Pelargonium zonale, commonly known as the zonal geranium, is a member of the Geraniaceae family. Native to South Africa, it is a popular ornamental plant known for its vibrant flowers and rounded leaves with distinct zonal markings. It thrives in subtropical climates and can be grown as a subshrub or shrub. The plant undergoes a dormancy period of about 2 months.
Pelargonium zonale requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and average humidity levels. Water the plant when the soil partially dries out, ensuring it does not remain waterlogged. Regular pruning helps maintain its shape and encourages blooming.
土壌
This plant prefers well-draining loamy soil. A mix that retains some moisture but allows excess water to drain away is ideal. Ensure the soil is slightly acidic to neutral in pH.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to support healthy growth and flowering.
植え替え
Repot Pelargonium zonale every 1-2 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Repotting is best done in the spring before the growing season begins.
伝搬
Propagate Pelargonium zonale through stem cuttings. Take cuttings in the spring or early summer, allow them to dry for a day, and then plant them in a well-draining soil mix. Keep the cuttings in a warm, bright location until they root.
剪定
Prune the plant regularly to remove dead or yellowing leaves and spent flowers. This encourages new growth and maintains the plant's shape. Pruning is best done in the spring and summer.
毒性
Pelargonium zonale is generally non-toxic to pets and humans. However, ingestion of large quantities may cause mild gastrointestinal discomfort. It is always best to keep plants out of reach of pets and children.
追加
To encourage bushier growth, pinch back the tips of the stems. This will promote lateral branching and result in a fuller plant. Regular deadheading of spent flowers will also encourage continuous blooming.
