Works great BTW! **Q: Will this work well for a ficus (rubber tree)?** A: I use this on a number of my ficus trees, including elastica, Benjamina, and lyrata. I alternate between regular watrings and fertilized waterings, and then stop during the winter. **Q: can this be used in hydro dwc?** A: No this should not be used for hydroponics. It is formulated with urea, which is not the best nitrogen source for hydro. Urea is not readily available to the roots in hydro and also it may give you pH problems because it will acidify your medium. ## Frequently Bought Together - Jack's Classic 20-20-20 All Purpose Water-Soluble Fertilizer with Micronutrients to Provide General Growth on All Plants, 1.5lbs - Jack's Classic 12-15-30 Veggie Feed Water-Soluble Fertilizer with Micronutrients for Plant Growth and Abundant Fruit Set in Blooming Vegetable Plants, 1.5lbs, 2 Pack - Jack's Classic Blossom Booster 1.5 lbs, 10-30-20 --- ## 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.sk/products/12049354-20-20-20-all-purpose-water-soluble-fertilizer-1-5lb](https://www.desertcart.sk/products/12049354-20-20-20-all-purpose-water-soluble-fertilizer-1-5lb) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-03*
