How to plant red flower oxalis
Answering for netizens on how to plant red flower oxalis and sharing the experience of green plant maintenance in terms of cultivation techniques and care, it will definitely bring you some help. Let's learn about it together!
I. Soil Selection
Choose a loose, fertile sandy loam with good drainage. After selecting the soil, apply decomposed organic manure at about 2000 kilograms per mu uniformly, then turn the soil to a depth of 30-35 centimeters to evenly distribute the organic fertilizer in the soil. Level the ground and prepare the ridges for use.
II. Planting Methods
Since seed propagation results in slow seedling growth, division propagation is often used. Red flower oxalis has bulbous roots, and when the plant grows to a certain extent, many small bulbs appear around the mother plant's bulb. At this point, dig up the entire plant and separate the small plants around the mother plant for transplanting. Generally, 6-8 small plants are planted in one shallow pit, with a distance of 15-20 centimeters between pits. After planting, cover the soil 1-2 centimeters higher than the ground.
Planting in spring will result in flowering in the same year, while planting in autumn will start flowering from the following April to May. Red flower oxalis grows rapidly, and generally, newly planted seedlings can be divided and propagated again in 1-2 years if there is sufficient fertilizer and water. The survival rate is higher when planted in February to March in spring and October to November in autumn. Water promptly after planting, avoiding large-scale flooding as the seedlings are small and shallow. Sprinkler irrigation is better. Water every 3-4 days, for a total of 4 times, and then extend the interval, keeping the ground moist but not waterlogged, otherwise, it will cause root rot.
III. Field Management
Remove weeds in the field in a timely manner. After the plants grow new roots, if the seedlings are not growing well, a small amount of compound fertilizer can be applied, at 40 kilograms per mu each time, using furrow application with a depth of about 10 centimeters. After applying, cover with soil and water thoroughly. Apply again after one month to make the red flower oxalis grow strong, with lush stems and leaves, bright flowers, and enhanced ornamental value.
IV. Disease and Pest Control
Red flower oxalis has fewer diseases and pests, but it is easily affected by red spider mites, especially in dry and stuffy weather in summer. Plants infested with red spider mites have yellowing stems and leaves, leaf drop, and poor growth. It is not easy to detect in the early stages, and by the time it is noticed, it is usually quite severe, so prevention is key. Keeping the ground moist and well-ventilated is crucial. Red spider mites usually infest the back of leaves, and immediate treatment should be applied once detected to prevent widespread damage. Use 20% trichlorfon emulsion 1000 times solution, 50% mitacuron 1000-2000 times solution, or 15% sanmite 1000 times solution, and spray in the afternoon on sunny days, once every 3 days, for 3-5 times to eliminate them.
The above comprehensive introduction to how to plant red flower oxalis, cultivation techniques, and maintenance is hoped to bring some knowledge about green plants to green plant enthusiasts.
