Sweet peas are happiest with their heads in the sun and their roots deep in cool, moist soil. When possible, plant low-growing annuals in front of them to shade their roots.

How often should you water sweet pea flowers?
Sweet peas rarely need watering more than once a week, but you need to maintain even moisture throughout the growing season. They do not like hot weather, so water them regularly in the summer, but do it early in the day to prevent buds from dropping, yielding and fewer flowers, and to prevent plants from scorching.

There are long-day, day-neutral, and short-day types. As the name implies, long-day sweet peas start producing flower buds when the days are longer than nights, and bloom between spring and summer, which is why they are often referred to as spring- or summer-flowering sweet peas.

How do you protect peas from heat?
In hot weather, heat-sensitive crops want protection from both heat and sun. Shade netting helps these plants in several ways. Most importantly, it keeps soil and air temperatures as much as 10 degrees cooler (lettuce seeds germinate poorly in soil temperature higher than 70 degrees).
