Use a friable, coarse-fibered peren

Use a friable, coarse-fibered perennial media
containing 10-20 % clay, 0-15 % organic matter
(such as wood chips or bark humus), a multiple
balanced fertilizer at 1-1.5 kg per m³, Radigen at
100 g/m³, and a coated time release fertilizer (4-5
months) at 3-4 kg; pH value: 5.5-6.0
Temperature:
15-18 °C. Non-frost-free overwintering: Cover the
plants with a non-woven cloth to protect against
direct sunlight. Frost-free overwintering: 3-5 °C
Fertilization:
Heavy feeder. Apply 150-200 mg N per l of a
balanced multiple fertilizer containing a high
percentage of nitrate nitrogen. Ensure a good
potassium supply. Avoid overfertilization with
nitrogen. Use 1-2 applications of sequestered iron
to avoid iron deficiency.
