Sowing Courgette Seeds: A Step-by-Step Guide

Ready to get your courgettes growing? Here's everything you need to know about when and how to sow courgette seeds for a bountiful harvest.

When to Sow Courgettes Outdoors

Here's the lowdown on when and how to sow courgette seeds outdoors:

  1. Wait for the threat of frost to pass: In most UK regions, this happens in late April or early May.
  2. Check the soil temperature: Use a soil thermometer to ensure the soil temperature is 10°C or above.
  3. Gradually acclimate the plants to the outdoors: Plant the seedlings after the risk of frosts has passed and expose them to the elements for a week or two before transplanting.

When to Sow Courgettes Indoors

Sow courgettes indoors in pots between March and May. The seedlings will emerge in 7-14 days.

  1. Use a small pot filled with compost to sow the seeds.
  2. Keep the seed tray in a warm, sunny spot.
  3. Transplant seedlings outside once they have 2-3 leaves and the risk of frost has passed.

Fast Growing Crops for March

Searching for what to plant in March? Consider courgettes - these fast-growing crops are a brilliant choice for early sowing.

Natural Ways to Get Rid of Slugs

Tired of your courgettes being snacked on by slimy slugs? Check out these natural solutions:

  • Make a beer trap: Slugs can't resist the yeast in beer, so they're bound to fall in and drown.
  • Use wood ash: Scatter wood ash around your garden to deter slugs. The sharp texture and taste of ash will keep them at bay.
  • Plant slug-repelling herbs: Try growing mint, garlic, or marigolds to keep slugs away from your courgette plants.
