lobelia

The amount and frequency of water required for the Lobelia 'Rose Beacon' will vary depending on growing conditions, but as a general rule, this plant should be watered when the top 2 inches of soil are dry. If planted in a container, water whenever the soil is dry to the touch, and if planted in the ground, water only when the soil is dry to a depth of 2 to 3 inches. Avoid over-watering as Lobelia 'Rose Beacon' is susceptible to root rot. When watering, water thoroughly until the water begins to drain from the bottom of the pot or soil bed.

Lobelia 'Rose Beacon' grows best when given full sun, meaning at least 6 hours of direct sunlight each day. The best time of day for sunlight to reach the plant is during the morning and early afternoon. It prefers the temperatures at this time to be warm but not hot. Avoiding harsh, direct afternoon sunlight is important since it can damage the plant's foliage. If possible, grow this plant in a spot that receives morning sun and late afternoon shade.

Lobelia 'Rose Beacon' should be pruned in late winter or early spring. Only the dead or diseased branches should be removed. Pruning should be kept to a minimum, as this species is a naturally-dense, semi-trailing plant. Regular pruning of Lobelia 'Rose Beacon' will result in fuller plants with more blooms.
