- Fall is the ideal time to divide and plant perennials, particularly Iris, Daylilies, Peonies and many other perennials. Share extra plants with neighbors.
- Buy and plant spring flowering bulbs. You will be rewarded next spring. Check out Botanus on line at www.botanus.com. Add a little bone-meal fertilizer or special bulb food to the bottom of the planting hole. Water well after planting to start root growth.
- Fill in any gaps that may have developed in your garden with new perennials, shrubs and evergreens.
- 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 fall rains, it’s the ideal time for lawn repair. Dig out weeds, add clean, weed-free topsoil and re-seed.
- 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.
- Trim back perennials and divide them as needed. Make sure it is a cool, cloudy day to divide and replant – add Bone Meal when planting and water well.
- Even with the rain we have had, water perennials, shrubs, evergreens and trees deeply. Dig a little test hole, say 14” deep. Check moisture levels. If the hole is dry, water weekly until frost.
