Features of caring for indoor palm trees in winter
In the cultivation of indoor palm trees there is nothing complicated, but only if you carefully study the characteristics of the selected plant. One of the most important points for any indoor palm tree is wintering. They can still adapt to the conditions of home keeping palms from spring to autumn, but wintering with poor lighting and heating systems can be a real challenge for these legendary plants. To help palm trees survive the winter, it is necessary to correctly and in time adjust both lighting, and temperature, and care.
The most popular of the large indoor plants - palm trees - are special not only externally, but also in nature. Despite the fact that they are inferior to their natural counterparts several dozen times in size, palms do not change their habits in rooms. They not only create a vibrant tropical atmosphere around them and transform the interiors, but also require the reconstruction of their usual microclimate.
All palm trees, without exception, belong to cultures that require a strict selection of conditions of detention and scrupulous care - carefully following the rules of cultivation recommended for them.
Different palm trees - different wintering temperatures
Depending on the origin - subtropical or tropical - not only the possibilities of choosing a comfortable place during the period of active growth change, but also which palms need wintering. Subtropical palm trees require coolness, moderate temperatures, tropical winters in warm or moderately warm conditions.
Among the palm trees that are all year long prefer stable temperatures and do not tolerate cold snap below 15-18 degrees, even for a short time, belong to yellowish dipisis, coconut, livistona rotundifolia, geonom, ropostalis. And Howster Forster, areca catechu, lithocarium, Weddel’s microcelium, patching lontaroid, lycala, acanthophenix, date Robelini, eaterpa edible and karyota are mild and generally like to winter at a temperature of at least 18 degrees.
In moderate heat, at a temperature of 10 to 15 degrees, such types of indoor palm trees as elegant chamedorea, sabal, brachea prefer to winter.
But Washington is nitenous, squat chamerops, Canarian dates, Fortune trachicarpus and high rapis can even winter at a temperature below 10 degrees (but not lower than 3-4 degrees of heat, the optimal value is from 5 to 8 degrees).
Palm trees are one of the most sensitive plants to soil temperature. It is worthwhile to make sure that the risk of uneven cooling of the substrate, instability of the temperature of the root coma is minimized. Tanks should not consist on cold surfaces (even if palm trees are grown in wooden tubs).
For the winter, outdoor plants are installed on substrates or stands (if the house has underfloor heating, this measure will protect against root overheating), and plants on window sills are removed from the glass or removed from the window on the stands.
If the room temperature constantly fluctuates, it is worth considering additional protection of the pots to protect the roots - from installation in an external temporary container to wrapping in insulation materials. Moreover, the additional “clothes” can also be used as a finishing touch in the seasonal interior decoration.
Correction of watering for palm trees for the winter
All palm trees without exception require a slow reduction in watering in the fall. The correct period of adaptation to the winter regime of humidity is the basis for preserving attractive leaves, because less stress means less risk.
Watering is reduced depending on the rate of soil drying and conditions:
- for palm trees wintering in warmth, they continue to check the drying out of the soil, drying the substrate only a few centimeters;
- for palm trees wintering in light coolness, watering is reduced, drying the soil several times stronger - up to a third or half;
- for cold palms, watering is minimized to preserve the roots and greenery.
At the same time, it is worth following the recommendations for each individual species. Waterlogging is extremely dangerous for any palm.
Watering with warm water is the most important condition and measure that prevents many problems of palm development. And you should not forget about it in the winter, but only if “warm” means water, the temperature of which is several degrees higher than air temperature.
For all palm trees that are so thermophilic that they prefer wintering at 18 degrees and above, it is better to leave the water temperature at the usual level of 30 degrees even at the height of winter. For other species, they are guided by specific conditions.
In winter, regardless of the temperature of the palm trees, after watering, the water from the pallets must be drained immediately, without even waiting for the standard 5 minutes. If there are indications that the lower part of the substrate still remains waterlogged in palms, you can replace a regular pallet with a tank filled with moisture-absorbing materials (perlite, fine expanded clay and even sand).
By partially immersing the pots in such a base, it is possible to help more efficient distribution of moisture and prevent dampness in the lower third of the substrate in containers. The same technique can be used for accidental overflow in winter, insufficient drainage holes and compacted soil, especially when kept at temperatures below 12 degrees Celsius.
We maintain air humidity
Humidity is a critical condition for the normal conservation of palm leaves during the winter. It’s difficult for palm trees to adapt to all the shortcomings of winter maintenance. And very dry air at this time of the year leads to the appearance of dry tips, yellow spots on luxurious Wii, not to mention the accelerated drying of old leaves.
Spraying is the best method to prevent the loss of decorative palm. Winter spraying is carried out, if necessary, even for palm trees wintering in coolness - carefully, with warm water, sometimes by spraying replacing watering.
Fresh air but no drafts
In winter, drafts are very dangerous for all palm trees without exception. In this case, all palm trees, regardless of origin, and in winter require regular ventilation and access to fresh air, do not tolerate its stagnation.
Free air circulation is not less important with a cool winter than with a warm one. Plant protection should be given increased attention, covering palm trees from the flow of cold air, shifting or taking to other rooms. Any sudden changes in temperature and cold drafts will affect the condition of the plants.
If it is possible to carry palm trees from the premises, it is better to use it, returning the plants back when the temperature stabilizes.
If palm leaves are injured, spots appear on them or they dry out, requiring trimming, do not succumb to the temptation. In winter, any pruning on palm trees, even when it comes to the dry ends of wai, is strictly prohibited.
All areas affected during the winter can be cut off just before the start of growth - in early spring. At the same time, pruning rules remain standard: leaves affected in winter are cut as well as sheets that dry out at any other time of the year - leaving a strip of dry tissue, and not in living and healthy areas. Fully waiy can be cut off only after the entire leaf plate and stalk have dried.
In winter, you need to carefully monitor the cleanliness of the leaves. Gently wiping with a soft sponge or sweeping away dust with a brush is an important measure to prevent the spread of pests and impair effective photosynthesis.
Washing and showering even for compact palm trees in winter is very dangerous. Water procedures should be carried out only as a last resort, in case of severe pollution, using warm water and letting the plant dry in a warm room several days before being transferred to the usual environment.
