March heralds the true beginning of the gardening season, a time of renewed growth and vibrant activity. As the days lengthen and temperatures gradually rise, it’s crucial to seize the opportunity to prepare your garden for the months ahead. This month offers a window of opportunity to tackle essential tasks that will lay the groundwork for a flourishing garden.
From sowing seeds to tackling weeds, March demands a proactive approach. Here's a guide to the key garden jobs that will ensure your outdoor space thrives.
March is prime time for sowing a variety of seeds. Begin with hardy annuals and vegetables under cover, such as tomatoes, peppers, and brassicas. Consider direct sowing hardy varieties like peas, broad beans, and carrots as the soil begins to warm. Planning your seed sowing now will ensure a continuous harvest throughout the summer.
Take advantage of the drier spells to tackle emerging weeds. Thorough weeding now will prevent them from competing with your plants for nutrients and water later in the season. Simultaneously, prepare your soil by forking over beds and borders, incorporating compost or well-rotted manure to improve soil structure and fertility.
March is an ideal month for pruning certain shrubs and roses. Prune winter-flowering shrubs after they have finished blooming. Cut back summer-flowering clematis and prune established roses, removing dead, diseased, or crossing stems. Inspect fences, trellises, and supports for any damage and make necessary repairs before plants start to put on significant growth.
As the soil warms, you can begin planting bare-root shrubs, trees, and hedging. Divide established perennials to rejuvenate them and create new plants. Plant summer-flowering bulbs like lilies and gladioli. If you started seeds indoors, begin hardening off seedlings by gradually exposing them to outdoor conditions.
Give your lawn its first cut of the season on a high setting. Rake out any dead thatch and aerate compacted areas. Apply a spring lawn feed to encourage healthy growth and address any moss issues.
Keep a watchful eye out for early signs of pests and diseases. Inspect plants for aphids, slugs, and snails, and take appropriate action. Apply preventative measures where necessary, such as using organic slug pellets or introducing beneficial insects.
Clear away any remaining winter debris, such as fallen leaves and broken branches. Clean and sharpen garden tools, and organise your shed. Check irrigation systems and ensure they are functioning correctly.
By addressing these key garden jobs in March, you’ll set the stage for a productive and visually appealing garden throughout the growing season.
