Once dahlia leaves start looking pale, it's time to give a feed. Used 'Phostrogen' (
14-10-27) liquid feed, normal strength, but could have used a balanced (e.g. 7-7-7) liquid feed. Liquids act faster because they are also taken in by leaves. Granules could be used, but 'Growmore' takes about 2 weeks to work. Pleased at how many dahlias have survived in beds over winter; haven't given any extra protection.
