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.
What factors determine when to repot a 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.
My cactus can I pot it in the winter?
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.
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.
Prepare Your Tools and Supplies
Depending on the size and degree of spikyness of the plant, specific instruments are needed for cactus transplantation. For instance, towels and/or newspapers may not be required while transplanting smaller cacti, whereas larger cacti may need a complete complement of safety gear.
No of the size, handling cacti is always safer when done with thick, protective gloves.
Remove the Cactus from the Old Pot
If required, loosen the dirt around the pot’s edges with a dull knife or trowel. If necessary, you can use the towel to handle the cactus or wrap it in many layers of newspaper to make it easier to hold. Lay the cactus flat on the surface of your work area after gently wriggling the root ball out of the old pot.
Loosen the Root Ball & Discard the Old Soil
The root ball should be loosened and the old soil should be dumped after the cactus has been removed from its old pot. This can occasionally be a delicate process depending on how root-bound the plant is. Slow down and take care not to uproot too many roots.
Inspect the Roots and Trim if Necessary
It is advisable to inspect the roots for any evidence of pests or illnesses while they are exposed. If necessary, prune back any sick or dead roots and use a fungicide.
Choose the New Pot
For your cactus, pick a clay or terracotta pot if you have a tendency to overwater plants. Cacti can grow in any type of potting container, although unglazed clay pots are better since they can absorb extra moisture from the soil and help limit overwatering. No matter what kind of pot you select, make sure the bottom has a drainage hole.
Plant the Cactus in the New Pot
To ensure that the cactus will be planted at the same depth as its previous container, fill the bottom of the new pot with the cactus soil combination (you may buy cactus soil in stores or make it yourself). Place the cactus in the pot gently using the towel or newspaper and hold it there while you add dirt to the remaining space in the pot.
The newly transplanted cactus needs time to adapt to its new environment, so avoid watering it right immediately. You can resume your regular watering regimen after about a week.
Cacti are resilient and adaptable, and the majority of kinds do well when transplanted as long as they were in good condition before being repotted. Make sure to replant your cactus in the same spot where it was originally located so that it can continue to get the same amount of light and ventilation as it did before it was moved.
Cacti are desert plants, thus to promote new development, they need a lot of sunlight. Most cacti kinds thrive in a sunny windowsill that faces south or west. One of the best ways to promote new growth is to leave your cactus outdoors in full light throughout the summer if you live somewhere with warm summers.
What type of soil is best for cacti?
Contrary to most movie sequences, cactus flourishing on pure sand is not a positive thing. A rocky, nutrient-rich soil kept in a well-draining pot or container is what desert cactus, also known as Opuntia cactus or hairy old man cactus, prefer. Ascertain that nutrients such peat moss, coconut coir, pumice, perlite, or vermiculite enable a suitable balance of the soil’s aeration and drainage qualities.
Avoid using forest goods like wood chips and pieces of pine bark and instead start with a base of regular potting soil. Pumice, a light-weight and porous volcanic rock, should be added in two parts. In the absence of those materials, you can use vermiculite, perlite, NAPA oil dry number 8822, aquatic plant soil, non-soluble cat litter, or chicken grit. This component is essential because it provides adequate aeration and allows water to move through your potting mix fast.
Add some coconut coir lastly. This breaks down gradually, adding structure and aiding in the cactus mix’s ability to retain moisture. In contrast to peat, it is also wettable and does not compact during the wetting process.
Cacti Soil For Jungle Cactus
Both lithophytic and epiphytic cacti are fairly universal in the jungle. In other words, they can grow on rocks or rely on the nearby trees to live.
Such cactus species
The orchid cactus has the unusual capacity to obtain its daily requirements from the air as well as from dead leaves or other detritus left in crevasses and fissures.
Therefore, you’ll require a potting mixture containing oak leaf mold, pumice, coconut coir, peat moss, bat guano, and some orchid bark or fir bark to replicate the jungle cactus’ natural growing environment.
Epiphytic cactus require potting soil that resembles that used for desert cacti. After that, you’ll need to make some adjustments.
- Pumice, 1 part, to lessen soil compaction
- coarse orchid bark in two pieces
Compared to simply adding extra ordinary potting soil to the mix, this provides better aeration properties. But with time, the bark degrades and eventually turns into soil, indicating that it is time for repotting.
These are merely a few good cactus potting soil examples that you can use. Of course, the ideal mixture will vary depending on the sort of cactus you want to cultivate, and you’ll also need to prepare the other two key growth settings, namely water and light.
Making your own cactus soil mix is fun in part because you can experiment to see what works best for your favorite succulent and cactus plants.
Can you plant a portion of cactus that has been chopped off?
