3. It Can Be Used Around Flowering Plants
You’ll often see banana-peel mixtures recommended for roses, geraniums, petunias, and other flowering plants.
Potassium is involved in many aspects of plant growth, so the idea isn’t completely random.
But the popular statement that “potassium makes plants flower” oversimplifies plant nutrition.
Flowering depends on numerous factors, including:
Plant genetics
Sunlight
Temperature
Plant maturity
Water
Pruning
Nitrogen balance
Phosphorus
Potassium
Overall plant health
If a rose isn’t flowering because it’s sitting in deep shade, banana water won’t fix it.
