Establishment
3-6 monthsYoung plant with initial foliage growth; root system developing
Water regularly but allow soil to dry between waterings. Protect from harsh winds. Mulch around base, keeping away from stem.
Vegetative Growth
6-12 monthsIncreasing branch structure, dense foliage development, lemon-scented leaves
Prune lightly to encourage branching and fuller shape. Remove crossing or diseased branches. Fertilize sparingly in spring.
Flowering
2-3 months, typically spring/early summerWhite brush-like flower spikes emerge along stems; lemon fragrance most pronounced
Do not over-fertilize with nitrogen, which reduces blooms. Provide adequate water during flowering but maintain good drainage.

Leave seed capsules on plant for wildlife habitat. Prune only to remove dead wood or shape plant.
Maturity
