A few points to remember:

It’s not just plants that are thriving, weeds are competing for space and nutrients in the soil. Weeding the garden is a must before you start planting anything. See the Top 5 Weeding Tips for Your Garden

Check the seed packet to know the proper depth to plant the seeds. To speed up the process, you can use a dibber or if you have a large area to cover the Wolf-Garten Seed Sower.  Give them a good watering

Consider a green manure crop to revive an overworked patch in the garden. We have a Guide to Green Manure to help you get going.

Fertilise! To know what the fertilise and when, check out our Guide to Fertilising in Summer
