Description
If you are looking to change your pink hydrangeas blue, then Hydrangea Colourant is ideal.
Hydrangeas that grow where iron or aluminium salts are present tend to change colour and produce blue flowers. Depending on the variety, pale pink hydrangeas will turn blue best with darker pink varieties turning to mauve or blue.
The best results are obtained with plants growing in acid soil, but if your soil is alkaline the proportions should be doubled.
For both potted hydrangeas and those grown outside, simply mix Hydrangea Colourant with the soil in which the root system will develop.
After establishment, dilute the Hydrangea Colourant as directed and water weekly during growth.
Always keep out of reach of children and wear protective gloves and eye protection where possible during use.

Delivery

Delivery for items fulfilled and sold by Marketplace vendors is free of charge.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
