Plants in the Cactaceae plant family are succulents. This family contains over 1750 different species. Theophrastus utilized an old Greek word to describe a spiky shrub when he gave it the name "cactus." Dry spells and freezing temperatures are not fatal to succulents. They hold water and need a particular type of soil to grow.
Cacti and succulents are adapted to enduring dry spells.
Succulents have developed a way to use the water they store in their stems and leaves to support life during dry seasons. Additionally, they have extremely unique cuticles that almost waterproof their stems and leaves. They can also photosynthesize even when the moisture content of the leaf is low. Succulents may grow from seeds for a very long time, unlike annual plants which cannot endure prolonged dryness.
All plants have stomata, which are also known as stoma in cacti. These stomata are diurnally open and nocturnally closed. This procedure aids cacti in storing carbon dioxide so they can use it for photosynthesis. It's also known that cacti can go for long periods of time without water.
Additionally, some cacti have altered the structure of their roots to store food and water. When the stem is full, their root systems are intended to take over water storage. They also have thick stems that contain water-storing cells that can collapse. Cuticle, a waxy tissue, covers the stems of cactus. Cacti thrive in arid environments thanks to their waxy coating.
The greatest place to grow succulents is inside, where they can withstand chilly temperatures. They prefer a temperature range of 55 to 80 degrees Fahrenheit. Succulents, however, are susceptible to frost damage if they are put close to a window or in direct sunlight. Succulents should be moved to a warmer location and given minimal watering during frost.
Cacti have developed special adaptations that allow them to survive in deserts and other dry settings. They can store water and endure dry spells thanks to their thick, elastic stems and distinctive inner cell architecture. They may photosynthesize all through the dry season thanks to the water-saving stems. Cacti have adapted successfully to the hardest environments despite their modest growth.
Succulents need to be watered every two days for best results. This procedure enables moisture to be absorbed by the succulent soil and reach the roots. The soil need to be evenly moist but not overly so.
They demand a soil mixture.
The care of your succulents or cactus depends on using the right soil mixture. It gives the plant the nutrition it needs, acts as an anchor, and can stop root rot. It also aids the plant's germination process. Because they are specialized plants, succulents and cacti need a soil mixture made specifically for them.
A combination with an organic base is what you should seek out when selecting the correct soil for your succulent plants. Forest products and compost are also used in this combination. Worm casings are also included in some cactus blends. Another excellent option is perlite, which is lightweight and enhances drainage.
The proper pH level should be present in cactus soil mixture. Peat moss should be avoided since it reduces pH levels and might be challenging to re-wet. Coir is a superior option since it helps hold small amounts of moisture. Additionally, adding some charcoal or lava rocks is a smart move because they stop disease from clinging to the plant.
A cactus soil mixture is simple to make. A combination of organic and inorganic components will be required. The mixture needs to drain well enough. For as long as it's sterile and light, you can also use your usual garden soil. It needs to be well rinsed before use.
Additionally, a soil blend made especially for succulents is available. In comparison to creating your own, the soil mixtures are less expensive and simpler to combine. But it's crucial to keep in mind that succulents require well-draining soil. The retention of too much moisture or water can lead to root rot.
Two parts sand, one part gardening soil, and one part perlite make up the ideal soil mixture for succulents. It has a pH balance and offers succulents optimum drainage. It works well for cactus and cacti that resemble jungle plants. Canadian Sphagnum moss, Reed Sedge Peat, Perlite, and Sand are all used in the mixture.
Most garden centers provide a soil blend designed specifically for succulents. The best soil for succulents is one that is light in color and holds moisture. Pick a mixture that dries gradually and uniformly. Use enough inorganic matter, don't forget. Plants will drown in a soil mixture with too much organic content.
They can endure low temperatures.
If given the correct conditions, cactus can tolerate freezing temperatures thanks to its robust root structure. But not all cactus can survive the entire winter in temperatures below zero. Only -25 degrees Celsius are the lowest temperatures that some creatures can tolerate. The kind of soil, how often it snows, and other environmental factors all affect how sensitive to temperature a plant is. The roots may become damaged by freezing temperatures, which will cause the plant to die.
Most succulents thrive in temperatures between 50 to 80 degrees Fahrenheit, which is ideal for growing. Some types, however, can endure temperatures as low as -40°F. Moreover, because they don't need a lot of heat in the winter, most cacti thrive in semi-extreme temperatures.
If it gets below freezing outside, you can move some succulents indoors because they thrive in protected settings. Many common succulents can withstand frigid winters, downpours, and dry spells in the summer. Sempervivum, Rosularia, Delosperma, and Orostachys are a few of these. Additionally, there are Agave and cactus species that can withstand freezing temperatures. These flowers are perfect for terraces, hanging baskets, and rock gardens. During the colder months, many of these plants develop clusters of star-shaped blooms.
The type of succulent will determine if it can withstand chilly temperatures. Others will suffer significant damage if temperatures fall below 50 degrees Fahrenheit, while some can withstand extremely cold temperatures and frost. Succulents, however, can typically withstand freezing temperatures for brief periods of time. As a result, you can move the plant inside or cover it with a covering if you're worried.
A cactus that is cold-hardy may endure temperatures as low as 10 degrees Celsius. The Eastern prickly pear cactus, which can tolerate temperatures as low as -22 degrees Fahrenheit, is one of the coldest-hardy cacti.
Another succulent that can endure chilly temperatures is the echeveria. This plant, which is indigenous to Mexico and Central America, has big, grey leaves and develops in rosette-like formations. Hybrid plants are less tolerant of frost than native species are. Echeveria comes in a variety of forms, such as Echeveria Lilacina, which has rosettes with crests and blue-grayish leaves.
They hold liquids.
Cacti have created complex water-storage systems in order to endure dry spells. The spines gather water, which the stomata then transmit to the stem. While some of the dew drops fall to the ground after running down the stem, others are absorbed by the roots. All cacti have water-storing tissues, which are located in the stem and foliage. The stems are meaty and stout.
The majority of plants that thrive in situations with plenty of water only use a small percentage of the water they receive for growth. Through leaf transpiration, the remaining amount is lost to the atmosphere. However, each drop of water that cactus receive is carefully managed. They have developed technologies that enable them to gather water from both underground and aerated sources. Their spines also guard them against creatures that might drink the water.
Succulents are able to conserve water during the day and use it at night to stay alive. The plants' stomata, which are tiny mouth-shaped structures on their surface that enable them to store water and release CO2, are the key. Photosynthesis causes them to lose the water they accumulate throughout the day.
Some cacti have specialized roots that store water. They have developed this technique to conserve water, enabling them to endure dry spells. While some cacti store water in their stems, others do so in their roots. Some cactus stems have mucilage cells that serve as a reservoir for water.
A fully-grown cactus's size and rib count will determine how much water it can store. The amount of water a cactus can store increases with size. A large cactus, for instance, may store up to 4,800 pounds of water. A Golden Barrel Cactus can store roughly 20 gallons of water when completely grown.
Cacti can utilise the water they store for a variety of metabolic processes. Additionally crucial to their existence is this. Plants need a complex water management system because of arid regions. To absorb water, these plants use trichomes and mucilage. Although the cacti's water collection system is well recognized, little is known about how they absorb and store water.
