How to Propagate Hostas Seed


The hosta is a shade-loving perennial plant grown in six sizes, from dwarf to giant. Flowers in pink, lavender and white and usually overlooked in favor of the plant's striking foliage. The hosta is also known as the plantain lily and hails originally from Japan, Korea and China. Growing hosta from seed is very easy.

Step 1

Soak the seeds in a mixture of one part household bleach and ten parts of water for three hours.

Step 2

Pour the seed-starting mix into the tray and press down so that it is level and the surface is 3/4 inch from the top of the flat. Water the soil well and allow it to drain before sowing the seeds.

Step 3

Scatter the hosta seeds on top of the soil. Cover them with a very thin layer of dry planting mix.

Step 4

Mist the entire surface of the seed-starting tray with water until it is thoroughly soaked.

Step 5

Open the bag and insert the tray. Seal the bag and place it in an area that remains at 70 to 80 degrees F. The seeds should start sprouting within 10 days. Depending on the variety of hosta seed, germination could take considerably longer.

Step 6

Remove the tray from the plastic bag and place it under shop lights or fluorescent lights after the seeds begin to germinate.

Step 7

Transplant the hostas into planting pots when they have two sets of leaves.
