It sounds like the description for a hose!** A: Yes, this looks like the wrong info for this product. The product is great, but it is for Hydrangea flowers, this is not a garden tool. **Q: Will this turn pink hydrangeas blue?** A: I used it late winter early spring and every flower is now blue-purple. I just noticed in mid July pink flowers are coming again so I will add some more **Q: Is this good for bigleaf hydrangeas?** A: I guess I don’t Know the difference. But I would expect it to be good for hydrangeas in general🤷🏼‍♀️ Sorry I can’t be of more help to a fellow gardner **Q: Silly question, when it suggests 1 tablespoon per gallon of water or table per gallon of root ball?** A: It means to use 1 tablespoon per gallon of water to use watering around the root ball area. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by B***G on August 13, 2024* ### ⭐⭐⭐⭐⭐ Review *by A***A on May 29, 2024* ### ⭐⭐⭐⭐ Review *by J***N on April 26, 2024* ## Frequently Bought Together - Jack's Classic 7-3-3 Hydrangea Blue Water-Soluble Fertilizer with Micronutrients to Enhance Blue Flowers, 1.5lbs - GARDENWISE Slow Release Hydrangea Fertilizer with Iron & Sulfur – Indoor & Outdoor Soil Acidifier for Miracle Growth (12 oz) - TPS NUTRIENTS Hydrangea Fertilizer for Acid Loving Plants, Liquid Plant Food 8 oz (250mL) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/26946821-jacks-classic-7-3-3-hydrangea-blue-water-soluble-fertilizer](https://www.desertcart.pl/products/26946821-jacks-classic-7-3-3-hydrangea-blue-water-soluble-fertilizer) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-29*
