While it may still be a bit warm outside, autumn is definitely right around the corner. While you are outdoors enjoying the seasonal shift, here are some September garden tasks you should check off your to-do list:
Vegetables: Plant on time! Be sure to plant cole crops, leafy greens, and root vegetables this month. Timing will depend on your zone. Consider planting crops in successions to spread out harvest for extended consumption.
Fertilizing: Plants are tired from the long hot summer. Refresh them for fall with a good dose of appropriate fertilizer to promote healthy strong root development. Also consider amending beds with compost to boost soil microbes.
Planting and dividing perennials: This is one of the best times to make additions to your garden. Visit your local nurseries for beautiful fall perennials for the best selection. Go ahead and divide any overgrown spring and summer blooming perennials; you can plant divisions in different locations in your garden or share with your friends.
Bulbs: Along with dividing your perennials this is the perfect time to divide any spring-blooming irises you may have in your garden. Bulk iris are also becoming available in your local nurseries so don’t forget to plant for spring color. As always, pay attention to the variety of bulb and temperature requirements for planting for best results.
Cool Season Color: Fall blooming annuals are showing up at the garden centers. Take advantage of the change in plant selection and refresh your summer color. Planting cool season color on-time will result in stronger plants throughout the growing season.
General Maintenance: Continue cutting back perennials and performing basic garden clean up as needed. September is also a good time to mulch beds as well for winter preparation.
