cardinal flower

The Cardinal flower (Lobelia cardinalis 'Fried Green Tomatoes') prefers damp soil and moist conditions, so weekly watering is essential to keep it healthy and thriving. During the growing season (spring to early fall), water the plant once weekly (or more often if it is hot and dry). Be sure the soil is kept moist but not soggy. In the late fall and winter months, reduce the frequency of watering to about 1 to 2 times per month. Keep the soil moist but avoid overwatering, as this can lead to root rot and leaf spot.

Cardinal flower (Lobelia cardinalis 'Fried Green Tomatoes') grows best in full sunlight for optimal development and bloom production. In gentle climates, the cardinal flower will bloom during prolonged periods of full sunlight throughout the spring and summer months. In areas with intense sunlight and summers, the plant may benefit from partial shade in the afternoon to avoid sun stress and scorching. The cardinal flower should receive 6-8 hours of direct sunlight daily.

Cardinal flower should be pruned in the early spring before it begins to send up shoots. Wait until after the flower has bloomed and the leaves have wilted, then prune away the flower stalks and any damaged, dead, or diseased foliage. Pruning should only be done when necessary; when removing dead or damaged foliage, cut the plant right back to the ground. Avoid pruning too much, as this will reduce blooming potential in following years.
