Purple Shamrock Plant Light

Purple Shamrock plant is not afraid of sun exposure. It likes light very much. Photosynthesis can be better carried out under the environment of sufficient light, so as to accumulate more nutrients. The leaf color of purple Shamrock plant will look brighter and bloom better. During the maintenance period, we can put the plants in a well lit environment and give full sunshine.

Purple Shamrock Plant Temperature

The suitable temperature for the growth of purple Shamrock plant is 15 ~ 30 ° C. when the temperature exceeds 36 ° C in summer, the leaves are easy to curl and wither. Therefore, in hot summer, we should regularly spray water on the leaves of purple Shamrock plant. If the room temperature is lower than 5 ° C in winter, its leaves are vulnerable to freezing damage.

Purple Shamrock Plant Humidity

Purple Shamrock plant likes a warm and humid environment all year round and has a slight drought resistance. However, it should pay attention to watering regularly when raising in the flower pot. We can keep the soil slightly wet in spring and summer. However, we should consider the location of the purple Shamrock plant. If it is raised in a place with more light, the soil should be kept slightly wet. In a place with indoor shade, it can be supplemented with water after the soil is completely dry.

Purple Shamrock Plant Fertilizer

Purple Shamrock plant consumes a lot of nutrients during its growth. It should be fertilized and supplemented in time to grow vigorously only when the nutrients are sufficient. The fertilizer applied can be determined according to the growth stage. At the beginning of the basin, an appropriate amount of base fertilizer should be added to make the soil more fertile. Apply nitrogen, phosphorus and potassium compound fertilizer in peak growth season, and pay attention to controlling the fertilizer concentration. It is recommended to dilute it with clean water before watering it on the soil surface, so that the purple Shamrock plant can absorb it faster. If the concentration is high, it will bring fertilizer damage and burn the plant easily.

Purple Shamrock Plant Pruning

We should trim purple Shamrock plant in time during the management period, and remove the dense leaves in time when the growth is too strong, so as to improve the ventilation and air permeability, promote better light transmission and promote growth. At ordinary times, if we find that the purple Shamrock plant is yellowing, the dry leaves should be cut off in time, which can not only reduce nutrient consumption, but also avoid infection with diseases and pests. In addition, if the plant type is not beautiful, it can also be re cut. It has strong germination ability and can grow new leaves soon after proper management.

Purple Shamrock Plant Repotting

When the fifth true leaf grows from the bud of purple Shamrock plant, we can change the pot. It should be noted that the pot change time of purple Shamrock plant should not be too early or too late. If the pot change is too early, the buds and seedlings are fragile, it is difficult to slow down the seedling stage, and transplanting too late is easy to cause serious damage to the root system. When changing pots, purple Shamrock plant needs to retain the old soil on its roots, plant according to the density of two plants in each pot, give some astigmatism irradiation after planting, ensure that the soil is wet, and strengthen ventilation management, so as to promote the growth of purple Shamrock plant.

Purple Shamrock Plant Pest & Disease Control

  • Leaf spot
This kind of purple Shamrock plant disease usually occurs from early May to early September. When purple Shamrock plant is infected with leaf spot disease, the leaves will appear Lavender irregular spots. In the later stage, the spots will turn yellowish brown and gradually expand, and the leaves will become dry and shrink. 70% methyltobuzin with 1000 times liquid can be selected, which is suitable for use in the early stage of disease. Carbendazim with 500 times liquid can also be used to spray alternately. At the same time, we should strengthen field management, remove dead leaves and miscellaneous leaves in time, and apply fertilizer and water reasonably.
  • Root rot
This purpose Shamrock plant disease is easy to occur in high temperature and humid environment. In case of such diseases, the root will shrink, the plant will grow worse and worse, the leaves will wither and yellow, and the main root will slowly turn black brown and rot. In the early stage of the disease, 500 times of methyltobuzine can be used, and 1000 times of methyltobuzine or 700 times of tuxetine can be used in the later stage. At ordinary times, we should pay attention to cleaning the cultivation site, fertilizing reasonably and keeping the soil moist.
  • Botrytis Cinerea
This purpose Shamrock plant disease is prevalent in early spring or in low temperature and high humidity. The damaged leaves will begin to appear yellowish brown water stains, which will slowly dry the leaves, damage the bulbs, and even lead to the death of the whole plant in serious cases. In the early stage of the disease, carbendazim with 500-800 times liquid can be used for prevention and treatment. At ordinary times, it is necessary to ensure that the field management is in place, maintain good ventilation between plants, plant reasonably and closely, and water frequently after the disease.

Purple Shamrock Plant Propagation

Purple Shamrock Plant Propagation from Division

We can choose to divide in spring and autumn to avoid hot summer and cold winter, so that the bulb can have a suitable growth temperature and promote its growth. We should select the mother plant with vigorous growth, strong activity and no damage by diseases and pests, and the growth time is more than two years, because the small bulb isolated from this mother plant has strong growth ability, which can greatly improve the success rate of ramet. We can use a seedling pot of moderate size, or a common plastic pot in life. This kind of flowerpot is not only cheap, but also manually increase the number of drainage holes to ensure that the flowerpot has good air permeability and drainage.
After the purple Shamrock plant propagation from division, we can pour water once to make the tubers closely combine with the soil. In the later stage, we should control the application of water and make appropriate water supplement after the soil turns white and dry. After the split of purple Shamrock plant, we should not expose it to strong light immediately. We need to maintain it in a cool and ventilated place for a period of time, and then give some astigmatism irradiation appropriately. In addition, because the newly prepared soil has sufficient nutrient content, it is not necessary to apply fertilizer immediately after branching, so as to avoid fertilizer damage.

Purple Shamrock Plant Propagation from Seed

The seeds of purple Shamrock plant are too small. We can't grasp these seeds directly by hand when sowing. We need to fully mix the seeds with a small amount of soil and then sprinkle them evenly in the seedling soil. This can not only avoid the overlapping of seeds, but also avoid the disorderly growth of buds and seedlings. After the seeds of purple Shamrock plant are sown, we can gently press them with our hands, and then cover the flowerpot with a layer of plastic preservative film to keep warm and moisturize. We can see the germination of purple shamrock plant seeds in about 10 days.
It should be noted that before sowing in purple Shamrock plant, we'd better spray some water on the soil with a water spray bottle, and then sow after wetting it. In this way, we can not water the seeds temporarily after sowing, so as to avoid the small seeds being washed away by water.
After sowing in purple Shamrock plant, we should not immediately put it under strong light for curing to prevent the seeds from being scalded due to the rise of soil temperature. We can first put purple Shamrock plant in a cool and ventilated place for curing for a few days, and then give some astigmatism irradiation appropriately after the seeds germinate. During the management period, do not water a large amount of water frequently, let alone ponding in the soil, so as to avoid the rot of purple Shamrock plant seeds in the excessively wet soil environment for a long time. In addition, do a good job in temperature management, and try to control the temperature at about 18 ℃, so as to speed up the germination time of seeds.
