Inconsistent Weather and Chilli Plants
One of the biggest challenges of growing chillies in the UK is dealing with inconsistent weather.
Chilli plants have evolved in regions with stable climates, such as the South American rainforests or the sun-drenched Caribbean, where daily weather patterns provide consistent sunlight, a little water, and nutrients in a stable humidity environment.
The Impact of Inconsistent Weather
When weather patterns lack stability, chilli plants often show visible signs of stress. For example, during the wettest season in 100 years (2012), UK-grown chillies were significantly affected. Symptoms included:
- Smaller pods
- Slower pollination of flowers
- Reduced growth rates
- Pods with lower heat levels and less flavour
This problem is particularly noticeable in chilli varieties with less genetic diversity, such as wild and superhot types. Many of these seeds originate from plants still grown in their native climates, making them less adaptable to UK weather conditions.
Hardier Varieties for UK Climates
Some chilli varieties, like C. Annuum types (e.g., Jalapeno and Cayenne), are better suited to inconsistent weather. These varieties have been cultivated in diverse environments worldwide, allowing their genes to adapt to varying conditions. As a result, they can produce better crops even in weaker sunlight.
Adapting to a Slower Growing Season
To counteract the effects of inconsistent weather, consider limiting the pot size during slower growing seasons. Smaller pots encourage the chilli plant to focus its energy on producing flowers and pods rather than excessive foliage. This approach channels resources into what matters most—your chilli harvest.
