Planting & Care
Planting & Care
Soil and Water: Brussels sprouts require fertile soil high in organic matter and nitrogen. They perform best with a pH of 6.5 and consistent moisture.
Planting and Growing: Best grown as a fall crop, start seeds indoors in June to set out transplants about 100 days before the first frost. Sow in flats and set out plants when then have 4-5 true leaves. When the lower sprouts are about 1 inch in diameter, remove the top most growing tip of the plant. This will allow the top sprouts to develop.
Harvesting and Storage: Allow the plants to be exposed to a frost, this will improve the flavor of the sprouts. Pick the sprouts when they are about an1-2 in size. The lowermost sprouts mature first.

Let customers speak for us
Working great
I bought these seeds to go in bundles of packets of vegetable seeds that I will put in the Blessing Box at a church here in town about late January so people who need to can supplement the groceries they buy with a garden. I'm sure they will love them. If my budget stretches that far, I will get some for myself and let you know how I like them. I still have eight bundles worth of packets of seeds to purchase for them first, though.
Appreciate that you have this in bulk quantities. We use this as a rooting hormone and as a potting mix and soil supplement. Kelp meal is rich in minerals and micro-nutrients and contains growth hormones that support healthy root growth.

I grow flats of this for my pet pigs, because of the high nutritional content. They love it. I find them waiting at the growing location every afternoon waiting for their fave. I've grown beautiful flats of pea sprouts and alfalfa for them too, but they turn up their snouts and walk away.
