One of the most important aspects of taking care of your plants long-term is choosing the right pot size. With this guide, you will discover the best size pot for your houseplant and keep it happy for years to come.
In this plant care guide, we will look at why choosing the right pot size is important, whether a pot can be too big or small for a plant, how to measure the plant pot size, and what the right size pot is for your plant.
These are the topic we're going to look at:
In my experience, choosing the best size pot for a plant is sometimes tricky. There are a few things you have to keep in mind when picking out the right size of a pot. This guide will help you get through the complicated world of plant pot sizes and will make you more confident in your ability to care for your houseplants. So, let's get started!
Why is choosing the right pot size important?
Are you wondering why it's important to choose the right size pot for your plant? You're not alone! It's one of those things you never really think about when you're first starting with taking care of plants.
Choosing the right pot size is important because it affects the health of your plant. If the pot is too small, the roots will become crowded (called rootbound), causing stunting growth and could even kill the plant.
If the pot is too large, the soil will retain too much moisture and the roots will start to rot if you're not careful, which can also kill the plant. Another, perhaps less important, factor is that a giant pot could be too heavy for you to move around throughout the year.
How can you tell if a pot is too big or too small for a plant?
You know the size of the pot is important, but how do you know if the size of the pot is too small or too large? Let's find out!
How can you tell if a pot is too small?
The best way to know if a pot is too small for your houseplant is by looking at the roots. If you can see that the roots are starting to grow out from the bottom of the pot, or if you can feel them pushing against the sides of the pot, it means that it's too small for your plant.
Another great way to see if your plant might be ready to be repotted is by carefully lifting it out of the pot and seeing if the roots are circling the bottom of the pot. They circle the bottom of the pot because these roots have nowhere else to go. This is a clear sign that it's time for a larger growing environment.
How can you tell if a pot is too large?
You can tell if a pot is too large for a plant by looking at the amount of soil in the pot. If the roots of the plant are more than 2 inches below the top of the soil, the pot is likely too big for this plant.
Another great way to find out if the pot might be too large for your plant is to look at how long it takes before the soil dries out. If the soil is well-draining but stays moist for more than a week, the pot is probably too large. In this case, the plant is too small to be able to absorb all that moisture from the soil in a few days. Most plants don't like the soil to stay this moist for so long and could develop root rot.
When the pot is too large and the soil stays moist for too long, you might also notice that your plant starts to show signs of being overwatered, even if you haven't watered it in more than a week. This is your sign to move your plant to a smaller pot.
How do you measure the plant pot size?
If you're still here, you've probably found out that your plant needs to be moved into a different pot. Maybe you'll need to find a larger one, maybe a smaller one. But how do you measure a plant pot?
Luckily, this is quite simple. All you'll need is a tape measure or ruler. Measure the diameter at the top from one side to the other and then measure the height from the bottom of the pot to its rim. This will give you two numbers, which is how you can determine the size of a pot.
The depth of the pot is important for the type of plants you're going to use this pot for. For example, a shallow pot is great for plants that you want to keep small or plants that don't grow their roots very deep in the soil. These types of pots are great for Bonsai trees, succulents, or cacti.
A deeper pot is perfect for plants that grow large roots and those more thirsty plants, like a Monstera or an Alocasia Zebrina. These plants grow tap roots, which go deep into the soil to look for water.
Now you know how to measure a pot, let's look at the right size pot for your plant.
What is the right size pot for my plant?
The right size pot for your plant will depend on the size of the plant, as well as the size of the root system.
As a general rule of thumb, the pot should be 2-3 inches larger in diameter than the width of the plant's root ball. For example, if the plant's root ball measures 6 inches wide, you should choose a pot with a diameter of 8-9 inches.
The depth of the pot is also important as we've discovered in the previous section. A good rule of thumb is that the pot should be 1-2 inches off the bottom of the pot and the roots shouldn't be deeper than 1 inch from the top of the soil.
This depth should give your plant plenty of space to grow, without having too much soil in the pot and causing problems later on.
