Want blue hydrangeas? Here’s how .. 💙 If your pink hydrangeas are stubbornly staying pink, don’t worry colour change is possible but it depends entirely on soil chemistry. To turn Hydrangea macrophylla flowers blue, you’ll need acidic soil with a pH of 5.5 or lower. In alkaline conditions (pH above 6.5), blue flowers will often turn pink or mauve, no matter what you do. As a horticulturist, here’s what I recommend for success: 🌿 Check your soil pH first – use a soil testing kit. If your pH is too high, you’ll need to gradually acidify the soil. 🌿 Add aluminium – this is the real trick. Blue pigmentation relies on aluminium being available to the plant. In acidic soil, aluminium becomes more soluble and available to the roots. 🌿 Apply hydrangea colourant or aluminium sulphate in spring, following the manufacturer’s guidelines. Water in well. 🌿 Mulch with ericaceous compost, pine needles or leaf mould. Avoid chalky soils or adding garden lime, which will undo your hard work. 🌿 Grow in pots! Even easier! Use ericaceous compost and rainwater, and monitor the pH regularly. Not all hydrangeas can change colour so look for Hydrangea macrophylla (lacecap or mophead types) as these are the only ones responsive to pH. And remember, this process takes time. You’re adjusting soil chemistry, not flicking a switch. But with a little patience, you can enjoy the most brilliant blues by midsummer. Have you tried changing your hydrangeas’ colour before?
