There are usually a few things that you can harvest in March, such as spring onions and spring greens, and it’s a great time to get ready for a new season of growing too. Towards the end of the month you can start planting seed potatoes too.
What to harvest
If you’ve been growing over the winter there should still be plenty to harvest this month… Green Sprouting Broccoli spears can be cut off from mature plants now, Spring Greens (and late Winter Greens) can be harvested as whole heads. Spring Onions can be picked as soon as they reach the right size. You should be able to harvest lots of winter salad leaves, spinach and chard, as well as any autumn planted pak choi and tatsoi. And of course, there should be plenty of kale to go round!
What to plant
March is not a big planting month, but you can plant out onion and shallot sets. If your plot is waterlogged, then you can plant them in pots/containers under shelter. Meanwhile, keep chitting seed potatoes (and warming the soil) for planting them later on in the month.
Jobs for the veg patch
The main focus this month is getting ready for spring – build new beds, fix broken greenhouse window panes, top up existing veg beds with plenty of organic matter (well rotted manure is great, or good quality compost), build compost bins and so on.
It’s also a good idea to mulch any fruit plants that you have been growing.
Watch out for frosts, heavy rain, snow and other classic British March weather….keep vulnerable plants protected with cloches or fleece.
