1. Put some soil in your glass jar. It should take up about 1/3 of the jar height.
2. With a small stick, make a small hole in the centre of the soil and place your seedling in. Gently pat down the soil with the stick.
3. Give your seed/seedling some water. The soil should be damp but not soaked.
4. Put the lid on the jar and place it in a semi-sunny spot. Remember to give it some water every couple of days
