Peter’s top sweet pea tips
1 Sweet peas are self-pollinating and come true from home saved seed. It is therefore worth collecting seed pods from good named cultivars at the end of their season.
2 Sweet pea seeds will hold germination over several years, but unlike most other seeds are better stored in paper packets rather than dry airtight tins or for longer periods in the deep freeze.
3 Autumn sown sweet peas will produce seedlings that will withstand really hard frost. Cloche or cold frame cover is advisable however to protect from excessive wet and bruising winds.
