Succulents continue to gain popularity among home gardeners, or they could be just getting started. They are growing in popularity since they are simple to grow and can tolerate neglect. Commercial growers are cultivating the plants in their greenhouse operations because they want a piece of the action. Growing succulent plants in greenhouses is a popular hobby.
Do succulents thrive in a greenhouse environment?
Plants with thick, fleshy stems and leaves, such as cacti and succulents, have evolved to store water in arid areas. They have shown tremendous growth in popularity as indoor plants in recent years. They are for sale everywhere, including the majority of big-box retailers. Aloe plants, jade plants, sempervivum, kalanchoes, agaves, echeverias, snake plants, and Christmas cacti are just a few of the hundreds of kinds that are available. Due to their low watering needs and natural adaptation to dry soils, they are popular due in part to how simple they are to maintain. In actuality, overwatering cacti or succulents is one of the simplest ways to destroy them.
Succulents and cacti are in many respects ideal plants to grow in a greenhouse. The light that a greenhouse provides, which ranges from mild to bright, is ideal for almost all of them. They don’t outgrow their station because many of them tend to stay very little. Additionally, the most are relatively simple to propagate, making it inexpensive to build a sizable display of them. I had received some cuttings from a friend who maintains more than 500 different types of cacti and succulents in her greenhouse. I now have a beautiful collection made entirely of these cuttings, some of which are potted separately and others in mixed cultures.
The majority of cacti and succulents grow in grittier soil because it permits plant roots to dry out quickly while still holding some moisture, as might be expected. Not your typical potting soil, this. To suit your plants, you’ll need to either buy or make such a medium. I’ve discovered that the grit in the cactus/succulent combinations that are sold are generally pretty huge and pricey. Therefore, I prefer to prepare my own blend of around 70% grit measuring about 1/4 (6mm) in diameter, 20%–25% crushed pine bark, and 10%–15% vermiculite or perlite. If desired, you can use peat moss or coconut coir (for a more alkaline mixture) in place of vermiculite or perlite (for a more acidic mix). In any case, the plants will only require watering every two weeks or so thanks to this mixture of chemicals, which drain swiftly while holding onto enough moisture.
Most succulents and cacti do best in large, shallow pots, trays, or dishes. Due to these plants’ present popularity, a wide range of sizes of highly appealing pots are readily accessible. However, some succulents and cacti are better suited to a different type of pot. For instance, the rattail cactus grows best in a hanging basket or a large dish held in the greenhouse high enough for the “tails to hang down. The weight of the tails can occasionally drag the pot over and cause it to fall if you try to grow it in a shallow dish that is set on a shelf. It is definitely not advised to grab the falling plant by its long, extremely prickly tails, as I once did! Although rattail cacti don’t typically bloom, when they do, their vivid pinkish-red flowers create an impressive display.
Succulents and cacti typically don’t require much care, including watering requirements. Only water them when the earth seems completely dry. Use a squeeze bottle or a watering can with a spout that is no wider than about 1/4 (6mm). Avoid soaking the plant’s leaves or crown, as this might lead to rot in some species of plants. Don’t water again until the soil is completely dry when the earth is thoroughly moist. With little amounts of water every time, repress the impulse to drink more frequently. You often end up with a plant with a shallow root system if you water it sparingly, and it could perish if you don’t water it again.
Succulents and cacti don’t require special care when it comes to fertilization. They often only receive a small amount of fertilization in the wild from stray bird or animal droppings. You can infer from this that your greenhouse plants don’t require a lot of fertilizer either. In fact, the majority of experts advise fertilizing them just once a year with an all-purpose, balanced fertilizer that is quite weak—a 10-10-10 or 8-8-8 at around half strength—and for all purposes. Of course, you can use a weak manure tea if you want to seem more genuine (made by submerging a bag of horse manure in a 55-gallon pail of water for a few days). However, even this should only be applied at about half strength. The fact that cacti and succulents require little maintenance is a big factor in why so many people are now growing them in greenhouses and homes.
Winter succulent care
There are various reasons why succulents may suffer throughout the winter, but by heeding some essential tips, you may help your plants survive during these trying times.
