Ancient selection Casalino tomato seeds

Origin and characteristics

The Casalino ancient selection tomato, also known as "spagnoletta", is a variety typical of the Castelli Romani area, widely grown around Rome and in the Lazio region. The fruits have a flattened, irregular shape with characteristic ruffled ridges, turning bright red at full ripeness. The flavour is sweet and delicate, ideal for traditional Lazio-style sauces and passata.

The plant

The plant is sturdy and well branched, reaching a height of 150-200 cm with good leaf coverage. The leaves are dark green, lobed and slightly hairy. The yellow flowers grow in clustered inflorescences. The fruits have a thin, smooth skin and a compact, aromatic flesh with few seeds, often showing a slight green shoulder.

Sowing and transplanting

Sow from February to March, indoors in seedbeds or in a heated greenhouse, using a soft, fertile, well-drained and moist potting soil. Scatter the seeds or sow in rows spaced 10-15 cm apart, covering with a thin layer of soil. Keep a steady temperature of 18-20°C and water regularly with lukewarm water. Transplant outdoors between April and May, once seedlings reach 10-15 cm in height with at least 4-5 true leaves.

Growing

Casalino tomatoes thrive in well-worked, fertile, well-drained soil in a sunny spot. Watering should be regular but moderate, avoiding waterlogging. As the plant grows, support it with stakes or cages, tying it gently. Harvest generally takes place from July to September, once the fruits have reached full red colour.

Useful tips

For successful growing, avoid rotating with other nightshades (potatoes, aubergines, peppers), favour a potassium-rich fertiliser over nitrogen, and regularly remove side shoots and diseased or lower leaves. Watering without wetting the foliage helps prevent many fungal diseases.

Diseases and pests

Like many tomato varieties, Casalino can be affected by alternaria, downy mildew and powdery mildew, especially in humid conditions. Common pests include aphids, tuta absoluta and spider mites. Preventive copper-based treatments and proper crop rotation help reduce the risk.

Culinary uses

Thanks to its flavourful flesh, the Casalino tomato is perfect for sauces, passata and preserves in the Lazio tradition. It is also enjoyed halved, grilled or oven-baked with garlic, parsley and extra virgin olive oil, following the classic Roman recipe.
