5 Amazing Facts You Didn’t Know About Cacti
You may see an indoor cactus as something that is ordinary, plain, and sometimes boring, but if you get to know them better, you will be amazed at what these plants can do.
Cacti Can Store Large Amounts Of Water
Cacti have a shallow root system that enables them to absorb as much water as they can. The roots of these succulents are only 1.3 cm deep; therefore, it doesn’t take long for rainwater to reach them for absorption.
Besides having shallow roots, cacti roots cover large areas. And because they cover larger areas, the roots can absorb more water.
After absorption, the cacti stores water with its stem so it looks swollen. If you want to know if it has rained in the desert, look at a cacti’s turgidity.
Cacti Stomata Open At Night
Cacti have what scientists call a CAM, or crassulacean acid metabolism.
CAM enables these plants to open their stomata at night during cool temperatures.
During the sizzling months of summer, temperatures are unbearable, stressing the plants. The cacti close their stomata both day and night, leading to a resting phase where the plants don’t grow.
Cacti Have Spines Instead of Leaves
Spines are a cacti’s defense. The spiky needles pierce skin upon close contact. Punctures from a spine are extremely painful for desert animals to withstand.
The spines are also tricky to remove from the skin and cause infections. Cacti spines can even cause multiple injuries in one area.
Spines are also helpful in collecting water in foggy deserts. When the mist lands on the spine, it turns into water that trickles down to the ground below. The roots of the cacti then absorb this water for storage.
A Cactus Plant Can Live for Ages
Cacti plants only require minimal care and great longevity as well. There are more than 1500 cacti species. A cactus plant can live between 10 to 200 years.
Cacti Recruit Ants as Bodyguards
The cactus plants produce nectar to attract ants. Since the temperature in deserts is sizzling hot with limited resources to quench hunger and thirst, ants often migrate to a cactus.
How are ants beneficial to a cactus’s life? These ants attack small animals that pass through the spaces on the cactus’s spine. Furthermore, ants attack bacteria and fungi that might otherwise harm the cacti.
5 Need-to-Know Tips for Mastering Indoor Cactus
An indoor cactus may be different from those that you see near the beaches and in deserts. Read on and find out how to master these succulents.
Light, Temperature And Ventilation
Whether you are keeping your cacti indoors or outdoors, you must give them the maximum amount of light possible. If your cacti are planted outdoors, make sure they are in a location that gets sufficient light. For indoor cactus, place them on a windowsill to receive sunlight.
If you keep your cactus indoors, placing it in a shaded spot such as a bookshelf is not recommended since it might not survive for the long term. Although different cacti species have different light exposure needs, in most cases, cacti need bright and direct sunlight. To provide your cactus with adequate light, it is best to place it on a balcony, window sill or any unshaded spot in your property.
It is best to get compost designed for cacti or free-draining compost for best outcomes. A plastic pot can retain more moisture, so water your cacti less if planted in this pot material and ensure the compost doesn’t get too much water.
Watering and Feeding
Every cactus species is different. It is up to you to observe changes in your plants when you water, repot, fertilize, or propagate them. Knowing when to water your cactus is critical to he.
One terrific thing about these plants is they are tolerant of water neglect. But bear in mind that there is a limit to this since too much negligence can cause the leaves or stems to wilt.
Fertilizing indoor cactus plants once a year is a good rule. If you are organized and keep to a schedule, feeding them two to three times yearly in the spring, summer, and fall will meet your cacti’s fertilizer requirements.
Overall, cactus plants will require watering every seven to ten days for optimal growth during the spring and summer seasons. Increase the time between watering schedules during the plant’s hibernation during the winter months.
A cactus must be repotted once the roots start to peek out from the drainage holes at the bottom of the pot. Repotting is best done in the spring when cacti are actively growing. Water the cactus two days prior to repotting, so the roots are moistened but not too wet.
Growth Phases of Indoor Cactus
You may think that an indoor cactus has a slow growth rate. Do not worry as this is normal. Below are growth phases that are essential to the indoor cactus and that require your attention.
The first stage of a cactus’s life cycle involves the growth and transformation of the seed into a seedling. Dormant seeds require optimum conditions to help them grow. They need environmental stimuli such as the right temperature, water availability, and light.
The type of ideal conditions depend on the seed. Hard seed coats must erupt with the water absorption. The stored food in the seed needs to be converted into chemicals that promote the growth of the seedling.
As you continue to care for your cactus, you will observe that it starts to grow but at a slow rate. After six months, you may find that your cactus has not undergone dramatic growth. It may a little bigger than a marble.
