Nemesia – Sunsatia® Lemon
Dead-Heading Not Necessary
Self-cleaning, no deadheading necessary. Sunsatia do not like to have wet feet so be sure to plant them in places with good drainage. For most people planting them in containers will be easier than planting in the ground. However, if you do have excellent drainage in your ground beds, for instance if you use raised beds, they will also flourish in the ground.
Plants may be trimmed back with a sharp pair of scissors or pruning shears at anytime, although this is not usually necessary. Plants may flush out of flower if night temperatures begin to stay in the upper 70's or above. If this happens a light trim to shape them would be good. The trim will increase branching and will result in more flowers once the temperatures fall and the plants begin flowering again.
A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Pinching and Growth Regulators
For all sizes of containers, pinch the liner 1–2 weeks after transplant; for containers larger than 6” and for hanging baskets, trim around the edge of the container as needed prior to spacing or hanging of the baskets.
Sumagic at 5-10 ppm is effective at controlling growth if needed. Cold temperatures will also control growth.
Pest and Disease Management
General pest and disease practices as listed in notes. Sunsatia is sensitive to pythium, phytopthera, and thelaviopsis. Maintaining proper pH (5.5-5.8) and good sanitation practices will help alleviate problems. Increased air circulation, proper water management and good soil porosity are also critical. Rhapsody or copper based fungicide has been found to be effective in preventing erwinia. Agrimycin is also effective as a preventative for controlling erwinia.
Water early in the morning and maintain low humidity. Thrip control is necessary because Sunsatia is susceptible to INSV.
Grower Tips for Sunsatia
-Preventive fungicides are recommended at transplant.
