Planting Guide

When to Plant

Start seeds indoors six to eight weeks before the last expected frost. If directly sowing into your garden outdoors, sow seeds once the danger of frost has passed and the soil has warmed.

Where to Plant

If directly sowing your seeds or transplanting your seedlings outdoors, choose a full sun location that has well-draining soil.

How to Plant

Use a loam-based potting mix for best results. Place the seeds in a bright spot with filtered light. Maintain warm temperatures around 70°F to 75°F. Sow seeds on the soil surface without covering, as they require light for germination. Mist the soil gently to maintain moisture but avoid oversaturation. Seeds typically germinate in five to ten days. After they germinate, move the angelonia seedlings to a sunny windowsill or position them beneath grow lights for 16 hours a day. Once seedlings have a few sets of true leaves and all risk of frost has passed, harden them off gradually before transplanting them outdoors. Learn more about how to harden off seedlings here. If planting angelonia outdoors, loosen the soil about a foot deep and mix in some compost or aged manure to improve its fertility and drainage. Scatter seeds on the surface of the soil without covering. Press seeds into the soil for good seed-to-soil contact. Keep the soil moist until germination. Thin to 12 to 18 inches to ensure healthy spacing.

How to Care for

Water freely but ensure the soil drains well. Once established, angelonia is drought-tolerant but performs best with regular watering. Apply a balanced liquid fertilizer monthly to encourage robust growth and blooming. Expect angelonia to produce flowers all summer long. If the plants become leggy, cut them back by half in midsummer to encourage new, fresh growth. In zones 10 and 11, angelonia can be maintained as a perennial, growing significantly larger in these tropical climates. Prune spent flowers to encourage continuous blooming. Angelonia is deer-resistant and generally pest-free, making it low-maintenance.
