How to grow Pedilanthus tithymaloides? Detailed guide to cultivation methods

Light

Pedilanthus tithymaloides does not have very high light requirements and needs no special attention. Moreover, under strong light its leaves take on a reddish hue, while in partial shade they turn greener, and both look very attractive. But remember not to let Pedilanthus tithymaloides receive direct strong sunlight in summer, and indoors do not place it in too dark a spot either.

Temperature

Pedilanthus tithymaloides likes warmth, and room temperature in all three seasons of spring, summer and autumn is suitable for its growth. However, in winter when the temperature falls below about 13°C the leaves turn white and then drop off. When the ambient temperature is below 8°C it stops growing, so we want to tell everyone to provide our Pedilanthus tithymaloides with a comfortable temperature in winter so it can keep growing.

Watering

Pedilanthus tithymaloides is a succulent plant with fairly strong drought tolerance, so during its growing season we only need to water once half of the potting soil has dried out. In winter, just water a small amount when the potting soil is dry. But be sure not to water too much, as this causes mildew, and in more serious cases rot at the base of the stem.

Humidity

Pedilanthus tithymaloides rather likes a moist environment, and we need to create growing conditions with relative air humidity of 50-70% for it. This is because when the relative air humidity is too low, its lower leaves turn yellow and drop off, while the upper leaves lose their gloss.

Fertilizing

During the growing period, a compound fertilizer can be applied to the plant once a month, which lets Pedilanthus tithymaloides grow better.

Pruning

In winter the plant begins to enter dormancy or semi-dormancy, and we should help it by cutting off weak, overly dense, dead and pest- or disease-affected branches. Of course, you can also tidy up the branches in combination with taking cuttings.

Cultivation methods for Pedilanthus tithymaloides

1. Key care points

Pedilanthus tithymaloides likes warmth and tolerates drought, with an optimum growing temperature of 23°C to 30°C. After being frosted, the leaves turn white and drop off. It tolerates shade, and a semi-shaded cultivation site is favorable for flowering and gives more attractive leaf color. It is afraid of wind and is suited to growing in a dry, windless environment. For the growing medium, a sandy loam with good drainage and aeration should be chosen. Repot once a year or every other year, and when branches are too long, shorten them or set up stakes for support. If there are few branches, prune the branches as appropriate to encourage more side branches.

During the growing period, watering should be controlled, generally watering only after the soil has dried. For fertilizing, organic fertilizer or a small amount of nitrogen, phosphorus and potassium fertilizer can be used. In winter, reduce the amount of fertilizer and water supplied. Pedilanthus tithymaloides is propagated by cuttings. In a greenhouse, cuttings can be taken all year round, but taking cuttings in the warm season is better. Take stem tips or tender stems and cut them into 10 cm long stem sections as cuttings. The cuttings should first be dried, or the cut end inserted into dry ash or dry soil so the sap is absorbed, and then they are inserted for rooting. The medium can be yellow sand, perlite or rice husk ash. Once the cuttings have rooted, they can be transplanted into pots.

2. Daily care

Light: Pedilanthus tithymaloides is not very demanding about light; under strong light the leaves tend toward red, and in partial shade toward green. But do not let direct strong sunlight hit it in summer, and indoors do not place it in too dark a spot either.

Temperature: Pedilanthus tithymaloides likes warmth, and in the three seasons of spring, summer and autumn ordinary room temperature is suitable for growth. In winter, when the temperature falls below about 13°C, the leaves can turn white and drop off.

Watering: Pedilanthus tithymaloides is a succulent plant with fairly strong drought tolerance; during the growing season, wait each time until half of the potting soil is dry before watering. In winter, water a small amount when the potting soil is dry. Too much watering causes mildew, and in more serious cases rot at the base of the stem.

Fertilizing: during the growing period, a compound fertilizer can be applied to the plant once a month.

Potting soil: Pedilanthus tithymaloides is suited to a well-drained, loose and fertile sandy loam.

Propagation: Pedilanthus tithymaloides can be propagated by cuttings using 5-15 cm long stem sections. Like other Euphorbiaceae plants, Pedilanthus tithymaloides exudes white milky sap as soon as it is cut; if the cut end is dipped in water, this can be stopped. The cuttings should be dried in the shade for a day, and once the cut end has dried and sealed, they can be inserted into the medium.

