lobelia

Lobelia speciosa 'Wildwood Splendor' should be watered deeply when the top inch or 2 of soil has dried out. It typically takes 1 to 2 inches of water per week, depending on your soil type and local climate. Water it in the morning and avoid watering in the evening to allow the foliage to dry before nightfall for the best disease resistance. If planted in containers, water more frequently as the potting mix will dry out more quickly. Young plants may need more frequent attention to remain hydrated. In hot climates, supplemental irrigation may be necessary during dry spells.

Lobelia speciosa 'Wildwood Splendor' needs full sun for at least 4 to 6 hours each day in order to thrive and produce vibrant blue flower blooms. It grows best in north-facing or east-facing exposure; however, it will do well in some partial shade. It is important to ensure that the Lobelia is not receiving too much direct intensity and heat from the sun as it will struggle in these conditions. It's best to plant it where it will get bright, indirect sunlight.

Lobelia 'Wildwood Splendor' should be pruned in late winter or early spring, just before new growth begins. Pruning should be done lightly, removing any dead or damaged stems. Depending on how aggressively the lobelia is pruned, it may need to be lightly pruned again mid-summer to keep it full and to encourage strong stems. If it becomes overgrown, severely prune it back to promote vigorous new growth for the following seasons. It is important not to prune more than 1-third of the plant in any 1 season, allowing for healthy new growth.
