Every garden should have Sweet Peas somewhere, they are lovely to look at, smell amazing, last a long time if they are dead headed and, when you’re ready, will provide seeds for next season.
I have grown Sweet Peas often over the years with mixed success. The best results that I can remember were from seeds bought from Alan Romans, chitted and started off at home then planted around an obelisk at the allotment. This year I have bought seeds from Seekay and from Higgledy so it will be interesting to see which seeds perform best. Both are Mammoth Mixed. The Seekay seeds were delivered quickly but the Higgledy haven’t arrived yet. My plan is to grow some at home in the garden and some at the allotment.
Today, Saturday 14th January 2017, I am swishing ten seeds in a little warm water to soften the outer shell. I shall sow them tomorrow or Monday. Five each to a small pot of compost, It’s a start. Update:- It’s been a rainy grey Sunday but the ten Sweet Pea seeds are in their pots and ten more are soaking. Another ten seeds went into the compost today, Monday 16th January. update 20th January The first pot sown 15th Jan are pushing through today. 5 days to germinate as promised by Seekay seeds.
Growing sweet peas couldn’t be easier. You can sow them into small pots of compost in Autumn and overwinter the young plants in a cold frame or cool greenhouse. Alternatively you can wait until Spring and start planting your sweet peas in pots, or sow directly into the ground.
Before you sow them soak in tepid water to rehydrate them. It helps them get off to a quicker start but it isn’t essential as they will still germinate well in moist compost. If you soak them overnight you will notice that they swell up and turn a lovely chestnut colour. Use a good quality compost and sow several sweet pea seeds to a pot. Sow them about 1cm deep, cover the seed with compost and water them well. If sowing Sweet Pea seed seems like too much effort you could always buy sweet pea plug plants. Place them in a bright position and when the shoots appear keep an eye out for slugs as they love young sweet pea shoots. Information from Sue Sanderson at T&M.
