It’s throughout this post-bloom interval that the leaves are actively processing daylight into vitality via photosynthesis, with the bulbs rising bigger as they convert vitality into sugars to retailer as meals.
Throughout this “inexperienced plant” section, potted specimens ought to be fed repeatedly each two or three weeks with a liquid or water soluble fertilizer.
Water calmly to moisten the soil earlier than feeding, then use a half-strength software of a light, balanced fertilizer similar to 5-5-5, or a flower boosting combine just like 5-10-10.
