How to grow the crown of thorns and what to note when planting it

The crown of thorns looks like a rooster's comb in shape, but the milky sap it secretes is toxic, and if swallowed by mistake it will cause poisoning. Special attention must be paid to how to grow the crown of thorns. Let us take a look together.

1. How to grow the crown of thorns -- cuttings

For cuttings of the crown of thorns, in May you need to cut off relatively thick and sturdy branches, let them dry in the air, and wait until the cut ends are completely shriveled and dry. Under suitable temperatures, they will take root and grow stems after about fifty days. When planting the crown of thorns in summer, attention must be paid to shading and ventilation. You can appropriately turn the side of the crown of thorns facing the light, so that the shaded branches grow more evenly.

2. How to grow the crown of thorns -- light

Poor light will cause uneven growth of the crown of thorns and lead to a certain amount of leggy growth. During the growth stage, light must be ensured, but it also cannot be placed outdoors for a long time. In winter, the plant needs light to maintain photosynthesis, so choose a sunny place for the crown of thorns.

3. How to grow the crown of thorns -- watering

How to grow the crown of thorns

Soil

For the crown of thorns, it is best to use a medium made by mixing river mud, pond mud and coal cinder, with river mud and pond mud making up a relatively large proportion. This kind of soil is breathable and has good drainage, which is beneficial to the growth of the crown of thorns.

Watering and fertilizing

The crown of thorns likes neutral water, and when watering, the water quality must not be too strongly acidic or alkaline. Do not water too much; it is harmful and not beneficial, so there must be no standing water in the flower pot of the crown of thorns, otherwise it will cause root rot, stem rot, or even the whole plant rotting away. During the vigorous growth period, the crown of thorns can be watered once every 6 to 7 days, basically following the principle of watering when dry and keeping it moist. In summer, watering can be more frequent, once a day, but do not water thoroughly; in winter, basically do not water unless it is dry; during the rainy season, pay attention to drainage. Note that the temperature of the water must not differ too much from that indoors. When planting the crown of thorns, some base fertilizer needs to be applied, and during the growth period it can be fertilized once a month; during the flowering period, some flower fertilizer can be applied to promote flowering.

Light and temperature

The crown of thorns originates from the deserts of South America, relatively likes light, and also likes a warm growing environment, and is not cold-tolerant. During the growth period, ample light must be maintained; in spring and autumn it can be exposed to direct light, in summer attention must be paid to shading, and in winter the crown of thorns can be placed in a sunny spot indoors for care. The crown of thorns likes warmth and is not very cold-tolerant, and the growing temperature must be kept between 15°C and 20°C. In winter, attention must be paid to keeping it warm, and the crown of thorns should be placed indoors to overwinter.

Pruning

During the growth process of the crown of thorns, the branches do not branch easily and will grow very long, making the plant shape unattractive and reducing flowering, which affects its ornamental value, so it must be pruned frequently. Cut off the overly dense and overly long branches so that it can branch more and bloom more.

Improper care

If the crown of thorns is cared for improperly, for example with insufficient light, the flower color will become dull, and long-term excessive shade will cause it not to bloom. Water and fertilizer management need to be done well, and should not be excessive, otherwise the plant will grow leggy and may show a reversion phenomenon, affecting its ornamental value.

Repotting

The crown of thorns can be repotted once every 1-2 years, and when repotting, the soil must be removed and the roots trimmed. After potting, keep the potting soil moist, first place the crown of thorns indoors for about ten days, and then move it outdoors.
