Spring is the peak season for the growth of trumpet creeper, which grows fast and consumes more nutrients, so it is necessary to apply fertilizer in time.Usually, it is necessary to supplement fertilizer every half month in the middle, and compound fertilizer is OK.Can be directly apply near that roots of the plant, and is diluted by watering after application to promote quick absorption.In addition, its flowering period is also concentrated in spring, specifically around May.Phosphorus and potassium fertilizers should be applied before May to promote faster differentiation of flower buds, so that the color of flowers will be more bright and the flowering period will be prolonged.
Campsis itself is a plant that likes to fertilize, so it is necessary to fertilize frequently during the maintenance period.Specifically, between March and May in spring and September and October in autumn, the plants in these two periods are in the growing season, consuming more nutrients, only by supplementing fertilizer can they grow vigorously and absorb them faster.
Although Campsis grandiflora is fond of fertilizer, attention should be paid to controlling the amount and frequency of fertilization, not too much or too frequently, otherwise it will also bring fertilizer damage and easily burn roots.In normal management, once excessive fertilization is found, it should be treated as soon as possible, diluted with clean water, and in serious cases, pots and soil should be changed to re-plant, so as to avoid fertilizer damage and plant death.
