I bought these two seasons ago. The first year I only grew a few, just dug a hole and transplanted my starts. All of them did well even though I honestly neglected them. Grew to about ten feet. This year I started maybe 40. All but 2 sprouted into very healthy plants! I prepared a place for 18 plants, transplanted them(they transplanted well just don't let them outgrow their container or it will stunt their growth) into manuer compost and made sure to water them well in dry spells. All but two grew into huge 12 foot tall plants and the other 2 must have reached 14 feet! Very healthy. All gave me a huge amount of large seeds that taste great. I plan to plant about a hundred plants this spring. Can't wait to see those beautiful giant yellow flowers again! Made a big impression on people. My grandpa snuck over and cut one right out of my garden because he wanted to put it next to his Mailbox! I was slightly offended but at least I know he was impressed. Highly reccomend.
Excited with this product...90% germination so far.
Looking forward to these sunflowers against our fence behind our raised beds. Fun for the kids and the birds love them - keeps the birds a little busier so they’ll keep out of other parts of the garden! As always, high quality seeds.

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.
Helps me keep the ants down on my property. Place outside and keeps ants down even in your house.
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.
