Very healthy plant food
I’ve been using this houseplant fertilizer for a couple of months now and my plants look amazing. I really like this food and respond very well.

Great fertilizer!
I have been using a blue fertilizer for many years and then I couldn't find it anymore. I don't think this is the same brand but it works just as well. I put about a quarter of a teaspoon in my water and water with the fertilizer every other watering. My plants are beautiful! It also comes with a little measuring cup and chart which is very useful. So glad I found this!!!

Jack’s keeps my plants happy and growing
I’ve tried other fertilizers for my houseplants in the past but always come back to Jack’s. In the summer I use it every watering indoors and every other for the ones that sit outside for the summer. I use 2 gal jugs and cans and add one tablespoon each. I pull back to once a month or so in the cold months. You get a ton and it goes a long way. Great value. My plants grow so much with Jack’s. Sometimes I run out and don’t rush to replenish. I am always surprised when I start back using it and see the difference. I don’t usually have issues with burns, but I am as careful as I can be to avoid getting it on the leaves, especially if they’re in sunlight while watering.

Seems to
So this item I believe is a bit hard to write a review for simply because, how do u know it would go without using this , SO I am comparing past summers with my outdoor baskets. I can say that I use this every time I water my indoor and outdoor plants this past summer. I can say that so far we have had a hotter than normal summer BUT my baskets seem to be thriving. This stuff DOES smell pretty strong in the container lol forewarned but I suppose that’s to be expected with any fertilizer that should be working!

Love Jack's fertilizers
I used to use Peter's plant foods so now I use Jack's (one in the same). I have had excellent response from them, especially the bloom food. I use several products and highly recommend them all.
