With the onset of winter, pasta and potatoes seem to be on the menu quite often at our house. If you aren't able to bring in melted snow to water your plants, try saving the water from your dinner prep. Your plants will think it's nutritious and delicious! The plants will enjoy the drink from a starchy pot of water; the only catch is to make sure it has cooled. One of the easiest, non-toxic ways to kill weeds is boiling water, so if you don't wish to repeat those effects, let your pot cool on the stove until after your meal.
Simply fill your watering cans with what you can and fill any drip trays with the remainder. The used water is like a Vitamin Water for your plants and you'll be able to get a little more use out the water each time you cook!
