How to propagate Dracaena deremensis by cuttings? Detailed method introduction
The suitable time for cutting propagation of Dracaena deremensis is generally between March and October. When cutting, place the cuttings with the buds facing up, insert them into the bed at a slight angle, and the insertion depth should be about 1/2-2/3 of the cutting.
Management after cutting of Dracaena deremensis
After cutting, water thoroughly immediately. The water content of the cutting medium is best at around 60%, and the relative humidity should be maintained between 80%-90%, taking care to replenish water in time. Callus tissue generally forms after about half a month, at which point, in order to promote rooting, you can begin to gradually reduce the amount of watering.
It is best to keep the air temperature 3-6°C lower than the medium temperature; plastic film and the like can be used for cooling and moisture retention. The suitable temperature for cutting rooting is about 20-25°C. If the temperature is above 30°C, ventilation is needed at noon, along with water spraying to cool down.
After cutting, spray with 65% mancozeb, or 50% carbendazim 800 times solution, generally spraying once every 5 days, and especially remember to re-spray promptly after rain. After the cuttings root, the number of sprayings can be gradually reduced. After callus tissue forms, foliar topdressing is needed once a week, and later a mixed spray of 0.2%-0.5% urea and monopotassium phosphate can be applied.
Cultivation techniques for Dracaena deremensis cuttings
After the cuttings have grown for half a year, when their length reaches about 15-20 cm, they can be transplanted. Transplanting is generally done in spring and autumn, with suitable times between February-May and September-October. When transplanting, choose a location with 60%-70% shade density, a water source, and rocky ground covered with moss for planting, which can improve the survival rate. Generally, it is best to cultivate using the clamp-nail method, pressing the roots of Dracaena deremensis firmly with steel nails, then tidying up the area around the roots, retaining other moss, increasing moisture content, and thereby improving the survival rate.
Dracaena deremensis cultivation methods and precautions, Dracaena deremensis cutting propagation techniques
Dracaena deremensis is a very good indoor plant; it not only has an excellent decorative effect but can also absorb indoor formaldehyde. So how do you care for a home Dracaena deremensis? Let's take a look at the cultivation methods and precautions for Dracaena deremensis as well as cutting propagation methods.
I. How to care for Dracaena deremensis
Dracaena deremensis is suitable for growing in a high-temperature, humid, half-day-shade environment. Because it does not have high sunlight requirements, under indirect light it can keep buds tender and leaves green, with leaves flat and long, resembling banana leaves but smaller. In addition, Dracaena deremensis is suitable for planting in culture soil, and well-drained sandy loam can be used. The optimal growth temperature is between 20°C and 30°C, and in winter it must not go below 10°C.
II. Cultivation methods for Dracaena deremensis
First, we need to prepare the substrate for planting Dracaena deremensis. You can use loose, well-drained, and well-aerated imported peat of the Klassmann 5-40 mm specification, mix the peat with water evenly, and wait to plant it in cups. A 14 cm pot uses about 400 ml of peat per pot, and one 300-liter package of imported peat can fill about 750 cups.
Then choose high-quality professionally produced seedlings, with a seedling height of 11 cm and a crown width of 7-8 cm, free of pests and diseases, dead leaves, and yellow leaves. When potting, generally use a pot with a diameter of 14 cm. When planting, first place about 2 cm of substrate at the bottom of the cup, then move the screened seedlings into the cup. Small seedlings should not be planted too deep, and it is best to keep them level with the base of the plant; the substrate should be moderately firm, filled to 9/10 of the cup.
What remains is routine care. Dracaena deremensis does not have a large demand for water; generally, watering should follow the principle of watering when dry and stopping when wet; Dracaena deremensis grows relatively slowly and has a relatively low demand for fertilizer. In the first 3 to 4 months after planting, because the root system is not well developed, watering with water-soluble fertilizer once every half a month is generally enough. If too much fertilizer and water are used, it will instead be detrimental to the growth of Dracaena deremensis.
III. Precautions for cultivating Dracaena deremensis
1. Potted production standard: 14 cm pot, height 35 cm, crown width about 40 cm, market cycle 7-8 months.
2. Substrate preparation: use loose, well-drained, and well-aerated imported peat of the Klassmann 5-40 mm specification, mix the peat with water evenly (standard for adding water: after mixing with water, squeeze a handful of peat tightly, and water seeps out from between the fingers). Wait to plant it in cups. A 14 cm pot uses about 400 ml of peat per pot, and one 300-liter package of imported peat can fill about 750 cups.
3. Requirements for potting seedlings: choose high-quality professionally produced seedlings, with a seedling height of 11 cm and a crown width of 7-8 cm, free of pests and diseases, dead leaves, and yellow leaves.
4. Cup planting: for old pots that are reused, they must be soaked in 1000 times potassium permanganate solution for more than half an hour, then rinsed with clean water and dried for later use. Generally use a pot with a diameter of 14 cm. When planting, first place about 2 cm of substrate at the bottom of the cup, then move the screened seedlings into the cup. Small seedlings should not be planted too deep, and it is best to keep them level with the base of the plant; the substrate should be moderately firm, filled to 9/10 of the cup.
IV. Cutting method for Dracaena deremensis
The time is preferably March-October. Insert the cuttings into the bed with the buds facing up and at a slight angle, with a depth of 1/2-2/3 of the cutting.
Management after cutting
Humidity of the cutting bed. The water content of the cutting medium should be maintained at about 60%, and the relative humidity should be maintained at 80%-90%, with timely water replenishment. After callus tissue forms in about 15 days, gradually reduce the amount of watering to facilitate rooting, and ventilate for 1-2 hours every day.
Watering the cutting bed. Immediately after cutting, water thoroughly once, keep the air temperature 3-6°C lower than the medium temperature, use plastic film or a shade net to cool and retain moisture, and generally the air temperature suitable for cutting rooting is 20-25°C. If the temperature exceeds 30°C, ventilate at noon and spray water to cool down.
Pesticide application and fertilization for the cutting bed. After cutting, promptly spray 50% carbendazim 800 times solution or 65% mancozeb, once every 5 days, and especially re-spray promptly after rain. After the cuttings root, the number of sprayings can be appropriately reduced. After callus tissue forms, apply foliar topdressing once a week, and later use a mixed spray of 0.2%-0.5% urea and monopotassium phosphate.
