Nemesia densifolia may tolerate higher temperatures, but it is crucial to keep the plant cool during hot summers. In very hot and dry climates, the plant may go dormant and resume growth when the temperatures drop in the fall or winter.
Soil Requirements
The soil requirements of Nemesia densifolia are relatively simple. It requires well-draining soil with a neutral to slightly acidic pH between 6.0 and 7.5. A potting mix with a blend of sand, perlite or vermiculite mixed with organic matter like compost is ideal for indoor growth. The plant may tolerate slightly alkaline soils but needs consistent watering to prevent soil drying.
Cultivation Methods
Nemesia densifolia Grant ex Range is a hardy and drought-resistant plant that thrives in well-draining soil. It requires full sun to partial shade to grow well. The plant can be propagated from seed or cuttings, and it is advisable to plant the seeds indoors in early spring. After germination, the seedlings should be transplanted to an outdoor location with an ideal temperature range of 60 to 70 °F. Rows should be spaced about 12 inches apart.
Watering Needs
The water needs of Nemesia densifolia Grant ex Range vary depending on the growing medium, humidity, temperature, and amount of sunshine. As a general rule, the plant should be watered deeply once or twice weekly. The frequency should be increased during periods of extreme heat or drought. Plants grown in containers or under high temperatures may require more frequent watering. It is important to avoid overwatering, which can lead to root rot and other problems.
Fertilization
Nemesia densifolia Grant ex Range prefers a well-draining soil that is rich in organic matter. To improve the soil quality, the plant can be fertilized before planting with a slow-release granular fertilizer that is high in nitrogen and phosphorous. The fertilizer should be applied according to the instructions, and it is advisable to use a nitrogen-rich liquid fertilizer during the growing season every two weeks.
Pruning
Nemesia densifolia Grant ex Range requires little pruning to maintain its shape. Regular pruning should be done to remove dead foliage and spent blooms, which encourages the growth and flowering of new buds. The plant can also benefit from pruning in fall to prevent it from becoming too leggy. Pinching back the growing tips of the plant in spring can help increase bushiness and promote more blooms.

Botrytis Blight: This fungal disease causes gray mold on the leaves and flowers of the plant. It thrives in humid conditions and can spread quickly.
To manage Botrytis blight, remove any affected parts of the plant and ensure good air circulation. Avoid overhead watering and reduce humidity around the plant. Apply a fungicide if necessary.
Root Rot: Overwatering can cause waterlogged soil and can lead to root rot. This disease can cause the plant to wilt and eventually die.
To manage root rot, ensure proper drainage and do not overwater the plant. If the plant is already affected, remove it from the soil, trim the damaged roots, and repot in fresh soil.
Pests
Aphids: These insects can cause stunted growth and deformed leaves by sucking the sap from the plant.
To manage aphids, spray the plant with a strong stream of water to knock them off. Alternatively, use insecticidal soap or neem oil to control them.
Spider mites: These are tiny arachnids that cause yellowing and browning of leaves by feeding on the plant's sap.
