Paul from Dade, Florida writes
Boracare is labeled to be applied with a paint brush. 1:1, 1:2, 1:3 and 1:4 mixture ratios must be used within 24 hours to prevent the product from degrading. A 1:5 mixture ratio can remain stable for up to 30 days. You should do your best to only mix enough solution for the job you are doing that day to prevent having to discard any solution. Any unused solution can be dumped out right up against the foundation of the structure taking care not to get it on plants.
