How should you fertilize geraniums during the flowering period, and can you apply slow-release fertilizer?

Original title: How should geraniums be fertilized when they are flowering, and can slow-release fertilizer be applied?

Summary: If I want geraniums to grow better and bloom more abundantly, then of course they need fertilizer. How do we fertilize geraniums so that they can grow better? Today let's talk about how geraniums should be fertilized when they are flowering, and whether slow-release fertilizer can be applied.

How to fertilize

For fertilizing geraniums, only by applying good fertilizer can they grow better. First, let's understand how to fertilize geraniums when they are flowering. Actually, when we care for them it is all very simple, and geraniums have fairly vigorous growth ability, so when fertilizing we only need to pay a certain amount of attention.

Compound fertilizer

When geraniums are flowering, we had best choose some compound fertilizer. Actually, compound fertilizer has no bad effect on geraniums, and geraniums are different during their flowering period. Spring and autumn are their peak growing seasons. If we want to keep geraniums growing very well and vigorously, then we need to give them sufficient nutrients. What fertilizer should we apply for geraniums?

What fertilizer to apply

Those of us who have cared for geraniums all know that they do not much like nitrogen fertilizer, so we should choose some compound fertilizer containing phosphorus. Also, when fertilizing we must not apply too much fertilizer, and we must not apply fertilizer that is too concentrated or too raw, as all of these can easily burn their root system. When we fertilize geraniums, we can fertilize according to the size of the flowerpot.

Flowerpot size

If the flowerpot we choose is relatively small, then we need to fertilize it once before it blooms. Fertilizing before it blooms is the fertilizer it needs when flowering. After it has finished flowering, we should appropriately supplement some fertilizer for it, because it consumed a lot of nutrients while flowering. We can choose some liquid fertilizer for it, so that it can be watered directly. If what you choose is granular fertilizer, then it needs to be buried beside its potting soil, and we had best keep it some distance from the root system.

Slow-release fertilizer

However, the absorption of fertilizer by geraniums has a certain time limit, and you do not know whether its fertilizer has been used up. Actually, the fertilizer in general slow-release fertilizer can last 6 to 9, and at this time we only need to pay attention to the growth trend of the geranium. When its leaves and its plant show signs of malnutrition, that is, the phenomenon of some yellowing and a reduction in flower spikes, this shows that the fertilizer has already been used up, and we can promptly supplement some fertilizer for it, and it will slowly recover on its own.

What fertilizer to choose

Moreover, when we fertilize geraniums, we also need to pay attention to what fertilizer is being used. Geraniums quite like fertilizer, but exactly what fertilizer they like, none of us knows. When we buy fertilizer, the packaging generally shows the ratio of nitrogen, phosphorus and potassium, but the factors needed at different stages are also different, so we should consider it before choosing what fertilizer to buy.

Conclusion: Have you fertilized the geraniums you grow at home? After all, autumn is now their peak growing season, and when they are flowering we should fertilize them in this way, and we can also apply some slow-release fertilizer for them.
