Delayed Gratification
You can also start off some seeds for flowering next year. Perennials are the gift that keeps on giving and usually pop-up year after year, however, they can take time to get started. You can sow Echinacea seeds now, in preparation for beautiful blooms next year.
Top Tips for Sowing Success in May
Once you've chosen your herbs and summer flowers — here are a few golden rules to keep in mind.
Always check the packet for specific depth and spacing guidance before you sow. Our seed packets all come with instructions. Water gently using a fine rose on your watering can to avoid disturbing seeds. Keep the soil consistently moist until seedlings emerge and establish themselves properly. Try our compostable seed labels so you can remember what you have planted where. And most importantly, enjoy the process. There is something deeply satisfying about watching a tiny seed become something beautiful. Happy sowing!
