Crop Culture Report: Begonia Gumdrops™ Series
Recommended Containers: 4”, 6” and 8” pots, Hanging Baskets and Combination Planters
Consumer Uses: Hanging Baskets, Mixed Containers and landscape/bedding use
Crop Planning from Cell Pack:
Pot Size Plants per Pot (pp) Finish Time (weeks)
4” pot (10 cm) 1pp 5 to 7
6” pot (15cm) 1pp 7 to 9
6” pot (15cm) 3pp 5 to 7
8” pot (20cm) 3pp 8 to 10
10” to 12” pot (25 – 30 cm) 3 to 4pp 9 to 11
Temperature Requirements: 65° to 72°F initially to start growth process.
60° to 65°F nights for finish.
Plant growth is very much dependant on temperatures and moisture.
Cooler temperatures will slow growth and hold blooms on plant longer.
Media and pH Requirements: Water thoroughly and let soil dry between irrigation. Grow Begonia Gumdrops®™on drier side for control of water mold diseases. If over watered at young stage, the plant is susceptible to Botrytis. 5.5 to 6.2
Fertilizer Requirements: Use a balanced feed at 100 to 150 -PPM Nitrogen with a continuous feed program. Clean water irrigation may be necessary to maintain lower salt levels for controlled growth and maximum flower production.
Pinching Requirements: are self-branching and should not require a pinch.
Growth Regulators: The best growth regulator for Begonias is monitoring watering. Excessive water stress will reduce flowering. Cycocel at 750 to 1,500 PPM will control height. .
Disease and Insect Pests: Aphids and Thrip
Pythium/Phytophthora: Drench regularly with preventative fungicides to control root disease problems. Allow soil to dry between irrigations.
Botrytis: Good air circulation and dry foliage is key to reducing the pressures of Botrytis. Extremely high light conditions and excessive drying will damage leaves during propagation opening the plant system for Botrytis.
Comments: This Begonia has large flowers on a very full plant accompanied by a rounded growth habit.
Excessive light during propagation will cause leaf cupping and dark bronzing (caused by dehydration of leaf margins).
