Stock Double Mixed Flower Seeds are a popular variety of stocks, also known as Matthiola, that feature double blooms in a mix of different colours, including shades of pink, purple, red, and white. These plants grow up to 12-18 inches tall and produce fragrant, showy flowers that bloom in clusters from late spring to early summer. They prefer full sun and well-drained soil and are relatively low maintenance. Stocks are often grown as annuals but can sometimes be grown as short-lived perennials. They are easy to grow from seed and are often used in container gardens, borders, and as a cut flower. They are also attractive to pollinators like bees and butterflies. The double blooms of the Stock Double Mixed Flower Seeds variety offer a particularly showy and ornamental display of flowers that can add a lot of visual interest to any garden or outdoor space.
Stock seeds are sown indoors using small pots or starter trays for 6-8 weeks before the last expected frost. Press the Stock flower seeds into the soil and cover no more than 1/8 inch with soil. Stock seeds need light and continuous moisture to germinate. Transplant Stock seedlings into the garden 14 inches apart. Stock plants monthly with a general purpose liquid fertiliser. Trim the Stock flower spikes when they are down blooming. Deadheading is to neaten the appearance of the plant. Re-seeding is not a problem.
