Growing Requirements for Angelonia
- During the growing season of Angelonia, keep weeds under tight control. Weeds compete with plants for water, space, and nutrients, so keep them under control by cultivating them frequently or covering them with a mulch to prevent their seeds from germinating.
- Mulches can also aid in the retention of soil moisture and the maintenance of consistent soil temperatures. An organic mulch of shredded leaves around annual plants gives the bed a more natural appearance while also improving the soil as it decomposes over time. It should never be placed directly on the stems of plants to avoid rot.
- Continue to keep the soil evenly moist but not wet.
- Following the appearance of new growth, a light fertilizer can be applied. To avoid burn injury, grass-based fertilizers should be kept away from the plant’s crown and foliage. Lower rates of a slow-release fertilizer should be used because higher rates may encourage root rots.
- Remove spent flower heads to ensure that plants continue to bloom until the end of the season.
- Keep an eye out for pests and diseases on your Angelonia. In most cases, plants are injured or killed by frost when temperatures fall below 40F degrees. At these low temperatures, water freezes, and soil near the stems is destroyed through underwatering and freezing of ground litter. If a risk of frost still exists in late winter, plant some deciduous shrubs to fill in gaps between flowers while they finish blooming (see People’s Plant profile on Angelonia).
