Environmental requirements, substrate, fertilizations and special precautions

Temperature: require protection from winter cold.
Light: sunny exposure.
Watering and environmental humidity: water regularly.
Substrate: all garden soils are better, better than medium-textured, rich in organic matter and without stagnation of humidity.
Special fertilizations and tricks: if grown in pots, 12-14 cm containers must be used. in diameter for each plant, or 25 cm. in diameter for a group of three plants.


Normally snapdragons reproduce by seed, in February-March, in a warm bed, in bowls filled with a mixture of peat and sand in equal parts. The seeds placed on the substrate must be slightly wet with a watering can with thin holes and, subsequently, covered with a thin layer of sand. Germination usually takes 8-12 days. The new seedlings will have to be repackaged in 8 cm pots. in diameter and, subsequently, in larger pots. Reproduction by cuttings is difficult and little used.

Diseases, pests and adversities

- Aphids: attack leaves, flowers and new growing shoots. They suck the sap and make the plant sticky. They are eliminated by washing the plant and treating it with specific insecticides.

- Rust: it is caused by a fungus and is manifested by the appearance of dark pustules on the stems and leaves. In the event of a strong attack, the plant can dry out and die. It is fought with specific products. Rust resistant varieties are: "Harrison's Rust Resistent", "Scarlet Monarc", "Yellow Monarc" etc.

- Snapdragons mold: it is caused by a fungus (Peronospora antirrhini), which attacks young plants in particular, causing deformation of the leaves, which curl and become covered with a greyish mold, and stop the growth of the specimens affected. It is fought with specific products.

- Gray mold: it is a mushroom (Botrytis cinerea) that causes the appearance of dark spots and, subsequently, of gray powdery clusters on flowers and stems. It is facilitated in its spread by very dense plantations. It is necessary to eliminate the affected parts and any "moldy" soil, as well as treat the plant with an anti-cryptogamic product.

- Foot rot and root rot: they are caused by fungi that attack the collar area and roots. The affected parts become dark and rot. They are fought by eliminating infected plants, avoiding stagnation of water and using specific products when necessary.

- Seedling seed rot: caused by a fungus (Pythium debaryanum), affects newly born seedlings at the height of the collar, which becomes whitish and wrinkled. The seedlings wilt and die quickly. It is necessary to avoid hot and humid environments without ventilation and too thick seed beds and, if necessary, use specific products.
