Preparation for Planting
Before you plant sweet peas, make a luxurious mixture of soil containing well- decomposed manure and large quantity of compost and fill in a plant bed of depth 2 feet. Dig a fine hole to a depth of 4 inches, take a pencil and prepare holes into which you place the seeds and depress the soil for firmness, protecting it from light. Prior to sowing the seeds, soak them in water for a day (24 hours). For speedy sprouting, nick the seeds using a nail file. Temperature is not an important criterion while soaking the seeds.
Planting
The success of growing sweet pea flowers lies in sowing them in early zone 7 or even colder; plant them in early spring or late winter when the soil is sufficiently dry for working on it . (Never wait for frost) When it is very cold, take advantage of the season and begin planting sweet peas indoors into jiffy pots or six-packs Keep the seedlings to harden for a minimum period of one week, then place them out in the garden, when the soil is workable. In case you plan to make a garden towards the end of winter (Zone 8, 9, or 10), then plant them towards the later part so as to bloom in winter end and the beginning of spring.
Placement and Watering
Sweet pea flowers flourish when you bury their roots deep in the cool and damp soil and their heads are facing the sun. In order to give shade to their roots, plant low-growing plants around them. Select a site where drainage is perfect. The best soil is alkaline soil. If you feel your soil is acidic, sprinkle a little pulverized lime on the surface.
After Bloom Care
Frequently trim the blooms and get rid of the faded sweet pea flowers immediately. Do not let the plants form seed pods, because that stops them flowering. Getting rid of the fallen flowers provides better blooms. Never plant sweet peas where many legumes grew the previous year or are growing.
