Checklist
- Flush irrigation systems. Check sprinklers and drippers; repair as needed.
- Keep adding water to pond plants to encourage early bloom.
- Feed azaleas and camellias at the end of bloom.
- Fertilize indoor plants as needed.
- Fertilize lawns, annuals, vegetables, and citrus trees as spring growth starts.
- Spray peach, apricot, plum, and nectarine trees to control hot hole fungus and brown rot.
- Check roses for black spot and rust. Prevent these diseases by watering early in the day and avoiding overhead watering.
- Look for aphids on roses. Blast them with a strong stream of water.
- Get a good start on early spring weeding.
- Prune spring flowering shrubs and trees after bloom. Be careful not to remove second and third-year growth from shrubs such as lilac, as this is where next year’s flowers will appear.
- Set out tomato plants only when night temperatures reach 50 degrees.
- Empty standing water in buckets and containers to control mosquitoes.
