Save on seed starter trays this growing season AND help reduce waste by using what you've got at home. Here are some of our top DIY seed starter materials: newspaper cups, toilet rolls, egg cartons and our favourite, eggshells themselves! The seedlings can be planted directly into the ground as all of the materials are 100% biodegradable.

Here's a quick 'how to' for using eggshells as mini plant pots. They're also a fantastic way to add calcium and other nutrients to your soil to nourish your plants. Veg such as tomatoes and peppers particularly like extra calcium!

  • To make eggshell plant pots, save half eggshells when cooking and rinse them out.
  • Remove the membrane, and then poke a small hole for drainage in the bottom using a needle.
  • Pop them back into an egg box once dry and fill with compost.
  • Add a few seeds to each one, press down lightly with your finger, and cover with more compost.
  • Water regularly and pop on a warm sunny windowsill.
  • Once your seedlings have grown and are ready to be planted outside, lightly crush the eggshell pot first to help it biodegrade once in the soil outside.
