Spring

After the temperature rose, the growth of Rhododendron recovered rapidly, and gradually entered the flower bud differentiation stage and flowering stage, which required a lot of fertilizer and water. Fertilizer and water management shall be circulated in the order of "Huabao" - clean water - "Huabao" - clean water, with an interval of about 2-4 days. The interval between sunny days or high temperature is shorter, and the interval between cloudy and rainy days or low temperature is longer or no watering. After entering the seed setting period, stop the supply of fertilizer

Summer

It is generally high temperature in all parts of China in summer, and the flower is not resistant to damp and heat, so the flower will have a short dormancy in summer. At this time, it is not suitable to water more, and the basin soil should be kept slightly dry. Do not apply fertilizer when it is hot and humid, so as not to cause plant root rot

Autumn

Hualing grass, which has passed the dormancy period in summer, woke up and began to grow in autumn. At this time, it is necessary to quickly follow up the water and fertilizer management. The interval period is 1-3 days. Water can be thinly applied and liquid fertilizer can be applied frequently

Winter

Although it still continues to grow, the low temperature will slow down its growth rate, and there are few requirements for fertilizer and water. It even needs to control fertilizer and water. Fertilizer and water management shall be circulated in the order of "Huabao" - clear water - "Huabao" - clear water - clear water, with an interval of about 4 ~ 7 days. Watering time shall be arranged as far as possible when the temperature is high at noon on sunny days
