How To Grow Sweet Peas

How To Grow Menu | Sweet Pea Varieties

When to Plant

Sow outdoors as soon as the ground can be worked.

Soak seed for 24 hours prior to planting.


Plants do best in rich, well drained soil in full sun.

Planting & Growing Information

Sow seeds 13 mm (1/2″) deep and 5 cm (2″) apart. Space plants 10 cm (4”) apart and rows spaced 10 cm (4”) apart.

Seeds germinate in 10-14 days.


Water regularly – sweet peas do best when they have cool, moist roots.

Pick sweet peas for a beautiful bouquet when the buds at the tip of the flower clusters are not yet open.

An application of garden inoculant at the time of planting will result in larger plants that grow quickly and display more flowers.

Sweet peas are heavy feeders and benefit from regular fertilizing throughout the season.

Plants require a support to climb.

Picking for bouquets, removing faded blooms and seedpods will have plants continually producing beautiful flowers all season long.

Garden Inoculant

It is a fine powder applied to the seeds at time of planting. Inoculant is living bacteria that enables garden bean and pea plants to produce nitrogen fixing nodules along the roots which act to gather nitrogen (which is vital for plant growth) from the air and soil resulting in better growth and production. In addition, the nitrogen gathered stays in the soil at the end of the season for the next season’s crops to profit from.

NOTE: Store it in a cool place.   It is best to use inoculant in the year it was purchased. Excess inoculant can be worked into the soil.
