Just keep reading if you want to avoid container choosing mistakes.


Size Pot For Growing Spinach

When growing a large plant in a small container, chances are, the plant will tilt over because of the containers incapability of handling the weight and height of its occupant. When the pot is too small, the moisture will dry up quickly, so you’ll be bothered to water more frequently.

So what size pot for growing spinach in a greenhouse? Solar energy, water, and soil may be the basic plant necessity, but the perfect pot is the icing on the cake. Here are the things that you should consider:


#1 Base your pot size on your plant size

It is why planting plants’ step one will always be choosing your seeds. Since your plants are the core of your garden’s existence, it is only right that every step or plan will be based on them.

Spinach is not a huge plant and is relatively small, so choosing a small pot will be the best decision. It would be nice to adjust your container to one size up, just in case.


#2 Leave space for adjustment but not too much

It is always nice to have room for future adjustments as long as you don’t overdo it. There is a saying that everything must be done in moderation, and you should never settle for less. This situation is perfect proof of those.

For example, your plant is approximately 4- inches, and you plan to have a pot in the same size. Wrong! You should go a size higher, the 6- inch pot. Don’t go any higher or lower than that.

A too-large container can be rugged for the plant to occupy fully and may result in overwatering, wheres a too-small container can leave the plant rootbound resulting in a tiny amount of soil that won’t be enough to hold the water.


#3 Take note that root size can affect choosing container size

Depending on your type of spinach, your root size can vary. Surprisingly, roots can affect which container you should buy.

Deep roots that can grow bigger and wider can survive in tall and wide containers while small roots are much better off being placed in shallower containers.

If you’re still unsure, the best way to check for the right size would be inspecting the roots

If everything we’ve just mentioned yet fails, take out the plant and observe the roots. Do they fill out your container? Then go a size up. But, if the ratio of soil to roots is 1:1, you’ve probably got the right piece.

If the soil ratio is higher than the roots, then go for a smaller size.


Why Opt To Container Planting?

Besides understanding what size pot for growing spinach in a greenhouse, you should also note why you should opt for container planting. Here are the reasons why:

Saves space

Container planting saves up space when you have a limited area for a greenhouse garden. Almost any plant can be grown in a container. And growing spinach is one of the more basic approaches when you’re starting to plant in pots.

Most of the plant results depend a lot on the container size. So it is vital to be cautious in looking for the perfect container that can fully accommodate your spinach.


Fresh yield

Planting inside containers is ideal. It allows you to harvest all the fresh, dark, leafy greens before pests can get to them. Growing spinach in a pot will also thwart nematodes and other soil insects and diseases.



More amazingly, if spinach is grown in a container, it’s readily accessible. This means that you can plant them anywhere in no specific area as long as there is light, water, and soil. Therefore making the planting, watering, and harvesting of these more convenient for you.


Final Words

Spinach only takes between 40-45 days to develop fully. And after that, you are free to take out your recipe book and decide what spinach dish to make. But what size pot for growing spinach in a greenhouse would you need?

The importance of containers and being careful in choosing them in gardening may not be mentioned a lot, but it affects the plant’s wellbeing. We hope that you have learned from this article and make lots of tasty, healthy spinach!
