Ideal for bedding dahlias and single-flowered varieties (like the Bishop series) or for growing on a budget. These will flower in their first year.
1 Sow Seeds Indoors
Fill a seed tray with moist seed compost. Sow seeds thinly on the surface and cover with a fine sprinkling of vermiculite or compost about deep. Keep at in a propagator or on a warm windowsill.
2 Prick Out
When the seedlings are large enough to handle (usually having one pair of true leaves), transplant them individually into pots or cell trays to grow on.
3 Pot On
As the plants fill their small pots and roots appear at the base, move them into slightly larger containers if the weather is still too cold for planting out.
4 Harden Off
Slowly acclimatise your young plants to outdoor temperatures. Place them outside during the day and bring them in at night for a week before planting out.
5 Plant Out
After the risk of frost has passed in Newcastle, plant your seedlings into beds or containers. Space bedding varieties about apart, or larger varieties apart.

Cucumber
Cucumbers are fast-growing annual vines that produce crisp, refreshing fruits and thrive in warm conditions. They come in indoor (greenhouse) varieties and hardier outdoor (ridge) varieties. Greenhouse cucumbers are usually all-female and grown under cover for seedless, tender fruits, while outdoor cucumbers are rough-skinned ridge types that grow in open ground and require pollination. All cucumbers need full sun, rich soil, and consistent moisture for a prolific summer harvest.
Garlic
Garlic is a hardy, sun-loving bulbous vegetable from the onion family, grown for its pungent cloves used in cooking. It’s easy to grow in a warm, well-drained spot and needs minimal fuss – plant individual cloves and they will develop into full bulbs by the following summer. Most garlic varieties require a cold spell over winter to form good bulbs, so in the UK they are generally planted in autumn. There are two main types of garlic: hardneck and softneck. Hardneck types produce flower stalks (scapes) which should be removed, and their bulbs have fewer but larger cloves (they store for around 4–6 months). Softneck types have more, smaller cloves and rarely bolt; they also store for longer, often up to a year.
Basil
Basil is a fragrant, tender herb whose leaves are a staple of summer cooking. Native to tropical regions, basil is treated as an annual in temperate climates like the UK because it cannot tolerate frost. It thrives in warm, sunny conditions and can be grown in garden beds or pots for a steady supply of fresh, flavourful leaves throughout the summer.
