The plant grows best in moist to moderately dry soil that is free from any stagnation of water. Sandy loam or loamy soil is ideal for the plant's growth. The soil should also be free of weeds so that the plant does not have to compete for nutrients. It is recommended to prepare the soil by organic manuring and mulching to improve soil quality and sustainability.
Temperature Requirements
The Ipomoea macrorhiza Michx. plant can survive in both tropical and sub-tropical regions. The plant is hardy in USDA zones 7-10, where temperatures range from -18 to 40°C. The plant can withstand occasional frost, but severe frost can damage the roots and cause the plant's death. The optimal temperature for the plant to grow is between 21-30°C. High-temperature stress may affect the plant's growth and yield adversely.
Cultivation Methods of Ipomoea macrorhiza Michx.
Ipomoea macrorhiza Michx., commonly known as the Man of the Earth or the Manroot, is a plant species that belongs to the Convolvulaceae family. The plant can be cultivated with ease in a garden or a container.
The best planting season for Man of the Earth is between late fall and early spring. Ensure that the soil is fertile, well-drained, and slightly acidic. The seeds of the plant should be sown at least one inch deep into the soil, and they should be spaced two to three inches apart. Water the soil right after planting.
Man of the Earth thrives in full sun but can also tolerate partial shade. Make sure the plant is protected from strong winds and frost. The plant has a large root system that can go as deep as five feet, so ensure it is planted in an area where there is enough space for the roots to grow.
Watering Needs
The Man of the Earth plant requires enough water to enable the soil to remain consistently moist but not waterlogged. Water the plant frequently, especially during the growing season, and reduce watering in winter.
It is advisable to use a watering can or drip irrigation system to water the plant at the base of the plant, ensuring that the foliage remains dry to prevent the growth of fungal diseases. Avoid overwatering as it can cause root rot.
Fertilization
Man of the Earth requires regular fertilization to grow to its full potential. Apply a slow-release nitrogen-based fertilizer every six weeks during the growing season.
If you plant in pots, add some organic matter such as compost before planting to boost soil fertility. Organic matter will also help keep the soil moist and well-drained.
Pruning
There is no need to prune Ipomoea macrorhiza Michx. Man of the Earth plant. The plant has a beautiful, natural shape and does not require shaping or cutting. Removing dead leaves or stems is enough to keep the plant healthy and attractive.
Propagation of Ipomoea macrorhiza Michx.
Ipomoea macrorhiza Michx. is a perennial plant species that has gained significant commercial and ornamental value. The propagation of the species is primarily through seeds, tubers, and stem cuttings.
Propagation through Seeds
Seeds collected from mature fruits are used for propagation. The seeds are cleaned and soaked in water for 24 hours before sowing. The seeds are sown directly into the soil in early spring when the soil is warm enough. Germination usually takes about 14 – 21 days.
Propagation through Tubers
Tubers that are 1–2 cm in diameter are used for propagation. These tubers are planted in well-draining soil during the spring season. The tubers are planted at a depth of 5 cm and spaced about 15 cm apart. After planting, the soil should be kept moist, and watering should be done sparingly until the new shoots emerge.
Propagation through Stem Cuttings
Stem cuttings are used for propagation only when the plant is actively growing. Cuttings of 10–15 cm in length are taken from well-developed stems, with at least two leaves attached to each cutting. These cuttings are planted in a well-draining potting mix. The cuttings are kept moist and shaded for two weeks until they are established. Afterward, the cuttings can be transferred to their final location.
