Growing hosta seed is a fun hobby
Growing hosta from seed is fun too do.
Many people grow hosta seed during the winter months under lights or start them in the garden in the springtime.
It is very nice to be able to see some green growing when it is cold outdoors.
If you have questions on how to get started or a question about growing seeds please stop at the Forum and ask your question and I am sure we can help you out.
                     How I grow hosta seed
Let me start by saying that hosta seeds do not grow up looking like the pod parent they came from.
They may carry some of the gene’s or traits of the parents though.
About 99% of the time the only way to get variegated seedlings is to plant seeds from a streaked pod parent but one never knows what to expect for sure.
There are many different opinions or ways to grow hosta seeds.
This is the way that works for me, after growing a year or two you will find what works for you. So give it a try and enjoy seeing the green in the middle of winter.
I start with a good soilless grower’s mix. 
Now I put my potting mix into a large bag (I use 4 gallon Zip-Lock Bags) then I put in enough water to moisten the mix. Next I use a standard tray (10 1/2” X 21”) that will hold 12 inserts (3 1/4” X 51/4”) I fill the inserts ¾ full of the moistened soil less mix.
I sprinkle the seed on top of the soil and cover them very lightly with some of the mix making sure the seed’s are in contact with the soil. I have found that I will use twice as many seeds as I would normally use as the hosta seed do not always germinate at a high rate. I find this vwill very year to year and plant to plant. Remember to mark your planted seeds and mist lightly with water before putting the tray into a large sealed baggie or sometimes I use the plastic tray covers. At this point the seeds do not need light to germinate; I put them on a heat mat for a week to ten days which is a good guess as to the time they need to germinate. Aout 78 degrees works good for me, it seems like germination time can very a bit for some seed varieties. After the seed germinates I move them under lights. I use regular 4’ shop light fixtures with the cheap bulbs as well as cool temp bulbs. I put the lights within an inch or two of the top of the tray. I leave them this way until the 3 or 4 leaf stage. If I need to water, I only water from below. Many folks transplant at the two leaf stage, it does help the seedlings to grow faster if you do transplant them more often. Remember if you do transplant more often you will need to use more of your growing space under the lights for the larger pots. At this stage I remove the cover and place the lights 2 or 3 inches above the seedlings in the trays. I will only bottom water at this point and will use a very weak fertilizer every other time that I water. Miracle Grow Tomato fertilizer seems to work well for hosta seedlings.
Remember this is what works for me; some other ways work for others so ask around most hosta folks will share their ideas with you. I hope you have fun with this hobby and if you have any questions just send us a e-mail. Contact Us
