Cacti come in a wide range of colors, textures, and sizes for their flowers. Cacti can be divided into two primary categories: desert cacti (which are typically armed with spines) and jungle cacti (often without spines and most are epiphytes). You can have an interesting houseplant that is trouble-free and long-lasting if you choose the proper cactus for the right location.
When to repot
As soon as the roots start to peek through the drainage holes at the bottom of the pot, cacti need to be repotted. Fast-growing plants should typically be repotted every two to three years, whereas slow-growing species should be done so every three to four years. The optimum time to repot cactus is in the spring when they are actively growing. Two days prior to repotting, water the cactus to keep the roots moist but not soggy.
How do you know when to repot your cactus?
If you notice roots protruding from the container’s bottom, it’s time to repot your cactus. This suggests that it is excessively root-bound. The majority of cacti enjoy being in small areas and can remain in their container for many years. You’ll know it has grown too much and needs repotting when you see roots.
Since they prefer it snug, the container in the next larger size will be suitable. Repotting should be done every two to four years as a general rule. The latter is preferable if you fertilize annually, but if you don’t, you should repot after two years to restore soil fertility. The optimal time is in January or February, when there is active growth.
In the winter, can I repot a cactus?
A good gardener should frequently evaluate the plant to determine what it requires for maximum growth even though cacti are often repotted every two to three years. They should also keep in mind the circumstances described above in order to schedule a timely repotting activity.
To reduce heat stress, these plants should ideally be repotted in the spring or early summer when the weather is generally favorable. Never repot a cactus during the winter since the cold will prevent rooted and cause it to perish (2). Additionally, because adult cacti’s root tips are more vulnerable to harm, they should only be replanted when necessary.
Do cacti prefer little pots?
Your cactus or succulent plant’s survival depends on the pot size and soil type you choose.
In this section, you will learn how to pot or repot your plant, how to knock out a plant, and how to manage prickly plants, as well as everything else you need to know about properly caring for your cactus or succulent plant.
When they’re young, succulents and cacti can be kept in a dish garden. For a start, the common clay bonsai trays are excellent.
The plants can be moved into their own pots when they become too large. No matter the temperature—45°F or 85°F—the plants will remain the same size if you keep them dry. The plants will rot if you water them in cold weather or when they are dormant.
Avoid overpoting. Rotting roots are frequently caused by overpotting. Put the smaller pot into the larger pot and fill the area in between with gravel if the plant is top heavy. This will provide the plant with a sturdy foundation without putting it at risk of decay.
Pot Size
Cacti and other succulents should be potted in the smallest containers possible. Use a pot for cactus that is just big enough to accommodate the plant. Use a pot that is just a little bit bigger than the root ball for other succulents.
The drainage provided by the holes on the pot’s bottom is insufficient for some plants. Make the hole in a clay pot bigger by using a hammer and a screwdriver. For a plastic pot, use a hot knife or hot ice pick.
In either scenario, take care to avoid burning yourself or breaking the pot. If the clay pot does crack, save the fragments for your subsequent planting endeavor rather than throwing them away.
Soil
The potting material is less significant than excellent drainage. A thick layer of gravel or crumbled bricks should be put over the porous soil. More humus (organic matter) is preferred by spineless succulents in their potting soil.
We typically use the terms “heavy,” “organic,” and “light” to describe different types of soil. These definitions mean as follows:
Heavy. This is composed of clay, loam, or good garden soil with roughly one-third humus. It should contain roughly one-third washed builder’s sand or perlite where good drainage is necessary.
Organic. This is humus-rich soil, leaf mold (decomposed leaves), or some other organic material-rich soil. The drainage will be improved by using perlite or coarse builder’s sand.
Light. This describes a material with an open texture that has great drainage and can be kept damp but never wet. Plants that spend time in trees in the natural world benefit from it.
How to Pot
1. Choose a pot that is not excessively huge.
2. Fill the bottom with enough drainage material.
3. Insert your potting material into it until it is roughly one-third filled.
4. Check the plant’s size (make sure it won’t be too high above the pot’s top or too far down in the pot). Unless the plant prefers to move horizontally, in which case it should be placed at one edge, place the plant in the middle.
5. Fill all the crevices between the plant and the pot with your potting medium while holding the plant gently where you want it to stay.
6. Shake the pot to help the soil settle, then gently press the earth down around the roots. Add extra soil if there isn’t enough or if it starts to pack down. Older plants get more earth packed around them than seedlings do. So that there is room for water, leave a space between the top of the medium and the top of the pot.
7. Give the plant water.
Repotting
The process is essentially the same when working with plants that are already potted, with the exception that you must start by taking the plant out of pot 1.
Sometimes the plant can be readily removed, but other times it can be more difficult. Do not pull on the plant if it is stubbornly refusing to emerge from the pot. The container breaking can be preferable to the plant being damaged or having its top broken off.
How to Knock Out a Plant
If the plant is stuck in its pot, try gently tapping the pot against something hard, like wood or concrete, to see if you can squirm it out.
If it doesn’t work, try carefully slicing the inside of the pot with a knife to see if the plant will now emerge.
If that doesn’t work and the pot is made of clay, use your hammer to smash it with a few controlled strokes that won’t harm the plant.
Take part of the soil around the root ball out once the plant has been removed from the pot. Prune away a portion of the roots if they appear to be overgrown.
You can take a knife and simply chop off the outside of the root ball, including the roots, on some plants where the roots become extremely, extremely thick. If you wish to retain your plant in the same-sized container, you can also utilize this root pruning technique.
You can keep your plant “growing on” in the same container for years by first cutting some of the roots and then portion of the top.
How to Handle Spiny Plants
Handle prickly plants by wrapping them in a narrow band of newspaper. Using the band like a belt or harness, wrap it around the plant. For each plant, use a new band.
