My hydranges are not producing any blooms (now 3 years old) what should I use for them to flower? Thans

Hi Eve, It is not necessarily the food that is missing, maybe you are trimming them at the wrong time or are pruning off the flower buds. Also if it is in too much shade it will also not flower very well. Pruning should be done early winter to a nice fat bud. A general fertiliser like Novatec or an Organic fertiliser should give them plenty of energy. Thanks the Palmers Team
