What to Do When Clivia Leaves Develop Spots? Common Disease Prevention and Control Methods
Nowadays many people like to grow some plants at home, which not only helps pass the time but also makes the home feel more cozy. More and more people like to keep clivia at home. You can often hear people ask: what should I do if the leaves of my clivia develop spots? Are there any preventive methods? Today I will mainly teach you some simple methods for preventing and controlling common clivia diseases.
What to Do When Clivia Leaves Develop Spots
1. First, prevent the plant from developing root rot so that the leaves can get sufficient nutrients. Second, avoid external injuries and prevent wounds from spreading. The amount of fertilizer applied must be strictly controlled, and never over-fertilize. In summer, do not water large mature plants at the pseudobulb. In summer, pay attention to ventilation, lower the temperature, strengthen management, and regularly spray sterilizing agents such as carbendazim, chlorothalonil, thiophanate-methyl, and agricultural streptomycin for prevention and control. This can reduce and even eliminate the occurrence of leaf spot disease and leaf yellowing disease.
2. To prevent and control leaf spot disease, changing the soil can solve the problem. When changing the soil, wash the fleshy roots clean with water, let them dry, and then repot them. If some leaves have already rotted beyond recognition, just cut them off.
3. Junte is an organic sulfur-arsenic compound fungicide that can prevent and control a variety of fungal diseases, such as white rot, brown spot, and stem spot. Use a concentration of 500-1000 times dilution, spray once every half month, and spray 3-4 times in a row for effectiveness. Tuzite is toxic, so pay attention to safety when using it.
Common Prevention and Control Methods for Clivia Diseases
1. Leaf spot disease is a disease that can make plant leaves turn black. This disease generally only affects the leaf parts of the plant. At the beginning, leaf spot disease appears on the leaves as faded green yellow spots. Leaf spot disease generally occurs from July to October.
2. Prevention and control method: once diseased leaves are found, eliminate them promptly. If discovered right away, wipe them off with a rag or other tool, do not let them remain on the leaves, and reduce the residual pathogen as much as possible so that there are fewer pathogens. Normally enhance the air circulation in the room so that the air can flow, reducing opportunities for bacteria to arise and multiply.
3. Anthracnose is one of the more common diseases in the process of growing clivia. At the beginning of the disease, some light brown small spots appear on the leaves. Prevention and control method: when cultivating clivia, do not apply excessive nitrogen fertilizer. Apply an appropriate amount of phosphorus and potassium fertilizer. These trace element fertilizers can improve the plant's disease resistance and immunity, making its ability to resist pathogens stronger.
How to Handle Clivia with a Rotten Heart
1. When the rotten heart of clivia is not very serious, there is still a chance to save it. At the beginning, the tender leaves at the very center of the plant start to rot. At this time, remove the rotten leaves promptly, wipe the oozing sap clean with a paper towel, keep the surface dry, and place the plant in a ventilated and bright place, avoiding strong light.
2. If the rotten heart of clivia is severe and it is determined that it cannot be saved, you can directly remove all the leaves on one side of the plant, and the sooner the better. This can ensure that water does not accumulate in the center of the plant, avoiding further damage. Cutting off the leaves can also reduce nutrient consumption and help new shoots sprout. Use your hands to break off the leaves on one side of the plant one by one until the rotten pseudobulb is exposed, then use a sterilized bamboo strip to remove the rotten parts until the bulb returns to white.
How to Grow Clivia So It Grows Fast
1. Soil: Clivia is suitable for acidic soil rich in organic matter, and it should have good air permeability and sufficient moisture but not be overly saturated. It can be mixed with 65% humus soil, 20% clean sand, and 15% fine furnace ash. During the growth process, it needs to be repotted constantly.
2. Fertilizing: Clivia should be given a solid fertilizer once in winter, with less nitrogen fertilizer and more phosphorus and potassium fertilizer. A nitrogen, phosphorus, and potassium compound fertilizer can also be applied to promote the sprouting of more new plants and leaves, but fertilizing must be done in the right amount, and never apply concentrated fertilizer or raw fertilizer that has not been fermented and decomposed.
3. Watering: About every 20 days, clivia can be watered together with a fermented soybean cake water, dilute fishy water, and water from soaked water chestnuts, etc. When the room temperature is low, watering should be controlled to prevent the potting soil from becoming too wet. Too wet potting soil will cause root rot and death of the plant, but the potting soil should not be allowed to become too dry either.
Actually, growing plants looks like a very simple thing, but there is a lot of knowledge in it. Growing plants well is not only related to the growing environment, but also has a lot to do with the grower's skill. I hope the simple methods I taught you today can be put to use in your daily life.
