Growth Conditions for Sopubia parviflora Engl. subsp. parviflora
Light: Sopubia parviflora Engl. subsp. parviflora grows best in partial shade to partial sun conditions. It requires bright but indirect light as intense sunlight can damage the foliage and stunt its growth.
Temperature: The ideal temperature range for Sopubia parviflora Engl. subsp. parviflora is 20-30°C (68-86°F). It cannot withstand frost and extreme cold temperatures and should be protected during winters or grown indoors. Freezing temperatures can cause significant damage to the plant and may cause it to die.
Soil: Sopubia parviflora Engl. subsp. parviflora prefers well-draining, fertile, and loamy soil with a pH range of 5.0-6.5. The soil should be rich in organic matter and the plant must be grown in soil that is moist but not waterlogged. It may also benefit from occasional application of a balanced fertilizer.
Cultivation Methods
Sopubia parviflora Engl. subsp. parviflora can grow in various types of soil, but it thrives best in well-drained soils that are rich in organic matter. If the soil in your area is heavy, clayey, or compacted, you can amend it with compost, aged manure, or other organic materials to improve drainage and loosen the soil. The plant prefers partial shade to full sun exposure.
When planting, space the seedlings at least 30 cm apart to allow adequate air circulation and spread. Deep watering the soil a couple of hours before uprooting the plant helps prevent root damage. Water the plant immediately after planting. Mulching with organic materials such as compost, shredded leaves, pine needles, or straw helps keep the soil moist, suppresses weed growth, and regulates soil temperature.
Watering Needs
Sopubia parviflora Engl. subsp. parviflora prefers regular watering, but excessive watering can lead to root rot and other plant diseases. Watering the plant once or twice per week during the growing season and reducing watering in winter helps maintain optimal soil moisture levels. Avoid watering the leaves as it can cause fungal and bacterial diseases.
One way to check if the plant requires more water is by sticking your finger into the soil. If the soil feels dry to a depth of one inch, it's time to water the plant. Using a watering can or drip irrigation system will help deliver water uniformly and ensure efficient soil saturation. To reduce water evaporation, water the plants early in the morning or late in the evening.
Fertilization
Sopubia parviflora Engl. subsp. parviflora requires moderate fertilizer throughout the growing season to maintain optimal growth and flower production. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium is ideal. The fertilizer should contain micronutrients such as iron, zinc, and manganese for the best results.
You can apply the fertilizer once every month during the growing season. The amount of fertilizer to be applied should follow the instructions on the fertilizer package. Over-fertilization can lead to burning of the leaves and excessive vegetative growth at the expense of flower production.
Pruning
Pruning is not a crucial requirement for the Sopubia parviflora Engl. subsp. parviflora plant. However, pruning old or damaged stems and flowers helps improve the plant's appearance, promote air circulation, and increase flower production. Prune the plant immediately after flowering and remove branches or stems that interfere with the plant's growth or those that show signs of insect or disease infestation.
The best equipment for pruning is a pair of clean, sharp pruning shears. Disinfect the shears using a solution of rubbing alcohol or bleach to prevent the spread of diseases. After pruning, dispose of the pruned waste far from the plant to avoid reinfection.
Propagation of Sopubia parviflora Engl. subsp. parviflora

Propagation of Sopubia parviflora Engl. subsp. parviflora can be done through several methods, including:
Seed Propagation
Seeds of Sopubia parviflora Engl. subsp. parviflora can be obtained from mature fruits of the plant. The seeds should be sown in a well-draining soil mix. The soil should be kept moist and warm. Germination of the seeds usually takes between two to four weeks.
Cuttings Propagation
Cuttings of Sopubia parviflora Engl. subsp. parviflora can be taken from the stem tips of the plant. The cuttings should be about 4-6 inches long and free of diseases and pests. The cuttings should be dipped in rooting hormone to speed up the rooting process and then planted in a well-draining soil mix. The soil should be kept moist and warm. Rooting of the cuttings usually takes between two to four weeks.
Division Propagation
Division propagation of Sopubia parviflora Engl. subsp. parviflora is done by dividing the plant into smaller sections. This method is best done during the plant's dormant period. The sections should be planted in a well-draining soil mix and kept moist until new growth emerges.
Propagation of Sopubia parviflora Engl. subsp. parviflora is relatively easy. However, it is important to note that the plant prefers cool temperatures and does not do well in hot climates. Therefore, it is essential to provide the plant with adequate shade and moisture to ensure successful propagation.
