What are the Signs My Plant is Ready for a Bigger Pot?

A good indication that your plant is ready for a bigger pot is if it has grown quite a bit since its last transplant and needs watering much more frequently. In some cases, your plant may even begin to show signs of underwatering (leaves browning, soil pulling away from the edge of the pot, etc.). You may also begin to see roots emerging from drainage holes. If any of these are occurring, it is a good idea to inspect the root system by gently removing the plant from its pot. The roots should be a healthy white or yellow color; they will be tightly coiled around the length of the pot if it is ready to be moved up. This is what is known as being root-bound.

When to Wait:

Keep in mind that once you give your plant space to stretch out, it is going to focus on re-establishing its root system. Due to this, you will likely not see any new foliage growth for a bit. This is also the reason why you want to wait to re-pot anything with blooms; the plant will redirect its energy from above the soil to below, abandoning any flowers it was producing. Another instance in which you would want to wait to up-pot is if your plant is new to you. Changing environments adds stress to plants, so it is best to wait two to four weeks to allow your plant time to adjust to its new home before adding any additional stressors.

Finding the Right Pot:

You only want to increase your pot size by one or two inches in diameter and about one inch in depth from its current container. Moving up any more than this creates a scenario where the root system is too small to absorb the water you give the plant in an adequate amount of time, leaving the roots to soak and suffocate. One may think that giving the plant less water would remedy this, but unfortunately, you put the plant in a situation where the water sits out of reach from the roots.

The material you choose for your pot is up to you, however, we recommend keeping your plant in a plastic grower’s pot and then setting that into ceramic pottery. Grower’s pots are great for keeping your plant in because they have wonderful drainage and allow for better access to check root health. If you do wish to plant directly into a ceramic or decorative plastic pot, it is best to choose one with drainage holes. Alternatively, you can line the bottom with a half-inch layer of grower’s charcoal, an antibacterial soil additive that will absorb excess moisture. Others prefer to plant in terracotta pots which are often inexpensive and help to naturally wick away moisture from the soil. 

We suggest using Uni-Gro Premium Charcoal. We have this product for purchase in our retail store. You can also find similar charcoal products in a nursery or gardening center near you.

 

Repotting Steps:

Step 1: Gather the materials you will need:

  1. Your properly sized pot,
  2. Your desired soil mixture,
  3. Sterilized shears, and, if applicable,
  4. Grower’s charcoal.

Step 2: Add a half-inch layer of fresh potting soil to the bottom of your new container. (Note: If your container is non-draining you will want to add the half-inch layer of grower’s charcoal before this step). [Fig.4]

Step 3: Take this opportunity to snip off any unhealthy, dark, and mushy roots using your sterilized shears. You may also choose to gently massage the end of the roots to loosen them up. It is usually not necessary to break up the roots completely.

Step 4: Place your plant into its new container. Use one hand to steady the plant while you use the other to fill the soil around the roots to the level in which the plant was previously buried.  You will want to leave about a half-inch clearance between the top of the soil and the lip of the pot to allow for soil expansion during watering.

Step 5: Gently water your plant and place it in an area with suitable light. [Fig. 6]
