Calcium is a component of plant cell walls, and it’s needed for enzyme formation and nitrate uptake. Organic calcium can also be used to help neutralize excessively acidic soils, which is especially important when you’re growing green, leafy vegetables like lettuce and spinach, or cruciferous vegetables like cabbage, broccoli, cauliflower, and kale.

Highest quality ingredients help provide an effective and environmentally friendly approach to plant care, crop fertilization and soil management.

Most delicious and productive radish that I have ever grown!

Thank you for providing this seed! These radishes were the best I've ever grown with respect to taste and productivity. So good. So easy. Will always make a place for these beauties! (Excellent roasted and tossed with butter!) I just ordered more!

First time growing turnips

These were fast to mature and really tasty. I am new to gardening and didn’t thin my seedlings well enough so many of them did not produce much of a root but that’s okay because we definitely got to use the greens! Photos are of the turnips from the garden to my kitchen and the dish we made with them. Some turnips in the photo are not the purple top variety but overall I think the purple top got larger than the others I planted.

First time growing Mustard greens

This was the first time I have grown greens of any kind and it was a success! The plants are beautiful with the purple veins. I over crowded my raised bed with these accidentally but they still did really well. I started seeds indoors and had a hard time germinating (due to my own fault being new to seed starting) but still planted what I had outside when the time came. I was surprised when I saw the seeds that didn’t germinate indoors started coming up shortly after being outdoors. That’s how I ended up overcrowding my raised bed but on the plus side I now have a ton of healthy great tasting food in my backyard. Photos are of the greens from my garden to my kitchen.

Beautiful addition to any garden!

This is my favorite plant in my garden right now. I started my seeds last winter (2022) and planted in spring 2023. My mullein survived the insane high temperatures over summer and was a refreshing pop of green all winter. I am eagerly awaiting the flower!

Im like a kid at Christmas

These are so much fun. They sell out fast and I try to get at least 1 every year. Last year I was lucky enough to grab 2. I love trying new things and these are a mixture of flower, herbs, and vegetable. One of my favorite carrots came from here. It’s one of three that I grow every year because it’s fun!
