Do you check plants that are in storage every now and then? They can be given a little water once in a while but water sparingly. You are better off not giving them any plant food just yet. It is also best to air the area they are being kept every now and then but make sure you do this on frost-free days!
Winter is here again and many birds have headed south. The birds that stay here for winter often do so around towns and in our gardens. They have learned that in hard times they are more likely to find food there, than in the woods or fields.
