Hostas can be grown from seed harvested from dried seed heads in the autumn. Sow in small seed compost pots in the spring and place in a cold frame. Plant seedlings in individual pots and continue to grow them. Seeds from variegated plants will usually not come true (be the same), and plants grown from seed will be only one color.
When should I plant hosta seeds?
Hosta seeds germinate well in normal house circumstances, with temperatures ranging from 60 to 70 degrees Fahrenheit. Use a “peaty” starter mix and a light layer of peat moss to cover the seed. Until the seed germinates, keep it moist but not soaked. Sow seeds 8-10 weeks before the end of the frost season. Keeping the plant hydrated throughout the summer months is an important part of hosta care. They typically require 1 inch of water per week.

Are hostas bulbs or seeds?
Hostas are all hybrids, which means they are the offspring of at least two separate plants with diverse genomes. Multiple genetic parents are common in hostas. Hostas can also self-seed, resulting in a “selfed” hybrid, according to the Delaware Valley Hosta Society’s “Hosta Lingo” page.
Can you start hostas indoors?
Hostas are a leafy, shade-loving perennial with rich foliage and beautiful flowers that will impress any client. Hostas are ideal for indoor plant arrangements due to a variety of qualities. The foliage, which is their most beautiful feature, will lend depth to any plant arrangement. Hostas are a plant family comprised of several species and cultivars that come in a wide range of color, size, and shape, making it simple to select the right match for any plant arrangement. Hostas grow nicely in containers and don’t require direct sunlight, so they can be grown indoors.
Can you grow hostas in ericaceous compost?
Hostas want a neutral to acidic soil that is rich and well drained, as do most perennial plants. Plant them in multi-purpose compost or a blend of compost and good garden soil to give them the greatest start. Some organic composts, like John Innes, are quite fine and can become waterlogged in the winter. So, especially for young hostas, we make our own compost. To make a rough compost, we combine two-thirds compost with a third other materials in a large (40 gallon) trug. Mini bark chippings, composted bark, or even pea gravel and pebbles can be used. Add a handful of slow-release fertilizer pellets to the mix.
