  • Fertilizer Worth Fertilizing With

The media could not be loaded. Great product that’s keeping my plants healthy. Good value for the money.

  • Good Stuff! (But it Stinks like Poo Big Time)!
Size: 4 lbs
My plants in a vertical Green Stalk garden system love it. Learned to use it only in each pocket and just a smidge. Green Stalks have a watering cap - do not use dry powder in that. Use only the liquid version of this product if you want to nourish from above. For the GS I would say use the liquid. For my conainer garden, this is good. Many varieties. Major Downside is that it waaay smells of poo and once watered in the poo smell lasts for days. Very pungeant! ... show more

  • An Excellent Fertilizer
Size: 4 lbs
The media could not be loaded. I bought this in the spring after I planted my vegetable garden in the ground. The tomato plants and zucchini were somewhat yellow. Within a week of sprinkling this Fertilizer onto the soil, the plants became green and healthy. I apply it once a month to all my vegetables and this has been my most successful and healthy garden ever. I'm very pleased with this product. It's easy to use and you get a lot for your money. I have used about a half bag this year. That is about all I needed. It doesn't smell good but it's a lose and easy to spread, dry Fertilizer. ... show more

  • Not exactly what I expected but...
Size: 4 lbs
I've grown so accustomed to having fertilizers that mix in water easily. This is not like that. The product is kind of hard to keep in suspension while you use it and you wind up with a lot of gritty residue at the bottom that you need to add more water to. However, there's no chance of burning the plant at all. On one container plant, (Hydrangea) I poured out & left the gritty, bone-meal like residue all over the top of the soil and I used more than was called for but the plant has never looked better and is blooming more and larger blooms than in previous years. Even the indoor plants whose pots are set in decorative planters with no drainage, (just activated charcoal beneath them) look better than ever. I will buy this product again. ... show more

  • Best Soil
Size: 4 lbs
I highly recommend this soil for your growing plants and is best mixed with HAPPY FROG potting soil in the brown bags. Both have everything your garden plants need for growing good healthy fruits, vegetables, whatever you're growing. The best deal is buying 4 bag's at a time, which saves money. Buying 1 bag at a time is too costly. So I recommend 4 bag's at a time, price is good and that makes it easier for me. ... show more
