Tip for Growing Summer Flowers
To ensure your summer flowers thrive, first choose heat-hardy varieties that are suitable for your local climate. Most summer flowers prefer plenty of sunlight and well-drained soil, so make sure your planting site gets plenty of sunlight. Watering in the early morning prevents water evaporation and prevents water from pooling on the leaves, reducing the risk of disease. Mulching helps retain soil moisture and protects the roots from heat damage. Fertilize your plants every few weeks with a small amount of fertilizer to promote continued, vigorous blooms. Follow these simple tips for a healthy and colorful summer garden.
