Measure And Find The Ideal Plant Pots Like A Pro

Looking at your once beautiful plant and finding yourself hearing its voice saying, “I will survive”? Unsurprisingly, you want to understand how to provide a good home and stable growing conditions for all your houseplants

The size of the plant pot plays an essential role when it comes to its healthy growth. If you want to be sure about your greenery, then you’re in the right place! Read more about the following aspects of why and how the pot’s size is related to the plant’s growing stages.

Why are there so many sizes?

Garden nurseries nurture trees and plants. Moreover, they are needed when your plants reach different growth stages; therefore, various sizes of plant pots appear. Usually, the plants are sold in one of the following:

  1. Bare roots – trees are found in this state more often. Bareroot trees are dug from the ground when they’re dormant, usually in fall, and their roots are shaken free of soil.
  2. Value plugs – great value, and their size is about 3cm in height and 2cm wide. They need to be transplanted and cared for before they are ready for a bigger pot or transported outside in the garden.
  3. Garden ready plugs – they are prepared to be transplanted outside, having a size of 4cm height and 3.5cm wide.
  4. Large plugs – suitable for large planters, the plugs have a dimension of at least 5cm; therefore, a pot with an opening of 12cm is recommended.

Does the pot size affect your plants?

The plant needs adequate space to keep the root and the whole potted plant stable and in good growing conditions. Because most nutrients are found in the soil, the amount of dirt available provides the root system resources. If the pot is small, the root can become packed without adequate space to spread out and partly start to poke out and be visible through the pot’s drainage holes

Another way to notice if the pot is small is the look at the plant after watering. The plant can be wilted; hence, the pot’s soil cannot hold the water long enough to be absorbed proportionally with the whole plant’s needs. On the other hand, a bigger pot may be more appealing, but it could negatively affect the plant’s development; the pot’s soil will hold water for longer, leading to mould growth that causes root disease and eventually root rot.

Finally, the question is, “how to choose the proper size for your plant”? Definitely, after buying a plant, a new pot is needed to accommodate the following growing stage of it. The next size available, at least 5 cm larger, is an appropriate solution for transplanting the new plant when arriving home.

What size is the common pot?

Different flower containers, sizes, shapes, and materials are widely provided by the garden centres and nurseries. Even if they have the same volume, the container size could be more critical for some indoor plants. For example, for herbs in a window box, the recommended depth is 15cm. Instead, if you prefer your spices in a flowerpot, a top diameter of 45cm is minimum. Don’t forget to mix and match the herbs or plants in one single pot by their preference of being good companions.

Do you agree that the size of the plant makes you choose the size of the pot? Most available plant pot sizes are grouped in the following categories:

  • Small pots: A small pot’s diameter is between 9cm and 14cm, and the height is a maximum of 13 cm; usually suitable for herbs or small plants like cacti and succulents, primroses, or small foliage plants.
  • Medium flower pots: They’re measured mainly by their volume 2L to 15L with their height from 15 cm to 30 cm.
  • Larger pots or rectangular planters: They have their volume above 15L, and they can reach up to 40L, with the top of the pot having a diameter between 33cm to 50cm and a height between 30cm and 45cm.

How to create the perfect pot-plant combination

Your plant will benefit from a good pot. Not too big or too small, but always with good drainage. Here you can find the answers to some significant aspects that affect your plants’ growth.

Excess water

Regardless of the pot, it is essential that excess water can flow out of it. So always make sure that the bottom of the pot is pierced with small holes. To avoid flooding your living room, put the plant with the plastic pot pierced with drainage holes in a closed pot. It should always ensure that there’s free space of about one centimetre at the bottom of the pothole so that the pot is not soaked in water. A few pebbles, pieces of cork, or an upturned saucer will do the trick. You might also put the plant in a terracotta or plastic pot with a pierced bottom and rest it on a saucer that will gather the excess water. Watering your plants the right way is the key to keep them healthy!

Terracotta or plastic?

