It can be grown in containers or directly in the ground. If grown in containers, it is important to choose a pot with adequate drainage holes and use a well-draining soil mix to prevent waterlogging. If grown in the ground, it is beneficial to incorporate organic matter into the soil to improve its overall quality.
Watering Needs
Heliophila maximilianii Schltr. var. agtertuinensis O.E.Schulz requires regular watering, especially during hot and dry weather. It is important not to overwater this plant as it can lead to root rot. Generally, it is recommended to allow the top inch of soil to dry out before watering. It is also important to water at the base of the plant to avoid wetting the foliage, which can increase the risk of fungal diseases.
Fertilization
Fertilization is not essential for Heliophila maximilianii Schltr. var. agtertuinensis O.E.Schulz, but it can lead to healthier and more vigorous growth.

Propagation of Heliophila Maximilianii Schltr. var. Agtertuinensis O.E.Schulz
Heliophila Maximilianii Schltr. var. Agtertuinensis O.E.Schulz can be propagated via both seeds and cuttings.
Seed Propagation
To propagate via seeds, it is best to sow them in spring or autumn. The seeds need to be planted in well-drained soil in a sunny location. Before planting, soak the seeds in water for one day to loosen the hard outer covering. Once planted, keep the soil moist but not waterlogged. The seeds germinate within two to three weeks.
Cutting Propagation
Another way to propagate Heliophila Maximilianii Schltr. var. Agtertuinensis O.E.Schulz is through stem cuttings. Take cuttings in early spring or during the plant's active growth period. Cuttings should be around 4-6 inches in length. Remove the leaves from the lower half of the stem and dip it in rooting hormone. Plant the cutting in a well-drained soil mix and keep it moist. Within 4-6 weeks, roots will form, and the plant can be transplanted to its permanent location.

Agtertuinensis O.E.Schulz may include wilting, yellowing of leaves, and eventual plant death. Prompt removal of infected plants, reducing humidity, enhancing air circulation, and good sanitation are useful measures in preventing the spread of bacterial infections.
Pests
1. Aphids:
Aphids are tiny insects that feed on the sap of the stem and leaves of the Heliophila Maximilianii Schltr. var. Agtertuinensis O.E.Schulz plant. They are generally easy to control by using insecticidal soap or a strong stream of water to wash them off the plant. Use horticultural oil sprays for severe infestations.
2. Spider mites:
Spider mites are tiny arachnids that weave webs on the plant foliage and suck the sap, making leaves to turn yellow and eventually lead to plant death. A regular strong blast of water may also help manage them. Pesticides like Neem oil and insecticides containing pyrethrins can also be used for more extensive infestations.
3. Caterpillars:
Caterpillars are larvae of moths or butterflies that feed on the leaves of the plant. Prompt removal by handpicking may help in case the infestation is small. In cases of extensive damage causing defoliation, pesticides are recommended. Use Bacillus thuringiensis (Bt) insecticide for effective control.
By incorporating the right cultural practices and taking steps to protect the plants from diseases and pests, gardeners can look forward to a healthy harvest of the beautiful Heliophila Maximilianii Schltr. var. Agtertuinensis O.E.Schulz plants.
