Sweet peas are undeniably gorgeous, but if you don’t plant them in fall, you may never get to enjoy their beautiful blooms.
If you plant your seeds in fall, you’ll start to see sweet blooms like these by mid to late spring.
Soak your sweet pea seeds to see if they swell. If any seeds stay shrunken, you need to rough up the seed coats with your fingernail or even a nail file.
Starting your sweet peas in an unheated greenhouse or garage is a great way to get an even bigger jump on the season. Once seedlings reach 2 to 3 inches tall like these starts, you can transplant them out into the garden.
The more you pick, the more your sweet peas will flower. If the stems begin to shorten and the blooms aren’t as prolific, give your sweet peas a side dressing of blood-meal soil amendment. This will prompt the plants to put on a few more weeks of the flower show.
