How to protect succulents from the cold: here are the care to be devoted to succulents in winter. Let's talk about succulents grown in the garden or at home.
Starting from the end of September, succulents gradually loosen their vegetative activity, prepare for winter rest and to face the cold. For this reason it will be necessary to adoptcarespecific to allow plants to better cope withwinterwhich is coming. From irrigation to fertilization, here's how to protect succulents from the cold and snow.
Watering succulents in winter, yes or no?
From the end of September it is important to start to thin out the irrigations, in October it will be enough to irrigate the succulents twice (at intervals of 15 days).
Succulents with dry soil tolerate the cold better.
From the end of October irrigation will have to be suspended.
Fertilize succulents in winter, yes or no?
As regards thefertilizations, the last of the year should never go beyond the month of October, maximum in the first half of November.
The last fertilization of the year can be done by adding a potassium sulphate-based fertilizer to the irrigation water. Potassium sulfate is very useful for strengthening tissues and increasing the resistance of succulents to cold. It protects succulent plants from any rot, disease and adverse weather conditions (frost, snow, wind…).
Where to buy potassium sulfate? In garden centers, at agricultural consortia or by taking advantage of online sales. On Amazon, a 1.25 kg pack of potassium sulphate is offered at a price of 19.20 euros with free shipping. It is useful for all plants that fear the cold.
For all information, I refer you to the page: Vitax potassium fertilizer
On the package we read Sulphate of Potash which means precisely Potassium sulfate, do not be fooled by the images, potassium sulfate is widely used in the cultivation of berries but it is perfect for all plants, including succulent.
On the contrary, nitrogen-based fertilizations which lower the cold resistance of plants are absolutely to be avoided. Nitrogen fertilization should be suspended by September.
How to protect succulents from the cold: succulents grown in the open ground
Forprotect succulents from the coldyou have to take action as early as October, when night temperatures (especially in the North) are too low for most offat plants. Thefat plantsresistant to cold they can withstand temperatures around zero or even much below zero degrees, as long as they are sheltered from rain and with low levels of ambient humidity.
When succulents are grown in the garden, in the open ground, it is important to make sure you have very well-draining soil.
Many species of Trichocereus, Opuntia, Cylindropuntia, Gymnocalycium, Echinocereus, Rebutia and Sulcorebutia, come from areas where winters are very cold even if dry. These plants, if kept away from moisture, will have no problem withstanding the cold.
For allfat plantsgrown in the ground, a valid protection from the cold is constituted by the non-woven fabric. Unlike potassium sulphate, which can only be found in well-stocked garden centers, non-woven fabric is everywhere! This material manages to protect against frost without hindering transpiration and photosynthesis.
The non-woven fabric should be put on at the beginning of November, based on the seasonal climatic trend and removed in the following spring. When removing the non-woven fabric, attention must be paid to the spines of succulents: they can become entangled in the fabric and by removing it we risk damaging the plant. Proceed with caution!
Yes they canmulch succulents? Undoubtedly yes, but the mulch must NOT be given by bark, leaves, straw, expanded clay ... these materials tend to retain moisture and can cause rot. If you want to mulch succulents in winter, use black plastic sheeting. The plastic keeps can protect the ground from the cold without retaining moisture.
How to protect succulents from the cold: succulents in pots
The first thing to do forprotect succulents from the coldis to find a shelter: bring thefat plantsin a bright and well-ventilated place, keep dry and with temperatures that do not drop below 5 ° C, especially if it issucculent plantssuch as Discocactus, Euphorbia, Kalanchoe, Matucana, Melocactus and Uebelmannia.
Succulents grown at home should also be irrigated in winter. Watering should occur every 20 - 30 days. Indeed, make sure that the air in the house is not too dry and if the succulents are in air-conditioned rooms, spray the plant with rainwater or distilled water.
Plants resistant to cold, rain and location
Cold-resistant succulents do not need special care. Many succulents can be grown in the garden without too many problems, namely: Trichocereus, Opuntia, Cylindropuntia, Gymnocalycium, Echinocereus, Rebutia, Sulcorebutia ...
Thecold-resistant succulent plantsthey can also bear temperatures close to - 10 ° C, they are species belonging to the generaAgave, Echinopsis, Echinocactus, Gymnocalycium, Mammillaria, Notocactus, Rebutia, Trichocereus... even in this case, however, we must keep thefat plantsprotected from rain and humidity.
To these rules, succulents of tropical origin that cannot stand the cold are an exception: they suffer with temperatures below 13-14 ° C. Who cultivatessucculent plantsof tropical origin of the genera Monadenium, Epiphyllum, Hylocereus, Haworthia and Hoya, it will do well to house them in bright locations. These plants go dormant during the Italian winter. Even the caudiciform species that love heat should be brought indoors in a bright environment, as is the case of the genera Adenium and Pachypodium.
For succulent plants with flowers, such as Ariocarpus, for example, be careful not to wet the flowers because water could penetrate at the level of the vegetative apex through the inflorescence, causing widespread rot.
