With the arrival of summer, gardening specialists from GardeningExpress.co.uk recommend seven low-maintenance plants that flourish with minimal care, perfect for those with busy lifestyles. Lavender is a top choice, thriving in sunny, well-drained soil and requiring little water. Cosmos are annuals that produce delicate flowers throughout the summer, thriving in poor soil with little feeding. Marigolds are robust, sun-loving plants that bloom for months without deadheading and also help repel pests. For shaded areas, ferns require minimal upkeep and thrive in moist conditions. Thyme and rosemary are hardy herbs that flourish in dry, sunny environments, making them ideal for rock gardens and culinary use. Finally, petunias are resilient in containers and hanging baskets, providing bright blooms even with occasional missed watering.
