Best DIY Fertilizers for Geraniums
Natural fertilizers can provide supplemental nutrients while reducing reliance on synthetic products. When used properly, they may contribute to healthy growth and flowering.
1. Banana Peel Tea
Banana peels contain potassium and small amounts of phosphorus, nutrients that are important for flowering plants.
To make banana peel tea, chop leftover banana peels and soak them in water for two to four days. Use the infused water to irrigate your geraniums every few weeks.
As with any fertilizer, moderation is important. Observe how your plants respond and adjust accordingly.
2. Crushed Eggshells
Eggshells are a natural source of calcium, which supports cell development and overall plant health.
Allow eggshells to dry completely, then crush them into a fine powder. Mix a small amount into the soil around your geraniums once per month.
Calcium can contribute to stronger stems and improved root development when incorporated as part of a balanced gardening program.
3. Used Coffee Grounds
Used coffee grounds contain small amounts of nitrogen and organic matter that can enrich soil structure.
Apply them sparingly around the base of your geraniums. Excessive use may contribute too much nitrogen, potentially reducing flower production.
When used occasionally and in moderation, coffee grounds can be a useful soil amendment.
4. Compost Tea
Compost tea provides a gentle nutrient boost and can help improve soil biology.
Steep finished compost in water for one to two days, strain the liquid, and use it to water your plants.
This can serve as a temporary alternative to regular fertilizer applications while supplying a broad range of nutrients and beneficial microorganisms.
Although these homemade options are generally milder than many commercial fertilizers, they should still be used thoughtfully and not applied excessively.
Knowing whether your fertilization program is working can help you make adjustments before problems develop.
