Why Are My Hydrangea Leaves Curling?

This curling could be due to a number of reasons. The easiest ones are:

1. Check under the leaves for aphids. If you see them, there are many solutions sold in the shops to get rid of them without damaging the plant - usually a soap-type solution. To know what you are looking for, aphids are small, pear-shaped green or black bugs that feed on the leaves of many plants in late spring.

2. Is the plant in the sun? Hydrangeas do not do too well in full sunlight, so it could just be a case of moving them to a shadier spot in the garden.

3. Lack of water. These guys love their water, so check that you are watering them regularly and even more so; if they are being kept in direct sunlight.

4. The soil the hydrangea is planted in might not contain enough potassium - so a tomato feed mixed into the soil should boost the nutrients it is taking in. However, tomato feed can be expensive, so I recommend shopping around, comfrey and nettle are a bit smelly but they do the job and are cheaper!

5. Make sure you check which leaves are curling, if it’s the baby ones, look for spider mites - maybe use a magnifying glass as these insects are tiny, and if they’re laying eggs they’ll be even tinier. The females can lay 200 eggs at a time that hatch 7 days later - so you may need to invest in an insecticide or horticultural oil. If you don’t have these to hand or know what they are, no worries, just head down to your local gardening centre and they’ll be able to point you in the right direction.

If the insecticide is too expensive, you can actually make your own at home!
