Customer Reviews
I originally bought Jack's because it came in a larger size than what I usually buy, and for a better price. But I quickly became a fan, with vegetable plants receiving Jack's showing more vigorous growth and much better blossum and ultimately, vegetable production. And the veggies were huge! Jack's even let me sustain a few plants with good growth in a much less than optimum location. It dissloves quickly and is easy to use. Buying Jack's is now part of my Spring Start-Up regimen.
This product of Jack Peters is excellent for growing flowers and vegetables. It is much beter than the other products on the market. I've been using Peter's products since the 1960s even when it was not produced by the Peters family. I very glad Jack's Classic came along from the Peter's family. I had the opportunity to speak with Jack Peters at the Ohio OFA Trade Show in Columbus last July. Very informative discussion.
I have used Peters 20 20 20 for years. I was very happy to see it back. I really miss this product. It is great.
I have used water soluble fertilizers for over 30 years in my greenhouse operation and since retirement, I know use it at my home. I use a fertilizer injector and find Jack's water soluble dissolves easier and once dissolves, it stays in suspension.
Having moved to Florida in 2003, we found that dry fertilizer wasn't doing the job because of our climate, and dry seasons. Jacks goes on our flowers and bushes twice per month and we have had excellent results during the last 6 years of using this product.