Gloves are uncomfortable to handle because the small spines break off inside the glove and the huge spines stab right through the glove.
Actually rather simple to propagate are cacti and other succulents. Learn everything you need to know about successful plant propagation in the section that follows.
Before repotting my cactus, should I water it?
Today, we’ll talk about another aspect of caring for cacti. In this article, we’ll discuss how to repot or transplant a tiny, tall, or huge cactus and share our insider knowledge and advice. We’ll also go over when to repot your cactus and how to do it safely so you don’t get stabbed or harmed. Then we’ll cover how to take care of cacti after repotting them.
Should I repot my cactus and how often should I do it?
Yes, you must repot new cacti every year and adult plants every two years. Because cacti grow and eventually require additional space and new growing material, repotting or transplanting them is crucial.
Growing cacti will require additional room because their roots will spread out inside the soil mixture. By inspecting the rootball at the pot’s base, you can make sure (which should have drainage holes). You should repot your cactus as soon as possible if any roots are showing.
The same holds true if you remove the cactus from its pot and can see its roots wrapping around the root ball. Repotting also typically “wakes up” your cactus and promotes healthy growth.
What is the best time to repot a cactus?
The conclusion of the dormant season is the ideal time to repot cacti. Your cactus will experience less stress as a result. For many plants, the dormant time will vary. However, the majority of cacti that are found in regions with harsh winters are compelled to hibernate from November until the end of February.
General important tips for repotting cacti:
- Before or after transplanting your cacti, avoid watering them. So that roots can continue to grow, let the soil dry. Additionally, you should hold off on watering your cactus for seven to ten days after repotting. This is crucial since handling the plant could harm the roots, and any contact with water could kill the plant.
- Since certain cacti have extremely pointed spines, additional protection is required when repotting them. This can be a spare glove, newspaper, or piece of cloth.
- When repotting cacti, you must safeguard your hands. Several cactus will have longer, sharper spines, so be extra cautious! These nitrile coated gloves, which function far better than leather gloves since they are thicker, are the ideal tools for defending your hands from spiky cacti. Wear two sets of gloves or get gloves with double coating if you have a cactus with sharp spikes.
How to repot your cactusstep by step overview
- Prepare the materials and the area before you start repotting your cactus. Have ready-mixed soil, a plastic container for handling root balls, a brush, nitrile gloves, a wooden stick, some folded newspaper, and shears with micro-tips or scissors on hand as well.
- Select a container for your cactus. A pot should be larger than the one before it and cleaned and sanitized. Avoid choosing a pot that is too big since cactus want a snug fit. When choosing a pot, make sure it isn’t too deep and that it is at least 1-2 inches wider than your cactus. However, there should be enough room for the roots of the cacti to sit comfortably in the pot. Pick the same-sized container and repot your cactus if it has extremely weak roots and hasn’t been growing steadily. This will encourage growth. Add bone meal, egg shells, or time-release fertilizer to the soil. Read more about selecting a container here.
- Add charcoal and some rocks or gravel to the pot you’ll be using. This will facilitate drainage and stop soil from escaping drainage holes. Add some fresh soil mixture on top before planting your cactus.
- Remove your cactus from the pot (we’ll go over how to do it in a moment) and clean the roots of any old soil. If the old soil is difficult to remove, soak it.
How frequently should a cactus be watered?
The most frequent reason for cacti failure is improper watering, whether it is done too much or too little. Cacti have evolved to store water for extended periods of time and can maintain moisture through droughts because they are endemic to arid regions and dry temperatures. They have a limited capacity, which is why over-watering can result in a variety of issues.
When it comes to regularity, watering your cacti will largely depend on the season but also on the variety. Checking the soil is the easiest technique to determine whether your cactus needs water: It’s time for a drink if the top inch is dry. That entails applying the “soak and dry procedure” on cactus.
What is the soak and dry method?
The soak and dry technique is thoroughly wetting the soil until part of it begins to flow out the drainage hole, then waiting until the mixture is nearly dry before wetting it once more. If done properly, this strategy will help them endure a period of under-watering should you need to travel or leave the house because it takes use of their natural tendency to store water (or if you just get busy and watering falls to the wayside, as happens to all of us now and again).
Watering during the growing season versus the inactive season
Like with many houseplants, the season affects how frequently you need water. It becomes more crucial that you get in the habit of examining the soil to determine whether your cacti are thirsty. A healthy cactus needs watering every one to two weeks during the growing season, according to general wisdom. The frequency changes to once every three to four weeks during the off-season.
Even then, it’s crucial to examine the soil. The same way that not all interior spaces and not all cacti are alike. The only way to be certain that your cactus require watering is to carefully examine the soil to determine how dry it is because there are so many different factors.
How frequently should I water my houseplant cactus?
Only water cacti when the soil in the potting container is almost entirely dry. Saturate the soil and, if you can, stay away from the leaves when watering. When you notice water dripping from the potting vessel’s drainage holes, stop watering.
A cactus plant kept indoors needs watering every 10 days or more during the spring and summer. Cacti only need to be watered every 4 to 6 weeks in the winter.
Typically, underwatered cactus plants will exhibit the following symptoms:
- Deflated, rubbery, and pale leaves
- a color difference on the stems and leaves
- the leaves are fading
- drop-dead leaves
- Dryness on the touch and in appearance
- The pot’s lighter weight
Avoid spraying the leaves and foliage of cacti in general. This frequently causes stagnant water to accumulate on the leaves, which can hasten the spread of fungus infections.
When watering your cactus plants, try to use either rainwater or distilled water. The water that comes out of the tap is frequently overly chlorinated and contains undesirable elements and minerals that can accumulate in the soil.
