Hydrangeas are widely regarded as one of the most stunning and abundant flowers that you can grow in your garden.
However, they can be swiftly and unexpectedly damaged by the frost and cold weather the UK has experienced this winter.
Fortunately, there are several measures that gardeners can implement to help restore their hydrangeas to their previous splendour when spring arrives.
When the days begin to get longer, you will notice signs of life. You should see buds that soon will open into leaves and flowers.
Gene Caballero, a gardening expert and co-founder of GreenPal, shared that ensuring “hydrangeas bloom beautifully after winter” involves a few crucial steps.
1. Mulch hydrangeas
Shield your hydrangeas by mulching around the base to “insulate the roots from harsh winter temperatures”.
Remove the top inch of compost and replace it with mulch to provide a layer of protection during the winter season.
This not only aids in insulating the plant but also safeguards the soil and its nutrients from the inevitable heavy rainfall.
This in turn helps to prevent the hydrangeas from drying out and becoming stressed.
2. Prune
Pruning is an excellent method to encourage many plants to bloom, however, if done at the wrong time, it can have disastrous consequences.
Gene advised: “Avoid pruning in late fall or winter, as you may accidentally remove the buds set for next year’s blooms.
“If you must prune, do it right after they bloom in summer to avoid cutting off future flowers.”
3. Fertilse
When it comes to fertiliser, hydrangeas don’t need it during the winter months, but come early spring, they can thrive with a bit of feeding.
The gardening expert recommended: “In early spring, apply a slow-release fertiliser designed for flowering shrubs to encourage vibrant blooms.”
For most hydrangeas, a slow-release, granular fertiliser with an N-P-K ratio of 10-10-10 is perfect.
This balanced mix of nitrogen, phosphorus, and potassium will help maintain robust growth and promote flowering.
