Horticulture Tips for November
As November arrives, consider the following landscape and gardening tips:
- Trees can still be planted in November. If you would like to see some interesting examples of trees for good fall color, join the OSU Landscape Services team for a short (and timely) campus walk on Tuesday, November the 1st. The walk is free to attend with no registration required. It will begin promptly at 12:10 and end at 12:50 at the Chi-O Clock on the north side of the Student Union. Thanks to OSU’s Department of Wellness for sponsoring the event.
- November is a good time to make a nitrogen application for cool-season turfgrasses such as tall fescue. Actively growing tall fescue may still need mowing during this time.
- Speaking of tall fescue, one of the significant contributors to its decline is the build-up of excess leaves. While it is not necessary to remove leaves as soon as they land on the turf, it is important to prevent them from completely blocking all light, water and air movement. One of the easiest ways to dispose of excess leaves is to continue mowing and chop them into small pieces where they will easily decompose directly into the turf, providing nutrients as they go. At some point, you may still need to collect the excess, but the quantity will be much smaller and easier to manage. Well-chopped leaves also provide a nice head start to the composting process, with smaller pieces decomposing much quicker.
- Most vegetable plants should already be in the compost pile by now. Leaving plants in the garden tends to harbor pests and disease so clean up any remaining plant residue as soon as possible. You can also still plant winter cover crops, but act soon!
- This is also a good time to clean up select ornamentals. The key word here is “some”. Perennials that are a bit cold sensitive should be left alone until next spring. Pruning them now (even though they appear dormant) can set them up for winter injury. Crape myrtles and roses are common examples of plants that should not be fall pruned. Also, plants such as ornamental grasses put on their best show in the winter, another reason to delay cutting back until early spring.
- Don’t forget to winterize your tools and equipment. Putting tools away clean and sharp (with a light coating of oil) will pay dividends in the spring. Adding fuel stabilizer to small engines is also another important garden task that will pay big dividends come springtime.
- November is also a great time of year to walk the landscape and makes notes about changes you would like to make for next season while things are still fresh on your mind.
