Hosta Care
Planting
Put this plant into an organic soil – or one enriched with peat moss. This is a woodland plant and it loves a rich soil full of organic matter and natural nutrients. It loves regular and deep waterings as well. If it's happy, the amount of time you'll spend on hosta care will go down.
Plant so the crowns/eyes of the plant are just below or just “at” the soil line. Do not cover these eyes with a great deal of soil as they are the growing points for new leaves.
Best Growing Conditions
Hosta grow best in part-shade to shade. Yes, I know that some gardeners put them in the sun but watch the leaves on those plants as they fade away during the summer heat when compared to the leaves of plants that are happily sitting in the shade.
Pruning
Prune this plant only in the fall after frost has whacked it back. No other pruning is needed or desired (other than deadheading – see below)
Deadheading
The spent flowers can be deadheaded – the stems can be cut off as far down into the foliage as you can reach – immediately after they have finished blooming.
You can allow the seed to mature and self-sow. You’ll get new baby plants but understand they will not come true from seed and rarely look like the hybrid mother plant.
Wintering
Hosta are usually hardy into USDA zone 3. This is one tough plant but it does not appreciate late frosts. If your plant has thrown new leaves and these are frosted, it will be distinctly unhappy about producing more (if a brand new plant installed too early in the spring, you may lose the plant at this point). If the plant is established and in good shape, it will unhappily produce more leaves but often not as thick as the first set. I note that most hosta only throw one set of leaves a season so if you damage them or allow them to be slug-food, what you see – is what you get and no amount of hosta care will help you out here.
Pests
The major pest of hosta are slugs. These can be controlled by dusting diatomaceous earth around the plants or obtaining a bait containing iron phosphate.
Diatomaceous earth is a natural product – it is the leftover skeleton of dead sea-creatures (diatoms) and the shells are tiny and razor-sharp if you’re a slug. If you’re a human, the microscopic particles feel like talcum powder, harmless to pets and humans.
Iron phosphate is a particularly lethal compound for slugs (but they love to eat it) that is totally non-toxic to pets, children or adults. It is a naturally occurring compound in soils.
