Pots and combination planters

Celosia plumosa Sowing method

1 seed per plug, sowing directly into final pots is recommended.

Celosia plumosa Germination

7-14 days at 72-77 °F (22-25°C). Light is required for germination. Sow in a well-drained media that has good water holding capacity. Maintain relative humidity levels of 90-95 %. Cover seed lightly with vermiculite after sowing.

Celosia plumosa Growing on

Grow on at 60-65 °F (16-18 °C). Low temperatures can cause premature flowering and poor garden performance. Fertilize weekly at 150-200 ppm nitrogen in a well-balanced fertilizer.

Media

Use a well-drained, growing substrate with 15-30 % clay, 1,5-2 kg/m³ complete balanced fertilizer, iron-chelate, micronutrients, pH 5.5-6.0.

Celosia plumosa Temperature

Grow at 18-20 °C. At the end of the cultivation time decrease the temperature to 16 °C. Avoid temperatures below 16 °C, because Celosia needs warm temperatures to grow.

Fertilization

Celosia plumosa Moderate fertilization levels are required. Fertilize the crop weekly with 150-200 ppm nitrogen, using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Prevent magnesium deficiency by applying magnesium sulphate (0,025 %) 1-2 times and in case of iron deficiency apply iron-chelate for 1-2 times.
