When sowing cucumber seeds outdoors in the UK, it’s essential to provide a warm and protected environment to ensure successful growth. The Royal Horticultural Society (RHS) advises gardeners to do one task to aid germination.
The recommended gardening task is particularly beneficial in late May when outdoor conditions can still be unpredictable, but what is the sage advice? The RHS made it clear that you must cover the sowings with cloches or fleece. The protective covering creates a warmer microclimate that promotes faster growth and reduces the risk of damage from pests such as slugs and snails.
Additionally, these covers help in retaining soil moisture, which is crucial for the healthy development of cucumber seedlings.
Leaving the cloches or fleece in place after the seeds have sprouted helps the young plants establish themselves more effectively.
This continued coverage provides a consistent environment, shielding the seedlings from fluctuating temperatures, which could otherwise stunt growth.
The RHS emphasises that this step is vital for ensuring that cucumber plants grow strongly, leading to a bountiful harvest come summer.
The benefits of using cloches or fleece extend beyond temperature regulation. These coverings also offer protection against certain pests.
By creating a barrier, gardeners can reduce the need for chemical interventions, promoting a more sustainable and eco-friendly gardening practice.
Fleece
The RHS recommends considering plastic-free fleece made from natural materials like sheep’s wool or plant-based fibres.
These options not only serve the same protective functions but also align with environmentally conscious gardening practices.
While plastic-based fleece is effective, it is often single-use and can contribute to environmental waste.
Opting for biodegradable or reusable materials helps reduce the ecological footprint of gardening activities, supporting sustainability in horticulture.
Harvesting cucumbers
May and June are the ideal months to plant the cucumber seeds into British gardens, but they will be ready to harvest between July to October.
The RHS adds: “In general, mini cucumbers should be picked at about 8cm long, small-fruited varieties at 15cm and full-sized varieties at 20-25cm.”
