Lobelia 'La Fresco' should be watered thoroughly once or twice a week, allowing the top 2 inches of soil to dry out between waterings. Water at the roots to avoid wetting the foliage and use room temperature water. In especially hot weather, water may be needed more frequently to keep the soil from drying out completely. If the soil feels dry to the touch, it is time to water.

The Lobelia 'La Fresco' plant requires at least 6 hours of direct sunlight per day for optimal growth. The best times to provide this light are around 10 am and 2 pm. It is important to ensure that the plant does not get too much sunlight as this can cause the leaves to dry out and the plant might not survive. It is also important to keep in mind that this plant can become stressed if it does not get enough sunlight so it should be monitored closely and provided with the amount it needs for good growth.

For Lobelia 'La Fresco', pruning should be done in early to mid spring. Pruning should be done to control size and create a dense, mounded shape. You should remove up to 1 third of the overall height of the plant, and trim aside any damaged or discolored foliage. Stems and foliage can be cut to just above where healthy buds are located. This will encourage the plant to remain healthy and produce more flowers. Pruning can also be done throughout the summer when plants become leggy and blooms become sparse. Keeping a regular pruning schedule throughout the summer and early fall will ensure the Lobelia remains bushy and produces plenty of flowers.
