Care Guide

Cydonia plants are relatively easy to care for and can thrive in a variety of conditions. Here are some tips for caring for your Cydonia plant:

Water

Cydonia plants prefer well-draining soil that is kept moist but not waterlogged. Water your plant regularly, especially during the growing season, and make sure the soil never dries out completely.

Fertilization

Feed your Cydonia plant with a balanced fertilizer once a month during the growing season. Avoid over-fertilizing, as this can lead to excessive vegetative growth at the expense of fruit production.

Soil

Cydonia plants prefer well-draining soil that is rich in organic matter. They can tolerate a wide range of soil types, but prefer slightly acidic to neutral soil pH (6.0-7.0).

Sunlight

Cydonia plants prefer full sun to partial shade. They can tolerate some shade, but fruit production may be reduced in shady conditions.

Hardiness Zones

Cydonia plants are hardy in USDA zones 5-9, which means they can tolerate temperatures as low as -20°F (-29°C) in winter.

Common Pests & Diseases

Cydonia plants are relatively resistant to pests and diseases, but may occasionally be affected by the following:

• Fire blight: a bacterial disease that causes wilting and blackening of the leaves and branches.
• Cedar apple rust: a fungal disease that causes orange, gelatinous growths on the leaves and fruit.
• Aphids: small, soft-bodied insects that suck sap from the leaves and can cause stunted growth and leaf curling.

Habitat

Cydonia plants are native to southeastern Europe and western Asia, where they grow in a variety of habitats, including woodlands, scrublands, and rocky slopes. They prefer well-draining soil and can tolerate drought, but may not grow well in extremely hot or humid conditions.
