Vermiculite, ideal for growing seedlings
You want to grow seedlings and give them a good start, how do you do that? Seeds and seedlings are fragile and grow best in a controlled environment. One of the biggest challenges we had, when we started growing our own plants from seeds, was watering too much or too little. If you give too much water your plants will rot and develop all kinds of fungi on the surface but if you give too little water your seedlings will not get enough nutrition and will grow sluggishly. The solution to this is to add vermiculite to the soil.

Vermiculite helps to distribute water gradually. Because of its strong absorption power, it first sucks up a lot of water and nutrients. As soon as the surrounding soil begins to dry out, the vermiculite slowly releases the water and nutrients.
This ensures a long-lasting good balance in your seed trays so you don’t have to sit on top of them to make sure things don’t go wrong and you can spend more time in the garden!

The best ratio for seeding is 1 part vermiculite to 3 parts potting soil. This will make your soil a lot lighter and airier.
