" , you could chill the water down to 33 degrees and stimulate the Kale to produce the sugar. But that would be a very elaborate and expensive way just to get sweeter Kale and would hardly be worth it.
I have kale plants that have formed a cabbage above ground with roots in the soil and healthy leaves growing on the cabbage like kale leaves. Let us know how it turns out! There is a tall raised flower bed at the back of my house that was built with a plywood or Particle board type wood wall faced with brick. I was not thinking about this when I got plants but I planted kale and strawberries in the bed. Are they safe to eat? Or are they all just a waste? Will they ever be safe?
Any advice? Thank you. Particle board is not mentioned on that page but we would avoid it. Without knowing what chemicals it contains, we would only be guessing. That said, we would propose that you might be able to transplant the kale and berries. Hard to know how far along they are but if you get a new, safe, clean plot ready and get it done and then provide lots of TLC , you might have a harvest after all.
We hope this helps. Hello there, We moved into our home a year ago and it has a lovely garden. One item is Kale and right they are huge plants and have a lot of flowers on them.
From what I am gathering is that they are done? But I am not too sure what Bolting is? They have survived all winter long and their leaves grew all year long. Any advice you can provide will be helpful. Kale is a biennial 2-year plant, which means that it will produce leaves the first year, and then the next year or sometimes late the first year , it will form a flower stalk.
This stalk eventually forms flowers and then seeds; once the seeds mature, the plant dies shortly after. The act of forming that tall, central flower stalk is called bolting.
Sometimes the bolting response in a plant can also be caused by other factors, such as temperature or stress. If your kale plant is bolting, and it is the second year, then the plant will not last much after the seeds form—you may want to pull it up and start over, unless you plan to collect seed though if the kale is a hybrid, the offspring may not be similar to the parents.
Once kale bolts, the leaves take on a stronger flavor, at which point harvesting usually stops. Hope this helps! Hi , I am new to gardening and moved into a house with kale already growing.
Stem is over 4' height, small and sparse kale leaves between growth spurts and has long shoots with yellow flowers on the top. If this is edible kale, the yellow flowers are a sign that the plant is bolting.
If you have not already, cut the stems that you want and save or cook them. You can cut the flowers for a vase or leave them for appearance, but as an annual, the plant is almost done. My kale is starting to flower, am I supposed to pull the flowers off like for basil or broccoli?
If you have not already, harvest any leaves that you want and save or cook them. Pulling the flowers is not likely to halt the bolting process—a sign that it is too warm for the plant to produce leaves. You can harvest the leaves as long as the taste is appealing. After the plant bolts sends up flowers the leaves may become bitter. I purchased a kale plant and it was growing; however, can I plant it outdoors I live in MN and will it survive the winter,or should I just toss it and purchase a plant or seeds next spring?
Kale can take a light frost. In fact, kale is best in the fall after exposed to a few light frosts. You can always blanch and freeze to store over the winter. Plant new seeds in the spring. Skip to main content. You might want to mix in some compost to increase its fertility before planting. Once the soil is ready, sprinkle a row of kale seeds across it. The video from Burpee Gardens shows you how to direct sow the seeds in your garden.
Later on, it also provides tips for starting kale from transplants. You can eat the tiny kale plants you cut away, either on their own or in a salad.
If you prefer, you can start kale seeds in small pots indoors, then move the plants out to the garden later on. Transplants need to be hardened off, or acclimated to outdoor conditions. To harden off your kale before transplanting, bring the seedlings outside in the early morning for a few hours. Return the seedlings to their spot indoors. The next day, bring the seedlings outside again, for a bit longer.
Increase how long your plants spend outside over a period of five days, until they are spending all day and night outdoors. At that point, they will be ready to plant in your garden. Carefully place the plant in the soil, filling in the hole. When you plant kale depends on when you want to harvest and eat it. In areas where the summer is hot, there are two main planting times: in the early spring and in the fall. If you are going to plant kale for a spring harvest, direct sow the seeds in the garden about two weeks before the last frost in your area.
The seeds will germinate in soil temperatures as low as 40 degrees Fahrenheit. You can start seeds indoors a bit earlier than direct sown seeds.
Indoors, you can plant seeds about seven weeks before the last frost in your area. Start hardening off and transplanting your seedlings a week or two before the last frost date.
When you plant kale for a springtime harvest, the goal is to have the kale ready for picking before the weather in your area gets too hot. Since kale needs at least two months from time of planting to harvest, when grown from seed, you might not be able to plant it in spring if temperatures in your area reach 80 degrees on a regular basis early in the spring.
Leaving kale in the garden until after a few frosts have passed helps make it taste sweeter, as the cold temperatures turn starch in the leaves into sugar. To have your kale plants ready for harvest by early winter, start the seeds about three months before the first frost date in your area.
