Amaranthus seeds - caudatus Fat Spike Seeds Ref: TM01406955 SowingSow February to March in pots or trays of moist seed compost and cover with a very fine sprinkling of compost or vermiculite. Keep at a constant temperature of between 20-25C (68-77F). During germination, allow the temperature to reduce at night. This will occur naturally if using a heated propagator is avoided. After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 3-15 days.GrowingWhen large enough to handle, transplant seedlings into 7.5cm (3in) pots or trays. Gradually acclimatise to outdoor conditions for 10-15 days before planting out after all risk of frost, 30cm (12in) apart. For best results, provide any ordinary, well-drained soil in full sun.Aftercare The cut flowers last well in water and can also be dried. If this is done carefully the flowers keep their colour for some time. For pot plants provide a humid atmosphere.FloweringSummercroppingPlant typeHalf-hardy Annual Price: £2.09 Quantity:
