This plant prefers loamy soil, but it's also capable of growing in other types of soil as long as the drainage is efficient. It's advisable to fertilize the soil before planting and add more nutrients to the soil once in a while for optimum growth conditions.
Cultivation of Campuloa hirsuta Desv.
Campuloa hirsuta Desv. thrives well in well-drained soils with a pH range of 6.0-7.0. The plant prefers full sun or partial shade, and it can be grown in pots and containers or planted directly into the ground.
Watering Needs
The Campuloa hirsuta Desv. plant requires frequent watering during the growing season, especially during prolonged dry periods. However, excess water can lead to root rot. Therefore, it is vital to ensure that the soil is well-drained and moist, but not waterlogged.
Fertilization
Fertilization is essential for the healthy growth of Campuloa hirsuta Desv. The plant requires regular fertilization with a balanced liquid fertilizer every two weeks during the growing season. Additionally, adding organic matter such as compost or manure can be beneficial for the plant's overall health.

Propagation of Campuloa hirsuta Desv.
Campuloa hirsuta Desv. can be propagated by various methods. The most common methods are:
Seed Propagation
Seeds can be sown in containers or directly in soil. It is recommended to use well-draining soil and provide sufficient sunlight. The ideal time for seed sowing is in winter or early spring.
Cuttings Propagation
Softwood cuttings can be taken in spring or summer. It is important to remove the leaves from the lower part of the cutting and dip the cut end in rooting hormone before planting it in a well-draining soil mix. Keep the soil moist and in a warm and humid environment until roots develop.
Division Propagation
Campuloa hirsuta Desv. can be divided in late winter or early spring. Dig up the plant and carefully divide the clumps into smaller sections, making sure each section has some roots attached. Replant the divisions in well-draining soil and keep the soil moist until new growth appears.
Propagation of Campuloa hirsuta Desv. can be successful with any of these methods when proper care is taken and ideal conditions are provided.
Disease Management
Campuloa hirsuta Desv. is generally resistant to most diseases. However, it can be susceptible to root rot caused by excessive watering or poor soil drainage. To manage root rot, make sure the plant soil is well-draining. Avoid over-watering and provide adequate air circulation around the plant to prevent the accumulation of moisture around the roots.
Pest Management
Campuloa hirsuta Desv. attracts very few pests. However, it can occasionally be attacked by spider mites, mealybugs, and scale insects. Infestations can be managed by regularly inspecting the plant and taking appropriate measures once pests are identified.
To manage spider mites, rinse the plant with a strong stream of water or spray with insecticidal soap. For mealybugs and scale insects, remove the pests manually using a cotton swab dipped in alcohol. Neem oil can also be an effective solution for getting rid of these pests.
