Maintaining the Yesterday, Today, and Tomorrow plant (Brunfelsia spp.) involves care practices that support its flowering, overall health, and aesthetic appeal. Here’s a guide to the maintenance of this charming shrub:

1. Watering:
   • Keep the soil consistently moist, especially during the growing season.
   • Water when the top inch of soil feels dry to the touch.
   • Avoid waterlogged conditions, as well-draining soil is crucial.
2. Soil:
   • Plant in well-draining soil enriched with organic matter.
   • Maintain a slightly acidic to neutral soil pH.
3. Fertilization:
   • Feed the plant with a balanced, slow-release fertilizer in the spring before the growing season begins.
   • Additional fertilization may be needed during the growing season, especially if the plant shows signs of nutrient deficiencies.
4. Pruning:
   • Prune the plant to shape it, remove dead or spent blooms, and encourage a bushy and compact form.
   • Pruning can be done after the main flowering period.
   • Avoid heavy pruning, as Brunfelsia sets its flower buds on older wood.
5. Deadheading:
   • Remove spent flowers regularly to encourage continuous blooming.
   • Deadheading also helps maintain a neat appearance.
6. Sunlight:
   • Provide the plant with partial to full sunlight.
   • Ensure it receives adequate sunlight for healthy growth and prolific flowering.
7. Temperature Tolerance:
   • Protect the plant from frost if grown in cooler climates.
   • In colder regions, consider growing it in containers and bringing it indoors during winter.
8. Pest and Disease Control:
   • Monitor the plant for common pests such as aphids, scale insects, and spider mites.
   • Treat pest infestations promptly with insecticidal soap or neem oil.
   • Ensure good air circulation to prevent fungal diseases.
9. Container Care:
   • If growing in containers, use a well-draining potting mix.
   • Containers should have drainage holes to prevent waterlogging.
   • Water container plants more frequently than those in the ground.
10. Mulching:
    • Apply a layer of organic mulch around the base of the plant to retain soil moisture and suppress weeds.
11. Container Care:
    • If growing in containers, use a well-draining potting mix.
    • Containers should have drainage holes to prevent waterlogging.
    • Water container plants more frequently than those in the ground.
12. Monitoring:
    • Regularly inspect the plant for signs of stress, disease, or nutrient deficiencies.
    • Adjust care routines based on the specific needs and conditions of the plant.

By incorporating these maintenance practices into your gardening routine, you can enjoy the continuous beauty and fragrance of the Yesterday, Today, and Tomorrow plant. Tailor care based on the specific variety you have and the conditions in your garden.
