When To Sow

Spring or Autumn. Keep an eye on the weather, avoid sowing around the time of frost or drought.

Sowing Rate
See individual product page for sowing rate. Increasing this rate may result in some species out competing others and reducing the rate may result in weeds or grasses dominating. *Tip 1 level teaspoon of wildflower seed is about 1.5g

Flowering Period
Annual species sown in Spring will bloom 8-10 weeks after sowing. Annuals sown in Autumn will bloom the following summer. Perennial species begin to flower the second year after sowing. If managed correctly, these flowers will return year after year.

Ground Preparation
Prepare pots or a bare seedbed in advance of sowing, free of weeds, grass, and other plants so that the wildflower seeds don't have to compete with other plants. This step is essential to establish wildflowers successfully.

Sowing

Lightly dig over and rake the soil to create a fine, firm seedbed.
Shake seed packet and mix the seeds with a carrier if using and scatter over the seedbed.
Lightly rake, roll or walk over the area to create good seed to soil contact. The aim is to push the seeds into the soil rather than to bury them too deep.
Water lightly and take care not to wash the seeds away.

Maintenance
Cut the plants back to 7cm in height after flowering in the autumn. Remove the cuttings to keep soil fertility low and to not smother emerging plants. Do not apply fertiliser or plant food.

This Seed Contains No Filler
Mix with a Carrier such as sand, sterile compost or Ready Brek to bulk the seed for a more even broadcast.
