Really helped my greens
5 Stars
Really helped my greens
I ended up getting a bigger container because I also have a couple raised garden beds. I didn't mix this into the soil when potting everything because this was my first time gardening (yay trial and errors of learning!). But I added it around the base of each plant about 2 inch deep (just sprinkled it around). I also mixed it around the rest of the soil in the fabric pot since I planted some chives after. As you can see, the plants after a few weeks are really loving this stuff.All in all: Worth the money and a good buy. Smells a little like day old fish when opened but hey that's not a bad thing. It goes away once planted.Next time I'll be adding it directly into the soil mixture especially when I transplant my tomatoes :)
