Is it Time to Repot?
Wednesday, January 11th, 2012You have been enjoying lovely indoor plants growing in your windows all winter long. With spring a bit closer you may be antsy to get your hands dirty again and now may be the perfect time. To grow and thrive, plants need to be in a container that allows their roots to take in moisture and nutrients from its growing media. Your plants may have out grown their living environment and be ready for a change.
How do you know it is time to repot?
It is a good idea to check your plants before the longer days and more sunshine trigger a spring growth spurt. If you see roots poking through the drainage holes, if water runs quickly through the pot because there is no soil left to retain it, if the pot is very light and the plant is top heavy, then it is time to repot.
To get started, a few hours before you plan to transfer the plant, water your plant so that the roots will be less voulnerable when they make the transition.
Choosing your pot
Next, you need to choose your new pot. Containers are typically measured in diameter, the distance across the top opening. According to Guide to Houseplants, you want to find a pot that that is only one or two inches larger than your old pot. So, if your plant had been in a four inch container, the largest container you should transfer the plant to should only be six inches. If you use a pot larger than this your soil may retain too much water, causing root rot and hindering your plant from thriving.
If you are reusing any previously used pots, be sure to disinfect the pot before transferring. This will reduce the risk of transferring pests and diseases from plant to plant.
Now that you have your container and your plant ready for repotting, you can choose your soil mix. You can purchase a potting mix made specifically for your variety of plant from a landscape or garden store, or you can mix your own. For potting mix ideas see this previous post.
Making the transfer
Now it is time to remove your plant from its old container. Gently tip the container and tap the sides to loosed the soil and roots. Pull the plant out and shake loose any soil. Roots that are coiled on the bottom can be gently pulled straight out or pruned. Plant Care suggests you,
”score the rootball vertically with a sharp knife in several places, cutting into the rootball about an inch as you slice from top to bottom.”
These actions will help the roots adjust quickly and begin growing in their new medium.
Next, place a few inches of the potting soil in the bottom of the new container. Now check your plant to make sure it will be at a depth equal to what it was in its old container. You do not want the plant too deep in the container, but you also do not want the root ball to be exposed over the rim. Once your plant is situated correctly fill in the potting soil around it, tamping it down to remove any air pockets.
To finish, water your plant thoroughly. Guide to Houseplants advises that you not fertilize your plant for the first month in its new home. This will allow the roots to become established and protect them from fertilizer burn.
