Frequently Asked Questions (FAQs)
1. Is water soluble fertilizer better?
Water soluble fertilizers have their advantages. They are less likely to harm plants but need to be reapplied more frequently. While they may be slightly more expensive than dry, slow-release products, the ability to deliver specific nutrients exactly where and when needed can make them worth it for some gardeners.
2. Can you dissolve fertilizer in water for plants?
Yes, you can dissolve fertilizer in water for plants. Use 1 cup of fertilizer for each gallon of water. Soak the fertilizer in the water for 24 hours, stirring periodically. Strain out the solids and use the liquid as a fertilizer at the recommended rates for different types of plants.
3. What are the disadvantages of water soluble fertilizers?
Water soluble fertilizers have some drawbacks. Heavy rain or excessive irrigation can cause nitrogen and phosphorous run-offs, polluting waterways and leading to algae blooms and fish kills. These fertilizers release nutrients faster than plants can absorb, making them less efficient.
4. How do you make your own water soluble fertilizer?
To make your own water soluble fertilizer, you can mix processed poultry manure or dry organic fertilizer with lukewarm water in a jar. Shake it vigorously and let it sit for two days at room temperature. Then, pour off the liquid and dilute it with water to the desired strength.
