Hostas are a garden favourites for this time of year.Hostas are most loved for their pretty, variegated, pleated or plain leaves.
Hostas are useful, low growing understorey plants that flourish in the dappled shade of trees. They prefer morning sun and protection from the afternoon sun in a not-too-hot climate with soil that stays moist most of the time. Hot sun and dry periods will spoil the plants and just make them look miserable.
In most areas hostas will die back in winter and re-shoot new leaves from the base in spring. This is the time to be on the alert for snail attack. Snails and slugs are the number one enemy for hostas. There’s something about hosta leaves that these pests find irresistibly attractive and it’s very common to see their leaves peppered with snail holes. Once the holes are there, the leaves are spoilt. There’s no cure, only prevention. Potted hostas can be surrounded by a thin layer of sand to deter munching molluscs. Blitzem or Baysol pellets can be sprinkled around the plants. Make sure that the pellets are replaced after heavy rain periods and, if you have pets, use Blitzem Snail & Slug Granules.
In the warmer months hostas produce flower spikes topped with bell-like blooms. While these are pretty, most gardeners grow hostas for their leaves, rather than the blooms. Divide crowded clumps in early spring and feed regularly with a general liquid fertiliser like Thrive Flower & Fruit or Nitrosol while the plants are growing.
