Hydrangea is one of the most popular summer garden plants! They are very much beloved for their big, beautiful blooms that come in many pretty colours, such as pink, purple, blue and white. These beauties will add colour, beauty and texture to the landscape. They can be grown in garden beds or in containers. Plus, they make wonderful cut flowers and are a favourite with summer brides!
Here are some tips to make the most out of your hydrangea plants:
- Hydrangeas, especially the blue and white varieties, prefer morning sun and afternoon shade. In order words, they do best in the shade than full sun.
- Be sure to give hydrangeas sufficient space to grow. Plant in a spot where hydrangeas are able to spread at least 4 feet wide.
- Do not plant hydrangeas under trees, as tree roots are aggressive and will compete for the same nutrients in the soil and the hydrangeas may not bloom.
- Hydrangeas can be planted early summer or late fall. Plant in fertile, well-drained soil. Loamy soil is best. Adding compost can help amend your soil, if it’s in poor condition.
- Adding a layer of mulch will help the soil retain its nutrients and water content.
- Hydrangeas need to be watered regularly, as they are water-loving plants. The best time to water them is early in the morning or late in the evening and always water at the base of the plant.
- Fertilizing can increase the growth and quantity of flowers produced. The best time to fertilize is the spring. But be careful not to over fertilize, as this could lead a plant with dense foliage and few flowers.
- Pruning older plants will help encourage new growth; thin them out by cutting some of the older stems.
- Hydrangeas are known for their colour changing habits. For blue flowers, add aluminum sulfate to increase the acidity in the soil. For pink or red flowers, the soil needs to be alkaline; add lime to decrease the acidity of the soil. White flowers will remain white, regardless of soil pH. Try to use rainwater to water hydrangeas, as hard tap water can affect the soil’s pH, thus changing the colours of your hydrangeas.
