Growing barrel cactus from seed is simple. Commercial cactus mix should be poured into a flat before seeds are planted on the soil’s surface. After uniformly misting the soil, sprinkle a light coating of sand on top of the seeds. Keep the flat in a warm area and cover it with a lid or plastic wrap. The seeds easily sprout, and if they are big enough, they may be moved to a bigger container. When handling barrel cacti, always wear gloves since their spines can be uncomfortable.
What is the time required to cultivate a barrel cactus from seed?
The Golden Barrel Cactus, also known as Echinocactus grusonii, normally grows to a height of 36 inches (90 cm), with a diameter of 12 to 24 inches (30 to 60 cm). It starts out developing very quickly before abruptly slowing down. The cactus will therefore take roughly ten years to grow to a diameter of 10 inches (25 cm). Its barrel-like form gives it its common name.
Golden Barrel Cactus seeds can be planted outdoors in warm climates, although indoor planting is simpler and more likely to produce germination. In one to two months, the seeds should begin to sprout.
How can a barrel cactus be grown from seed?
- 1. Purchase seeds: You can either buy seeds from a garden supply store or take some from the barrel cactus flowers on top of the plant.
- 2. Soak: Leave the seeds to soak in water all night.
- 3. Plant: After the seeds have been soaked, plant them in cactus soil in a broad, shallow container or a seed tray. Add a thin layer of dirt over the seeds. For several weeks, keep the container in direct, bright sunshine.
- 4. Water: Maintain soil moisture while seeds are germination.
- 5.Repot: Take the seeds out of their container after they start to sprout, usually after five or six weeks, and plant them in a pot with good drainage. Be patient; barrel cacti might take years to become established.
How are seeds for a golden barrel germination?
The Golden Barrel Cactus is one of the most striking desert plants. Its spherical form, deep ribs, and wavy golden spines appear to sparkle in the sunlight. This is a unique specimen.
Central Mexico is the natural home of echinocactus. They are endangered in the wild even though they are quite popular for cultivation. Finding seed is getting harder and harder.
Easy to grow both inside and outdoors, barrel cacti require ample sun, soil that drains quickly, and few deep waterings during the summer. They can withstand periods of intense heat and drought and can withstand frost up to 30° F. They thrive in a pot in a sunny window in cool areas. The plants grow to be 3′ tall and wide at a very sluggish rate.
It is simple for seeds to sprout. Keep the seeds warm and moist (a sheet of glass or clear plastic helps) in bright, filtered light while surface sowing them in a grittier soil mixture. They’ll start to grow after 4 to 6 weeks. These seeds are true to type and come from a botanical garden.
The Golden Barrel Cactus grows how quickly?
The barrel cactus thrives best in gardens with rockeries, desert-themed landscapes, patios, and botanical gardens.
They are raised indoors in greenhouses or other glass rooms with adequate sunshine. They do appear to have significant difficulties blooming inside, though.
The globular stem can reach heights of 60 inches and widths of 36 inches in the wild or in environments that closely resemble its native habitat in Mexico. A spineless kind of this cactus also features ribbed stems that generate sharp yellowish spines. The cactus’ crown contains woolly hairs that are white in colour at the top.
Mid-summer, the golden barrel cactus will bloom with yellow flowers, though it’s unlikely that they’ll show up indoors. For the desert-like appearance that appeals to cactus gardeners and collectors, these are grown mostly for their foliage rather than their flowers.
Growing and maintenance: The Echinocactus grusonii grows initially pretty quickly before abruptly slowing. The cactus will therefore take roughly 10 years to grow to a diameter of 10 inches. They are drought-tolerant like the majority of cacti and require very little care and attention to thrive. Overwatering and insufficient sunshine are common errors. It is best to use gloves when handling to protect your hands from the thorny spines.
How is a golden barrel reproduced?
Usually, the golden barrel cactus is spread from seed. When planting cactus seeds, place them shallowly in cactus mix and keep them warm and just barely damp. Summertime is when mature cacti bloom, with whorls of blooms erupting from the top of the plant.
Can cactus be grown from seeds easily?
Some people are interested in learning how to cultivate cacti from seed due to the rising popularity of succulent plants and cacti. Anything that produces seeds can be propagated from them, albeit not all seeds are capable of doing so. If the conditions are ideal, cactus seed growth might proceed without your assistance, but this is uncommon. It may take many years for certain seeds to germinate once they fall in their natural environment. You might have to initiate the procedure yourself to get them going. More cactus plants are produced when cactus seeds germinate successfully, increasing your collection.
How frequently do I need to water cactus seeds?
Everything is based on how big your cactus seedlings are. It’s pretty simple to get them to germinate, but the most difficult part is getting them to grow from a seedling into a mature cactus.
If you water your plants excessively, you run the danger of giving them fungus illnesses and other issues that cactus seedlings are particularly vulnerable to. However, if you don’t water the seedlings enough, the tiny, fragile root hairs that are developing on them may dry up and you may lose the seedlings.
<1cm in Width: Keep Soil Moist at All Times
Because they lack the water storage capacity of larger, mature cacti, you must make sure that the soil is always moist when your seedlings are very small, less than 1 centimetre in their breadth. A large, mature cactus may go without water for many, many months. Cactus seedlings can’t do that.
