Pamper your indoor plants
It's winter outside but you can still flex your green thumb!
Show your houseplants a little love with a leaf wash, either by hand with a soft cloth or in the sink or shower after covering the exposed soil with an old plastic bag.
Clean leaves are more efficient at taking in sunshine---and they look nicer too.
At the end of the month start fertilizing house plants again. Regular, but very weak solutions are better for plants than occasional heavy fertilizations.
