Hosta Sum and Substance

Hostas are planted in spring or autumn. Hostas thrive in deep, rich, humus-bearing, loose soil, preferably neutral to acidic (at least low in limestone), and moist to wet throughout the year. Plant them in partial shade or dappled shade and in a sheltered position away from strong winds.

Prepare a planting hole of 20 cm (8in) x 20 cm (8in) x 20 cm (8in). If your soil is heavy, mix equal parts of compost with crumbled soil, partially backfill the hole, and place your potted plant in a way that the top of the root ball is covered with 3 cm (1in) of soil. Adding a slow-release fertilizer (dehydrated blood and bone) will nourish your plant during its rooting period without the risk of burning. Make sure to position the collar well above ground level. Firm the soil and water generously to eliminate air pockets. If the weather is dry, regular watering for a few weeks will facilitate your plant's establishment. Also, water regularly during dry summers.

With their shared preference for moist locations, slugs and snails never stay far away from hostas. Even though blue or variegated hostas often have thicker and tougher foliage, which is less appetizing to slugs, these plants still need protection from gastropods. Protect your Hostas by surrounding them with ferramol-based pellets (approved for Organic Agriculture), eggshells, coffee grounds, wood chips, or any dry and rough natural substance that repels them. Hedgehogs are the gardener's best allies in the fight against gastropods, as they do not disturb the soil like hens and do not attack the lush green shoots of young plants. Finally, some plants have a repulsive smell to slugs, such as wormwood and garlic.
