Trees and bushes begin to grow again and flower in spring. It is the warmer weather and longer daylight that makes this happen. Some trees grow new leaves and then have flowers, while others have flowers before their new leaves come. Plants need water, light, warmth and soil or compost to grow. During spring they get the conditions they need to begin to grow. The showery weather gives them the water they need. The longer days mean they have more daylight and warmth from the Sun which raises the temperature of both air and soil. Spring is a time when flowers bloom and trees begin to grow and reproduce. The days grow longer and the temperature in most areas become more temperate. You can also contemplate the melting of ice and thawing of the ground.
Trees and bushes that lost their leaves over the winter begin to grow new leaves again and also flower in spring. This happens because the temperature of the air and soil starts to warm up and the hours of daylight increase as the days get longer with the coming of spring. Other trees grow new leaves first.