Therefore, at this size, the soil must always be damp but not wet.
There is a distinction between wet soil and damp soil.
>1cm in Width: Water Once a Month
But once they pass that tiny stage—generally when they are one centimetre wide or larger—I start to hold off on watering a little bit longer. I usually only water older cactus once a month and wait until the earth is absolutely dry before I water them again.
A Golden Barrel Cactus can it survive inside?
Some of the most well-liked cacti for indoor growth are barrel cacti. They require little maintenance, and its globe shape, complete with recognisable vertical ribs, gives any space a sculptural, designer feel. Native to Mexico’s scrublands, barrel cactus. They thrive indoors beside a sunny window or, in the summer, outside on a deck, patio, or balcony in an area shielded from the midday light. Slow-growing barrel cactus do not flower until they are fully grown (which could be ten years or more).
Basic Care Summary
thrives on soil that is light and well-drained. In between thorough waterings, let the soil dry out. Never leave a pot sitting in a saucer of water; after watering, dump the saucer of any extra water. During the winter, when plant development slows, use less water. When there is vigorous growth, use a balanced liquid fertiliser every month. If grown outside in the summer, avoid the intense midday sun by placing the plants in bright, indirect sunlight. When handling, put on protective gloves because the spines’ sharp points can cut people and be challenging to remove.
Planting Instructions
For cacti and succulents, start with a high-quality, commercial potting soil. This will guarantee that the soil is clean and free of pests. Many come with a mild starter fertiliser already mixed in. Sand and all-purpose potting soil should be combined in equal amounts if you decide to make your own soil mix.
Choose a container with a drainage hole or be ready to drill one if there isn’t one already.
Fill the planter with potting soil until it is 2 (5 cm) from the rim to prepare it. Create a hole in the soil’s middle that is big enough to accommodate the plant’s root ball.
Wear gloves if the plant has sharp spines to protect your hands. If you’re handling small-spined plants, rubber gloves should be acceptable, but leather gloves give additional protection if the plant has long or sharp needles.
Kitchen tongs can be used to move small plants safely. Wrapping the plant with paper towel or tissue paper is a useful technique for transferring larger plants. For added protection, cover plants that are particularly big or spiky with a layer of newspaper or wrapping paper. Not too tightly, just softly, to avoid crushing the spines. To keep it tightly closed, tape the paper’s outer layer shut many times. The wrappings can be carefully removed once the plant is secured in its new pot.
Take the plant out of the pot. After setting it in the planting hole, cover the root ball with soil, pressing the soil down firmly around the roots. When working with spiky plants, keep your hands away from the spines by using a stick, spatula, or other tool to move the soil.
Every two years, repot. The same container can be utilised if the roots are not pot-bound. If a larger pot is required, pick one that is no more than 1-2 (3-5cm) in diameter larger than the current pot.
Watering Instructions
If at all possible, provide water at the soil level to prevent wetting the plant. Until water is dripping from the pot’s base, irrigate the entire soil surface. This suggests that the ground is very damp. Any extra water that has gathered in the pot’s saucer should be discarded.
Once the top 1-2 (3-5 cm) of the soil is fully dry, do not water it again. Use your finger to feel the soil’s moisture level. During the winter, when the plant grows more slowly due to decreasing light levels, less water may be needed. Even during the winter, some species may fall dormant for a few months.
Fertilizing Instructions
There are many different types of fertilisers, including granulated, slow-release, liquid feeds, organic, and synthetic. Choose a product with a nutritional balance intended for cactus and succulent plants and decide which application technique is most appropriate for the circumstance.
It’s crucial to follow the instructions on the fertiliser box to decide how much and how frequently to feed plants because too much fertiliser can harm plants.
For container plants, slow-release fertilisers are an excellent, hassle-free option. Frequently, plants can receive the ideal level of nourishment for the entire season with just one application.
Cacti or succulents can be fed using a general-purpose fertiliser for home plants, but it must be diluted to 1/4 the strength of the typical rate.
Pruning Instructions
You can trim cactus and succulent plants to get rid of any dead or damaged sections or to keep them a certain size or form. Pruning promotes branching, new growth, and the production of plant fragments that can be used to generate further plants. Maintaining the plant’s shape also promotes additional side shoots and lessens the need for it to establish a deeper root system. Given that the roots are in a small area, this is significant.
Long succulent leaves can be pruned back to the plant’s base depending on how the plant grows. Cut side stems back to the main trunk if necessary. Cut off smaller pieces right above a junction when trimming to shape.
On the primary plant, young cacti are called as “pups. On some cacti varieties, they can grow to be rather thick. With a sharp knife and a 45-degree angle, pups can be removed. The cut region on the pups should be let to air dry until a callus forms so they may be placed in wet sand where they can take root and eventually grow into new plants.
Some succulents and cacti produce “offsets. These are the plants that sprout from short rhizomes and grow near to the mother plant. Similar to pups, these can be removed at the rhizome and utilised to establish new plants.
How are cactus seeds planted?
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 colour.
- A globe-shaped cactus with brilliant pink, funnel-shaped blossoms is called Mammillaria spinosissima. It has reddish-brown or yellow centre 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 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.
