Vegetable Seeds to Sow in March

What Vegetables to Sow in March from Seed to Harvest

I received a very nice tweet last week from @NicolaHurrell, saying she very much enjoyed my what to sow in February post and asking if I was going to do one for March. Well, since Nicola asked so nicely, I can hardly say no. 🙂

So without further ado, here are a selection of seeds that can be sown right about now.

Best Vegetables to Sow in March


Both early and maincrop carrots can be sown in March. Early Nantes and Autumn King are long-standing, common varieties that can be found free on the front of veg mags everywhere at this time of year.

I sow carrots in containers, as my soil is too stony and growing this way beats carrot fly as they can’t fly high enough.

If sowing direct, don’t be shy about sprinkling plenty of seeds down the row. There are literally thousands of carrot seeds in a packet, and you can always thin out if too many germinate.


Beets are one of my favourite things to grow. They’re reliable, and the seeds are big and easy to handle. If you thin your beets out, don’t discard the thinnings. They re-root with no fuss at all, increasing the yield from the sowing.


Parsnips are also worth a try. They need a long growing season, but many believe this leads to us growers sowing them far too early, and there is a school of thought that their notoriously fickle germination is down to this. I have struggled to get them to germinate in the ground, so over the last couple of years, I’ve done grown them in toilet roll modules and florist buckets.

Broad Beans and Peas

It’s certainly not too late for a row of broad beans, even if you’ve overwintered some already. An extra few plants will make a good succession crop, and the surplus will freeze well too.

Peas are a hardy seed, and many are also happy to be sown now. Try Hurst Greenshaft or Early Onward for popular, reliable varieties. Generally, I’ll sow three or four into individual pots to plant out later, but I’ve also sown into old lengths of guttering.

Fill the guttering with soil, and screwed pieces of wood into each end to keep the soil and water in. Once the peas are ready to be planted out, dig a little trench, remove the wooden ends and slide the whole lot out of the guttering and into the trench.

Make sure there are plenty of holes in the guttering, and the soil is not too damp, or mould might set in. Growing in gutters and pots means you can start them off indoors if you have the space.

If you’re sowing in the ground, a neat idea is to plant a bunch of seeds together at the end of the row. These can then be transplanted into the row to fill any gaps.

Perpetual Spinach and Radish

Other good seeds to sow and perpetual spinach and radish. Perpetual spinach will grow very quickly once spring gets underway and provide leaves well into winter, and regular three weekly sowings of radish will produce the peppery roots all through summer.

  1. Ive had much better success with putting parsnip seeds on a wet paper towel, and then placing that inside a sealed takeaway container in the sunshine. As the sprout pot them straight into compost in pots to grow on. The ones that dont strike get binned. My parsnip strike rate went through the roof last year because of it!

  2. I’ve tried sowing peas into/onto guttering but they stuck and refused to budge out onto their nice bed! I’m just going to use the seeds in a pot thingy and separate them to plant out. (As well as sow along a row way.)

    Yippee! Do you think it’s SPRING!!!

  3. I came across your email newletter this evening. I follow you on Twitter. I am a container gardener here across the pond in central Florida USA. I enjoy your posts and pictures.

  4. I am not keen on parsnips generally. But I love baked baby nips.
    So plant them nice and close in the rows and thin out when thumb sized for baking-yummy. They are totally different.
    When you are left with a consistent row of wider spaced plants just grow them to adulthood.