Compared to other plants and flowers, this may seem abnormally slow. But in the cactus world, this slow growth is typical.
After 12 months, it is not unusual if your cactus is still no bigger than a marble. But upon achieving this milestone, your cactus must be moved from a propagation tray to an individual pot. Moving them to a larger container enables their growth to continue.
How to Make Cactus Soil for Indoor Plants?
Cacti are not accustomed to rich soils ideal for other plants. Instead, they thrive best in nutrient-poor mediums.
A premade cactus soil ensures that the soil contains everything the cactus needs without much involvement on your part. This soil can be purchased in home and gardening shops. Soil for cactus has the optimum range of inorganic materials as well as a tiny amount of organic material such as peat moss or coco coir.
However, mixing your cactus soil is an easy option. Mix three parts potting soil, coarse sand or gravel, and two parts perlite or pumice. Avoid potting soil containing fertilizers since fertilizer can burn off cacti roots and harm their growth.
How to Choose the Right Pot for Your Cactus?
An indoor cactus requires a special pot for them to grow. You need to factor in numerous things when searching for the right material.
For many cactus lovers, the material of the pot is their priority. There is no good or bad material. It will all depend on your preferences.
But many prefer clay pots since this material drains. The porous feature of clay creates an ideal environment for the indoor cactus. Moreover, because the pot absorbs water, it is easier to estimate the soil’s moisture level.
When clay pots suck in the water, the pot turns dark. Another good reason to opt for clay is they are less expensive than other materials. It is also easy to color coordinate them for visual consistency in your space.
The cactus plant is biologically designed to survive prolonged periods without water. But this peculiar adaptive feature can also work against it when it gets too much water and too frequently. Therefore, when selecting a pot, ensure it has a good drainage system to release the excess water. If it doesn’t, drill holes on the pot prior to using it for your cactus.
The Best Size
You must also check the pot’s size. The ideal size must allow a ¼ inch space between the main body of the cactus and the rim of the pot.
You must also examine the depth. Choosing the wrong depth might hinder your cactus’s growth. The depth will depend on the type of species you are planting. The pot’s depth must be proportional to the natural growing process of your cactus. If your cactus grows tall and large and develops deep roots, you must get a deeper pot to accommodate it. But if the cactus has shallow roots, you can utilize a small pot with a shallower depth.
How to Grow Cactus Plants from Seed
Indoor cactus can be grown through seed planting. Here’s how you do it.
- Step 1. Fill the pot with moistened, free-draining compost. Gently press and level the surface. Sprinkle the cactus seeds over the soil’s surface. Make sure to spread the seeds evenly.
- Step 2. Apply a thin layer of vermiculite or fine grit over the seeds. Cover the compost’s entire surface. Cover the pot with a clear plastic bag to preserve the soil’s moisture and leave the pot in a greenhouse or a sunlit windowsill.
- Step 3. The seeds will develop in a few weeks. Remove the plastic and water the compost once it becomes dry. Make sure to spray the surface of the soil and water regularly to keep it moist.
- Step 4. Once spring comes, your seedlings should be ready for transfer. Utilize a fork or spoon, gently remove each cactus taking care not to touch the spikes.
- Step 5. Partially fill a small pot with gritty compost and embed the cactus seedlings. Utilize tweezers to ensure the seedling does not sit at an angle.
- Step 6. Fill the area around the seedling with compost and water. Add in more compost if necessary and utilize a spoon to arrange the gravel around the seedling. Place the pot in a sunny spot, such as a windowsill.
How to Grow Cactus from Cuttings
If you want to grow it by means of cuttings, here’s how.
- Step 1. Choose a healthy stem at least 10 cm long. With a sharp scissor, cut the stem cleanly. It is best to utilize thongs for your safety for spiky cacti. Afterwards, lay the cuttings on a windowsill and leave them to heal.
- Step 2. Fill the pot with cactus peat, then insert your cuttings. Embed the cutting deep enough to help it stand upright. To promote root growth, it is recommended to dip your cuttings in a hormone powder prior to planting.
- Step 3. Water the pot generously, then place it on a warm windowsill away from direct sunlight. Cover the entire thing with a plastic bag.
- Step 4. Check your cuttings regularly and water them only when the soil is dry. In many cases, a cactus will root within a month, but it may take a more extended period for new growth to show.
How to Propagate Cactus Pups
Cover the pot’s base with 1/3 to ½ soil. After planting the pup, please place it in bright but indirect sunlight to maintain the moisture of the medium. Most cacti will root in four to six weeks, but some varieties can take months.
