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.

My Plants Love It
This is my go-to for my houseplants. It's more expensive than some but my plants love it. It was recommended by the garden enter I go to.

Good stuff for plants
Jack’s plant products are well made. I use both the Orchid and Blossom Booster as well. My huge rubber tree needed some fertilizer and it was suggested that I try Jack’s houseplant food. Easy to mix. A bit pricey for the small container but if it keeps my indoor plants healthy it’s worth it!
