Cultivation methods
Lindernia suffruticosa Lisowski & Mielcarek is a perennial herbaceous plant that is ideal for cultivation in tropical and subtropical regions. It thrives in well-drained, moist, and fertile soil with a pH between 6 and 7.5. The plant needs to be grown in full sun to partial shade.
The planting process involves digging a hole slightly larger than the root ball of the plant and filling it with soil mixed with compost or organic matter. The plant should be watered immediately after planting to help establish its roots. Mulching the area around the plant will help the soil retain moisture and suppress weeds.
Watering needs
Lindernia suffruticosa Lisowski & Mielcarek requires regular watering to keep its soil moist but not waterlogged. Overwatering can lead to root rot, while under-watering may cause the plant to wilt.
