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! Review: Fantastic! Revived my petunias! - Wow! This really revived my ailing petunias. They were starting to look like they were giving up, but two weeks later, they are back to healthy! It's easy to use and dissolved fairly well in water. I gave each of my very large outdoor urns a gallon of water with the recommended amount of feed, and it worked beautifully. I'm happy about the amount of product, too. This is going to last me a while! ## Features - 20-6-22 Analysis: Great for producing lush green iron dependent annuals in any growing condition. - Many Ways to Feed: Petunia FeED can be used as a foliar or root feeding product. Great for spraying directly onto leaves, roots, or when used in a continuous feed system. - Water-Soluble Powder: Powdered concentrates go further than liquid fertilizers. Simply mix your measured powder with water and you are ready to feed with multiple gallons of liquid fertilizer! - Included Measuring Spoon: All Jack’s Classic fertilizers come with a convenient spoon to create the right amount of liquid fertilizer for your plants. - Micronutrients: Added micronutrients supply your plant with the nutrition it needs for optimal growth and health. Unlike other fertilizers, additional feeding is not required. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07G5SGVNS | | Application Method | foliar or root feeding | | Best Sellers Rank | #7,301 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #254 in Garden Fertilizers | | Brand | Jack's Classic | | Brand Name | Jack's Classic | | Coverage | Medium | | Customer Reviews | 4.8 out of 5 stars 2,712 Reviews | | Included Components | B07G5SGVNS | | Item Form | Powder | | Item Weight | 4 pounds | | Manufacturer | JR Peters | | Model Number | 52664 | | Number of Items | 1 | | Part Number | 52664 | | Specific Uses For Product | Bloom Production | | Target Species | petunia, calibrachoa, bacopa, verbena, vinca and salvia | | UPC | 671341526643 | | Unit Count | 64 Ounce | ## Product Details - **Brand:** Jack's Classic - **Item Form:** Powder - **Item Weight:** 4 Pounds - **Manufacturer:** JR Peters - **Specific Uses For Product:** Bloom Production ## Images ![Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer, 4lb - Image 1](https://m.media-amazon.com/images/I/71wSHUbz60L.jpg) ![Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer, 4lb - Image 2](https://m.media-amazon.com/images/I/812giZ6OiNL.jpg) ![Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer, 4lb - Image 3](https://m.media-amazon.com/images/I/81lZwTP3VEL.jpg) ![Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer, 4lb - Image 4](https://m.media-amazon.com/images/I/81cAeAeiLtL.jpg) ![Jack's Classic 20-6-22 Petunia Feed Water-Soluble Fertilizer, 4lb - Image 5](https://m.media-amazon.com/images/I/816lR5gmapL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing fertilizer for lush wave petunias *by K***L on November 28, 2025* I've used this petunia fertilizer for three years now on my potted wave petunias with great success.
