Product Description

Product Description

Our experts are at it again! We believe wildflowers should be available to everyone, that’s why we created this mix for those who suffer from heavy clay soils and want to introduce wildflowers to these particularly problematic areas. Our Heavy Clay Soils mix is a blend specifically made up of deep rooting wildflowers that will hold their own in heavy clay soils and can also withstand drought conditions when clay soils dry up in hot weather. The accompanying grasses in this mix help to stabilise the structure of the wildflowers by creating a nursery for the annual and perennial flora to thrive in. This mix also provides a food source for bees and pollinators through its selection of RHS Plants for Pollinators wildflowers.

Aftercare

I’ve sown my wildflower seed in April / May (spring)

In August / September of the first year you have sown your wildflower seed, cut your wildflower sward to 7cm after flowering – you can do this by putting your mower on a high setting. In most cases remove clippings* (Note: a late spring sowing will result in late flowering). Do not be tempted fertilise or add top soil to this area – wildflowers prefer poor soil conditions, and this is how they should stay. Continue this same process, year after year. *If you have annual wildflowers in your mix and you do not wish them to return the following year, remove the clippings. If you want your wildflowers to return the following year - let them go to seed head, and manually assist their self-seeding by firming the seed heads into the soil. By doing this, your annuals will return the following year.

I’ve sown my wildflower seed in September / October (autumn)

In March / April of the first year of sowing your wildflower seed, make sure there is sufficient material to mow – your wildflowers / grasses should be at a height of 10cm. If your wildflowers are at this height, mow to 7cm no later than mid-April, as this will delay their blooming process. In August / September, after they have bloomed, cut your wildflower meadow again to 7cm, remove all clippings unless you want your annuals to return. If you wish for your annual wildflowers to make a reappearance the following spring, follow the process above by letting the seed heads drop into the soil, and give them a helping hand by firming them into the soil.
