Perennials can be purchased from early spring until autumn. You can plant perennials purchased in pots in a garden at any time of year as long as temperatures are above freezing but the best times to plant them in a border are in the spring or autumn. It’s not difficult. Planting perennials can be done in five steps:
- At the place where the perennial will be planted, use a trowel to make a generously sized planting hole.
- Remove the perennial from its cultivation pot and carefully tease a few of the roots free from the rootball.
- Now plant it in the hole so that the top of the rootball is at the same level of the soil as it was in the cultivation pot.
- Fill the planting hole with soil and tamp down firmly all the way around the plant.
- Then give the plant plenty of water.
Tip: Plant them at the right distance apart. For smaller plants, this is usually around 20-25 cm apart; for larger plants, this is about 50 cm apart.
