A good rule of thumb for planting and care of Hosta’s is the lighter their foliage, the more sunlight they can tolerate. The varieties with deeper darker foliage retain their colour best in moderate shade. The variegated varieties prefer more sunlight to keep their white and gold stripes. All Hosta’s need some shade and few, if any, will do well in strong direct sunlight all day. Plant them in rich organic soil with good drainage and keep the roots moist. One common difficulty in Hosta care is slugs, which leave unsightly holes in the leaves. A light scattering of sand and broken eggshells around your plants will help keep those slugs at bay!
As a rough guide when planting Hosta as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
How to grow Hosta
Position: Partial shade
Soil and site: Fertile, moisture retaining & well drained
Flowering time: Late Spring through to mid-late Summer
Growth rate: Moderate
Ultimate height and spread: Clump forming, so width will grow over time. Height 20cm to 75cm depending on the variety
Hardiness: Hardy once established
Aftercare: Water well until established, avoiding soil becoming waterlogged. Divide clumps in early Spring or late Autumn if they become congested (usually every 3-5 years). Keep an eye for slugs in Spring as the new leaves emerge – they are a favourite for them!
