Method for Cutting the Top of Euphorbia Obesa
Euphorbia obesa, as a popular species in the succulent family, is loved by gardening enthusiasts for its unique stem shape. However, many beginners often damage the plant due to improper pruning techniques when dealing with overgrown Euphorbia obesa. This article will systematically explain the correct method for cutting the top of Euphorbia obesa, helping you achieve dual goals of shaping control and propagation through cuttings.
Ⅰ. Core Steps for Pruning Euphorbia Obesa
1. Preparation of Professional Tools
It is recommended to use a single-edged craft knife or surgical blade, as its sharp edge can ensure a smooth incision. Special note: Scissors can cause compressed damage to the xylem, and the blade surface should be disinfected with 75% alcohol or fire before use to avoid bacterial infection.
2. Accurate定位 for Cutting the Top
Observe the growth direction of the main stem and choose a position with leaf scars 5-8 centimeters from the top. The best time for topping is in the morning during the spring and autumn growing seasons, when the plant cells are active and conducive to the formation of healing tissue.
3. Standard Operating Technique
Hold the knife at a 45-degree angle and cut quickly to ensure a smooth, burr-free incision. Immediately after, use a cotton swab to apply a fungicide powder to the wound surface to form an antibacterial protective layer.
Ⅱ. Scientific Care After Topping
1. Key Points for Environmental Control
Place it in a well-ventilated area with diffused light, maintaining a temperature between 18-25℃. Strictly avoid water for the first 3 days, and only resume a small amount of watering after the incision has completely healed.
2. Techniques to Promote Sprouting
Two weeks later, spray the stem with a diluted gibberellin solution (1000 times), which can effectively stimulate the sprouting of lateral buds. Combined with the application of phosphorus and potassium fertilizer every month, it can make the distribution of new branches more uniform.
Ⅲ. Guidelines for Cutting and Propagating Branches
1. Pre-treatment of Cuttings
Place the cut branches in a shaded place for 48 hours to allow the incision to form a white callus layer. Remove the basal leaves and retain only the top 3-4 leaves to reduce transpiration.
2. Suggested Substrate Formula
Use a mixed substrate of perlite: vermiculite: peat in a ratio of 2:1:1, which has good breathability. The cutting depth should be about 2-3 centimeters, maintaining the medium slightly moist, and new roots can be seen in about 3 weeks.
Through scientific topping pruning, not only can the elegant shape of Euphorbia obesa be重塑ed, but it can also achieve the effect of multiplying one plant into many. Mastering the three core points of disinfection protection, precise cutting, and environmental control, even gardening beginners can easily complete this shaping project.
