Maintenance Notes

Self cleaning, no deadheading necessary. Laguna does not like "wet feet". Be sure that you do not keep the soil wet. Allow the soil surface to dry before watering again.

These newer types of Lobelia are much more heat tolerant than past plants. They will reliably bloom in warm temperatures unless night temperatures stay in the upper 70's or above. If you experience an extended time period with high night temperatures the plants may flush out of bloom, however, the plants themselves should continue to look good. If the plants do go out of flower using a sharp pair of scissors or pruning shears to give the plants a "haircut" - a slight overall trim - should encourage additional branching. Additional branching will result in increased flower power once the plants begin blooming again after night temperatures fall.

The plants may be trimmed back at anytime if you feel they could use it.

A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
