If more chemical fertilizers or concentrated fertilizers are applied, it is easy to damage the roots. Applying base fertilizer in winter has a cold-proof effect. Top dressing before spring germination, mainly potassium fertilizer and phosphorus fertilizer, is beneficial to strong roots.

Five-leaf pine is suitable for thin application and less application, and fully decomposed bio-organic fertilizer (the source of vitality of national light) is suitable. Fertilize every three to four weeks from spring to early winter. It is hot in July and August, so it is advisable to apply 10% diluted fertilizer water every half month 1 time.

Fertilization of mature plants should be carried out in spring and autumn. Spring fertilizer is applied every 10 day 2-3 months before germination, and the concentration is about 15%, which promotes germination and long branches. It is hot in July and August, so it is suitable to apply 10% diluted fertilizer water once a month 1 time, once in the morning and once in the evening.
