Gardeners across the UK have received advice on how to care for their rhubarb plants during the current cold snap to ensure the vigour of future crops. According to gardening experts at Thomson and Morgan, it is crucial to take two simple tasks to prepare the rhubarb plants for the winter months.
Rhubarb enthusiasts are encouraged to take note that the optimal season for harvesting most varieties typically begins in late April or May, with the plants continuing to flourish throughout the summer. However, experts advise that harvesting should cease by June or be significantly reduced to avoid reducing the plant’s vigour due to over-cropping.
As the chilly weather of late October envelops the UK, dedicated gardeners are reminded to provide extra care for their rhubarb plants as they enter winter dormancy. Thomson and Morgan’s experts emphasise that rhubarb is a resilient perennial that thrives in cold conditions, producing the best crops after a cold snap.
To ensure a successful harvest of delicious crimson fruits, gardeners are recommended to use two routine gardening tools this autumn. When the rhubarb foliage starts to wither and decay, it is advised to cut back the old stalks, leaving the buds exposed, as this signifies the ideal time for pruning.
It is crucial not to delay pruning until after autumn as the plant swiftly enters its dormant state once the foliage dies back naturally. Gardeners should carefully identify the aged stalks, gently twist them at the roots, and use clean shears for a precise cut at the base. Flower stalks, known to drain energy from the plant, should be removed at the base with a sterilised knife.
Experts stress the importance of pruning during dry weather to prevent disease, as damp conditions can make the plant vulnerable. Following the trimming of leaves, a layer of well-rotted manure can be applied around the base of the plant to conserve moisture, suppress weeds, and nourish the plant for the upcoming growing season, without covering the crown to prevent rot.
Additionally, gardeners should remain vigilant against pests such as slugs and snails that are attracted to rhubarb, addressing any infestations promptly to protect the plants. If crown rot, caused by fungi or bacteria, is detected, immediate action is necessary to remove any diseased parts of the plant to potentially save it from perishing.
These expert tips aim to guide gardeners on how to best care for their rhubarb plants during the winter months, ensuring a healthy and vigorous crop for the following season. With proper attention and maintenance, gardeners can maximise the yield of their rhubarb plants and enjoy the fruits of their labour in the months to come.
