Landscape Calendar Tips

Home Grown  by Keith Reed
Last week we discussed the importance of timing when it comes to effective weed control. I can’t emphasize enough just how much difference this can make when it comes to ensuring a successful landscape. If you missed last week’s column, please go back and take a look, as good weed control opportunities are just around the corner.

Insects and disease are two more classes of pest that are best controlled with proper timing. However, problems caused by these issues can vary widely from one year to the next and it is important to understand that treatment may not be necessary just because the calendar suggests it.

The best plan of action is mark the calendar for times of the year when these pests typically cause problems, not as a reminder to automatically treat, but a reminder to be on the look-out should the insects or disease become bad enough to warrant treatment. This is a key component of the concept of Integrated Pest Management (IPM).

While many common landscape tasks are on-going or can be done at any time, some of these are also calendar dependent. The OSU Extension service offers fact sheet
HLA-6408 Landscape Maintenance Schedule as a good all-purpose document to highlight many of these tasks as well as providing dates for common insect and disease problems. This schedule also references a number of other fact sheets for those of you interested in a specific crop or group of plants (turf care for example).
