Watering Needs
Nemesia natalitia Sond. prefers to grow in moist but well-drained soil. It is essential to water the plant regularly, especially during dry spells. However, overwatering can lead to root rot and other fungi-related diseases. It is therefore crucial to ensure that the soil is not waterlogged before watering.
Fertilization
Nemesia natalitia Sond. does not require heavy feeding, but an occasional application of slow-release fertilizer in spring can help boost its growth. Avoid applying any fertilizer during the winter months or when the plant is dormant. High nitrogen fertilizers should be avoided as they can cause excess vegetative growth at the expense of flowers.
Pruning
