Light Requirements
Tetragonia rosea Schltr. prefers bright, direct sunlight and can tolerate some shade, but plants grown in shadier conditions may produce fewer flowers.
Temperature Requirements
This plant thrives in warm temperatures between 18°C and 27°C. It is important to protect the plant from frost or temperatures below 10°C, which can damage or kill the plant.
Soil Requirements
Tetragonia rosea Schltr. grows best in well-draining soil that is sandy or loamy. The soil should be slightly acidic to neutral, with a pH of 6.0 to 7.5. It is also important that the soil be rich in organic matter and have good moisture retention as the plant does not tolerate drought well.
Cultivation
Tetragonia rosea Schltr. plants grow well in well-draining soil with a pH between 6.0 and 7.5. It is an ideal plant for areas with full sunlight, and the soil has to be rich in nutrients. The best planting time is during the rainy season when the soil is moist.
Watering
The plant requires regular watering to maintain moisture levels in the soil but should not be over-watered. For container plants, water the plant frequently but avoid letting the soil become overly saturated. For plants in the ground, irrigation should be maintained at least once or twice each week, depending on the climate and soil conditions.
Fertilization
Fertilization of Tetragonia rosea Schltr. plants should be done with organic compost or well-rotted manure to provide the necessary nutrients for growth. Application of fertilizer should be done during the growing season in small quantities to prevent excess nitrogen levels, which may reduce the fruit's quality and quantity.
Pruning
Pruning Tetragonia rosea Schltr. plants helps maintain their shape and controls their growth. The ideal time to prune the plant is during the semi-dormant season where a cut of about 40-50% of the branches should be done. This encourages new growth and ensures the plant does not become too large and difficult to maintain. In addition, it is essential to remove any dead or weakened branches to prevent the spread of disease and fungi.
Propagation of Tetragonia rosea Schltr.
Tetragonia rosea Schltr. can be propagated through both seeds and cuttings.
Seed Propagation
To propagate Tetragonia rosea Schltr. from seeds, sow the seeds in well-drained soil, preferably a mixture of garden soil and sand. The seeds should be sown about 1-2 cm deep in the soil.
The soil should be kept moist but not waterlogged. Germination usually takes about two weeks to one month, depending on the soil temperature, which should be around 20-25°C.
Transplant the seedlings into individual pots once they have their first true leaves and are large enough to handle. Once the plants have outgrown their pots, they can be planted in the field or be transplanted into larger containers.
Cutting Propagation
Tetragonia rosea Schltr. can also be propagated through stem cuttings either in water or in rooting media.
Select healthy cuttings with at least two to three nodes. Cut the stem at an angle with a sharp, sterilized scissor, just below a node. Remove any leaves on the lower part of the stem leaving only two to three leaves on the upper portion.
If propagating in a rooting medium, dip the cutting into rooting hormone and insert it into the prepared medium. Keep the medium moist, but not waterlogged, and in a warm, bright location, preferably with some partial shade.
If propagating in water, insert the cutting into a jar or container filled with water. Change the water regularly to avoid algae growth and keep the cutting in a bright, warm location with some partial shade.
Once the cutting develops roots and new growth, transplant it into a pot or the field.
Disease Management
The plant Tetragonia rosea Schltr. is susceptible to several diseases such as fungal leaf spots, root rot, and powdery mildew. These diseases can cause significant damage to the plant, leading to stunted growth or death. Implementing a few cultural practices can help prevent and manage these diseases. Firstly, maintain proper soil drainage to avoid root rot. Secondly, avoid overhead watering as it encourages the spread of fungal leaf spots and powdery mildew. Lastly, remove diseased plant parts to avoid the spread of the diseases.
Pest Management
Some of the common pests that can damage Tetragonia rosea Schltr. include aphids, spider mites, and whiteflies. These pests can cause yellowing of leaves, wilting, and stunted growth. The use of pesticides may damage the plant, and it is, therefore, advisable to use natural methods of pest management. You can use a mixture of water and detergent soap to eradicate aphids and spider mites. Whiteflies can be controlled by using sticky traps. Additionally, you can introduce beneficial insects such as ladybugs, lacewings, and parasitic wasps to control pest infestation.
