Spider plants are one of the few happy-go-lucky plants in your home, but they do have a unique ability to tell you when they’re ready to be repotted. This brief guide will tell you some insider secrets on how to repot spider plants.

Repoting A Spider Plant

The rules for repotting spider plant variants all depend on visible signs that you can see without too much effort. You will start to see that the overall size of your spider plant takes up only so much that the root system allows it to expand.

Just like a goldfish, a larger tank will stimulate how much a goldfish are encouraged to increase in size. But this can also be controlled to some degree by restricting that growth to some degree.

How to repot a spider plant? Gently remove your spider plant from its current container and brush away the old soil and trim the roots as needed. Fill your new pot up about 1/4 with potting soil and then sit your plant down into the container. Fill in around the sides of the new container and top it off as needed.

Make sure the new pot has drainage holes and that you chose a potting soil that drains well.

Now, this method for stunting the growth isn’t recommended unless you have a small apartment or limited space for growing spider plants. It’s not going to hurt the feelings of your plant in any respect but isn’t a great idea for providing water to a root system that will otherwise become clogged and restricted.

Ultimately, a bigger pot is what a spider plant is going to enjoy so the roots aren’t closed within a limited living space.

Spider Plant Repoting Tips

Wait for the roots to be big enough

The easiest way to check on the progress of your roots is to look for signs that roots are emerging from the water vents. You may even start to see visible roots poking out of the topsoil when you’re watering your plants.

The most obvious giveaway is going to be waiting a couple of days in between watering and then sliding the packed soil out of your pot. You’ll immediately see roots forming on the outside edges of your pot up and down the interior.

If you see a majority of these roots forming along the lower portion of the pot, then it’s time to repot your spider plant right away.

Start looking for the appropriately sited pot that gives you at least one finger space on each side of the pot. This way, the roots will have more than enough room to expand outward as it grows into its new potted home.

When its necessary to repot a Spider Plant

When should you repot a spider plant? You should repot a spider plant when its roots are coming out of the drainage holes, your plant’s soil is drying too quickly or the spider plant’s current container has become damaged. In addition, you may want to repot your plant to prevent it from getting root-bound.

There are optimal times of the year when you need to replant.

When spring comes around you should be on the lookout for indicators that are giving you more than enough reason to replant this decorative species.

How do you know when to repot a spider plant? The best time to repot a spider plant is in the early spring, just before your spider plant is typically enjoying new growth. Repotting isn’t advised in the winter because your plant has already adjusted to cooler temperatures and will survive just fine until spring.

Some signs tell you something is wrong if you see drooping fronds. Due to the type of pot, it’s planted in, it might need better air circulation for the roots.

For pots that hold water and moisture, drooping leaves are a sign that there’s too much moisture in the soil. You’ll be better off repotting spider plant groups to reduce this moisture when others are also in danger. After this, their leaves will start to spring back right away.

Signs Its Time To Repot A Spider Plant

The most obvious sign is seeing roots that are starting to creep out of the drainage holes. It’s also a good idea to repot when roots start showing above the soil that your spider plant is living in.

With more roots, this means that the soil will tend to dry out faster. This leads to droopy leaves that are an instant sign to get a bigger pot. There are instances where a cracked or leaky pot will allow water to escape faster, leading to an eventual transfer too.

Choosing A Spider Plant Pot

Spider Plant Pot Size

What size pot for my spider plant? Choose a spot that is approximately 2 inches larger than the pot you are currently using for your spider plant. This will give the roots of your spider plant room to grow without leaving too much unused potting mix.

You might think that the material pots are made from is the main concern when giving your spider plant an ideal place to live. The reality of this is going to come down to the actual pot size according to the size of your spider plant. This is all about proportion rather than the function of your pot.

The rule of thumb is to choose a pot that is relying on the overall size of your spider plant’s roots. This space is required to let spider plants feel comfortable and have room to expand.

