Plant Gardens 101

Hydrangeas are very popular for landscaping mainly because of their dazzling display of flowers and spectacular foliage. It also is an easy to care for shrub given the correct growing environment. And a magical occurrence is that the color of hydrangea flowers can be manipulated by just changing the soil pH-dependent mobilization and uptake of soil aluminium into the plants.

Hydrangea macrophylla is a species native to Japan and Korea. However, it is widely cultivated in many parts of the world in many climates, and a must have shrub for shade and partial shade being that is so showy. In this country we refer to it as a “French Hydrangea”. In landscaping design, Hydrangea macrophylla add a splash of springtime color to shady areas and woodland gardens. Once hydrangeas become established, they can grow quite vigorously. If they do become prolific, occasional summer pruning is recommended to keep them in bounds. The flowers are easily air-dried and are long lasting making terrific indoor décor displays. (more…)

There are many species of this deciduous shrub to choose to grow in your landscape design. They have many positive aspects and are a pleasant showy splash of color in your garden. Most species of hydrangeas can be grown in either full sun or partial shade. They are resistant to most insects and diseases. They can be grown in a wide range of soil but prefer a rich, moist soil and make sure they are planted where watering will not be a problem. Their large, soft leaves lose water quickly, especially on hot, windy days, causing the foliage to wilt, so avoid dry windy sites. A list of some Hydrangea species you may want to consider follows.

Hydrangea macrophylla — Hortensia or Florist Hydrangea is a widely grown hydrangea with large globe-shaped flowers. The color of its blooms is dependent upon the pH of the soil in which it is grown: blue if acid; pink if alkaline (lime can be added to the soil to force this). There are also several white-flowered cultivars. Pruning can be accomplished at two different times: early spring and late summer (more desirable). Most hortensia types flower only from the end buds of upright or lateral shoots produced during late summer. Prune from the lower parts of the stems and crown as soon as the flowers have faded and strong shoots are developing. Pruning this species too late in the fall (after September) is harmful. Hydrangea macrophylla is a good seashore shrub; flowering is more profuse in an open, sunny location; however, hydrangeas are shade-tolerant. (more…)
