Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer with Micronutrients to Provide Lush Green Annuals, 1.5lbs

I've used this petunia fertilizer for three years now on my potted wave petunias with great success. Petunias are heavy feeders, so they can start to look yellow or not grow as many flowers if they aren't fertilized properly. I used this once a week and it kept them growing beautifully. I ended up with a ton of flowers on every plant. It's really easy to use, and it comes with a little measuring scooper to help you get the exact amount for your watering can. A lot of mix comes in one container, so it's a great value for the money if you want lush flowers. Your neighbors will definitely be impressed!

Love this stuff! Keeps my petunias happy and healthy all season long. It really does make a difference for me in the appearance of my pots. They grow faster and just look better overall.

This was suggested to me last spring as the best fertilizer for petunias from local nursery. And they were right! I have extensive flower gardens and my potted petunias started to get bad mid September. Now for the last two years my 8 large pots look fantastic right up to frost. And it's also great for lantana's! I plant those in the ground and compared to other fertilizers it works far better.

Easy to use and VERY effective! Add one scoop per gallon of water and you’re good to go. My daughter gave me a petunia for Mother’s Day, I promptly ordered this product after doing some research and it did not disappoint! My blooms are big, beautiful, and plentiful. I mix up a gallon each week, and give half gallon 2x weekly. These pics are of when I received my plant in May and two months later, in July. Highly recommend. This product has definitely done its job. You get a lot of product for the price.

Growing and maintaining plants in Wyoming is challenging given extreme temperature changes and a short growing season. Yearly, I buy two petunia hanging baskets for my front porch but they typically only last about 2 months due to them becoming leggy and eventually drying up and losing blooms. This year I decided to do some research to see what I was doing wrong and how I could help to extend their lives. This product came highly recommended on several gardening sites and nursery you tube channels so I decided to give it a shot! Before using the mix, I cut about 6-8 inches off each of the petunia stems. This cut most of my blooms but they were looking leggy and bad anyway. I also learned that when deadheading petunias (which you should do!), to pinch or cut the entire bloom, not just pulling the flower out of it's holding place. Once the whole flower is removed (including it's green base), the plant will begin shooting up new blooms. I used one scoop of Petunia Feed in one gallon of water (just kept an old gallon milk container under my sink for easy measuring and filling) and split the gallon of water between my two hanging pots. I used the mix once a week and maintained my normal watering schedule. It took about 2 weeks for my petunia plants to grow and produce new blooms. When they did, I was so excited because they looked as good as when I bought them 2 months before! Fertilizing and deadheading/cutting tops definitely did the trick. I actually got so confident (and lazy) that I stopped using the fertilizer for a few weeks. Once again, my plants became leggy and weren't filling out in the middle of the pot. This was proof that the fertilizer was the key to keeping them healthy and full. I cut and returned to the weekly fertilization schedule and they're filling out and looking great again - long after plants in the past have lost their lives. I also used the fertilizer in my large patio pots and it really helped my flowers to rebloom and maintain their fullness and greenery. It also helped other flowers in those pots to have several rounds of blooms when previous summers I only got 1-2. This Petunia Feed is well worth it's price and the container provides enough feed for several pots all summer long. I have used it on 2 hanging plants, 2 small pots, and 5 huge patio pots for about 1.5 months and there's still about the container left. I will continue to buy for seasons to come! 1st photo: when I cut them down and began Petunia Feed 2nd photo: 2 weeks after feed 3rd photo: potted plants 1 week after feed

So, I’ve taken up a new hobby—growing petunias. Don’t ask why, it just happened. And now, apparently, I’m feeding a new family member. Enter this questionable petunia food. Honestly, I’m not sure if it’s actually helping, but hey, it’s cheaper than therapy, right? According to my husband, I need to keep feeding "another family member" (petunia, that is), so here I am, watering my plants and sprinkling this food like it’s some kind of magic. Will it help my petunia thrive? Who knows. Will it make me feel like I’m accomplishing something in life? Absolutely. And the neighbors? They love my garden—full of flowers and vibrant life, while I’m just here pretending I know what I’m doing. So, there you go. Petunia’s fed, I’m entertained, and everyone’s happy... except maybe the local squirrels, but that’s a whole other story.

Bought these petunias April 2025. WOW, took this pic on 01/05/2026. Gotta love south Texas winter. 🤭 I’ve always had great results with Jack’s fertilizer.

First time I used this. I buy petunias every year in April to hang in the backyard. I fertilize every time I water. So pretty. Getting ready to order another container for next summer. Have had to trim them 2 times so far. Really pleased with product.

Parfait pour corriger en partie une eau trop calcaire. J’utilise Ph Down pour ajuster le reste. Des résultats spectaculaires avec mes gardenias
