How to propagate Oxalis purple leaf by cutting
The editor explains how to propagate Oxalis purple leaf by cutting and offers some tips on caring for flowers. Here is a comprehensive introduction.
There are many types of Oxalis, including purple leaf Oxalis, red flower Oxalis, variegated Oxalis, and Oxalis with Rumex leaves, among others. For home cultivation of Oxalis potted plants, most people choose the purple leaf variety. The purple leaf Oxalis has purple leaves and can greenify the environment and decorate the room when planted in living spaces. The propagation methods for Oxalis include division and cutting propagation, with the latter being commonly used in home cultivation. Let's talk about the cutting propagation method for Oxalis.
I. Cutting Time
Propagation by cutting can be done throughout the year, but the best results are achieved in spring and autumn. This is because these seasons are the peak growing periods for Oxalis, and the survival rate after cutting is higher.
II. Selecting Cuttings
First, select some healthy leaves that have not been affected by diseases or pests. Then, cut branches from the mother plant, with each branch about 9 cm long. After cutting the branch, trim the lower part and retain one or two leaves at the top. The cut should be properly disinfected. The bottom of the branch should be coated with some rooting powder.
III. Preparing the Substrate
The soil should be loose and fertile, with good drainage and a pH value that is neutral to acidic. Many gardening enthusiasts prepare their own nutrient-rich soil, which is a mixture of peat, perlite, and vermiculite. You can choose a ceramic pot or a clay pot. After preparing the nutrient-rich soil, fill the pot with soil and ensure it is properly disinfected.
IV. Performing the Cutting
Insert the prepared cuttings into the soil at an appropriate depth. Then water moderately to keep the potting soil moist and place the Oxalis potted plant in a shaded environment. After about one month, the Oxalis should root and sprout. Once it has grown a few leaves, it can be transplanted.
V. Daily Maintenance
1. Temperature Conditions
Keeping the temperature between 16°C and 22°C is most conducive to the growth of Oxalis, as this plant prefers a warm and humid environment. The temperature in winter should be above 5°C. If the temperature exceeds 35°C in summer, the plant will enter a dormant period. Appropriate shading is required during the summer.
2. Light Conditions
Oxalis plants require full sunlight in spring and autumn, and need appropriate shading from May to September. If growing Oxalis on a balcony or near a window, the plant should be rotated frequently to ensure even exposure to light.
3. Watering Conditions
During the growing season of Oxalis, follow the principle of watering only when the soil is dry. In summer, when temperatures are high, keep the potting soil slightly moist. In winter, when temperatures are below 10°C, water should be controlled.
Allowing the plant to receive some rain is beneficial for its growth. However, ensure there is no waterlogging in the pot and proper drainage is maintained.
4. Humidity Conditions
Oxalis prefers a humid environment. If the growing environment is too dry, some water should be sprayed around the plant to increase air humidity.
5. Fertilizing Conditions
When potting, sufficient base fertilizer should be applied. During the growing season, apply a nitrogen-phosphorus-potassium compound fertilizer once a month, with a light concentration and small amount. From July to August, no fertilizer should be applied. When fertilizing Oxalis, avoid using single-type fertilizers. Liquid fertilizers should not splash on the leaves to prevent leaf diseases.
6. Appropriate Pruning
If the plant grows too vigorously, overly dense branches and leaves should be pruned.
Regularly observe the plant's growth, remove yellow leaves, and cut back long petioles if necessary.
7. Regular Potting
Repot Oxalis every spring, using fresh potting soil that is loose, fertile, and has good drainage with a pH value that is neutral to acidic.
8. Pest and Disease Prevention
During the growth of Oxalis, various diseases can occur, such as leaf spot, gray mold, root rot, and aphids. For different diseases, apply the appropriate liquid medication promptly.
