    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.

    Its So Goooooood!
    I live in a high desert climate and growing here is hard on any gardener.
    Every night since I planted it has been in the 30s every night.
    Even in July and August it will be 40 average at night and 90 to 100 in the day.
    The farmers almanac says I don’t have a last frost date!
    A good fertilizer is a must, as I only get half of every day to grow during the growing season (July to August) and by September It may be snowing again.
    I have tomatoes and peppers growing under these conditions with Trifecta + and Revive RX.
    The tomato stalks are healthy and I expect to get a good harvest this year.

    Thanks Luke

    Absolutely amazing, was fertilizing with miracle grow before and had ok results. Put trifecta down a week ago as a top dressing, did more then recommended but I have brand new raised beds that have low quality dirt. My plants literally exploded after a week of trifecta.

    I’m a first-time gardener and felt overwhelmed with so many fertilizers to choose from at the store. I was researching and looking for an organic fertilizer that is easy to use and works. I heard about Migardener fertilizer from another gardening youtuber calikim29. She swears by Trifecta and always uses it in her garden. I decided to try it and bought my first 15lb bag a recently and applied it to my dying with no flowers pepper plants. My pepper plants have not looked this good, they have produced so well, beautiful tasty peppers, and continue to produce her in Southern CA zone 10a. I am absolutely very very happy with this fertilizer. I will never buy a different one again, I just purchased another 15 lbs for my new fall plantings. I highly recommend this fertilizer, it’s easy to use, and gives the best results. Thank you calikim29 for the recommendation and thanks to Luke for his informative videos and for this unique fertilizer that meets all of my needs. Highly Recommend!!!

    As a child I helped in the garden. It had been many years of not gardening when bought a house and decided to start my own garden. My first year was difficult, getting to know the areas weather patterns and soil. About midway through my first year I discovered MIGardener. I began trying some of his suggestions. By the end of the season I tried this fertilizer. Phenomenal. Some of my plants weathered the winter and were fruiting again before transplants were even in the store! Never had that happened before. So I used this fertilizer solely my second year and again amazing results. This year we had freaky weather. Cold. Wet. Hot. Cold. Very Hot. Wet. Cold. Very hot for 6 weeks! (And I have the electric bill to prove it!) My garden is rich and plentiful. I planted Stupice Tomato seeds from MIGardener; Luke is right everyone should experience this tomato. I stopped counting at 35 tomatoes on ONE plant! Late spring I planted several peas and one pole bean (Luke’s seed). These cold weather vegetables did well despite the weather. However the pole beans should have died a long time ago because the weather was the worst. I have used this fertilizer and am still getting string beans well into Sept! If you’re on the fence about spending money on this product I suggest you try the 2lb bag. You’ll soon be buying the 15lb bag like I did. Amazing Phenomenal Product! Thanks Luke for making an old lady, an a cancer patient, able to eat her own clean organic food. You are inspiring, innovative, and an angel to share your knowledge and products with all of us. Please keep doing what you’re doing, and know you are immensely appreciated!!!

    I used this on my indeterminate tomato plants last year and they grew over 8 feet tall. I don’t want to use any other fertilizer. I just wish it was in stock more often. I guess that just proves how good it really is.

    Strawberries the size of crab apples seems to be the norm. I put this stuff on all of my strawberry beds last fall but one. Everyone can see the amazing differences . I hope to never be without this stuff. I bought two large packages to insure having it on hand and to share with my friends,

    Used Trifecta+ on all my plants this year. They are healthy and doing extremely well. I’ve noticed the biggest difference in my squash/zuch plants, they’ve never looked healthier!
