Frequently Asked Questions

2. Do I need to protect my plants from frost in September?
As September brings colder nights, it is important to protect your plants from frost. Frost can damage or even kill tender plants. You can cover your plants with blankets, sheets, or frost cloths in the evenings to provide some insulation.

Bulbs like tulips, daffodils, and hyacinths need a period of cool temperatures to establish their roots before winter sets in.

4. Should I fertilize my plants in September?

Be sure to choose trees and shrubs that are suitable for your specific climate and soil conditions. Dig a hole that is wide and shallow, loosening the soil to encourage root growth. Water the newly planted trees and shrubs thoroughly, and mulch around the base to conserve moisture and protect the roots from temperature fluctuations.
