With spring underway, David Domoney has shared five jobs gardeners should focus on this week.

Jobs of the Week

1. Sow French marigolds in April for vibrant summer colour and natural pest control. Start seeds indoors or sow directly into well-drained soil after frost risk passes. Keep in a sunny spot and water regularly. Their strong scent deters whiteflies, making them ideal for companion planting in greenhouses and vegetable beds.

2. Check currants and gooseberries in spring for sawfly grubs, which strip leaves quickly. Inspect the undersides of leaves and hand-pick grubs early. Encourage predators like birds and use nematodes if needed to deter them. Regular monitoring prevents severe infestations and ensures a healthy fruit harvest.

3. Plant pond marginals in April for strong establishment. Choose plants like marsh marigold (Caltha palustris) and pickerel weed (Pontederia cordata). Position in shallow water or damp margins using aquatic baskets with loamy soil. These plants provide habitat, improve water quality, and add seasonal colour to your pond. To find out more about each of these plants, check out my plant profiles on YouTube @daviddomoney.

4. Harden off young plants in April to prepare them for outdoor conditions. Gradually introduce tender plants like tomatoes, courgettes, and dahlias to cooler temperatures over seven to 10 days. Start with a sheltered, shady spot, increasing sun and wind exposure daily. This strengthens growth, preventing transplant shock and ensuring healthier plants.

5. Sow beetroot seeds in April as the soil warms. Direct sow in well-drained, fertile soil, spacing seeds 10cm apart in rows. Thin seedlings once they appear for proper root development. Keep soil moist for even growth. Varieties like ‘Boltardy’ resist bolting, ensuring a steady summer harvest of sweet, tender roots.
