Indulge in garden diversity with the charming Thompson and Morgan Sweet Pea Heirloom Mixed Seeds. It offers a vibrant array of colours along with an intensely sweet fragrance. This assortment features smaller flowered heirloom types (Grandiflora) that enhance any garden with their bright hues and delightful scent. Train these plants against arches or trellises for a captivating trailing display. For best results, sow sweet pea seeds indoors in October for spring transplanting, or sow directly outdoors between March and April. In autumn, place three seeds in each 7.5cm pot at a depth of 1cm in free-draining seed sowing compost. Store in a propagator or seal in a container inside a plastic bag at a temperature of 20-25°C until germination occurs in 10 to 21 days. Once germinated, transfer the plants to cooler conditions, and later move them to a cold frame for overwintering. For spring sowing, plant seeds directly into drills at a depth of 2.5cm, spaced 7.5cm apart. To promote bushy growth, pinch out the growing tips once the second pair of leaves appears. In spring, space out your sweet peas by 23cm in any well-drained soil in full sun. Regular feeding and watering are essential throughout the growing season. To encourage continuous blooming, frequently cut flower stems, and deadhead spent blooms to prevent seed pods from forming. This variety thrives in various settings, such as patios, walls, fences, cottage gardens, and scented gardens. Sweet Pea Heirloom Mixed is a hardy plant that can grow up to 180cm tall and spread up to 30cm wide. Each packet includes 20 seeds and comes with detailed growing and care instructions.
