September 2021:
- Trim back perennials like Daylilies and Iris. Divide them as needed. Make sure it is a cool, cloudy day to divide and replant, or pot up for your neighbors or fall plant exchanges.
- Buy and plant spring flowering bulbs. Your efforts will be rewarded next spring. Check out Botanus on line at www.botanus.com. Add a little bonemeal fertilizer or special bulb food to the bottom of the planting hole. Water well after planting to start root growth.
- Take a critical look at your garden. Then fill in any gaps that may have developed with new perennials, shrubs and/or evergreens. They will get a huge head start over plants planted next spring.
- Bring in house plants when the evenings start to cool down. First give them a thorough spray with insecticidal soap so that there are no unwanted hitchhikers coming into your home.
- With cool nights and hoped for fall rains, it’s the ideal time for lawn repair. Dig out weeds, add clean, weed-free topsoil and re-seed. Water as required.
- Fertilize lawns with root-building “Fall Fertilizer” with a low first number (nitrogen) and a high third number (potash).
- Don’t use the lawn fertilizer you have left over from the spring, probably with a high first number (nitrogen). Save it for early next spring.
- It’s been first, a dry summer and then lots of rain, so water perennials, shrubs, evergreens and trees deeply. Dig a little test hole, say 14”-16” deep. Check moisture levels at that depth. If the bottom of the hole is dry, water weekly until frost.
