If you are new to vegetable growing, you may well be wondering what you can safely plant or sow in March. What you can plant in March (or sow, for that matter) depends a great deal on where you intend to sow/plant your vegetables. To make things a little easier, we have split what to plant in March into groups based on location for you.
Balcony Planters and Window Boxes
If you are planning on growing your veggies in balcony planters or window boxes, you can now start sowing:
- Cut-and-regrow salad leaves like ‘Dragon’s Tongue’ salad rocket or ‘Provencale Salad Mix’, for instance
- ‘Red Choi’ (Pak Choi F1) or ‘Fizz’ kale
You can also plant basil seedlings, other new herb plants and ‘Red or Green Salad Bowl’ loose-leaved lettuce plug plants.
March is also a good time to sow cut-and-regrow salad crops in your patio containers or pots.
Unheated Greenhouse, Lean-to or Sunny Porch
Here, you can start sowing leeks (especially the ‘Northern Lights’ variety) and more of the cut-and-regrow salad varieties mentioned above. You can also start planting early, quick-cropping potatoes like ‘Rocket’ or ‘Swift’, for instance, in grow sacks or pots.
If you have a heated propagator or a heated greenhouse, you can sow the following in March:
- Club root-resistant F1 ‘Crispus’ Brussels sprouts
- Curly leaved ‘Afrodite’ parsley
- F1 ‘Diablo’ and ‘Yellow Bell’ sweet peppers
- Self-blanching ‘Loretta’ celery
- Shallot F1 ‘Ambition’
You can also plant indoor tomatoes, including beefsteak-type ‘Costoluto Fiorentino’; cherry-type ‘Gardener’s Delight’and/or F1 ‘Sweet Million’ or the delicious plum-type ‘Yellow Pear’ tomatoes in your heated greenhouse now.
Using a polytunnel, March is perfect for sowing:
- Cut-and-regrow cress and mustard
- ‘Carouby de Maussane’ mangetout peas
- ‘Shiraz’ purple-podded peas
- ‘Long White Icicle’ radishes
- F1 ‘Red Kitten’ baby salad leaf spinach
- Winter purslane
If you have sown broad beans in February, you can now plant them out in your polytunnel.
