The Royal Horticultural Society (RHS) has issued urgent advice for British gardeners, revealing it's not too late to shield outdoor spaces from the recent onslaught of snow and frost. With yellow and amber weather warnings in place and temperatures plunging below zero across the UK, the society has outlined crucial, actionable steps to prevent winter havoc.
Essential Winter-Proofing Techniques
According to the RHS, several key methods can prevent significant winter damage to gardens. Improving shelter, staking plants, mulching, and wrapping pots are highlighted as ideal for safeguarding trees, shrubs, tender plants, and even garden structures. The society emphasises that even hardy plants may need extra help to withstand these exceptionally cold conditions.
Protective wrappings, such as horticultural fleece, should ideally be applied before the first frost. If you haven't done so yet, the time to act is now. The RHS also advises gardeners to avoid using nitrogen-rich fertilisers, as these can encourage vulnerable, sappy growth that is easily damaged by the cold.
Smart Positioning and Plant Care
The specific weather conditions in your garden play a major role in how you should prepare. The RHS points out that every garden has warm and cold spots. A south-facing wall will be significantly warmer, while the colder areas are typically found on the north side of your house.
For container plants, it's vital to keep them dry and sheltered. You can group pots together for mutual protection, but remember to place bubble wrap or straw beneath them to prevent the roots from freezing. An alternative method is to dig a hole and bury the pot with only the rim visible above the soil.
Securing Structures and Managing Moisture
Winter preparation isn't just about plants. The RHS recommends checking and securing garden structures, as winter winds can loosen panels and fences. Furthermore, rain and snow can cause considerable damage.
Ensure you have appropriate drainage to prevent waterlogging. In saturated ground, trees with shallow roots can be vulnerable to being uprooted in strong winds. If snow is accumulating, gently shake it off trees and hedges to prevent branches from breaking under the weight. This is also a good time to consider pruning any vulnerable branches to make them more secure.
For vegetable patches, consider using covers to prevent nutrient leakage from exposed soil. Additionally, mulching can stop soil from becoming overly compacted and eroded, which is a common issue after periods of heavy rainfall.
