Detailed Guide to Lily Planting Methods and Topdressing Techniques
Planting: (1) Digging trenches: the direction of the trench should be perpendicular to the direction of the bed, with a trench depth of 5-10 cm. (2) Placing the bulbs: be careful to protect the newly grown tender roots. (3) Covering with soil: the soil cover should be slightly higher than the bed surface to help preserve moisture and drainage.
Topdressing: (1) Mainly use chemical fertilizers containing mainly nitrogen and potassium; some liquid organic fertilizers such as soybean cake water can also be used. Lilies generally do not need phosphorus fertilizer; phosphorus can be provided by organic fertilizer. (2) Fertilization timing. One month after emergence, apply soybean cake water and 0.5% ammonium sulfate; apply a mixture of 0.2% potassium nitrate plus 0.2% ammonium sulfate. After flower buds appear, foliar topdressing can be done by spraying a 0.05% potassium nitrate solution. After flowering, apply chemical fertilizer once more to promote bulb enlargement.
