General Growing Tips:

If you are growing root vegetables from seed, make sure you follow these 4 simple steps:

  1. - Use a dibber to create rows before sowing your seeds.
  2. - Gently cover seeds with a fine layer of compost using a compost sieve.
  3. - Firm and level compost with a tamper. This will ensure even germination and remove air pockets.
  4. - Evenly water compost using a watering can with a rose until the compost is moist but not saturated.

 

If you are growing from plant or have already started seedlings in a Vitopod Heated Propagator, follow these steps to ensure plants are safely transplanted into your Quadgrow Root Veg Planter.

  1. - Make a hole in the compost large enough for your plant.
  2. - Place your plant into the compost. Firm compost down gently around the plant.
  3. - Water compost using a watering can with a rose until the compost is moist but not saturated.
