Avantgarde Fusion

After your hydrangea has finished flowering indoors you can plant it outside if there is little chance of night frost. Clip back the dead heads by 15 cm. Plant in a nice spot in your garden where the soil is not too dry or in a very large pot on your patio or balcony.

They are not frost resistant.

Daily watering is recommended. Only the soil should be kept moist; avoid getting the flowers wet. This can cause burns if the wet flowers are exposed to the sun. A plant with 'dry feet' will have the most attractive flowers.

It is best to plant Hy-pe hydrangeas in a special potting mix for hydrangeas. Your local garden centre is sure to have this special soil mix in stock. This plant flowers abundantly, therefore good fertilisation is very important. Do this in spring and autumn. 
The blue flower is originally pink. The acidity of the soil gradually turns the plant blue. The less lime and phosphate present in the soil, the bluer the flower. Special fertilisers for hydrangea influence the colour. 
Fertilisation is not necessary during the first year. 

The ideal temperature is between 15 and 25 Celsius. 

A partially shaded sunny spot for the most attractive plant. Never plant white hydrangeas in full sun; the leaves will turn brown.
