Osteospermum – Bright Lights™ Yellow
Dead-Heading Not Necessary
Deadheading not necessary for continuous bloom. Plants will "bury their dead" (new flowers will quickly cover old flowers) so no deadheading necessary. Bright Lights Osteospermum do not like having wet feet and will react badly to constantly wet soil. Be sure to allow soil in containers to get dry on top before watering and only plant Bright Lights in ground beds with good drainage. While it shouldn't be necessary you can trim your plants with a sharp pair of scissors or pruning shears at any time.
A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
Needs Good Drainage
Bright Lights are great in both landscapes and containers.

Pinching and Growth Regulators
Pinch at transplant, if needed. If plants are pinched use a preventative fungicide spray to preclude disease formation. Florel at 500 ppm can be used instead of pinching. 5-10 ppm Sumagic can be used to control growth if needed. Cold temperatures can also be used for growth regulation.
Pest and Disease Management
General pest and disease practices as listed in notes. Symphony is sensitive to pythium, phytopthera, and botrytis. Maintaining proper pH, (5.8-6.2) and good sanitation practices will help alleviate problems. Increased air circulation, proper water management and good soil porosity are also critical.
Grower Tips for Symphony
-Low humidity isessential best in production.
-Preventive fungicides are recommended at transplant.
-Requires high light in production.
-Grow cool with good air circulation once established.
-Finishing outside will yield a toned and better branched plant.
Air circulation and water management are critical. Vernalization is not required for flowering. Removing buds and flowers at transplant is not necessary but may be beneficial.
