Jack's Professional 25-5-15 High Performance Water-Soluble Fertilizer with Micronutrients for Heavy Feeding Plants in Continuous Liquid Feed Programs, 25lbs

Jack's fertilizer formulas are the most effective I've tried. I use them religiously, and my flowers reflect it! I have mounds of petunias that look like mine is the Proven Winners proving garden! I buy in large amounts because it saves me money for more flowers! I use Jack's, I recommend Jack's and I am addicted to the results!

I switched from the 'masterblend' to Jack's Pro 25-5-15 in my Hydroponics system for my lettuce and some pepper propagation. The Jack's Pro is a one Tbs / gallon solution and mixes very well. I have 27 Gal reservoir, so I mix the Pro in a Mason Jar and then add it in slowly so the plants can get used to it in a few days. If you have any questions and need help like I did, the professionals at Jack's is always willing to help and provide the right solutions. Email Jack's support, ask questions, make sure this is right for you. If you grow lettuce, this is it!

This stuff is outrageous. It works spectacularly on just about everything from Japanese Maples trees to vegetables to bamboo. One tablespoon per gallon.We have some neighbors behind us with a small urban farm that marvel at our squash growing in the front yard. Last year we had six plants that produced over eight hundred pounds in one season. When we use it on our timber bamboo we''ve seen 3 inch diameter shoots grow 18 inches in one day.We used to use miracle grow until we found out that they were putting poison in their bird feed. No more scott's for us. This stuff turned out to be a much better product. Highly recommended.

Just started using this...this growing season. Am using it in my drip system...weekly & also weekly, using it in fertilizing specific plants in my yard...hibiscus, Texas privet, palms, & nandina. So far....it appears that all the plants are doing well... I'll continue this schedule from ~ April through September. I'm cautious of how much of it I use...purposely trying not to "damage" the plants. I've probably errored on the "light" side...& will see after this season's growth, whether I can be more "aggressive" on the amount I use in the future. I live in Southern California area...

Great value and works well.

This stuff is legit. After watering, within 7-10 days noticeable green growth that continues. Only recommendation would be not to use full dose (1 tablespoon per gallon) when watering young, potted or recently planted plants.

It arrived quickly. Looks like good quality and expect good results . Disolves easily and has micronutrients as well

Works as advertised keeps deer off young fruit trees