Choose a pot that is slightly larger than the edges of the outer roots. To get extra technical, you should have at least 2-inches of space to buffer your spider plant’s roots.

This is why it’s easy to transfer a growing plant to a larger pot using a gradual variety of pot sizes. After this, it’s only a matter of preference which material you replant them in. There are always going to be special considerations on materials to allow excess water to drain and vent.

Spider Plant Pot Type

What kind of pot do spider plants like? Plastic pots with adequate drainage holes are the best pots for spider plants. This is because plastic pots make the best hangers and because they do not absorb any water, taking it away from the roots. In addition, plastic pots are lightweight making it easy to move your plant.

Plastic pots are also one of the most affordable pots available.

Spider Plant Root Growth

Do spider plants like to be pot-bound? Spider plants like to be somewhat pot-bound, that’s why you only increase the container size a few inches at a time. However, they do not like to be root bound to the point that it begins to limit the growth and development of the plant.

Spider plants are very happy when they have all the benefits they enjoy including water, moderate sunlight, and occasional soil nutrients. To be honest, spider plants will enjoy living in a pot, in a planter, and planted in groups with others.

As long as the amount of space these plants share isn’t conflicting with their root system, repotting spider plant variants will enjoy being potted with others in their neighborhood.

If that’s the case, you’ll need to have a large enough pot to space their roots apart from each other so they aren’t affected by malnutrition in any way.

This is what can cause your spider plant more problems, and will show immediately with the outside appearance. Just like any plant needs, if the size of your pot is limited, your spider plant will start searching for space outside their pot as a result.

What kind of soil to use for a spider plant? Spider plants prefer soil that can drain well while retaining moisture. In addition, spider plants like soil that is slightly acidic. A mix containing coconut coir, peat moss, mulch, or bark would work well for spider plants.

Spider plants don’t need extra attention to what’s in their soil so all-purpose potting soil is perfectly fine for them. They won’t do great if this soil gets too wet if there’s no venting for allowing excess water to drain.

Changing the soil will allow excessively moist soil to disperse better and keep your spider plant roots from rotting. This usually happens when organisms and mold start to form in the soil and start to attack spider plant roots.

You can add perlite or pumice that help the soil stay better aerated and also add nutritional additives into the soil including plant food, worm castings, and other nutrient-rich ingredients for potting soil.

All of these combined items will give the spider plant root system what it needs to feed and stay healthy. As long as excess water is allowed to drain, pots that don’t vent water will cause your plant to become sickened as a result.

Frequently Asked Questions

How big of a pot does a spider plant need?

Start a new spider plant in a pot that is 4 to 6 inches in diameter. You want to give the new plant enough room to grow, however, you do not want to leave a lot of unused potting soil in the container. The soil will leach water and potentially create an area for pests or mold.

What happens if you leave spider plant babies?

As helpful as spider babies will be for purifying the air in your home, too many of them can put a lot of stress on your spider plant. What happens is that these babies will require just as much water as your mother plant needs. These little offshoots are essentially parasites to the rest of your spider plant. These spiderlings will suck up all the nutrients and water that would otherwise go to your entire spider plant.

Should I cut the babies off my spider plant?

One of the cool aspects of spider plants is spotting new little spider baby growths that form on the ends of your shoots. If there are one or two, these are cute and attractive looking, but if there are more of them you will need to make a decision. Whether you make the call to cut them off, the best method is to cut these shoots off as close to the base where sprout from. After this, they can be transferred to the soil so their roots will immediately start to grow.


In conclusion, repoting your spider plant is not as hard or complicated as it may seem. Just choose a pot that is about 2 inches larger than the pot you are currently using.

Make sure it has ample drainage holes and is light enough so that you can move it around to get optimal lighting for your plant at any time of the year.

Then fill it with a quality potting mix that drains well but can still retain moisture. If you can do all of that then your spider plant will thrive!
