What fertilizer is best for cactus (what fertilizer makes cactus grow faster)

How to fertilize cactus

When fertilizing cacti, it is important to distinguish the seasons, and use the temperature to help determine whether the cactus has entered a dormant period.

The recommended temperature for fertilization is between 18 and 30 degrees Celsius. If the temperature is below 10 degrees Celsius, the plant is in dormancy and no fertilizer is needed. If the temperature is above 32 degrees Celsius, the plant is in dormancy and no fertilizer is needed.

When fertilizing cacti, be sure to apply thin fertilizers frequently, and prefer less rather than more.

The cactus does not have a strong ability to absorb nutrients. If too much fertilizer is used, it will cause the roots to burn. Therefore, it is better to dilute it more times and then slowly master the correct amount to achieve the maximum fertilizer effect when applying fertilizer.

What fertilizer is good for cactus

The growth of cactus is divided into vegetative growth and reproductive growth. Vegetative growth needs to enter adulthood for a period of time before it can be transformed into reproductive growth. The amount and type of fertilizer should be adjusted according to the different growth stages. Pay attention to the following 3 points when applying fertilizer:

1. Daily fertilization

It is recommended to use organic fertilizer for daily fertilization of cactus. By loosening the soil, bury the "fermented sheep dung balls" shallowly in the shallow surface soil once a month. When fertilizing, be careful not to let the granular fertilizer stick to the fleshy stems.

Daily fertilization is "nitrogen as the main and phosphorus and potassium as the auxiliary". The role of phosphorus and potassium at this time is to promote root growth, so they can be used as auxiliary fertilizers .

2. Fertilize during the growth period

The daily fertilization of cactus mainly supplies normal growth needs, but in spring and autumn, there will be a short period of vigorous growth. At this time, in addition to the daily use of organic fertilizer, you can also add "organic fertilizer water" once a month.

It is recommended to use "fermented rice water" diluted three times the amount of water and water the flower soil along the edge of the pot.

3. Fertilize during flowering period

The maturity period varies according to the species of cactus. About one month before the flowering period of the adult cactus, you can use organic fertilizer with "phosphorus and potassium as the main and nitrogen as the supplement".

The simplest way is to keep fertilizing every day, and then spray a 1200 times aqueous solution of "potassium dihydrogen phosphate". This can promote flowering and prolong the flowering period.
