- To delight with the abundance of flowers throughout the season, geraniums need intensive fertilization, especially in pots.
- Natural fertilizer, rich in potassium and phosphorus, is the key to spectacular flowering in June.
- Discover how to easily prepare this homemade elixir to make your geraniums bloom like never before!
Grind and water your geraniums in June and they will bloom like crazy
are one of the most popular flowers on Polish balconies. They owe their fame to their colorful flowers, but also to the fact that they are really easy to care for. However, if we want them to delight us with their appearance throughout the season, they need an appropriate dose of nutrients, as they are plants with high nutritional requirements. Intensive flowering and lush leaf growth absorb huge amounts of nutrients from the soil. In pots, where space for roots is limited, these resources are quickly depleted. Therefore, fertilizing geraniums is not only a matter of aesthetics, but above all, the health and vitality of the plants. So what can you do to make them bloom beautifully and thickly? It works great with banana peels.
Natural fertilizer for geraniums for flowering. How to prepare it from banana peels?
Banana peels contain large amounts of potassium, but also phosphorus, magnesium and calcium. Potassium is a key nutrient for geraniums because it stimulates the formation of flower buds and intensifies the color of flowers, as well as increases the plant’s resistance to diseases and pests. Therefore, if your geraniums bloom poorly, use this natural fertilizer based on banana peels and use it in May and June. How to prepare it?
- Collect some banana peels.
- Cut the peels into smaller pieces.
- Place the peels in a jar or other container and pour warm water over them.
- Set aside for 24-48 hours.
- Strain the infusion and dilute it with water in a 1:1 ratio.
- Water geraniums with the infusion once every 2-3 weeks.

Nutrients necessary for lush flowering of geraniums
For geraniums to delight with a storm of flowers throughout the season, they need a balanced diet. Three basic ingredients are key: nitrogen (N), phosphorus (P) and potassium (K). Nitrogen is responsible for the healthy growth of leaves and shoots, but its excess may have the opposite effect – the plant will be lush, but will bloom poorly. The true allies of flowers are phosphorus, which strengthens the root system and stimulates bud formation, and potassium, which is responsible for the intensity of color, size and number of flowers.
It is worth choosing fertilizers in which the dose of nitrogen is moderate and the content of potassium and phosphorus is increased. Such a composition, often enriched with microelements such as iron, magnesium or boron, will provide geraniums with everything they need for spectacular flowering from May until the first autumn frosts. The plants will not only bloom beautifully, but will also become more resistant to diseases and drying.
When and how often to fertilize geraniums? Schedule and directions
Regularity is the key to success in geranium care. We start fertilizing about 2 weeks after planting the plants in the final boxes, when their roots have already settled in well. Liquid fertilizers are most often used and are added to water during watering. It is worth repeating this treatment systematically every 1-2 weeks, preferably on a selected, fixed day of the week, so as not to forget about it. Remember to feed the plants in the morning or evening, avoiding fertilizing in full sun when the soil is very hot.
The fertilization cycle should be adapted to the plant’s future plans. If you plan to store geraniums over the winter, stop feeding them in mid-August. This will allow the shoots to properly prepare for the rest period. However, if you treat them as annual plants, you can continue fertilizing them even until September to enjoy their flowers as long as possible.
Correct dosage of fertilizers and the risk of over-fertilization
When fertilizing geraniums, the rule “the more, the better” definitely does not apply. Always follow the manufacturer’s recommendations on the product packaging. Measuring the correct dose is facilitated by special measuring cups, which are often the caps of fertilizer bottles. It is worth feeding young, freshly planted seedlings with half the recommended dose at the beginning, so as not to damage their delicate roots.
Over-fertilization, especially with excess nitrogen, may do more harm than good. Instead of a storm of flowers, we will see lush but brittle leaves and shoots, and flowering will be negligible. Moreover, too high a fertilizer concentration may lead to salinization of the soil, which makes it difficult for the plant to absorb water and nutrients, and in extreme cases it may even “burn” the roots. That is why it is so important to exercise moderation and carefully monitor the condition of plants.
