step by Step
Your wallflowers will be sold in ta y bunches of leafy roots – ‘in the green’ – with brown paper or newspaper wrapped round the roots to protect them. Unpack and ensure they look healthy and relatively moist.
Soak in water for at least an hour before planting to make sure roots are fully hydrated and not dry. Sat in a garden centre or post office for days may mean they’re not at their best for planting straight away.
Dig holes big enough to fit the root mass, and plant in clumps quite closely together to stop there being a ‘gappy’ look to your planting, though leave room for a bushy plant to develop. Firm the soil in well around the crown.
Water in well and mulch with gravel to keep weeds down, and for a neat effect. During hot spells, mulch with woodchip to retain moisture but give no extra unnecessary nutrients. This will also keep roots warm in winter.
