How to fertilize nasturtium

What fertilizer to use

Calcium phosphate is the fertilizer of choice for nasturtiums. It is best to use less nitrogen fertilizer, a growth-promoting fertilizer, because it can easily cause branches and leaves to grow too long.

Thin, decomposed cake fertilizer water is also a very good fertilizer.

How to fertilize during the growing season

During the growth process, 20% decomposed bean cake water is usually applied once a month.

How to fertilize during flowering period

Stop applying nitrogen fertilizer during the flowering period and instead apply 0.5% superphosphate or decomposed chicken and duck manure water once every half a month.

How to fertilize after the flowers fade

After the flowers fade, apply 30% decomposed bean cake water as top dressing to replenish the nutrients consumed by flowering.

Is it necessary to apply fertilizer in summer and autumn?

Stop fertilizing when the weather is hot in summer, otherwise the plants may be burned to death.

Apply compound winter fertilizer again in late autumn to enhance the plant's resistance to cold.
