This page is for readers in Illinois US with towns that begin with the letter L.
To adjust your dates, click the downward arrow ()
in the box below. Click on your town from the list shown then click the “CLICK
HERE TO SET DATES TO SELECTED TOWN” box below.

If your town begins with L and it is not in the list above then send us an email using the form at the end
of this page and we will do our best to include it. Please specify the state as well as the town
/ city.

Only ask for your town to be added if you are sure that it is not in the list above.

You can manually set the frost dates if you believe the dates we give
are not appropriate for your town. Click
here to choose a more appropriate frost date, then select
Manual 1 (last frost = last week of March), Manual 2 (last frost = 2nd week
April), Manual 3 (last frost = last week April), Manual 4 (2nd week May) or
Manual 5 (end May / early June).

After you have set your frost date, check it out by looking near the top right of
this or any page in GardenFocused. If it’s set correctly then you know we have set all
dates to suit your area. Occasionally your settings can get lost over
time although this is unusual. If this happens then simply return to this page
and reselect your town.