Growing techniques for Pedilanthus tithymaloides

Potted Pedilanthus tithymaloides needs repotting once a year or every other year, carried out before it is moved outdoors in spring; the potting soil is usually a mix of equal parts pond mud, leaf mold and sand. The pot should also be chosen a little smaller than a normal pot, and if conditions allow, a layer of charcoal can be placed at the bottom of the pot to improve drainage. Normally, do not water too much; it should be kept on the dry side, and watered only after the soil has dried through. It is best to have 3 hours of light each day. Pedilanthus tithymaloides has high fertilizer requirements; during the growing season, applying a dilute fertilizer 1-2 times a month is enough. In winter, move it indoors and keep it above 5°C and it will overwinter safely; at this time, do not let the humidity be too high, otherwise the roots rot easily.

The cultivation site for Pedilanthus tithymaloides should be ventilated and let light through, and the humidity must not be too high. Water normally during the growing period, but not too wet, and apply fertilizer as appropriate according to the plant's growth. As long as the leaf color is normal and the stems are green and fresh, no fertilizer is needed. Shade it in summer and avoid scorching sun exposure. In winter the plant is in a semi-dormant state; at this time keep the potting soil dry, place it in a sunny spot indoors, and maintain room temperature at 10°C, and it should not be too high. Repot every spring, and when repotting add some new fertile growing soil. Prune often to encourage branching and develop a full plant shape.

1. Humidity management

It likes a moist or semi-dry climate environment and requires the relative air humidity of the growing environment to be 50-70%; when the relative air humidity is too low, the lower leaves turn yellow and drop off, and the upper leaves lose their gloss.

2. Temperature management

Because it originates from subtropical regions, it has very strict requirements for winter temperature; when the ambient temperature is below 8°C it stops growing.

3. Light management

It has fairly strong adaptability to light. When keeping it indoors, place it in a spot with bright light as much as possible, such as a well-lit living room, bedroom or study. After keeping it indoors for a period (about one month), move it outdoors to a shaded spot (with winter insulation conditions) for a period (about one month), and alternate in this way.

4. Fertilizer and water management

For potted plants, in addition to adding organic fertilizer when potting, appropriate fertilizer and water management should also be carried out during normal care. Spring, summer and autumn: these three seasons are its peak growing period, and fertilizer and water management follows the cycle of "Hua Bao" - clear water - "Hua Bao" - clear water, with intervals of about 1-4 days; the interval is shorter on sunny days or during high temperatures, and longer or no watering on rainy days or during low temperatures. Winter: during the winter dormant period, the main task is to control fertilizer and water, and fertilizer and water management follows the cycle of "Hua Bao" - clear water - clear water - "Hua Bao" - clear water - clear water, with intervals of about 3-7 days; the interval is shorter on sunny days or during high temperatures, and longer or no watering on rainy days or during low temperatures.

For plants grown in the ground, in spring and summer apply fertilizer and water 2-4 times according to drought conditions: first dig a small ring trench 30-100 cm outside the root crown (the larger the plant, the farther from the root crown), with the trench 20 cm wide and 20 cm deep. Spread 25-50 jin of organic fertilizer, or 1-5 liang of granular compound fertilizer (chemical fertilizer), into the trench, then water thoroughly. After winter begins and before spring begins, apply fertilizer once more in the above manner, but without watering.

5. Pruning

In winter, when the plant enters dormancy or semi-dormancy, cut off weak, pest- or disease-affected, dead and overly dense branches. You can also tidy up the branches in combination with taking cuttings.

6. Repotting

As long as it is cared for properly, it will grow very fast; when it has grown to a certain size, consider giving it a larger pot so it can continue to grow vigorously. For the growing soil used for repotting, one of the following component ratios can be chosen: vegetable garden soil: furnace slag = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud or leaf mold.

7. Removing from the pot

Place the flower to be repotted on the ground, first tap lightly around the pot with the palm of your hand so the root system is shaken and separates from the pot wall, then turn the pot upside down and place it on your left hand, with the index and middle fingers of your left hand gently holding the plant, your wrist and fingertips braced against the pot rim, while your right hand pats the bottom of the pot, then use your thumb to push the root soil downward from the bottom hole so the plant comes out. After it comes out, pat the potting soil lightly with both palms so excess soil falls away.

