How to Start It
★ Recommended for beginners
In early spring, when the new shoots are just poking up, dig up the whole clump and cut it into pieces with a sharp spade or knife, each with a few shoots and plenty of roots. Replant the pieces at the same depth, 60 cm apart, and water them well. Each piece grows into a full plant within a few years.
Hostas are tough, long-lived plants grown for their big, bold leaves, and they light up the shady corners where little else grows. Many people have one they can split into several free plants. Their one big enemy is slugs, so plan for them before the leaves unroll.
When To Start
Hosta needs warmth. Wait until your last frost has passed and the soil has warmed before sowing.

Planting & Sprouting
Growing Tips
- 1Plant hostas in shade or part shade, since hot afternoon sun scorches most types, though gold-leaved ones take a little more sun.
- 2Mix compost into the soil at planting so it holds moisture.
- 3Water deeply each week in dry weather, because the leaf edges turn brown when the soil dries out.
- 4Spread a layer of compost or mulch around the plants each spring to feed the soil and keep it moist.
- 5Go out with a flashlight in the evening to pick slugs off by hand, and choose thick-leaved varieties, which slugs damage far less.
- 6Hostas are toxic to cats and dogs, so keep chewing pets away.

Harvesting
When to Pick
Grown for foliage all season; tall lilac flower spikes appear in summer
How to Harvest
- 1Cut off torn or yellow leaves through the season to keep the plant looking fresh.
- 2Snip off the flower stalks after the flowers fade, or before they open if you prefer just the leaves.
- 3After frost flattens the leaves in fall, clear them away, which removes slug eggs and keeps things tidy for spring.
- 4Divide crowded clumps every few years in early spring to make new plants.
