Saving seeds
Saving seeds
In growing a garden year after year, I find that I have accumulated many packages of garden seeds. Going through the inventory, I realized that some of my saved seeds go back as far as 1999. Knowing that seeds don’t last forever, (well at least most seeds) I decided to check out the viability age for some garden seeds. If they’re too old the percentage of germination will be much lower and saving your seeds was a waste of time.
The chart below gives us the average viability age of seeds stored under “proper conditions” which means that seeds should be kept in a cool, dark place with even temperature and humidity. Store seeds in a small mason jar,vacumn seal bags or air tight plastic bag with a silica gel packet . If you don’t have silica gel use dry powdered milk wrapped in a coffee filter.
For long term storage, seeds can also be saved in the refrigerator or freezer. Refrigerated seeds proved to be 10 times more viable than seeds stored at room temperature. Frozen seeds have even a longer lifespan as long as their moisture level is below 8 percent before freezing. This can be done by placing the seeds in a mason jar with 1/2 lb of silica gel for a week. Once the gel turns from dark blue to a pink color and when the dried seed breaks instead of bends when folded, then they are dry enough to freeze. Quickly, transfer the dried seeds to another container and freeze to save for future use.

If you are saving your own seeds, be sure your seeds are totally dry before storing and label each packet with a name, date and any other comments for next year. Unlike open pollinated seeds, seeds from F1 hybrids will not be true to the original plant .

When your lily has blossomed, and the seed pods have formed; do you harvest the seeds and put them in the freezer untill spring(?) or just plant them where you would like to see new plants next year? Does either or neither of these work? Thank You.
I love this site. Would you tell me how to save Black eyed Susan seeds from dried pods and how and when to replant them around the main plant I already have outdoors, I am trying to fill in spaces in the circle of them I have around my well cap… thanks again for your help…
My Mom has beautiful poppies in her garden – what is the best way to get the seeds so I can plant my own for next year? I need step-by-step instructions as my Mom and I do not agree on how we go about this.
I want to save seeds from summer flowers such as Morning Glories, Hollyhocks, etc. How and when do you do this? Thank you, Pam & Donna
I need to know when and how to harvest trumpet vine pods. Also, I need to know how to plant them. What and how to store them for the New England winter.

I have a black current swirl datura that has bloomed very well this summer, but now the lower leaves are turning yellow. I put Miracle Gro timed released plant food on it in April or May. Should I add more now? Also, there are several seed pods on it. How and when do I collect the seeds? It is growing in a container, partly shaded, on my patio.

Are the seeds of a Japanese Lantern (Jack-O-Lantern ) plant found inside of the delicate orange flower of what looks like an orange cherry tomato? If so – the seeds are so tiny�what is the best way of drying them out? I would love to know more about this plant! Thank you.
Where are the seeds on the following plants?
Astilbe
Lady’s Mantle
Burning Bush
Globe Thistle
Aster ( New England)
Butterfly Bush
Beauty Berry
I collect every seed that I can identify and those above have eluded me for years.
Also is there a site on the Internet that shows pictures of seed pods and the seeds themselves of both perennials and annuals?
Thanks for your help. This is my first time at this site and I LOVE it!

Aster- cut the ripened flowerhead and place in a paper bag. Once dried shake the bag to release the seeds. Separate the chaff from the seeds.
Globe thistle – Hang the flowerhead upside down in a bag and let the seeds fall out or shake the bag to release seeds.
Thank you so much for your site and information! I have always appreciated the hard work gardeners put into thier beautiful havens. I am now wanting to try my hand at this much loved source of beauty. My question how and what do you harvest from the Beauty Berry, we live in TN and it now has the beautiful purples beads on it??
