Use a well-drained, growing substrate with 15-30 % clay, 0-20 % parts (e.g. coconut fibres, perlite), 1-1,5 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3 months), iron-chelate, micronutrients, pH: 5.5-5.8. Field: well-drained, sandy loamy soils. Standard fertilization: 60-80 g/m² of a slow release fertilizer.
Grow at 20-24 °C during daytime and at 15 °C during night or outdoors. Avoid temperatures below 10 °C. Protect the young plants outdoors against frost. Gomphrena does not tolerate frost.
Moderate-high fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Take care of the phosphate level in substrate.
