Seeds are In-Stock
We are fully stocked with a wide variety of seeds. Wholesalers and retailers are running out of seeds, so stock up early.
We have been stocking Botanical Interests since we opened. I have personally used them for 25 years. They are a Colorado based, family owned business. All of their seeds are non-GMO, with many OMRI seeds. Their packets are like a little encyclopedia’s with all kinds of interesting facts about the plant.
New Seed Supplier
We were lucky to find J & D Heirloom Seeds this season. They filled in the gap in our seed collection. We look forward to doing even more business with them in the future.
This is the first year we are trying winter sowing. Winter-Sowing is an outdoor method of seed germination. You just need two things, miniature greenhouses and Mother Nature. You can make a greenhouse from any clear or translucent plastic container. Gallon jugs, take out containers, 2 liter soda bottles, or even baggies.
Now you need to put holes in the bottom. We used a drill but you can use a hot glue gun or boxcutter.
Then partially fill the container with soil. We used a combination of Black Gold Seedling Mix and Compost. We also added Roots 1-step, which is a blend of mycorrhizae and beneficial bacteria. This will allow the plants to better acquiesce nutrients. Thoroughly water the soil.
The next step is to seal the container.
Make sure the top lid is not on so the plants get air. Then put your container outside into the elements. We are leaving ours in an unheated greenhouse to protect them from strong winds.
