What St Charles soil means for your lawn care
Your silt loam holds moisture well (sometimes too well), so water deeply but less often. That high calcium content can lock up nutrients, making spring fertilizing trickier than it looks. One common mistake: overwatering cool-season grasses during humid stretches, which rolls out the welcome mat for fungus.

Why fall seeding wins in Kane County
Early September gives grass roots time to establish before frost, while spring plantings often struggle against summer heat. Prep soil with a quick test, keep watering consistent (but not soggy), and avoid the classic mistake of seeding too late in fall. Need help choosing?
