watering

Fennel (Foeniculum vulgare 'Purpureum') should be watered when the top 1”-2” of the soil is dry to the touch. Depending on the temperature and humidity, fennel should be watered around once or twice a week. When watering your fennel, make sure to water evenly and give it enough water so that it can properly soak into the soil. It is best to water your fennel early in the morning so that the water can soak into the soil throughout the day, otherwise the water may evaporate from the sunlight. Do not over water your fennel as it can ruin the soil and affect the growth of your plant.

sunlight

Fennel (Foeniculum vulgare 'Purpureum') should be grown in full sun or light shade. When grown in full sun, it should receive 6 to 8 hours of direct sunlight per day. If grown in partial shade, it should only receive 3 to 4 hours of direct light each day. As with other plants, too much direct sunlight can cause the leaves to burn.

pruning

Fennel (Foeniculum vulgare 'Purpureum') should receive light pruning throughout the growing season. After the main flush of growth in spring, prune the fennel back to 1/2 of their original size. This will help to encourage bushier growth and more foliage. Then in late summer, prune the plants back to promote a second round of growth before winter arrives. Deadhead any spent blooms as they appear. Finally, in early spring, cut back any dead or overgrown stems to the base.
