When you start getting into gardening, it can be hard to know how often to water plants. It gets even more complicated when you are using a small pot!
Knowing how and when to water a mini cactus is important because if you don’t water it enough, the soil will dry out, and your plant will die.
The roots can rot if you give it too much water, and the stem might fall over.
This article will help you figure out how often you should water your small cactus so that it has the best chance at living long and healthy!
How Often Do You Water a Mini Cactus
Cacti are usually associated with the desert climate, which means they need little water to grow. However, taking care of small cactus plants is a bit different, as cacti are not your typical plants.
Even though cacti are desert plants that conserve water, thus requiring very little of it themselves, you still need to make sure your mini-cactus gets enough moisture.
Most mini cactus plants will need to be watered every one or two weeks. However, this will depend on where you live and the type of potting soil your cactus is planted in.
If you live somewhere hot and dry with little humidity, such as in a desert environment, it may be necessary to water more frequently than once weekly.
If your home has high humidity levels or you keep your house relatively cool year-round (around 70 degrees Fahrenheit), then watering less often is fine-perhaps every two weeks.
Also, make sure that the cactus soil dries out before each new watering; if not, roots could rot and kill off some cacti plants.
You can tell when it’s time to water again by sticking a finger into the earth around its base. If possible, you want to aim for moist but not soggy soil.
If the cactus plant feels heavy and you can’t tell if it’s moist or dry by touching its roots, then you should avoid watering just yet.
Cacti are usually very hardy plants that survive in extreme conditions such as deserts which means they don’t need much care to thrive!
How Often Do You Water a Mini Cactus in Winter
It can be hard to know when is the best time to water mini cactus plants in some places.
Many people assume that they should never get watered during the winter months because of how cold and dry this season feels.
However, while cacti are desert plants which means they require little water for survival, there may come a point where your plant needs more soil moisture than usual!
Typically speaking, most indoor houseplants will need less water once temperatures drop below 50 degrees Fahrenheit or if you don’t see any growth on their spines after two weeks.
If these conditions apply, then reduce watering times until warmer weather returns.
In most cases, mini-cacti may only need to be watered once every two weeks or so during the winter. You should also make sure their soil dries out completely before you water them again–if not, roots could rot and kill off some cacti plants.
Most cacti go dormant during the winter months, which means they require a period of lower amounts of water.
Remember that just because a houseplant is dormant during cold months doesn’t mean you should stop watering them!
They still need moisture to survive, even if they are dormant.
How Do You Know When a Small Cactus Needs Water
To tell if your small cactus needs water, you will want to test the soil first.
First, dig your finger into the top inch of dirt around the plant. If it is moist or wet, then do not water yet as that means it is already receiving plenty of water.
When the soil feels dry, you can add a little bit of water to it and let it soak in before testing again.
If it still feels dry, you can add a little more water and let it soak in before testing the soil again. Continue this process until the soil feels moist but not wet.
You can also test with a moisture meter to see if it is time for watering as well.
One other thing that you will want to do is weigh down the plant. If it feels heavy, then this means there has been added moisture, and you do not need to water it.
However, if you feel the plant is light, this means there has been a lot of water loss, and it will need to be watered.
It is also essential to know the signs of a dry cactus. If you notice brown spots or wilting, then it is time to water as this means there was no moisture added, and the plant needs some right away.
If your small cactus has yellow leaves, it usually means that it is too cold for them to live, so move them somewhere warmer if possible.
It’s critical to understand how to identify the signs that your little cactus is underwatered or overwatered to ensure you’re watering properly and on time.
What Does an Overwatered Cactus Look Like?
A cactus that has been overwatered can appear wilted and brown, but its leaves may retain some moisture.
Instead of appearing dried out like underwatered plants, overwatered succulent plants will have mushy stems and look soggy with water droplets on their leaves.
This type of damage usually occurs when there is too much water in the plant’s growing medium, which causes root rot or fungal diseases to form.
When you see a cactus with mushy, brown stems and soggy leaves, it is likely suffering from overwatering.
An overwatered cactus will need to be treated with fungicides, but it is best to let the soil dry out before watering again.
Do not give your succulent any water for at least a week. This will help kill off whatever diseases or fungi that might have formed due to overwatering, and it will also allow some time for recovery.
What Does an Underwatered Cactus Look Like?
Underwatering can impede the growth of a cactus, as it may not receive an adequate amount of water to support its development.
The plant can wilt, turn brown or even die if it is left unwatered for long periods.
A healthy cactus has a vibrant green color. An underwatered plant will have withered, brown leaves and stems that look dry and shriveled.
If you notice the soil is dry and it has been a long time since your last watering, do not assume that your cactus will be fine if left alone for another few days or even weeks.
The best course of action is to water your cactus at the first sign of wilting.
If you keep ignoring it, it could die because there might not be enough time for its roots to recover before running out of moisture entirely.
How Long Can a Small Cactus Go Without Water
The majority of desert cacti may withstand up to two years without water. However, this isn’t the case for indoor cacti since the environmental conditions are very different.
Small indoor cactus plants can go up to a month without water. However, it’s best not to let them go for this long as they can dry out and die if left unattended for too long.
Small cacti need water to grow, so make sure you give them a good watering once every week or two.
Although cacti are drought-tolerant plants, they still need to be watered to live.
How Much Water Does a Small Cactus Need
Cacti are typically watered once a week. However, small cacti need less water than larger ones because they have smaller roots, and the soil dries out more quickly.
The amount of water needed to water a cactus will depend on the size of your pot. For example, a small cactus might only need about half an inch of water per week, whereas a larger one may need up to two inches.
You can try pouring some water into the cactus pot and leaving it for a few minutes to soak in.
If the soil is still dry, you will need to water the cactus again.
If it looks like there is too much excess water after a few minutes, just pour out the remaining amount of water and do not give more than twice in one week, or your plant can drown.
How Should You Water an Indoor Mini Cactus
When watering your mini cactus, you should always water from the top down. This will allow the water to flow gently down through all of the soil mix.
You should never pour too much water at once because it can cause root rot or mold growth in your plant’s potting mix. Your indoor cactus plant is most likely small enough that it doesn’t need more than one glass of water every week.
When watering indoor plants like this one, try not to let any excess water sit at the bottom of its container because that is how roots get ruined.
The best time to water is in the morning or evening so that your indoor plant has a chance of drying off before nightfall.
If watering isn’t possible for you during these times, try not to leave it too late at night because this may cause fungus and other bacteria to grow on the moist leaves overnight.
You should always use room temperature water when watering indoor plants so that you don’t shock the plant with cold water.
It is also essential to avoid misting your cactus, as this will create a humid atmosphere that may cause fungal diseases.
Watering a small cactus indoors is relatively simple. Just remember to pay attention to how much water you are adding, as too much can ruin your cactus!
Final Thoughts
Small cacti are a great way to introduce the world of gardening and taking care of plants for kids.
They’re also a lovely addition to your office or home, even if you don’t have much time to spend looking after them, because they can be pretty resilient little things!
To maintain the beauty of your mini cactus and ensure it stays healthy, there’s one thing that is essential: water.
So knowing how to water a mini cactus properly is vital for your cactus to thrive.
