Vermicultie - 2 Litre Bag

Seed Germination

Vermiculite is ideal for the germination of seeds, because it's aeration properties combined with it's water holding capacity make it a very suitable medium for direct contact with the seeds.

When vermiculite is used alone, without compost, seedlings should be fed with a week fertiliser solution when the first true seeds appear.  Large seeds can be mixed with Vermiculite in a small polythene bag closed at the neck, and kept in a warm place until the seeds just start to germinate.  Then plant them singly in small pots or trays of potting compost.  Vermiculite can also be applied to the outdoor seed bed where it will give improved emergence and less risk of capping.

Potting Compost

Vermiculite in potting compost gives a very light open compost, holding more water and facilitating re-wetting, thereby lengthening the time between watering.  Vermiculite also has excellent ion exchange properties which absorb excess nutrients and release them slowly to the plants via the finest root hairs.

To improve an existing compost add 20-25% by volume of Vermiculite and mix thoroughly.
