Every time we buy a sizable new plant, we also get a new black plastic pot. While it's nice to have a stock of old containers handy when we're dividing, moving or giving away plants, they can really start to pile up. Rather than saving them "just in case," here are nine smart ideas for putting them to good use.

Prop Up Small Containers
Containers are great ways to keep color in the garden border, but we don't always have large-scale containers and smaller containers can get lose at ground level. Use an overturned five-gallon plastic container as a base, to lift the planter above neighboring plants. The black color will virtually disappear into the surrounding foliage.
It's best to use the more rigid black pots for this or double up pots with flexible sides so that they don't collapse when the planter is heavy with water. A lightweight potting soil will also help. Another bonus of lifting the planter higher is you don't have to bend to water it.Continue to 2 of 9 below.

Shake and Disperse Fertilizer
Smaller plastic containers make great shakers. The hole at the bottom will slowly sift fertilizer, animal repellent, and other granular material. You can just scoop up what you need and wave it about. Make sure you either scoop right next to the bed you'll be fertilizing because it's going to start flowing out immediately.Continue to 3 of 9 below.

Protect Your Mulch
Mulching is no one's favorite chore, but you know it's worth the effort. It helps to speed things up by dumping the mulch into the bed, rather than spreading it carefully around. But you don't want to bury your plants. You can protect them by covering each one with old plastic containers, before you dump, and then lift them when you are finished. This way you don't run the risk of burying them or getting the mulch too close to their crowns.Continue to 4 of 9 below.

This is a bit of a no-brainer. Very often the only thing handy when you are filling pots is the container you just took the plant out of. How nice that it makes the perfect potting soil scoop. Thin, rigid edges make for the best scoopers.Continue to 5 of 9 below.

Use Them as Liners for Containers Without Drainage
We're always cautioned not to use containers with no drainage holes. Of course, the soil needs to drain, but some of those ceramic, metal and concrete containers are too nice to pass up and who wants to ruin them by drilling holes? Just find a plastic pot that fits easily inside the solid container and raises it a bit from the bottom with something like stones. Lift the liner occasionally to check that there is no standing water. If there is, empty it and water less frequently.Continue to 6 of 9 below.

Protect Plants from Frost
When you hear that a frost is pending and you are not ready to lose your favorite tender plants, cover them for the night with old nursery containers. They are like instant row covers. Once it warms the next day, remove the pots and the plants will still be in good condition. They provide enough insulation to get them through several early season threats.Continue to 7 of 9 below.

Create Durable, Light Weight Filler
It's nice to give your potted plants as much soil to grow in as possible, but some containers become excessively heavy when filled with soil. Until the pot fills with roots, they can also become water sodden.
Overturning a plastic container in the bottom of the larger pot will cut down on the amount of soil needed and the weight. If there is room around the side, you can fill them in with plenty of bunched up newspaper. The newspaper helps to hold moisture and it eventually decomposes, making room for expanding roots. Don't worry, it's perfectly safe to recycle the newspaper in the garden.Continue to 8 of 9 below.

Make a Permanent Planter
If you like to swap out container plants seasonally, right in the garden bed, you can make it easier on yourself by creating a permanent planting hole. Dig a hole and insert a black plastic pot that is larger than the containers you will be swapping out. Then you can just sink and lift the seasonal plants as needed. This is especially nice if you like to add color around shrubs. Bury the liner when you plant the shrubs and you will never have to disturb their roots. Once again, the black color will help the pot completely blend in.Continue to 9 of 9 below.

Paint and Pot Them
There's nothing that says you can't use old pots as pots. If they aren't going to be seen because they will be hidden behind other containers or under vines, you can use them as is. To spruce them up you can always paint them.
Clean the pot well and then roughen the surface with some sandpaper, so the paint will adhere better. Spray paints work much, much better than trying to brush paint on. A coat or two of primer and then two to three coats of paint, followed by a sealant should do it. You can get creative with shapes, use string or tape to create patterns (remove the string or tape once the paint dries), or use one of the metal or stone paints, as was done here. The coating won't last forever outdoors, but you should get a few seasons of use before you need to touch them up.
