How much to put in a container as a potting mix please ?

When planting, apply 50g (one capful) per square metre and mix into soil. Every 7 days during growing season, dissolve 50g in 5 litres of water and apply to the soil around the shrub, avoiding the leaves and foliage

does this work in a border, or only works for containers?

it works on both, hydrangeas in pots and in the ground

I have just bought a beautiful blue hydrangea so will this product keep it blue?

Use hydrangea vitax - it keeps the blue colour in your plant all summer. If I don’t it fades, but is still a beautiful colour in the Autumn.

Is it too late in the season to use? Mine are just starting to bud...

No it's not too late, in fact this is the best time to use when the flower buds are just starting to develop.i have just used it on my hydrangeas
