Merritt’s Supreme hydrangeas, like many other hydrangea varieties, prefer to be grown in part shade. They can tolerate full sun, but only if they are planted in consistently moist soils. It is important to note that these hydrangeas thrive best in rich, well-drained soils with medium moisture levels.
When it comes to soil pH, it actually affects the flower color of most cultivars of hydrangeas, including Merritt’s Supreme. However, the white variety is not affected by soil pH and will maintain its white color. In highly acidic soils, the flowers of these hydrangeas will appear blue, while in slightly acidic to alkaline soils, the flowers will range from lilac to pink.
To ensure the best growing conditions for Merritt’s Supreme hydrangeas, it is recommended to plant them in an area with partial shade. This means they should receive a few hours of direct sunlight in the morning or late afternoon, but be protected from the intense midday sun. This can be achieved by planting them under the canopy of taller trees or in a location that provides filtered sunlight.
In terms of soil, it is important to prepare the planting area properly. Start by enriching the soil with organic matter, such as compost or well-rotted manure, to improve its fertility and drainage. This will create a conducive environment for the hydrangeas to establish their roots and grow well.
When planting Merritt’s Supreme hydrangeas, dig a hole that is about twice the size of the root ball. Place the plant in the hole, making sure that the top of the root ball is level with or slightly above the soil surface. Backfill the hole with soil, firming it gently around the roots. Water the plant thoroughly after planting to help settle the soil and ensure good root-to-soil contact.
In terms of care, it is important to provide regular moisture to these hydrangeas, especially during hot and dry periods. Mulching around the base of the plants with a layer of organic mulch, such as wood chips or shredded bark, will help conserve moisture and regulate soil temperature. This will also suppress weed growth, which can compete with the hydrangeas for nutrients and water.
Pruning is another aspect of care for Merritt’s Supreme hydrangeas. They should be pruned in late winter or early spring, before new growth begins. Remove any dead or damaged wood, as well as any weak or crossing branches. This will help maintain a healthy plant and promote better air circulation, reducing the risk of disease.
Merritt’s Supreme hydrangeas prefer to be grown in part shade, but can tolerate full sun with consistently moist soils. Pay attention to the soil pH, as it will affect the flower color of most cultivars. Provide regular moisture, enrich the soil with organic matter, and practice proper pruning to ensure the health and beauty of these hydrangeas in your garden.