A loved cactus plant might quickly lose a portion due to overly active kids, scavenging animals, an accidental bump, or an unplanned incident. You need not worry if it occurs to you because you are not required to discard the chopped piece.
Even if the main plant can still survive if a portion of its stem is lost, it may seem wasteful to toss the broken piece and ignore the rest.
Can you then cut a chunk off of a cactus and plant it? Yes is the clear-cut response. Cuttings can be used to grow a sizable number of cacti species. Hedgehog, prickly pear, and branching columnar cacti like the night-blooming cereus are a few of the common cactus species that are typically reproduced via cuttings.
Don’t discard the broken piece if your cactus accidently breaks off a portion of it. Instead, replant it from seed and let it grow.
Winter sun requirements for cacti
Cacti and succulents are excellent low-maintenance plants that add color to the home even on the gloomiest winter days. They provide aesthetic appeal to any table or windowsill with their unique forms and textures, and with proper care, they’ll last the entire long, cold season.
Cacti and succulents are suitable indoor plants all year round. Plants simply only a little light and sporadic watering during the winter. By the time fall arrives, the majority of cacti and succulents have gone dormant and will no longer grow as the weather and light conditions change.
5 Techniques for Winter Cactus and Succulent Care:
1. Plant your dormant plant in a location where it will flourish to make your cacti or succulents happy. During the winter, succulents require less light and can also tolerate indirect light. Make sure your plant receives at least three to four hours of bright light each day for the best results. Locations are happiest close to windows that face south or east.
2. Sandy, well-drained soil is best for growing succulents. Give your plant the nutrients it requires by using Espoma’s cacti and succulent mix. Make sure containers have drainage holes to allow extra water to drain because succulents can’t tolerate excessively moist soil.
3. Set the thermostat. Few succulents can withstand temperatures that are much colder than 50 to 55 degrees.
4. Succulents require deep watering, although they won’t need as much as they do during active growth. Use little water and only from the top, letting water seep through to the bottom. Keep plants out of water for brief periods of time. Keep water away from the cactus’ body since it can cause decay.
5. Look for vermin. Check your leaves every month for mealy bugs and aphids. If a plant is infected, remove it from the vicinity of other plants and spritz it with a solution of 3 parts rubbing alcohol to 1 part water.
Does the size of the pot matter?
It does, indeed. You’ll observe that succulents are described in precise measurements when purchasing one. The length of the cactus is unaffected by a 4 cactus. In its place, it refers to the size of the plant-appropriate pots.
The size of the pot should allow for the plant to grow naturally as if it were its natural habitat, according to the general rule to remember while selecting the appropriate planter size. Usually, large pots are not necessary for cactus plants. The roots will be confined by a little container, leaving no place for the earth, nevertheless. However, if you select a large container, you’ll probably overwater the plant. Therefore, picking the ideal size for the cacti is quite crucial.
The depth
The pot’s depth is also very important since, if you choose the incorrect depth, it could hinder the cactus’ growth. The type of succulent you are planting will determine the depth. The depth of the pot should correspond to the rate at which your cactus will naturally develop. Get a deep pot for your cactus if it grows tall and has a tendency to have deep roots. If the cactus has shallow roots, a shallow pot can be used with ease.
Keep in mind that one of the main reasons you need to repot is the depth factor. When a plant is young, it often has a tiny root system and needs a small pot to prevent overwatering. You will need to repot it as it grows after a few years to accommodate the expanding roots and avoid the roots becoming tangled in the small container. Checking the drainage holes at the bottom of the pot is the only surefire technique to determine whether you need to repotter. It’s time to repot into a larger pot if there are protruding roots.
Width
There are many cactus species with shallow roots that spread out horizontally. Deep pots are not ideal for growing these kinds of cactus. As a result, always learn as much as you can about the cactus species you’re buying or cultivating.
Such a species’ roots will start to appear on the container’s sides if you put it in a long, narrow pot. After that, it’s time to repot the cactus into a larger container.
The width of the plant is another suggestion to assist you in choosing the proper width for your cactus. Choose a pot that is only 10% broader than the cactus after measuring its width. Choose a pot that is only 4.5 inches wide for a plant that is 4 inches broad.
Is it possible to grow several types of cactus in a single pot?
It is, indeed. You must, however, be aware of how each plant grows before selecting the pot. Although most cacti grow slowly, others can grow really quickly. You might need to repot them soon if you pot these species alongside the ones that grow slowly.
Therefore, choose the species that have comparable traits while picking a pot to grow several cactus species. Give them a big bowl so they are not crammed inside the pot. Be aware that you must pay close attention when caring for multiple cacti in a single pot. Make sure that neither the size of the pot nor the soil’s other characteristics favor any particular species while straining the others.
