Light Requirements
Resedella dregeana Müll.Arg. requires full sun to grow and develop properly. This plant typically grows in open grasslands and rocky areas where it can receive direct sunlight for most of the day.
Temperature Requirements
This plant can tolerate a wide range of temperatures. However, it prefers a moderate climate with temperatures ranging from 15-25°C (59-77°F). Resedella dregeana Müll.Arg. is not very frost-tolerant, and extremely low temperatures can kill this plant.

Cultivation
Resedella dregeana M?ll.Arg. is a hardy plant that is easy to grow in the right conditions. It prefers well-drained soil that is sandy or loamy, with a pH range of 6-7.5. This plant is also tolerant of a wide range of temperatures, but it does best in areas with warm summers and cool winters.
When planting Resedella dregeana M?ll.Arg., make sure to choose a site that receives full to partial sunlight. It can be grown both in pots and directly in the ground, and should be planted during the fall or spring.
Watering Needs
Resedella dregeana M?ll.Arg. requires moderate watering, particularly during the growing season. In general, it's best to water the plant deeply once a week, rather than giving it small amounts of water frequently. This will encourage the plant's roots to grow deeply into the soil and become more resilient.
It's important to note that this plant is sensitive to overwatering, and its roots can rot if they are exposed to too much moisture. To ensure that you are not overwatering the plant, allow the top inch of soil to dry out before watering it again.
Fertilization
Resedella dregeana M?ll.Arg. does not require a lot of fertilization, but adding compost or well-rotted manure to the soil during the planting process can help ensure that the plant has enough nutrients to grow well.
If you choose to fertilize the plant, use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20. Apply the fertilizer once a month during the growing season, taking care not to overfertilize.
Pruning
Resedella dregeana M?ll.Arg. does not require extensive pruning, but removing any dead or damaged stems can help keep the plant healthy and looking its best.
To prune the plant, use a pair of clean, sharp shears. Cut back the stem just above a healthy leaf or bud, angling the cut at a 45-degree angle. If you need to remove more than one-third of the plant, do it gradually over several weeks to avoid stressing the plant.
Propagation of Resedella dregeana Müll.Arg.
Resedella dregeana Müll.Arg. can be propagated through various methods including seed propagation, stem cuttings, and division.
Seed Propagation
The most common method of propagation for Resedella dregeana Müll.Arg. is through seed propagation. The seeds are formed in the fruit capsules and can be collected once they turn brown. After collecting the seeds, they should be dried and stored in a cool, dry place until they are ready to be planted. The best time to plant the seeds is during the spring or summer. The seeds should be sown in well-draining soil and kept moist until they germinate.
Stem Cuttings
Resedella dregeana Müll.Arg. can also be propagated through stem cuttings. The cuttings should be taken from healthy, mature plants during the spring or summer. The cuttings should be approximately 10 cm long and should have at least two nodes. After taking the cuttings, remove the leaves from the bottom half of the stem and dip the cut end in rooting hormone. Plant the stem cuttings in well-draining soil and keep the soil moist until roots develop.
Division
Another propagation method for Resedella dregeana Müll.Arg. is division. This method involves dividing the root ball of an established plant into smaller sections. The best time to divide this plant is during the spring or fall. Gently remove the plant from its container or the ground and separate the root ball into sections using a sharp, sterile knife. Each section should have at least one shoot and a sufficient amount of roots. Plant the divided sections in well-draining soil and keep them moist until they establish new roots.

Common Pests
One common pest that may affect Resedella dregeana is spider mites. Spider mites are tiny pests that can cause yellowing and browning of leaves. To manage a spider mite infestation, wash the plant with a strong stream of water and avoid overcrowding plants. In severe cases, insecticidal soap or miticides may be used.
Another pest that may affect Resedella dregeana is thrips. Thrips are tiny insects that can cause discoloration of leaves and flowers. To manage a thrips infestation, remove any affected plant parts and avoid overcrowding plants. Insecticides may also be used, but prevention is important.
Overall, Resedella dregeana is a hardy plant that is not commonly affected by pests or diseases. However, it is still important to be aware of any potential threats and take steps to manage and prevent them.
