Crop Culture Report: Angelonia Actors® Series
Angelonia is a genus of almost 30 species native to South America. The species Angustifolia or hybrids have become a large percentage of any spring production over the past
15 years. This is particularly true in the warmer regions. Angelonia’s attributes are recognized in containers, window boxes or as a performing component in the landscape with its striking colors,
height and drought & heat tolerance.
The increase in popularity came about initially with virus indexing of the original vegetative varieties creating a more uniform and crop. Breeders have taken over from that point developing many new varieties, including a series from seed, but cutting varieties like the Actors® offer more vigorous plant habits over seed lines.
Crop planning from cell packs:
Pot size: Plants per pot (pp) Crop Time (weeks)
6” pot(15cm) 1 ppp 7 to 9 weeks
8” pot (20cm) 3 ppp 7 to 9 weeks
10” to 14” pot (25 to 36cm) 3 to 4 ppp 8 to 11 weeks
Temperature Requirement: 62° to 65° F (17° to 18° C) night temperatures with a minimum of 60° F (16° C) days. Allowing the day temperature to reach 75°to 85° F (24° to 29° C) is no problem. Angelonia thrive in warm temperature conditions. Cool temperatures will slow growth and may cause yellowing of foliage.
Media and pH Requirement: Water thoroughly and let soil dry between irrigations. Do not keep consistently wet or root rot problems may develop. The first signal of consistent wet conditions could be yellowing of foliage and weak growth. The pH of the soil should be maintained at 5.5 to 6.2.
Fertilizer Requirements: Feed with a balanced feed at 150 to 250-PPM Nitrogen. In a soil-less mix, additional iron may be required. EC of 1.0 to 1.6 is optimum.
Pinching Requirement: Soft pinch once the plant is established after transplant but before the stem becomes tough. For larger containers, an additional pinch is recommended.
Growth Regulators: Items used and rates will vary greatly with growing conditions. Cycocel/B-9 ä tank mix, Sumagicä and Topflorä – Trial rates of the above chemicals for your use. High light will control the height much more effectively than any chemical.
Disease and Insect Pests: Aphids, Mites and Thrip
Pythium/Phytophthora and Rhizoctonia: Drench regularly with preventative fungicides to control root / stem disease issues.
Allow soil to dry between irrigations and good air circulation allowing foliage to dry before sunset are good cultural practices as well.
Botrytis, Pythium and Phytophthora are of primary concern. Secondary concerns are Thielaviopsis and Rhizoctonia. Regular preventative drenches /sprays are recommended to control diseases.
