Any of these worth giving a try?

Most of us with the EZ-Flo love it, but that price is high. The rest of them are better done with home-made products or off-the-shelf stuff you can get locally.

Liquid lawn fertilizers are seldom organic. Also they go on at such a diluted rate you have to reapply every 2 weeks. The soil boosters are likely to be molasses, kelp, and humates with some possible soap in there to help it soak in. The fertigator is outrageously priced. The Siphonex never sells for more than $20. Only difference is the Siphonex does not come with a bucket.
