Vermiculite – 10L Gro-Sure

Gro-Sure Vermiculite is ideal for growing from seed and to help both indoor and outdoor plants. Vermiculite helps to absorb nutrients, preventing them from being washed out as well as releases them as required to plant roots. Vermiculite is a naturally occurring, non-toxic material heated to a high temperature to produce a lightweight material with a high surface area. 

• Lightweight 
• Helps to retain moisture and nutrients
• Provides insulation for healthy seed germination

Vermiculite is a naturally forming mineral that is extracted from mines. The natural laminar structure allows the material to expand up to 30 times its own size during heating. Its natural shape once heated gives excellent insulation, drainage and aeration properties. 

How To Use

Seed Sowing 

• When sowing seeds always follow directions on the seed packet
• Seeds of all sizes can be raised in just Gro-Sure Vermiculite 
• Alternatively, seeds can be raised in a 50:50 mix of Gro-Sure Seed & Cutting Compost and Gro-Sure Vermiculite. This is particularly beneficial for very small seeds. Sow seeds thinly and evenly, making sure they are not too deep in the compost. Cover seed trays with a thin layer of Vermiculite and gently moisten. Avoid over-firming. 

Pricking Out

• When seedlings are large enough to handle, remove from seed trays with a dibber or pencil
• Plant in Gro-Sure Seed & Cutting Compost or with a mixture of this compost with 25% to 30% of Gro-Sure Vermiculite 

Potting On

• Use a mix of All Purpose Compost and 25% to 30% Vermiculite. This creates a light and very open structure enabling compost to absorb and retain moisture for easier re-wetting.
• Before transplanting plants from pots to containers it is recommended to water the plant well and allow to drain. Remove plants from their pots and place into the container, firming compost around the plant roots. Once the container is fully planted, water well and feed as appropriate.
