  • Good starter fertilizer
Size: 32oz
Needed an initial fertilizer for my raised bed tomato’s and peppers. Nothing overpowering as I was using natural materials and compost to help seedlings get transition to their permanant homes. This stuff did great getting roots set and leaves growing.

  • Best tomato producing product.
Size: 8oz
This stuff is amazing. It works 100% better than any MiracleGro product I have ever used. My tomatoes plants began to produce 2 days after watering with the Tomato Booster. Every time I use it my vines, that aren't producing, begin to produce several new tomatoes within a day or two. Definitely worth the price. ... show more

  • Best tomato plants I ever grown
Size: 128oz
Super looking green leaves. They are fruiting like crazy. This is the best crop of tomatoes I have ever grown. I started growing them indoor by seed. I transplanted the day after Mother’s Day in zone 5b. And now they are almost seven foot tall. There will be lots of canning and give away this year. It’s my new #1 fertilizer ... show more

  • So amazing, I definitely recommend!!!
Size: 32oz
This is making such a difference for my tomato plant. I feed them once a week, and they are growing like crazy and bearing tomatoes like crazy. I can't wait to taste my first one. Compared to last year, when I barely had enough to fill a bowl, this year I'm going to have a bumper crop

  • I use this weekly and love it
Size: 32oz
I use this weekly during the flower-and-fruit stage of my tomatoes, squash and peppers. I apply it by hand using a watering can for plants that otherwise are irrigated with a drip line. I use it as a soil drench and as a foliar spray if a plant needs a little help. I like the amount of fertilizer I get using the standard application rates recommended. Seems very cost effective. It’s clearly effective for tomatoes and squash. I am still assessing it with peppers… ... show more

  • Unsure of the problems

I haven’t gotten one tomato this year but I don’t know if the problem is the boost or weather