8. Preparing the pot

Choose a pot of appropriate size, and cover the bottom hole with two pieces of broken tile or thin foam pieces, ensuring both that the potting soil is not washed out by water and that excess water can drain out in time. On top of the tile or foam, place a layer of expanded clay pellets or crushed red brick as a drainage layer, about 2-3 cm thick. On the drainage layer, place organic fertilizer, about 1-3 cm thick, and on the fertilizer place a thin layer of medium, about 2 cm thick, to separate the root system from the fertilizer; finally put the plant in, fill with nutrient soil, leaving about 2-3 cm to the pot rim.

Propagation methods for Pedilanthus tithymaloides

Pedilanthus tithymaloides is mainly propagated by cuttings, which can be done all year round in a greenhouse, with May and June being the best. Take stem tips with 2-3 nodes and about 8 cm long, wait for the milky sap at the cut end to dry and the cutting to shrink slightly, then insert it into a medium such as sand; the medium must have a certain moisture level. After inserting, do not water for the time being, and do not cover with plastic film; place it in partial shade, water thoroughly once after 2 days, then keep it slightly moist, and it will root in about 40 days.

Pedilanthus tithymaloides is mostly propagated by cuttings; in spring cut off sections with the top branches as cuttings, smear the cut surface of the cut cuttings with charcoal powder or scorch it with fire, and insert into sandy soil. The cutting medium must have a certain moisture level, and the insertion depth is one half of the cutting. After inserting, do not water for the time being; water thoroughly once after two days, and it can root in about 30-45 days.

1. Seed propagation

For very small seeds that are hard to pick up with your hands or other tools, you can moisten one end of a toothpick with water and stick the seeds one by one onto the surface of the medium, then cover with 1 cm of medium, then place the sowing pot into water with the water depth at 1/2 to 2/3 of the pot height, letting the water slowly soak up (this method is called the "pot immersion method"); for larger seeds that can be picked up with your hands or other tools, place the seeds directly into the medium and sow them in spots at a spacing of 3×5 cm. After sowing, cover with medium to a thickness of 2-3 times the size of the seeds. After sowing, use a sprayer or a fine-holed watering can to moisten the sowing medium, and later water again when the potting soil is slightly dry; still be careful not to water too forcefully, so as not to wash the seeds out;

Before sowing, the seeds must first be selected; whether the seeds are chosen well or not directly affects whether sowing will succeed.

1. It is best to use seeds collected in the same year. The longer the seeds are stored, the lower their germination rate.

2. Choose seeds that are plump and free of damage or deformity.

3. Choose seeds free of pests and diseases.

Disinfection: Disinfection includes two concepts, one referring to disinfecting the seeds and the other referring to disinfecting the sowing medium. For household seed disinfection, it is common to soak the seeds in hot water at about 60°C for a quarter of an hour, then use warm hot water to promote germination for 12-24 hours. To disinfect the sowing medium, the best method is to put it in a pot and heat it by stirring until hot; any pest or disease will be killed by the heat.

Promoting germination: Soak the seeds in warm hot water (at a temperature similar to face-washing water) for 12-24 hours, until the seeds absorb water and swell. For very common seeds that germinate easily, this step can be skipped.

Management after sowing: After sowing in late autumn, early spring or winter, when cold waves and low temperatures occur, you can wrap the pot in plastic film to help keep it warm and moist; after the seedlings emerge, uncover the film in time, and let the seedlings receive sunlight before 9:30 every morning, or after 3:30 in the afternoon, otherwise the seedlings will grow very weak; after most of the seeds have come up, thin the seedlings appropriately: pull out the diseased and unhealthy seedlings so the remaining seedlings have a certain space between them; when most of the seedlings have grown 3 or more leaves, they can be transplanted.

2. Cutting propagation

Softwood cuttings are usually taken in late spring and early autumn using branches of the current year, or hardwood cuttings are taken in early spring using branches from the previous year.

1. Cutting medium

This refers to the nutrient soil, river sand, peat soil and other materials used for cuttings. For household cuttings, ideal cutting media are hard to obtain due to limited conditions; medium-coarse river sand can also be used, but it must be rinsed several times with clean water before use. Do not use sea sand or river sand from saline-alkali areas; they are not suitable for the growth of flowering plants.

