The lemon tree, because of its low hardiness, is cultivated in pots in most regions, something which implies rather particular growing conditions and a certain know-how in terms of exposure to obtain a good harvest.
An adapted pot
Whether it is comfortably installed in a large orangery-type container or whether it is in a large terracotta pot, the lemon tree remains a fruit tree whose roots have need space to develop. In order to install your lemon tree in the best location for each season, think about it place on casters in order to be able to move it easily, because for the roots to have their ease, the pot will necessarily be quite heavy and bulky especially when filled with substrate humid.
Potted lemon tree exhibition in spring
As soon as frost is no longer to be feared and temperatures stabilize above 10 ° C night and day, you can consider taking your potted lemon tree out to the balcony, on the terrace or in the garden. Be careful, when it is out ofhivernage, it should be placed in full sun very gradually so as not to cause irreversible burns on the foliage, the indoor light is rarely the same as outside. Start by taking it out under shelter (awning, roof overhang, covered terrace, etc.) then, little by little, offer him the morning sun and finally a exposition due south and very sunny, if possible protected from prevailing winds. The habituation period will last from about a week to 10 days.
Start watering more regularly and do a intake of mixture of crushed horn and dried blood after making a voucher topdressing with some compost to promote the emission of new shoots and nourish this fruit tree gourmand.
Lemon tree exhibition in a pot in summer
In summer, the substrate dries very quickly in pots, especially if the lemon tree is exposed to full sun and in a windy area. So beware!
In the northern regions, the exhibition directly south and sunny can be maintained because it will guarantee good fruit set but always at the cost of sustained watering! Be careful, watering must be correctly dosed so as not to drown the roots and induce asphyxiation; let the substrate dry on the surface 2 cm before watering again. TO this time of year, if there is a little water left in the cup, there is no drama, especially when a very thick draining layer (pozzolana, gravel, clay balls…) has been placed at the bottom of the pot. The residual water should evaporate in a few hours at most.
In the southernmost regions a full southern exposure and totally sunny is to be avoided because it would be too hot in a pot, even with adequate watering.
In these regions, install your lemon tree exposed to the east or west so that it benefits from at least 4 hours of sunshine in the morning or evening while protecting it from the stinging rays of midday. If this proves impossible due to lack of space, install a shade sail, a parasol or better yet, a filet of camouflage which allows air and a few rays of sun to pass through without the situation remaining scorching; all your other potted plants will benefit.
Lemon tree exhibition in a pot in autumn
In the northern regions, at the very beginning of autumn, if the temperatures remain mild and above 8 ° C night and day, move your lemon tree to a south-facing exposure sheltered from the wind so that it benefits from as much sun as possible before its wintering. It will then be necessary to be very vigilant about the temperatures so that it does not take a cold snap!
In the southern regions, the sun can still strike very hard until the end of October, however, it becomes less hot. A South-East or South-West exposure is recommended in September, then, from mid-October, the lemon tree can be moved due South until the temperatures drop to 8 ° C at night. It will then be time to winter it indoors.
In the fall, start to space the waterings by watering only when the substrate is dry to 3 cm on the surface, whether you are growing your lemon tree in a northern or southern region.
Exhibition of the lemon tree in a pot in winter
In winter, the lemon tree grown in pots is installed frost-free, in a very bright and cool room, never in an apartment where the air is too heated and too dry and where the light will never be sufficient unless you are glued to a bay window facing due south (be careful of cold snap at night if the bay is not protected by a shutter and curtains).
Opt for an orangery if you are lucky enough to own one, a greenhouse, a veranda, or a winter garden. The brightness should be maximum with if possible a few hours of full sun in the morning or afternoon. In milder regions, remember to ventilate the room often in hot, sunny weather, as temperatures can rise very quickly!
In cold weather, install a backup heater so that the temperatures do not drop. never below 5 ° C.
The ideal temperature for wintering the lemon tree is between 5 and 14 ° C, watering will then be very reduced so that the substrate dries almost completely between two waterings. Obviously, during this cool rest period, the contributions fertilizer will be stopped.
