Additionally, deadheading spent flowers and providing proper support for climbing varieties will encourage continuous flowering throughout the season.

The best time to plant sweet pea seeds varies depending on the climate and region. In cooler climates, planting the seeds in early spring as soon as the soil can be worked is recommended.

Vertical gardening not only maximizes space but also adds a vertical dimension to your garden, enhancing the overall beauty of your outdoor environment.
