What NOT to do in the garden in December

What should we be doing in the garden in December? Well, the books and magazines have some pretty mad ideas.

“Sow begonias” No. The chance of the tiny seedlings damping off is pretty much 100%. Wait.

“Prune summer flowering shrubs and roses” No. A few mild days will prompt new growth that will be frosted as soon as we get a cold snap. Shorten them to prevent wind rock, yes, but leave the final pruning till later.

“Replace worn turf at the edges of lawns” No. As soon as we get a hard frost the turf will curl up and dry out.

“Protect carnations with black cotton against birds.” What?! Apart from the fact that so much cotton is now synthetic and not actually cotton at all and is too tough for even a big fat pigeon to break if it gets tangled, I’ve never seen a bird do anything to a carnation except eat a few aphids off the buds.

“Treat tulip clumps with a contact weedkiller and then a weed preventative.” Really? How many clumps of tulips do you have? How long will it take to pull out any weeds by hand? And how long will it take you to go to the garden centre, hunt for safe weedkillers and weed preventers, come home and treat the weeds? Need I say more?

“Spray rhododendron buds with bird deterrent”. No. Bird deterrents are for buildings, not buds, and not even the “Buy this item and get 90 days Free Amazon Music Unlimited” will tempt me.

“Cover ground around newly planted camellias and rhododendrons with 12in of straw to prevent roots being frozen.” How’s your straw supply holding up? Got pet rabbits? How long do you intend to spend collecting the straw from the four corners of the garden where the wind has dumped it?

So, take what you read about December jobs with a little scepticism, And, if in doubt as to whether you should do it now or at all: probably – don’t. Except:
“Feed the birds.” Yes. In winter, it’s essential

Growing Cabbages from Sowing to Harvest

July 30th, 2018 | News | 0 Comments

A vegetable plot isn’t complete without cabbage. Shredded, stir-fried, steamed or baked, there’s not much you can’t do with one! And with a little planning it’s even possible to enjoy cabbages year round.

Read on or watch the video to find out more about growing cabbages.

 

Types of Cabbage

From green to Savoy, there’s a fantastic range of cabbage varieties to choose from, offering different shapes, colours and textures.

Cabbages are grouped according to when they’re harvested. Spring cabbages are ready from mid to late spring. Summer cabbages crop from summer into early autumn, while autumn cabbages and winter varieties cover the remainder of the year. Savoy cabbages have a long harvest period, stretching from autumn all the way through winter to early spring.

 

Where to Grow Cabbage

Many cabbage varieties will tolerate below-freezing temperatures. But for the healthiest growth they need an open, sunny site and rich soil. A bed improved with compost or well-rotted manure is ideal, and will appreciate a further boost in the form of an organic general-purpose fertiliser raked into the ground at planting time.

In a traditional crop rotation cabbages follow on from peas or beans, which naturally lock nitrogen away at their roots. Left in the ground when the crop is cleared, these roots will help to feed the cabbages that follow.

Unless your soil is naturally alkaline, sprinkle garden lime onto the soil either after you’ve dug it over, or rake it in at planting time.

 

How to Sow Cabbage

Cabbages may be started off in an outdoor seedbed to transplant once they’re bigger, or under cover into modules or pots, which also enables an earlier start to the season.

Prepare seedbeds by treading on the ground in a shuffling motion before raking to a fine tilth for sowing.

When you sow depends on what type of cabbage you’re growing. Summer cabbages are the first to be sown, in mid spring, followed by autumn and winter types later on in spring. Spring cabbages are sown from the second half of summer to harvest the following year.

Mark out drills about half an inch (1cm) deep and 6 inches (15cm) apart. You can use a string line to ensure nice, straight rows. Sow the seeds thinly along the row then cover over and water. Keep the soil moist. Thin the seedlings once they’re up to one every couple of inches (5cm).

Under cover, start seeds off in plug trays of all-purpose potting soil. Sow two to three seeds per cell about half an inch (1cm) deep. After they’ve germinated, thin to leave just one seedling per cell. Or sow into trays or pots then transfer the best seedlings into individual cells or pots to grow on.

 

Transplanting Cabbage

The seedlings are ready to transplant about six weeks after sowing, by which time they should have grown at least three to four adult leaves. Make sure spring cabbages are transplanted no later than early autumn, so they can establish before winter bites.

Plant your seedlings into prepared ground. Leave about 18 inches (45cm) between each seedling. Additional rows of spring or summer cabbage should be set around the same distance apart, while autumn and winter types need a little more space between rows – about 2 feet (60cm) is ideal.

Firm your cabbages into the ground well, then water generously to settle the soil around the roots. Seedlings transplanted from a seedbed should be lifted up with as much soil around their roots as possible. This avoids unnecessary root disturbance, helping the seedlings to quickly adapt to their new growing positions.

 

Caring for Cabbage

Cabbages are prone to attack from pigeons and caterpillars of the cabbage white butterfly, also known as cabbageworms. Wire mesh will protect seedlings against pigeons, but to stop butterflies from laying their eggs on the leaves it’s best to use netting during the summer months.

Another clever technique is to grow nasturtiums close by as a sacrificial crop, also known as a trap crop. Caterpillars prefer nasturtiums, so they’ll be more likely to eat these instead of your cabbages. Mint can be used to help deter flea beetles.

Continue to water cabbages as they grow. Ensure they have all the space and nutrients they need by carefully weeding between plants with a hoe or by hand. Winter cabbages are very hardy but during exceptionally cold weather they may need some form of cold protection such as a row cover tunnel or cloche. In very cold regions, growing cabbages in a greenhouse or cold frame is a great way to guarantee a winter-safe crop.

 

How to Harvest Cabbage

Use a sharp knife to cut your cabbages once the heads have firmed up. Savoy and other winter cabbages benefit from a light frost to bring out their flavour. Spring cabbages may be harvested young and loose as greens for repeated cutting, or left to grow on to form a tight head of leaves. Either way is totally delicious!
