Culture advices

Bidens

Description: Its bright yellow colour and slightly hanging growth makes this plant ideal for mixed (combination) planting. The strong demand for water, light and fertilizer needs to be taken into account.
Potting: 11/12 cm pots, week 6 - 10, one young plant per pot 18 - 25 cm, hanging baskets, week 3 - 8, 3 plants per basket
Substrate: Substrate of type 2 (with clay portion)
pH 5 - 6
Fertilization: Very consumptive, 1 - 2 x a week max. 1.5 g/l
Temperature: 16 - 18 °C, lower later to 12 - 14 °C
Light: Cultivate in full light, no shadow!
Flowering: From 15th week depending on light conditions (if no extra light is used).
Growth regulators: Whenever needed spray once or twice 0.05% Topflor, Caramba (0.1 - 0.2 %) or Regalis (0.25%). DIF/Cool Morning is of advantage! The ‘Yellow Wonder’ variety is naturally compact and can be cultivated in a cool environment without the application of any inhibitors.
Pinching: Lopping or shaping is recommended in order to get a better plant build-up.
1 to 2 weeks after potting or immediately in case of a suitable young plant size.
Diseases and pest: Mildew, botrytis, white fly, thrips, miner flies; take hygienic measures!
Water balance is of importance; the plants must not stand too wet, danger of botrytis, damage to roots and irregular plant build-up are the consequences.