2. Selection of cuttings

When taking softwood cuttings, in the period from late spring to early autumn when the plant grows vigorously, choose robust branches of the current year as cuttings. After cutting off the branch, select the sturdy part and cut it into sections 5-15 cm long, each section bearing more than 3 leaf nodes. When cutting the cuttings, note that the upper cut should be made flat about 1 cm above the topmost leaf node, and the lower cut should be made at an angle about 0.5 cm below the bottommost leaf node, with both upper and lower cuts smooth (the knife must be sharp). When taking hardwood cuttings, after temperatures rise in early spring, choose robust branches from the previous year as cuttings. Each cutting usually retains 3-4 nodes, and the cutting method is the same as for softwood cuttings.

3. Management after cutting

Temperature: The optimum temperature for cutting rooting is 20°C-30°C; below 20°C, the cuttings root with difficulty and slowly; above 30°C, the upper and lower cuts of the cuttings are easily infected by pathogens and rot, and the higher the temperature, the greater the proportion of rot. When low temperatures occur after cutting, the main measure to keep warm is to wrap the pot or container used for cutting in plastic film; when the temperature is too high after cutting, the main measure to cool down is to shade the cuttings, blocking out 50-80% of the sunlight, and at the same time spray the cuttings 3-5 times a day; on sunny days with higher temperatures, spray more often, and on rainy days with lower temperatures and higher humidity, spray less often or not at all.

Humidity: After cutting, the relative air humidity must be kept at 75-85%. The basic requirement for cutting rooting is that before the cuttings root, they must be kept fresh and tender so they can carry out photosynthesis to produce rooting substances. But cuttings that have not rooted cannot absorb enough water to maintain their internal water balance, so the water evaporation of the cuttings must be reduced by spraying: under shaded conditions, spray the cuttings 3-5 times a day; the higher the temperature on sunny days, the more often you spray, and the lower the temperature on rainy days, the less often you spray or not at all. But excessive spraying makes the cuttings easily infected by pathogens and rot, because many kinds of pathogens exist in water.

Light: Cutting propagation cannot do without sunlight, because the cuttings still need to carry out photosynthesis to produce nutrients and rooting substances to supply their rooting needs. However, the stronger the light, the higher the temperature inside the cuttings, the more vigorous the transpiration of the cuttings, and the more water consumed, which is not favorable for the survival of the cuttings. Therefore, after cutting, 50-80% of the sunlight must be blocked out, and after the root system grows, gradually remove the shade net: on sunny days remove the shade net at 4:00 every afternoon, and put the shade net back before 9:00 the next morning.

3. Layering propagation

Select a robust branch and remove a ring of bark about 15-30 cm below the top tip; the width of the wound after removal is about 1 cm, and the depth is limited to just removing the outer bark. Cut a piece of plastic film 10-20 cm long and 5-8 cm wide, put some moistened garden soil on it, and wrap up the girdled part as if bandaging a wound, tying the upper and lower ends of the film tightly with the middle bulging. It roots in about four to six weeks. After rooting, cut off the branch together with the root system, and it becomes a new plant.

1. Potting or transplanting

When potting small seedlings or repotting large plants that have been grown for several years, first place a 2-3 cm thick layer of coarse medium at the bottom of the pot as a drainage layer, sprinkle a layer of fully decomposed organic fertilizer on it as base fertilizer, about 1-2 cm thick, then cover with a thin layer of medium, about 1-2 cm thick, and then place the plant in, so as to separate the fertilizer from the root system and avoid burning the roots. For the medium used for potting, one of the following can be chosen: vegetable garden soil: furnace slag = 3:1; or garden soil: medium-coarse river sand: sawdust (mushroom residue) = 4:1:2; or one of paddy soil, pond mud or leaf mold. After potting, water thoroughly once and keep it in a shaded environment for a week. When transplanting small seedlings, first dig the planting hole, sprinkle a layer of organic fertilizer at the bottom of the planting hole as base fertilizer (bottom fertilizer), about 4-6 cm thick, then cover with a layer of soil and place the seedling in, so as to separate the fertilizer from the root system and avoid burning the roots. After placing the seedling in, backfill the soil to cover the root system, firm the soil with your foot, and water thoroughly once.
