It's not too late to plant Sweet Peas - Tips for the novice sweet pea grower
We spend quite a bit of time trying to select fabulous independent retailers to add to our boutiques, which involves many trips to fairs and shows around the country (shame). Quite often we get diverted (very often in fact), usually by a stall holder who draws us in with their enormous enthusiasm for their product. One such was Delma, who we met recently at the Sudeley Castle fair. Delma seems to know everything there is to know about matters horticultural and is an expert on sweet pea growing.
She kindly (and firmly) talked us through the process of soaking seeds for 24 hours, before removing them, pricking the skin gently with a needle and then re soaking for 10 minutes. Gently push the seed into good compost and place on a window sill.....all this so that the fledgling sweet pea can concentrate all its energies on pushing through the shell and realising its full, and glorious potential. Delma completely entranced us with her wealth of knowledge about the history of sweet peas, and we left with arms laden with seed packets and our clear instructions.....watch this space for progress reports. We are secretly competing with each other (some sabotage may occur).
