Lobelia 'Sparkle DeVine' should be watered well enough to keep the soil evenly moist, but not so much that the root ball becomes soggy. Water the plant every 5-7 days, allowing the top 1 inch of soil to dry out before watering again. In the hotter months, it's best to water every 5 days, and in cooler months, water every 7-10 days. Make sure to check the soil before watering to ensure it is not too dry or too wet.

Lobelia 'Sparkle DeVine' needs direct sunlight for 4-6 hours a day in order to stay healthy and vibrant. The direct sun should be during the mornings for the best results. It can tolerate partial shade for part of the day, but too much shade can cause the plant to struggle and produce fewer flowering. It is important to note that Lobelia 'Sparkle DeVine' can be sensitive to heat, so it is best to keep it in an area with some shade during the hottest parts of the day in summer months.

Lobelia 'Sparkle DeVine' should be pruned in early spring and again in late summer to early fall. Prune the stems to just above a leaf node, cutting back to a healthy bud, as this is where growth will originate. Pruning in early spring will help keep the plant's shape and encourage new growth. Pruning in late summer will help to tidy up the plant and maintain its shape going into the colder months. Older plants may require more pruning to maintain their shape and promote new growth. Overall, lobelia should be pruned no more than 1/3 of each branch at a time. This will help to encourage new growth and maintain the overall shape of your plant.
