As spring arrives, gardening expert Adam Kirtland emphasizes three essential tasks for April that can significantly enhance both the productivity and aesthetics of outdoor spaces. First, he advises gardeners to plant potatoes, suggesting two methods: in the ground by digging a trench or in containers like buckets. Second, garlic can be planted using cloves from supermarket bulbs, with specific instructions for spacing and depth. Additionally, April is a great time to sow fast-growing seeds such as radishes and beetroot, which can thrive even in limited spaces like windowsills. Finally, Kirtland highlights the importance of deadheading daffodils to ensure beautiful blooms next year. By removing wilted flowers, gardeners can encourage the plants to produce new blooms, leading to a longer flowering period.
