General Hydrangea Information and Links
Origins - Hydrangeas naturally occur in North and South America, China, Japan, Himalayas, and the Philippines. The name Hydrangea comes from Hydra meaning water, and Agos meaning a vessel referring to a cup shaped seed head.
Plant Spacing - Plant at least 1 metre apart, and better at 1.5 metres apart.
Soil Requirements - Hydrangeas like a free draining organically rich loam. The soil should be loose and friable around a newly planted plant. Avoid sand and clay.
Fertilizer - Quality topsoil is naturally slightly acidic and no fertilizer should be required. To make flowers pinker add a small amount of lime to the soil surface. To make flowers go bluer add a small amount of aluminum sulphate to the soil surface. If fertilizer is used a small amount occasionally to the soil surface is preferred to a lot at once.
Watering - Hydrangeas do not need watering once established and are mostly drought tolerant. If watering is done after planting, water only occasionally as excessive watering may cause root damage.
Wind - Hydrangeas are tolerant of windy conditions and tolerant of semi coastal environments.
Pruning - It is not essential for Hydrangeas to be pruned. When it is done pruning consists of removing old flower stems and pruning stems back to 2 buds.
Pests and Diseases - Hydrangeas might get a bit of leaf spot, especially in humid conditions. The solution if required is to spray occasionally with a mild fungicide, or wait until leaf drop in winter when most hydrangeas clean themselves.
Tub Plants and Cut Flowers - Hydrangeas can be used as a tub plant and as a cut flower. Flowers form on previous seasons stems, and pruning may reduce new seasons flowers. Flower types are mopheads, lacecaps and pannicles.
