Getting The Best Results When Growing Plants In Pots

Last Updated On: February 8, 2023

One of the first things to consider when deciding to start a garden is where and how to plant your plants. Many gardeners take into consideration the lighting, soil type, and location, but many times overlook the actual container used to house the plant. While the other items are extremely important, understanding the container you are using can be just as important for optimal growth.

Today, we will focus on one of the most popular container types for both indoor and outdoor gardening, the terra-cotta pot. These pots are usually very cheap and easy to obtain making them an excellent first choice for many gardeners. However, there are some things to keep in mind when using them to ensure your plants reach their maximum potential.

Start With The Size

The first thing to keep in mind when using terra-cotta pots, as well as any type of container, is the plant’s optimal grow size. The size of the pot is going to be a limiting factor in the size your plant grows to. So if you’re looking to grow a large plant then you’ll need a pot sized to match. The opposite is true if you wish to grow a smaller plant.

In many cases, you’ll need multiple pots as your plant grows. Many plants like to be planted in a pot that is only slightly bigger, which gives them just enough room for growth. Then, you’ll need to repot them, usually every 1-2 years, as they outgrow the container.

Clay pots come in a wide variety of sizes, so you’ll usually be able to find one that fits your needs. Be sure to get one that is both wide enough as well as deep. Deep roots plants for example generally need a taller pot to allow for proper room for root growth.

Ensure Clean Pots

Next, always make sure the pot you’re using is clean; especially if you’re reusing a pot from outdoors. Scrub out any dirt or debris, and allow the pot to soak in warm, soapy water overnight. This prevents the spread of any sort of disease or pests from older plants to your new ones. You’ll also want to do this even when purchasing from a store to ensure there’s not a nasty surprise waiting in the form of pests.

Before adding your soil you can also add a few inches of pebbles or gravel. This helps promote proper drainage and is important for many plants that are susceptible to overwatering. This also helps with airflow in the soil which helps prevent mold growth.

Water Whisking

One of the most interesting attributes of clay pots is their ability to whisk water out of the soil. This is due to the porous nature of the clay. Generally, this is a good thing, and helps prevent overwatering your plants. Most plants don’t like to be sitting in too damp of soil and this property will help prevent that.

You do want to be careful though. This water-whisking property means that your soil will naturally dry out faster. This can sometimes lead to underwatering issues, so make sure you’re keeping up with your plant’s needs!

Why Are My Pots Turning White?

A common issue many people using clay pots for the first time bring up is the buildup of a white material on the outside of the pot. Rest assured that this is completely normal, and won’t harm your plants in any way.

This is actually the result of calcium and other minerals in the water being absorbed into the clay. It’s a natural process as the clay whisks away water and some of the minerals are left over. It’s not harmful to your plants, so it’s nothing to worry about.

If you dislike the look you can use some warm water and a stiff brush to gently remove the buildup. This is usually enough to remove it and make your pots look brand new.

terra cotta pot

At the end of the day, terra-cotta clay pots are an excellent choice for a variety of plants. They are very popular and cheap while still providing a perfectly healthy environment for your plants to grow. If you keep the above tips in mind, you’re sure to be growing beautiful plants in no time!
