What makes this variety stand out

Yellow Submarine stands out for both the shape of its fruit and the way it bears. Its pear-shaped fruits grow in long trusses, so you can harvest plenty from a single plant at once. This is an early variety – the first fruits ripen about 2 months after planting out the seedlings.

Its sweet, mild flavor, without pronounced acidity, makes Yellow Submarine an easy choice for people who don’t usually enjoy tomatoes. Fruits this size are convenient to eat whole, and combined with red and dark varieties, they make a colorful mix.

Growing step by step

Sowing (March–April, under cover): Sow seeds from mid-March to early April, about 6–8 weeks before the planned planting-out date, at a depth of about 0.5–1 cm. Keep the growing medium slightly moist and the temperature steady at 20–25°C (ideally around 24°C). Seedlings emerge after 7–10 days. Once they have emerged, seedlings need as much light as possible – on a windowsill, a south-facing window or supplemental lighting works well; otherwise, plants quickly become leggy.

Pricking out: When seedlings develop 2–4 true leaves, transplant them individually into pots 8–10 cm in diameter, planting them slightly deeper than before. Keep the seedlings in a bright place at 15–20°C and water moderately but regularly. Start hardening them off 7–10 days before planting out by placing them outdoors for a few hours each day.

Planting out (May): Plant seedlings in a greenhouse or unheated polytunnel from early May, or outdoors after May 15–20, once the risk of frost has passed. Space plants about 50 cm apart in rows, with 100 cm between rows. Bury the stem significantly deeper than it was in the pot – the tomato will develop additional roots along it. Insert a stake or attach a training string straight away.

Care: Train plants to one or two stems and regularly remove side shoots (often called suckers) growing in the leaf axils – this directs the plant’s energy into the fruit rather than leafy growth. Water at the base of the plant without wetting the leaves, as tomatoes are susceptible to late blight. Remove lower leaves so they don’t touch the soil; mulch helps retain moisture and prevents soil from splashing onto the leaves. Tomatoes prefer soil rich in organic matter and potassium, so they respond well to compost and organic fertilizers for fruiting vegetables. Long trusses laden with fruit can break, so it’s worth tying or supporting them, especially when yields are heavy.

Uses

Yellow Submarine is a tomato to enjoy fresh – straight off the vine, as a snack for children, or in a lunchbox. The pear-shaped fruits look great in salads, on skewers, and on a snack platter. They’re also suitable for pickling in jars and for quick tomato sauces.

Gardener’s tip

In a greenhouse, Yellow Submarine can grow very tall. When the plant reaches the roof, drape the top over a wire or pinch it out – fruits set higher up won’t have time to ripen before autumn anyway.
