How to fertilize canna

Canna fertilization method

In addition to applying sufficient base fertilizer before planting, it is necessary to apply thin fertilizer 3-4 times during the growing season. After canna is transplanted, it is necessary to water it thoroughly. When it grows 5-6 leaves, it needs to be fertilized with liquid fertilizer every half a month. You can use decomposed thin bean cake water and add an appropriate amount of ferrous sulfate as liquid fertilizer, or you can use a compound fertilizer solution with a lighter concentration.

Canna fertilizer dosage

Whether before planting or during the growth process, canna must be fertilized enough to ensure adequate nutrient supply. The sufficient amount here does not mean applying too much fertilizer at once, but that the overall fertilizer supply should be sufficient. Because canna likes fertile soil, fertilization can follow the principle of small amounts and multiple times. Especially during the growing season, fertilizer should be applied every week. Liquid fertilizer or thin fertilizer can be applied. When the canna is sprouting flower stalks, liquid fertilizer can also be sprayed on the leaves to promote flowering. However, in summer, you should reduce the amount of fertilizer because it is too hot and excessive fertilizer may burn the rhizomes and cause their death. Also, don't fertilize when cannas are blooming.

Canna Fertilizer Selection

When fertilizing cannas, pay attention to supplementing nitrogen, phosphorus, potassium and trace elements, and apply less ferrous sulfate. You can use Yongkang flower fertilizer, which is more suitable for cannas.

This is the end of the sharing of the canna fertilization method. I hope it will be helpful to flower lovers who like and grow cannas.
