| 1. | All season | ***Mow weekly at 6-9 cm (2.5 to 3.5 inches); retain clippings (by use of mulch mower or throw mower); or at shorter intervals when grass is growing very quickly. Mowing height can be reduced to approx. 4 cm (1.5 inches) in the late fall to reduce grass shelter for chinch, and fungal disease problems. | Cultural Controls:
2 Mowing

| 2. | May | **Judge fertilizer needs in spring by appearance of the grass. Limit nitrogen fertilizer application in spring to 0.25 kg nitrogen/100 m2 (0.5 lb N/1000 ft2) applied in mid to late May or early June; do NOT fertilize after June 5. As possible, use an organic or slow release fertilizer; regardless, nitrogen content should not be above 10%. | Cultural Controls:
2 Mowing |
| 3. | mid-June through August | ***Water thoroughly to the full depth of the soil after 4-7 days of dry weather, the shorter intervals in mid-summer water. Water areas prone to drying out preferentially and possibly more frequently, however, let them dry substantially before re-watering. (See watering guidelines in Section VI Control Level 2.) In the event that careful attention to watering in mid-summer is not possible (e.g. because you are away), cease mowing and watering from late June to circa Aug 10 (to induce dormancy and minimize need for water). |

| 4. | July 1 to Aug 20 | ***Monitor the lawn in late June/early July; vacuum any patches followed by heavy watering and/or soap treatment (if allowed)* followed by heavy watering.( See VI Control Level 1. *Hopefully HRM will apply to the PMRA for a permit to use insecticidal soap on chinch bug and will have received that by July 1), |

| 6. | October | *Clean debris around the property in the fall. Do yard cleanup in the fall rather than the spring to reduce overwintering habitat for chinch. | Cultural Controls:
