Culture method of Purple Pearl

Purple pearl, also known as Nuremberg pearl, clove, etc., is a succulent plant of the genus Euphorbiaceae. It is mainly green for a long time, but the purple is not obvious. after entering autumn, the temperature difference between day and night is enlarged, and the leaves show purple, which is the best ornamental in autumn and winter. if placed in the sun, it will grow into rose petals, grow stems from leaves in late summer and early autumn, and bloom purplish orange flowers. Next, let's take a look at the culture methods of purple pearls.

Growth habits of Purple Pearl

Purple pearl likes light, warm, dry and ventilated environment, drought-resistant, cold-resistant, shade-resistant, indoor air-suffocating environment, extremely adaptable, not resistant to hot sun exposure, no obvious dormancy period. Maintain in a ventilated environment, otherwise it is easy to get sick. The suitable temperature for its growth is 1525 degrees, and not less than 5 degrees in winter. During the growing period, watering is dry and thoroughly, and water can be sprinkled around the plant when the air is dry. Shade is needed in summer, watering is reduced, and it is kept in the sunny place indoors in winter.

Propagation methods of Purple Pearl

1. Leaf insertion: lay the complete mature leaves on the moist sand with the leaves facing up and back down, without covering the soil and placing them in a shady place. in about 10 days, leaflets and new roots can grow from the base of the leaves, and the root system can be buried in the soil. after that, let it bask in the sun and water properly, and gradually it will grow into a strong new plant.

2. Branch cuttings: tillers or top branches are available for branch cuttings, and the cuttings cut are not limited in length, but the lower leaves should be removed after the cut is dried, and then inserted into the sand bed to avoid excessive water evaporation. It generally takes root about 20 days after insertion, and can be watered after rooting. It is a normal phenomenon that the bottom leaves are dry and atrophied before rooting. The root system grows well and will recover naturally after sufficient water absorption.

Culture method of Purple Pearl

1. Illumination: the more sufficient the light of purple pearl is, the greater the temperature difference between day and night is, the brighter the leaf color is. When the temperature permits, it is best to put outdoor maintenance to ensure adequate light, spring, autumn and winter maintenance, to ensure that the light is more than 4 hours a day, when the light is insufficient or the soil moisture is too much, the whole plant is light green or dark green, and the leaf sparse spacing elongation, accelerate upward growth, seriously affect ornamental, and may even die because of the hindrance of plant photosynthesis.

2, moisture: purple pearl plant has high water content, purple pearl is easy to rot in excessive humid environment, do not water too much. In order to avoid water deposition in the root, it is best to choose a basin with a drainage hole at the bottom, a red pottery basin with good air permeability can be selected for novice planting, and the glass container can be used with caution because of heat absorption and poor air permeability.

3. Soil: purple pearl should be cultivated in sandy soil with good drainage and air permeability, so as to remove excess water and plant root growth. It can be prepared with rotten leaf soil, sandy soil and garden soil. If the basin is changed every 1 ~ 2 years in spring, the necrotic old root can be cut off.

4. Temperature: purple pearl stops growing or slightly frostbitten when it is below 5 degrees Celsius, and the water frozen cells in leaves below 0 degrees Celsius are necrotic. When the temperature is too high (more than 35 degrees Celsius) or too low (less than five degrees Celsius) in winter and summer, the plant growth should be temporarily reduced or stopped, and the watering frequency should be restored when the temperature is suitable. Pay attention to ventilation during high temperatures in summer to prevent prolonged exposure to the sun to avoid sunburn.

5. Pruning: purple pearls need to remove dry old leaves in time at ordinary times, so as not to accumulate and lead to the growth of bacteria. When the plant grows excessively or grows too high, it can be molded by pruning the top branches and leaves and controlling the plant height to maintain the beauty of the plant type. The top part of the cut can be inserted into the sandy soil after drying the wound to take root and become a new plant. The stems and leaves at the bottom can sprout more lateral buds.

6. Fertilizer: purple pearl should not apply too much fertilizer, especially nitrogen fertilizer, otherwise it will cause overgrowth of plants and non-red leaves, and apply thin fertilizer dominated by phosphorus and potassium once a month. During the summer dormancy period, the growth is slow or even non-growing, and the nutrients required are relatively reduced, with little or no fertilization as far as possible.

7. Insect pests: the insect pests of purple pearl are mainly shell insects, and the initial pests are often found in the roots or the center of the plant. after the pests are found, they need to be isolated from other plants immediately, cut off the roots that breed shell insects, and can be sprayed on the affected area or killed by root irrigation (fungicides such as chlorothalonil and carbendazim do not have insecticidal effect). It may take several cycles to kill the shell insects completely, and a small amount of carbofuran or paracetamol can be mixed into the soil.

8. Disease: the common disease of purple pearl is mainly black rot, which needs to be isolated from other plants quickly after discovery. at the initial stage, the rotten part can be cut off thoroughly, and a little fungicide can be smeared on the notch. after the incision is dried, it can be inserted into the loose sand to take root again. If the black rot has spread to the growing point of the plant, it can be regarded as death and discarded as soon as possible to prevent infection. Other diseases can be treated by spraying diluted chlorothalonil, carbendazim and other fungicides, prevention can be mixed with a little chlorothalonil, carbendazim and other fungicides.
