Same, but by next week it will all melt - I want to be prepared.

I want to know what to use for lawn/grass - not mulched areas.

There is a kind of Preen that is designed for lawns. Different package than Preen for bedding areas.

January is too soon. By March it is too late for some weeds.


What brand do you use?

Saw some forsythia blooming in NW DC yesterday! I prefer Green View brand after using Scott’s for many years.

I thought it was when the forsythia bloom, so early March.
