Fennel is a herbaceous perennial plant that is native to the Mediterranean region. It has been used for centuries as a culinary herb, and it is also known for its medicinal properties. Fennel plants can grow up to six feet tall, but the height of the plant depends on various factors, including the growing conditions and the cultivar.
Factors that Affect the Height of Fennel Plants
Growing Conditions
Fennel plants require full sun and well-drained soil to grow well. The soil pH should be between 6.0 and 7.5. Fennel plants grow best in warm climates, but they can also tolerate cooler temperatures. They require regular watering, especially during the first few weeks after planting. Fertilize the plants with a balanced fertilizer every four to six weeks.
Cultivar
There are two main cultivars of fennel: sweet fennel (Foeniculum vulgare var. dulce) and bronze fennel (Foeniculum vulgare var. purpureum). Sweet fennel grows taller than bronze fennel, reaching up to six feet tall, while bronze fennel grows up to three feet tall.
How to Grow Fennel Plants
Planting
Plant fennel seeds in the garden after the last frost date in your area. Sow the seeds directly into the soil, about half an inch deep and one inch apart. Thin the seedlings to six inches apart when they reach a height of two inches.
Care
Water the plants regularly and fertilize them with a balanced fertilizer every four to six weeks. Mulch around the plants to retain moisture and suppress weeds.
Harvesting
Harvest fennel leaves when they are young and tender, usually around eight weeks after planting. Harvest the seeds when they turn brown and start to fall off the plant.
