    This stuff works great! I used it two years ago on my crops and last year I didn’t use it, just to see the difference in production. I had significant better production from my plants the year I did use it. Will definitely be using it from now on.

    I started my raised beds last year and decided mid season to try trifecta. Once I placed your product as you instructed in your video I watched my plants soar!!! They looked healthier as well as production picked up. I already placed 2 orders this season as I want to be sure I have enough on hand when I plant in May. Amazing product and satisfied customer in Ohio

    I used this last year on my peppers and tomatoes and watermelon last year…. needless to say i had tomato runners two feet long. Pepper plants kept producing until the first frost, and the watermelons were absolutely huge and delicious.

    My major complaint is not being able to get more. I have been on the wait list for at least 4 months. I need to find something as good but that is readily available when I need it.

    • It is in stock and has been in and out of stock for months 🙂 Sorry that it sells so quickly!

    I love your trifecta blend! I have used it in containers and my in-ground garden. This year I added it to my seed starting mix & have noticed my tomato seedlings are much sturdier this year than in previous seasons (same varieties). Thanks for a great product!!!

    My raised bed AND container veggies have been rockin’ and rollin’ thanks to this fertilizer: big difference from last year! Between your fertilizer and watching as many of your YouTube vids as I can TO LEARN WHAT AND HOW TO DO THINGS, I am now growing my own food, whereas the last two years I was really struggling….so THANK YOU LUKE!!!

    We had a freak hail storm mid June. It looked like all the plants were about to die. Leaves were shredded on a lot of the plants, all the leaves fell off the basil plants, and most of the branches were broken off the tomatoes. After a week or so, I lost a lot of my garden. I quickly ordered Tri+ as a last resort. Not only did the ones still standing survive, but they went absolutely crazy! The determinant tomatoes were supposed to get 3′ tall max, but mine are well over 4′ now and have a ton of fruits. The basil came back in full force to the point where I have to give a lot of it away. Since a lot of my garden died, I started some seeds inside and transplanted outdoors. I used Tri+ in the holes before adding the plants. All of the transplants survived without any shock. I’d like to note that I didn’t harden the transplants off before planting either.
    I will definitely be buying more next year!

    this is the first year i tried trifecta, other years i would need to fertilize every couple of weeks and would still get yellowing at the base leafs, i would also get disease in my tomatoes in july and fight it. this year at planting, I used trifecta along with some worm castings (from MI Garnder) and 10-20 rabbit poop pellets(from a friend). It poured here may and june , like flash flood type rains. I sat and watched for some signs of nutrient deficiency before i fertilized again. I sprayed with MI gardner’s cold pressed neem oil during the heavy rains but did not see blight (first time in years! I continued to watch for nutrient defficiency. I was impressed how balanced this fertilizer must be because i have had the perfect amount of leaves to tomatoes. i had them hanging like red ornaments all over from mid july till now. I have not fertilized my garden once… just some in seed starts and again at transplanting…. I have given my containers the MI Gardner’s 911 fertilizer. WOW! what a year. What healthy plants and productive plants!!! i have to plant my tomatoes in the same area every year and thought I doomed because of the previous years spores being in my garden beds. Im impressed with trifecta. I guess its true that healthy plants from the get go fight disease all year. Its now september and i still have loads of tomatoes i can’t even eat. When one is half eaten on the ground, i’m thinking….go ahead you poor hungry chipmunk’s help yourself i have plenty! Even though i don’t recommend not fertilizing your garden…this experiment has taught me if the soil and tiefecta for the season …my plants are doing amazing!!! im not ready for the cold weather because my tomatoes wont stop producing! Great job guys!!! the bags of biostart, green sand, bloodmeal, azomite, epsom salts, phosphorus, stinky fish fertilizer and kelp are over!!! thanks for saving me a bundle!

    wow great Stuff. experimented with only using trifecta at seed start and transplanting. My tomatoes decorate my plants like a christmas tree. the perfect amount of foliage to tomato ratio. other years I had large plants 10 foot tall, with few tomatoes. This year I noticed they were about 5-6 feet, but strong, healthy and put out flowers like you wouldn’t believe. all different variates. its september 6th, still no fertilizer added and they wont quit. I have also Not gotten blight. every year before this the tomatoes were gone by end of august because of blight. NOT this year! yeah!!! didn’t add compost or anything except coffee grounds, fireplace wood ash and leaves over the fall and Trifecta and worm castings(MI Gardner’s) from the start. I used 911 in my containers as heavy down pours in may and june wash a lot out. I used MI gardeners cold pressed neem oil once a week in between the rains and Wow! I no longer have to buys bags and bags of all these expensive fertilizers, fish and kelp emulsions. From now on… worm castings and trifecta!! and good fall prep. thanks for saving me so much money!

    I tried one bed with and one without this product. The production and overall health of the plants were night and day. Well worth spending the money.
