- Prune winter-damaged stems from perennials
- Begin deep watering newly planted natives as weather warms
- Water newly planted natives deeply once weekly during first season
- Provide established natives with deep watering every 2-3 weeks during extended drought
- Deadhead for extended bloom if desired, but leave seed heads for wildlife
- Monitor for rare pest issues (generally minimal with natives)
- Enjoy peak bloom period and pollinator activity
- Apply mulch to conserve moisture if needed
- Plant container-grown natives in September for spring establishment
- Scatter native wildflower seeds in prepared beds
