Quadrato D'Asti Rosso

Family: Solanaceae Sweet Pepper

Sun-warmed and richly aromatic, Quadrato D’Asti Rosso Bull’s Horn peppers ripen to a saturated, glossy red that feels almost lacquered in the garden.

Their thick, squared-shouldered walls are crisp and juicy, with a sweet, gently tangy flavor and a satisfying snap that holds up beautifully in bold, colorful preparations. Grow them for fresh use, roasting, and vibrant sauces—each pepper brings a distinctive, horned silhouette and a deep, sweet-red presence to the harvest basket.

Frequently Asked Questions

What’s the most common disease or pest for Capsicum annuum (Quadrato D’Asti Rosso) in home gardens, and how do I control it?

A frequent problem is aphids and thrips that weaken plants and can spread viruses, especially in warm weather. Check the undersides of leaves weekly; hose aphids off with a strong spray, then apply insecticidal soap if numbers persist. Keep leaves dry (water at the base) and remove badly affected leaves early to slow spread.

How often should I water Quadrato D’Asti Rosso while it’s actively growing (about weeks 4–10)?

During active growth, keep the top 1–2 inches of soil consistently moist but not soggy—typically about 1 inch of water per week, split into 1–2 waterings. If the soil dries deeper than that, plants may drop flowers and slow fruit set. Mulch around the plants and water at the base to maintain even moisture.

How do I tell when Quadrato D’Asti Rosso is ready to harvest?

Harvest when fruits reach full size (about 75 days from transplanting) and the skin has turned a deep red while still firm. If you lightly press the fruit and it feels hard with minimal give, it’s ready; if it starts to wrinkle or feels soft, it’s overripe. Use clean pruners and cut the fruit with a short stem to avoid bruising.
