Sweet peas are best planted in early spring, before the soil becomes too warm. Planting at that time ensures their survival through the summer heat and also has them flowering well before you need to eat them!
How do I make sweet pea flowers last longer?
You can help your sweet peas flower for longer by burying half of each root ball deep in the soil. Plant sweet pea seeds or transplants about 1/2″ (1 cm) below the surface of garden loam and water lightly so they don’t become waterlogged. Water regularly during dry periods until plants begin to bloom.
