As the calendar turns to early May, gardeners should begin transitioning citrus plants from their winter shelters—such as greenhouses or conservatories—into the open air. While the increased sunlight is beneficial for growth, the move must be gradual. It is wise to keep horticultural fleece on hand throughout the month; if evening temperatures are forecasted to drop significantly, these tender plants should be covered to prevent frost damage to new shoots.

This period also serves as the optimal time for routine maintenance and pruning. Start by inspecting the trees for any branches that have become straggly, untidy, or suffered damage during the winter. Removing these sections helps maintain a compact shape and redirects the plant’s energy toward healthy, productive growth. Citrus varieties like oranges and lemons are notably resilient and respond well to even significant pruning.

Maintaining a balanced structure is key. Aim for an open centre to allow light and air to reach the canopy’s centre, which helps prevent pests and diseases. When spacing these plants outdoors, choose a sunny, sheltered spot that mimics their native Mediterranean climate. With careful attention to temperature fluctuations, citrus plants will thrive throughout the summer months, eventually producing the fragrant blossoms and vibrant fruit that make them such a rewarding addition to any collection.
