There are some great landscape upgrade tasks you can do in spring, before it gets too hot. One is top-dressing weak lawns with a thin layer of soil and over-seeding; another is planting new hedges. One install project this week involved replacing dead cedars (Thuja occidentalis 'Smaragd' with yews (Taxus). Yews seem to do better than cedars in our West Coast landscapes, although we also planted some cedars.
If your lawns are limed and aerated, definitely consider making some changes to your landscape by improving your lawns and planting something new. Have some fun with your landscape!
