Do you secretly yearn to live in the desert? Plant a cactus to begin your path toward your dream. In regions where they can withstand freezing temperatures, these low-maintenance plants make beautiful landscape plants as well as ideal houseplants. You did read that correctly, There are a ton of cold-tolerant cactus species! For instance, prickly pear cacti may survive rather far north. Giving a cactus what it wants in terms of light, soil, water, and food can ensure its success in any location.
Where to Grow a Cactus
Cactus plants come in a wide variety, some of which even grow in trees! However, the majority of individuals either grow theirs inside as houseplants or outdoors in the landscape. Always read the plant tags for precise information, but in general, cacti want full light and soil that drains quickly. This calls for growing close to a window that faces south or west indoors.
When the nighttime temperature is at least 65 degrees F throughout the summer, you can bring indoor cactus plants outside. Move them to an area with more sun after they have spent some time outside in a protected area getting accustomed to it. If you intend to transport plants between indoors and outdoors, morning sun is optimal.
When to Plant a Cactus
Try to put a cactus outside in the late spring or early summer while the plants are actively growing. They’ll start off more smoothly and swiftly put down roots.
How to Plant a Cactus Outside
1. Most cactus plants require light, permeable soil. Mix native soil and Miracle-Gro Garden Soil for Cactus, Palm & Citrus in equal parts to prepare the soil in the planting location. The cactus is protected by Moisture Control technology against both over- and under-watering, both of which can be problematic.
2. Create a hole that is 11/2 times as big and as deep as the stem or root ball of the plant (some transplanted cacti don’t have large root balls).
3. Position the plant in the hole so that its north side faces that direction. If there isn’t a flag or chalk marking this side, make sure to inquire before you leave the garden center. Here’s why it’s significant: The more sun-exposed south side of the plant typically produces tougher skin that is more resistant to sunburn. On the other hand, the north side might not be able to withstand the sun as well.
4. Add more soil mixture to the area around the root ball and gently pat it down.
5. Lightly water.
6. To acclimate a cactus to the intense outdoor sun before planting one that was produced in an outdoor greenhouse, cover it with a little amount of shade cloth for a few weeks.
How to Plant a Cactus Indoors
1. Choose a container that is 112 times as broad as the stem or root ball of the cactus. You might want to use an unglazed container because it will dry out more rapidly if your environment is humid or you have a tendency to water plants excessively.
2. Add fast-draining to the pot until it is 1/3 full. The perfect nutrients are included in Miracle-Gro Cactus, Palm & Citrus Potting Mix to give your cactus a head start.
3. Set the cactus in the pot with the stem or root ball at the same depth as it was before being moved. To protect your hands, put on gloves or cover them with many layers of newspaper.
4. Fill in the area around the rootball, leaving a space of about an inch between the soil’s top and the container’s rim.
5. Lightly water the soil until it resembles a wrung-out sponge.
How to Water a Cactus
It may come as no surprise to find that under-watering is the second most prevalent reason for cactus plant deaths, even though over-watering is the most common cause. Finding the sweet spot can be challenging because it differs in the summer when plants are actively developing from the winter when they are more passive. A decent rule of thumb is to water your cactus when the top 3 inches of soil are dry if you’re growing it indoors. This might imply a few times every week during the summer and just once every four to six weeks throughout the winter. Watch your plants; if they begin to seem a little withered, they most likely need water. However, unless there hasn’t been any rain in your region for several months, you shouldn’t need to water your cactus at all outside.
How to Feed a Cactus
Cacti may not require a lot of water, but they do require food. If you used Miracle-Gro Garden Soil for Cactus, Palm & Citrus to prepare the soil before planting your cactus outdoors, you should begin feeding it Miracle-Gro Water Soluble All Purpose Plant Food a month after planting. This will provide your prickly baby quick nutrients. Meals should start for potted cactus plants approximately a month after planting. Apply Miracle-Gro Succulent Plant Food directly to the soil, then water as usual to feed your succulent plants. Make sure you read the instructions before using any type of plant food.
How to Prune a Cactus
Put simply, don’t! If you do, all you’ll get is a cut-site area of corky, dried-out scar tissue. The best course of action if your cactus outgrows your living space is to give it to a friend who has more room and get a new, smaller specimen for yourself.
Dealing with Cactus Problems
If you don’t submerge your cactus, it should continue to thrive with little trouble. Unfortunately, there isn’t much you can do to prevent rot problems caused by overwatering besides starting over.
How often 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 can a cactus be grown indoors?
As long as they are placed in an area that receives at least 4 to 6 hours of sunshine every day, cacti can be cultivated indoors. To ensure they are etiolated, we advise rotating them daily in your brightest windowsill, which is typically a southeast-facing window.
