Rhododendrons are acid loving plants that prefer well- . They’re members of the heather family also called lime or plants -hating plants. Lime in the soil kills the crops and usually turns the leaves of Rhododendrons yellow. Rhododendrons so are known because of their clusters of flowers that were huge and are characterised as trees or shrubs. Rhododendrons will help foundations, and serve as decorative plants in landscapes. Rhododendrons have shallow root structures which make them incompatible with a few plants. Select crops with similar needs when planting companion plants for rhododendrons.

Hydrangeas

Hydrangeas grow in moist, shaded places away in the wind and do well in soil that is acidic. Hydrangeas that do best in hotter climates, like U.S. Department of Agriculture hardiness zones 9a, 9b, 10a and 10b, contain mophead and lacecap hydrangeas (Hydrangea macrophylla) and oakleaf hydrangeas (Hydrangea quercifolia). Hydrangeas generate huge balls of outstanding blooms. The blooms are blue when developed as companions for rhododendrons in soil, however they turn pink if developed in soil. Hydrangeas developed with rhododendrons might be white or blue; they show a cluster of bigger blooms surrounding a heart of tiny, lace-like flowers. Oakleaf hydrangeas are more tolerant of sunlight than mophead and lacecap hydrangeas. Their blossoms are usually white, but the leaves of the grown in areas that are sunny with afternoon shade change shades of yellow, orange, red and purple .

Astilbe

Astilbes, fernlike plants with mounds of foliage, develop 12 to 18-inches tall and generate 2 to 3-foot-tall flower blooms that last weeks. Astilbe is hardy to USDA hardiness zone 4 and cool as -2 5 degrees Fahrenheit. They grow best in moist -shaded soil, making them especially suitable for cool, foggy locations that are developing. Although astilbe is tolerant of sunlight, the more they’re shaded are intensified by the colour of the blooms. Fertilize the soil each spring using a phosphorous method that is large as the crops multiply quickly, exhausting the soil. Divide clumps of astilbe in the spring as these crops multiply they become over-crowded or fall following several years of flowering and generate flowers.

Japanese Pieris

Pieris japonica, pieris, is generally described as Andromeda or lily-of-the-valley shrub. Using their fingerlike, flowers that are drooping, they offer an intriguing contrast. They’re indigenous to Japan, but are hardy in USDA hardiness zones 9 and 10, especially over the coast. They favor moist, properly- drained s Oil full of organic material like peat. In the event the s Oil is moist Andromeda does best-in partial shade, but is tolerant of sunlight. They grow to 6 to 10-feet extensive and heights of 1-0 to 12-feet. They grow in a form that is obviously rounded, in order that they do not need pruning except to eliminate ruined or dead foliage. Plant in clusters having accent or a rhododendron hedge rhododendrons using just one pieris plant.

Viburnum

A shrub zones 2 to 9, Viburnum, is generally utilized as a screen planting and-or for casual hedges. Viburnum is adaptable to the majority of soil conditions provided that the oil h-AS enough drainage. These crops can tolerate mild shade and grow nicely in full-sun. You would possibly use viburnum to supply extra shade to get a neighboring rhododendron.Various species of viburnum make ideal companions for rhododendrons, like fragrant snow ball, Withe rod and black haw. Fragrant snow ball crops increase 6 to 8-feet tall and create 4- to 5inch white, ball shaped flower clusters having a sweet fragrance. Withe rod develop 5 to 6 feet tall with 3- to 5 inch clusters of white, fertile flowers in early summer and vivid red leaves in drop. Haw crops increase 10 to 1 5 feet tall and create 2- to 5inch clusters of white flowers in mid-spring. Black haw creates 1/2inch blackberries that ripen in drop and they can be used by you in jams and jellies.
