- In the winter: Maintain spaced watering, checking the humidity of the substrate.
- During the summer lethargy (summer): Leave the plant without watering unless you notice extreme dryness. The bulbs need this rest without hydration to activate the next flowering period.
If the plant is in an area with frequent rainfall, adjust the frequency to avoid overwatering.
4. Subscriber
During the growing and flowering season, it is advisable to provide additional nutrients:
- Slow release fertilizer for bulbous plants at the beginning of spring and just after flowering.
- use fertilizers low in nitrogen and rich in phosphorus and potassium to promote flowering and healthy bulbs.
- Do not fertilize newly planted bulbs or those that have not yet produced leaves, to avoid damage or root burns.
Avoid getting fertilizer on the leaves and water after application to facilitate absorption.
5. Planting: when and how to do it
El optimal time to plant bulbs It's in late summer or early autumn, about 4 weeks before the first frost. It's important to:
- Place the bulbs with the point up, An 10cm depth.
- Separate the bulbs 15-20 cm apart to allow its development.