How should a cactus be cared for?
Give them a drink, but not too much, and take long intermissions. “Because they store water in their stems, cacti are famed for surviving with little to no watering. That doesn’t imply they don’t require any watering, either. Make sure to inspect the soil periodically. It’s time to water the plant if the top two to three inches of soil are dry “says Palomares.
Thon reiterates Palomares’ counsel and adds: “The temptation to over-water cactus can cause root rot and scab, which manifests as rusty-colored, corky regions on the stems, which is why most people fail at growing cacti. My recommendation is to under-water; you can typically bring them back from the dehydration stage without any problems.”
How do you begin raising cacti?
To thrive, cacti need a sunny location in a compost that is very well-drained, like cactus compost.
Select a windowsill facing south or east for the greatest effects. If the windowsill gets too chilly in the winter, you might need to find them another position.
How to plant cacti
Plant cactus carefully at all times. Your skin may sting and bleed from the spines. To avoid harming yourself while planting your cactus, it is a good idea to use everyday kitchen tools like a fork, spoon, and thick tea towel.
Cactus should be planted in a compost that drains very well, such as cactus compost. Alternately, use a multipurpose compost devoid of peat that has been enriched with horticultural grit or vermiculite to improve drainage.
To finish the aesthetic of the pot display, add a layer of horticultural grit or pebbles. Additionally, this stops water from re-splashing on the cactus.
In our No Fuss video guide, Kevin Smith of Gardeners’ World Magazine demonstrates how to use cactus plants to make a visually appealing display. Kevin discusses how to make a decorative mulch, which compost to use, and why salad tongs are the best tool for handling cacti:
Caring for cactus plants
Water cacti in the summer only once a week at most. A decent watering less frequently is preferable to a little-and-often strategy. In the coldest months, you shouldn’t need to water cacti at all.
Cacti should be repotted every two years to receive fresh compost; larger pots aren’t always necessary.
Stan Griffin of Craig House Cacti shares his three best growing advice for cactus plants in this Golden Rules video, including when to water, feed, and when not to. He also offers guidance on how to take cactus cuttings.
Growing cactus plants: problem solving
Cactus plants often pose no problems. Overwatering or inadequate lighting might cause them to decay at the base. The plants frequently die as a result of this.
Spindly growth is possible in cactus plants, although it is simple to fix. In our Quick Tips video, Emma Crawforth from BBC Gardeners’ World Magazine explains everything.
Cactus varieties to grow
- Golden barrel cactus, Echinocactus grusonii, is initially globular but later becomes tall. It has brilliant green stems with spiky ribs that are native to Mexico. In the summer, flowers that are bright yellow bloom.
- The varied cactus Gymnocalycium paraguayense has flattened spines. In spring and summer, it blooms a creamy white color.
- A globe-shaped cactus with brilliant pink, funnel-shaped blossoms is called Mammillaria spinosissima. It has reddish-brown or yellow center spines.
- Rebutia krainziana is a clump-forming barrel cactus that grows little, white areoles and spines in contrast to its dark green, up to 7 cm in diameter stems. Large, yellow or red flowers grow in a dense clump around the main stem in late spring.
You Will Need
- Cacique seed
- clay and plastic miniature pots
- Cactus compost or free-draining compost
- fine grit or vermiculite
- glass sheet
- spoon or fork
- Tweezers
- Gravel
Step 1
A pot should be filled with a loose-draining, moist compost. Firm the surface down gently and level it. Spread your mixture of cactus seeds evenly around the area, being careful not to sow them too densely.
Step 2
Over the seeds, evenly cover the surface of the compost with a thin layer of vermiculite or fine grit. To keep the soil moist, leave the pot wrapped in a clear plastic bag in a greenhouse or on a warm windowsill.
Step 4
Your seedlings should be ready for transplantation the following spring. To gently pry out individual cactus, use a fork or spoon, being careful not to get the spines on your skin.
Step 6
Add compost all around the seedling and give it plenty of water. If more compost is required, add it after placing the gravel around the seedling with the spoon. Keep in a bright area, like a windowsill, and turn on the pot as necessary.
Do I need to water my cactus?
The watering needs of cacti and succulents varies slightly from those of other plants.
Succulents and cacti don’t need as much water to survive as other types of houseplants because they resemble desert plants.
That does not imply that you should skip watering dried-out succulents. But many individuals question if misting succulent and cactus plants occasionally is appropriate.
Succulents and cacti shouldn’t be misted when being watered because it can weaken the roots and promote fungus. Do not shower succulents and cacti with a spray bottle. Spray misting is not only insufficient in terms of water supply; it also runs the risk of making the plants rot.
While it is not advised to spray these plants, there are a few circumstances in which you should sprinkle cacti and succulents.