Temperature
It’s critical to get your plants ready for winter when the air temperature is forecast to fall below 5 C and a ground frost is possible.
Due to the amount of water held in their leaves and stems, the more delicate succulents may be damaged by a light frost at this temperature, and anything below freezing has the potential to kill them. When water freezes, it expands and can rupture plant cell walls, harming or even killing your plants.
Succulents that are kept in the cold and are exposed to moisture may suffer greatly, but plants that are kept in the cold and are exposed to dry circumstances may have a better chance of surviving.
Fleece
For your plants to survive, especially when temperatures drop below freezing, horticultural fleece is a necessity. Horticultural fleece comes in a variety of categories, from light frost to heavy frost. We employ and market a strong horticultural fleece that was made specifically to provide protection down to -10. By covering your plants with horticultural fleece, you may assist retain the heat emitted from the earth, providing a safe atmosphere for your plants similar to that of a blanket. Utilizing the fleece has the additional benefit of helping to preserve your plants from decaying during this cold, rainy time of year by deflecting excess rain away from them.
By having an open weave, this horticultural fleece is made to still provide light and air movement to the plants.
You can help your plants get ready for the winter by doing certain necessary tasks. During the winter, a wide range of factors can harm succulents.
The best chance of survival will be provided for them, though, by good housekeeping. Remove any dead or dying leaves because they may decay and spread fungus and disease.
Moving your plants
In a greenhouse, porch, or conservatory, you can also transfer your plants indoors. In the event that this is not feasible, there may be dry areas near your residences, such as carports and lean-tos, roof overhangs, or even microclimates in front of glass doors and windows. In addition to being a warmer location, this will aid in keeping the rain off your plants during this rainier time of the year.
Succulents should be raised off the ground on ledges and shelves to avoid ground frost; this is especially important in unheated greenhouses. It is a great approach to winterize plants without using greenhouse energy to elevate and wrap them in fleece on benches.
If you can’t move your plants once they are in the garden, you may also safeguard your outdoor succulents by covering them with some horticultural fleece.
Top dressing
A top dress layer is a great technique to keep leaves and stems from rotting in pots or gardens. 20 to 30 mm of Cornish grit, gravel, or stones will be more than enough. During the winter, holding your plants off and above the soggy soil will assist to keep them dryer as more air can circulate around the plant. Additionally, top dressing can serve as a plant-light reflector.
It’s crucial to make sure your succulents receive as much light as possible over the winter, even if you decide to move them.
Feeding
Since you want your plants to cease growing and run out of food by autumn, feeding them over the winter is not advised. When there is less nourishment available, plants halt growing and develop stronger, more resilient plants that can survive the winter.
How might I construct a basic greenhouse at home?
Wood and glass can be used to create an indoor greenhouse if you are handy with tools or know someone who is; but, if you don’t feel confident in your ability to cut, drill, etc. these materials, we have some simple (really, anyone can do them) DIY small greenhouse options here.
- Try repurposing if you want to create an inexpensive indoor greenhouse garden. For instance, cardboard egg cartons can be used to make a small inside greenhouse. Simply place seeds in each depression, cover with plastic wrap, water, and fill with soil or soilless mix. Here it is—a very basic greenhouse.
- Other easy do-it-yourself projects call for yogurt cups, transparent salad containers, transparent containers for precooked chicken, or essentially any clear plastic food container that can be covered.
- Simple indoor small greenhouses can also be created using clear plastic sheeting or bags. To keep heat and moisture inside the construction, use skewers or twigs as supports, cover with plastic, and then tuck the material in around the bottom of the structure.
- Beyond recycling things you already own, you can build a straightforward DIY tiny greenhouse for less than $10 (thanks to your neighborhood dollar store). A great source to find cheap project materials is the dollar shop. For the roof and walls of this greenhouse project, eight picture frames were used. It only need white duct tape, a hot glue gun, and can be painted white for consistency to put it together.
- Making your indoor greenhouse with storm or small casement windows is similar, but more expensive unless you already have them.
Actually, building a small DIY greenhouse can be as simple or difficult, expensive or inexpensive, as you choose. You could just just go out and get one, but what’s the fun in that?
