Hosta's do require a cold treatment prior to sowing, and prefer to germinate in mild conditions. We do not recommend you direct sow them into your garden but instead start them in pots inside your home. Once they are about 2" tall you can transplant them into your garden.

Please note that Hosta seeds are not uniform in size and you should treat all pieces and parts of seeds and viable seeds. The germination rate will be lower than most other annual flowers seeds and should be around 50%.

To cold treat add your packet of seeds to 1/4 cup of peat, or seed starting potting soil, and place in a baggie or tupperware type container. Add 1 tablespoon of water and gently mix. Place your baggie or container in the fridge (not your freezer) for 30 days. This breaks the dormancy of the seeds and tells them it is time to germinate.

After the 30 day cold treatment sow your seeds on the surface of your pot that contains some pre-moistened potting material. Very lightly cover with your peat or potting mix as they do prefer some light to germinate, but at the same time want to be partially covered. We sow these in pots that have holes in the bottom (like a 4" landscape pot) and then place this pot in a about 1/2" of water as you do not want to let the seeds try out. When then lightly cover our pot with plastic wrap to keep our seed bed moist.

Keep cool, in an environment inside your house, and do not let your seeds be exposed to temperatures above 75 degrees. Once germination occurs you can remove the plastic wrap but keep watering from the bottom of your pot. Letting your Hosta seedling soil dry out at this stage will guarantee certain failure.

Once your seedling is about 2" tall you can transplant into a larger pot. Slowly introduce to the outdoors and once established you can introduce into a shady area of your garden. Here in zone 7 once Hosta's mature they tolerate summer heat in the mid-90s and sub zero winter weather. Hosta's do not do well in extended hot summer weather and they are not advised for zones 9-10.
