Sow in fertile soil that is free of weeds and rake it to a fine, crumbly consistency. Use a taut string to make a straight line and take out a shallow drill.
Sow the seeds along the drill, making sure they are 10-15cm apart. Use your hand to fill the drill with soil, lightly covering the seeds.
Water the seeds well, adding a label to the area so you know what you're growing. Keep the soil most, but not saturated, as seedlings begin to grow, and cover with a cloche.
If you're looking to grow flowers for vibrant summer colour, look no further than zinnias.
When seedlings have formed a couple of pairs of leaves, thin them to around 30cm apart. Water frequently in dry weather and keep weed-free.
