When should I plant sweet peas?
When should I plant sweet pea seeds? A very good question!
In most areas of the United Kingdom, you can sow Sweet Pea seeds anytime between early October and late April and grow plants successfully for a good display. By successional sowing, you can have Sweet Peas to enjoy outside from mid-May to late October, depending on the season and where you live in the United Kingdom.
For the enthusiast, we recommend a sowing in late October in a cold greenhouse or frame and another in early March.
