🌱 Allotment Jobs in March (UK Growing Guide)
Allotment jobs in March are all about preparing for the main growing season ahead.
Longer days, slightly warmer soil, and that feeling that the growing season is properly beginning. It can still be cold and unpredictable in the UK, but this is the month where preparation pays off.
If February was about planning, March is about action.

What to Sow on Your Allotment in March
March is a big sowing month. Depending on your location, you can start sowing both indoors and outdoors.
Sow Outdoors (if soil is workable)
• Broad beans
• Peas
• Spinach
• Spring onions
• Radish
• Lettuce (hardy varieties)
• Carrots (under cloches in colder areas)
• Beetroot (late March)
If your soil is still heavy or waterlogged, don’t force it. Wait until it crumbles nicely rather than sticking together.
Sow Indoors or Under Cover
• Tomatoes
• Chillies
• Peppers
• Aubergines
• Cabbage
• Cauliflower
• Leeks
A windowsill, greenhouse or cold frame works well this time of year.
What to Plant in March
March is ideal for getting early crops established.
• Onion sets
• Shallots
• Early potatoes (chitted)
• Garlic (if not already planted)
• Fruit trees and bushes
• Rhubarb crowns
Planting early potatoes now can give you a harvest as early as June.
What to Harvest in March
Harvests are still light, but you may have:
• Leeks
• Sprouting broccoli
• Kale
• Winter cabbage
• Parsnips (before they go woody)
March is often the “gap month” before fresh crops start coming through again.
Maintenance Allotment Jobs In March
This is where the real work happens.
• Prepare beds by clearing weeds
• Add compost or well-rotted manure
• Repair netting and supports
• Install water butts
• Finish pruning fruit bushes
• Divide overcrowded perennials
If you do nothing else this month, improve your soil. It makes everything easier later.
Common March Problems
UK weather in March can be unpredictable.
Watch out for:
• Late frosts damaging seedlings
• Slug activity increasing
• Waterlogged soil
• Birds pulling up young shoots
Keep fleece handy and avoid overwatering seedlings.
Pro Tips for March

March is a good time to:
- Finish pruning apple and pear trees (if not already done)
