Start sowing colourful annuals as soon as the weather warms up and the soil temperature is also a little warmer, but if you can’t wait, some can be sown undercover. A few hardy annuals prefer to be sown directly in the soil where they are to grow. Either way, annuals make a great addition to any garden with so many varieties to choose from, an array of colours and many that are great for cutting to put into a vase. Here are some of our favourites to sow and grow, including a few sowing tips.
