How to grow the coral cactus (Euphorbia lactea 'Cristata')? Water little but often, and pay attention to fertilizing and light

SummaryChoosing soil: use soil made by mixing pond mud, river mud and coal cinders for growing it. Watering and fertilizing: water little but often, do not water with water that is too alkaline or too acidic, and during the growth stage apply fertilizer once a month. Light and temperature: it can be given appropriate light, and the suitable growing temperature is between 15°C-20°C. Precautions: the coral cactus has spines, and its sap contains toxins, so it is not suitable for keeping indoors.

1. Choosing soil

For the coral cactus it is suitable to use soil made by mixing pond mud, river mud and coal cinders, with pond mud and river mud making up a relatively large proportion; soil mixed in this way will have good air permeability and drainage, which helps promote the growth and development of the coral cactus.

2. Watering and fertilizing

The coral cactus likes being watered with neutral water, so when watering, do not use water that is too acidic or too alkaline; water little but often, which helps promote its growth, so there must not be too much standing water in the coral cactus's pot, otherwise root rot easily occurs; during the vigorous growth stage of the coral cactus, water about once every 6-7 days, until the soil is moist.

In summer when the weather is dry, watering can be a little more frequent, and during this period it can be watered once a day, but not thoroughly; in winter, if the soil is not dry there is no need to water, and on rainy days when there is too much standing water, pay attention to drainage; the temperature of the water when watering should not differ too much from the indoor temperature; the coral cactus needs a small amount of base fertilizer when planted, and during the growth period it can be fertilized once a month; during the flowering period a small amount of flower fertilizer can be applied to promote flowering of the coral cactus.

3. Light and temperature

The coral cactus is a relatively light-loving plant, and it also likes growing in a warm environment, but it is not very cold-tolerant; during the growth of the coral cactus, ensure there is sufficient light; in spring and autumn it can be exposed to direct light, in summer pay attention to providing appropriate shade, and in winter when the weather is cold pay attention to keeping the coral cactus warm and ensure there is sufficient sunlight; the suitable growing temperature for the coral cactus is between 15°C-20°C.

4. Precautions

1. In winter, water little but often as appropriate; excessive watering will cause root rot in the coral cactus, and too much water will make the branches grow vigorously with fewer flowers.

2. Suitable temperature and light can promote the coral cactus to produce more flowers, and the flower colors will also be bright and glossy.

3. The coral cactus is not suitable for keeping indoors, because the coral cactus has spines and its sap contains toxins, which can harm people's health, and long-term contact can easily cause cancer.
