Do rhododendrons change colour depending on soil?

One known rhododendron variety naturally changes color throughout the season. But the researchers note that rhododendrons and similar plants that prefer acid soils (for instance, hydrangea and azaleas) can definitely display differences in color intensity, if not hue, although the researchers do not know why, exactly.

How do you keep a rhododendron blue?

To produce or maintain blue flowers on a hydrangea bush, use a fertilizer that is low in phosphorus and high in potassium. This fertilizer may be labeled as an appropriate fertilizer for azaleas, camellias and rhododendrons.

Do rhododendrons stay green in the winter?

Rhododendrons and azaleas, both from the genus Rhododendron, have long been mainstays of late spring because of their spectacular clusters of showy blooms—plus, large green leaves that often stay green through winter. They need a certain amount of chilling to develop strong flower buds.

Do rhododendrons keep their leaves all year?

Normal: While we think of rhododendrons as evergreen, they do drop leaves just as conifers periodically shed needles. Some rhododendrons hold their leaves for a season, dropping the older leaves in spring, fall or both seasons. Other varieties can hold their leaves for three or even four seasons.

Do rhododendrons lose their leaves in the winter time?

Broadleaf evergreens, such as rhododendrons, lose water through their leaves even in winter when the weather is relatively warm and sunny or during periods of high winds. When the ground is frozen, the roots aren’t able to take up enough water in the soil to make-up for what is lost through the leaves.

What is the name of a yellow rhododendron?

Rhododendron luteum, the yellow azalea or honeysuckle azalea, is a species of flowering plant in the heath family Ericaceae, native to southeastern Europe and southwest Asia. In Europe, it occurs from southern Poland and Austria south through the Balkans and east to southern Russia; and in Asia, east to the Caucasus.

How big does a yellow rhododendron get?

More compact than some of the other Rhododendrons, the Yellow gives you greater versatility. Use it as a foundation plant, border or hedge. Maturing to a height of 5 feet, and generally growing to an equal width, this shrub is easily maintained.

Why is my rhododendron yellow?

If your soil is alkaline, you’ve found one reason for rhododendron leaves turning yellow: a mineral deficiency causing chlorosis. These shrubs take up too much calcium and not enough iron in alkaline soils. Chlorosis is very likely when the yellowing is mostly between the veins of new leaves.
