How to Propagate Dracaena Reflexa: Roots in Half a Month from Cuttings, Key Points for Seed Sowing and Seedling Raising
Dracaena reflexa, also known as short-leaf dragon tree, is an evergreen shrub of the genus Dracaena in the Agavaceae family. Its leaves have golden stripes, and a pot grown in water placed in the living room or office looks very upscale. If you want to grow a few more pots, you don't need to buy them; just propagate them yourself. How to propagate Dracaena reflexa? Two methods are commonly used: cuttings and sowing. For home gardening, cuttings are recommended; for large-scale seedling production, choose sowing.
Cutting Propagation: Simple to Do, Roots in About Half a Month
Cuttings are best taken in spring from March to May, or in autumn. During these two periods, the plant has strong vitality and a high rooting rate. Cut current-year mature branches from a healthy mother plant as cuttings, 8-10 cm long; keep 3-4 buds on hard stems, and keep 3-4 leaves on soft branches. If there are many leaves on the branch, you can cut off more than half, or even all of them, to reduce water consumption.
For the substrate, clean coarse river sand is best, as it has strong permeability and is especially good for rooting; sterilized loose sandy loam or peat soil also works. Insert the cuttings into the substrate, water thoroughly, cover with a plastic bag to keep warm and moist, and place in a bright indoor spot. After that, spray water 1-2 times a day for 3-5 minutes each time. With this management, they generally root in 15-25 days. If inserted in water and kept at around 25°C, roots can grow in about 15 days. For faster and more reliable rooting, you can use a "Root Sun" rooting agent at 400 times dilution mixed with yellow mud to make a slurry, dip the cut end of the cutting into the slurry, and after the slurry dries, insert it into the seedbed. When inserting, first make a hole with a stick and then insert the seedling to prevent the slurry from falling off, and roots will form in about 20-25 days.
Sowing Propagation: Suitable for Mass Seedling Production
Dracaena reflexa can set seeds after flowering, and sowing can be done in both spring and summer. Before sowing, both the soil and seeds must be sterilized: sterilize the soil with 70% thiophanate-methyl, then kill insects with 90% trichlorfon; soak the seeds in a 0.5% potassium permanganate solution for 30 minutes, then remove them after they swell with water, dry them, and sow. Seeds can be sown as soon as collected, or stored until spring and summer for sowing.
The sowing bed is made by mixing nutrient soil, leaf mold, and river sand in equal parts. Scatter the seeds on the bed surface, keep the soil moist, and control the room temperature at 20-25°C; seedlings emerge in about 25-30 days. When the seedlings grow to 3-5 cm, weed and thin them in time, and combine this with fertilization: every 7-10 days, apply a dilute mixture of 3%-5% human manure and urine plus 1%-2% decomposed cake fertilizer; afterward, pour a 0.5%-0.8% compound fertilizer solution around the seedling roots, being careful not to pour it on the leaves. After fertilizing, sprinkle a little water on the leaf surface to avoid burning the leaves.
Potting, Transplanting, and Daily Care
When the seedling root system grows to 3-5 cm, transplant them into pots in time. If potted too late, the seedlings will grow weaker and later growth will be affected. When transplanting, keeping the soil ball gives a higher survival rate, and after planting, keep the soil moist.
For daily care, remember a few points: Dracaena reflexa likes warmth and humidity, with an optimum growth temperature of 20-28°C. In winter, it is best to keep it above 10°C; below 5°C it is prone to freezing damage. The suitable air humidity is 75%-85%; if it is too dry, the leaf tips will wither and turn yellow. It likes light but dislikes direct summer sun, so placing it by a south window or on a balcony with slight shading is enough. With insufficient light, the golden stripes on the leaves will darken and disappear. It is not fussy about watering and tolerates both drought and moisture; just water thoroughly after the top layer of potting soil dries. Alternating dry and wet conditions can make the internodes compact and the plant shape attractive. When the seedlings grow to 8-10 cm, pinch the tips once, and when the new shoots grow to 4-6 cm, pinch again. After repeating this several times, the plant shape becomes full.
To sum up: cuttings are simple and fast, showing roots in about half a month, and are most suitable for home operation; sowing is suitable for mass seedling production, but the cycle is a bit longer. Once you learn the methods, propagating Dracaena reflexa is actually not difficult at all.