  • The terracotta pots are porous and breathe a little. On the one hand, it means that the water also evaporates through the pot, and therefore the plant needs to be watered more often. On the other hand, this porosity also ensures that air enters the soil. This is important for many plants to keep the roots healthy and fresh. Practical advice! If you have a new pot, start by soaking it in water for a quarter of an hour. The new pots are often so dry and thirsty that they absorb all the water from the first watering without leaving anything for the plant. Give your plants extra plant food to boost their growth and keep them healthy. 
  • The plastic ones have the advantage of being waterproof and therefore retaining the water well. The water from the watering goes directly to the plant and does not get lost in the pot’s walls. The downside is that the roots are only ventilated from the top of the soil.


When selecting a pot, weight should also be considered. If you intend to move the plant often, for example, because it is in a dark place and you have to give it light regularly, a plastic pot is very light. The terracotta pots are heavier, especially the big ones. However, they have the advantage of being more stable.

Perfect shape

Most plants don’t like pots that are too big. Water might accumulate in areas where the roots are unable to reach, causing the plant to rot. But a pot that is too small does not provide the space the plant needs to grow. To find out if the houseplants’ pots are too small, look at the plant’s roots. If they push up or out through the holes at the bottom of the pot, they urgently need space. Sometimes plants need a new pot as soon as they are purchased. Before giving it a definitive location, check to see if your plant doesn’t need a larger pot.

Plants that live in pots for a long time

Some species are made to live sustainably in the narrow space of a pot. It is especially the case of Nadina or sacred bamboo that grows very slowly. It is characterised by its bright scarlet and lush green foliage. Plants that are easily pruned, such as maples, are also ideal for potted cultivation. Others, such as tulips and narcissus, bulbous flowers that do not grow in height, are perfect for garnishing pots in a sustainable and maintenance-free manner.

Easy-to-maintain plants

Not the green hand or just too busy to tackle gardening? Certain plants do not necessitate a lot of attention to live and bloom. This group of easy-going plants is the lovely Amaryllis, recognisable by its large white flowers striped in red. It requires only moderate watering. It is flowering all year round and sporting a bright red. Anthurium also grows without much care. Brightening up the garden with its variegated colours, the beauty at night requires only water and nothing else. The Cosmos, Hydrangea or Hyacinth, and many others are also part of these potted cultivable plants that don’t need your constant attention.

Is it necessary to systematically repot a plant?

A pot is a home for plants or young trees. When you want to create a natural green corner, the inner space’s size and the potting soil offer the plant the conditions to thrive and develop further. A plant needs a pot of its proper size, neither too small nor too large: as it grows, it is necessary to offer successive pots offering its roots the place to flourish.

Why you need to repot a plant

A plant in a pot lives in a limited volume of substrate, which is rapidly depleted. After a while, the plant fades, no longer benefiting from the nutrients the soil has. In general, it is necessary to repot the plants that have just been purchased, as they are often grown in pots a little too small, especially when it comes to indoor plants.

When to repot a plant

Repot your house plants subsequently for a young growing plant; every two or three years after that. The perfect time for transplanting is early spring, with another possible period being late summer. When a plant’s size has become a little bit too much, repotting becomes complicated, even if we are talking about decorative pots. It is then possible to partially replace the substrate without repotting, using a simple surfacing. This technique is particularly recommended to avoid transplanting ficus or other tropical plants of immense dimensions.

Repotting for plant maintenance

This process helps your plants live a longer and healthier life. The maintenance of potted plants requires attention and care that are sometimes difficult to provide. Still, everyone would like to have a green and flourishing outdoor or indoor space. Fortunately, even for those who do not have a green hand, this dream can become a reality. Having a nice floral decoration on the outside is good. But making it last to the fullest is even better. With these easy-to-apply combinations of tricks, you can do it like an expert.

Finding the right pot for your plant is very important! The planter you’ll choose will affect how well and healthy your plant will grow and is important to the overall aesthetics of your house or garden. Now that you have all the information you need, it’s time to make the right choice and secure your plants’ long term health and growth!
