Planting, sowing wallflower
What you’ve got with this wallflower is a plant that will actually thrive where usually none of the other plants can grow.
When purchased in small pots, it is a good idea to plant in spring or in fall. Settling it down near a passing place is interesting since it releases a delightful fragrance.
- Select a very sunny spot.
- Water over the first weeks that follow the planting.
- No point in providing fertilizer, wallflower doesn’t need any.
Regarding any wallflower seeds you may want to sow, simply sow in a nursery starting from the month of March and transfer to the ground during the month of May.
Summer wallflower, for its part, requires sowing in February-March in a sheltered place. After that, you can transfer it to the growing bed in May for it to bloom in summer.
But you can also sow directly in the ground, especially ravenelle wallflower, once any risk of frost is set aside, from May to July.
- First of all, break the soil up with a couple strokes of the spade, and then broadcast seeds.
- Water regularly until seeds sprout and then as soon as the soil is dry.
- Thin to 12 inches (30 cm) when several leaves have appeared on each plant.
Pruning and caring for wallflower
No specific care is required, but, to boost flower-bearing, remove wilted flowers often.
If your wallflower starts spreading too far, simply pull a portion of it out – but don’t do this when seeds are about to fall or you’ll be sowing a trail of wallflowers behind you!
If slugs and/or snails wreck havoc, you’ll have to find a way to make them flee… just as you’ll have to deal with the caterpillars of that elegant white butterfly, Pieris brassicae (otherwise called the cabbage moth).
