Plant Nemesia in a spot that is sunny with full light. For the best flowers, make sure it gets a minimum of 5-6 hours of bright and direct sun every day. 

Avoid keeping the plant in the shade, as it will result in fewer or no blooms.

Grow Nemesia in well-draining, moist soil that is rich in organic content. To improve drainage, you can amend the soil using vermiculite, perlite, or sand. 

Watering

Water your gorgeous Nemesia deeply and regularly when the topsoil feels a little dry to the touch. Avoid overwatering, as excess water can cause stem and root rot. Do make sure that you are never letting the soil go dry completely.

Nemesia loves cooler temperatures and thrives best in mild summer temperatures. The best range of temperature for your Nemesia is 55-75°F or 12-23°C. This plant can thrive well as annuals in winter if you live in a frost-free place.
