How to Grow
Pot up and grow sweet pea plants on in cool, bright conditions until large enough to transplant outdoors. Pinch out the growing tips of sweet pea plants while they are still small, to encourage bushy growth. When plants are well grown transplant them outdoors into any fertile, well drained garden soil in full sun or semi-shade.
More Info
Feed and water regularly throughout the growing season. When growing sweet peas it is essential to cut the flower stems frequently and deadhead faded blooms to prevent seedpods developing. This will encourage more blooms to be produced and extend the flowering period throughout summer.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
