Question: Aquatic pachira
I have a nice apartment plan from PACHIRA. I have it since December and it is in a sheltered spot in my dining room, in front of a luminous window and I regularly water it now, but for about 10 days I have noticed that the leaves dry up and fall. What can it depend on? Give me some suggestions because I want to save it. Thanks, I'm waiting for your answer. Greetings. Rita Boero
Answer: Aquatic pachira
Dear Rita Rosa,
the pachires are plants originating in Central and South America, in particular they develop in areas with a tropical, humid and warm climate; therefore they are grown in the apartment, with winter lows that never fall below 5-8 ° C.
Despite the fact that they are plants that in nature can live near marshes or wizards, if they are grown in pots they do not like to have a land constantly immersed in water, especially if it is stagnant and firm. As it happens also for other evergreen houseplants, also the pachira in winter it spends its days in a period of semi vegetative rest, during which it generally does not produce new leaves or new branches; for this reason its cultivation needs tend to decrease.
So to cultivate yours well pachira It is good that you water it only when the ground is dry; that is, try to dip a finger in the soil, if it feels fresh and moist to the touch, it refers to watering for a day or two.
This means that in summer, when the plant is grown outdoors, with high temperatures and strong ventilation, you will have to water the plant every 2-3 days; while in winter, when your plant is at home, with a dry climate, but in vegetative rest, you may have to water it every 10-12 days. There is no fixed rule, it is necessary to check the soil: if it is soaked with water, let it dry.
What tropical plants then fear is excessively dry air, something that often occurs at home, especially if the heating system or air conditioner is active, which take away a lot of air humidity; for this reason, it is good to vaporize the foliage of our houseplants often. A vaporizer is used, or a sprayer that produces a large jet and with very fine droplets, almost vapor; if we don't have the time, the desire, the way to vaporize our plants often, we can place a cold humidifier next to them, which will constantly release humidity into the air.
Generally the symptom described by you, with leaves that dry up and fall off, is due to excesses of watering; clear that it could also be other reasons, for example an excess of fertilizers: the plants do not fertilize in winter, from September to March the administration of fertilizer is suspended, which will resume when spring arrives.
It could also be insects in the ground, which are eating the roots of your plant, in which case it is advisable to place systemic insecticide tablets in the jar, which will disinfect all the earth contained in the pot.
Repotting of the pachira acuqatica
As we also explained in the previous paragraph, the pachira is a plant that loves drained and neutral soils and does not grow in the best way in soils with water stagnation or stagnant water. For this plant the running water is much better even if the ideal is always a neutral well-drained soil.
As already mentioned, the pachira in winter slows down its vegetative activity and also lowering the temperatures we will have to be very careful with the waterings not to overdo the amount of water by always drying the soil well between an irrigation and the next. The pachira in fact, being cultivated in an apartment practically all over Italy, could suffer from these problems if we do not pay attention.
Once you understand what is the ideal growing medium of the aquatic pachira we will also have to start thinking about repotting, a necessary practice for this species at least once every two years. If the plant is healthy and cultivated in a suitable place, unless we can grow the hair containing its growth, we will have to repot it to these deadlines to allow it to grow regularly and steadily.
So we're going to buy some potting soil, a slightly larger pot than the current one in which we're going to put the plant and finally some expanded clay. The expanded clay will be placed at the bottom of the new pot, creating a draining layer of clay. At the top of this layer we will put some soil to create the bottom on which we will place the ground bread of the pachira plant. Let us remember to put the central and straight plant, after which we fill the empty spaces with soil until we fill all the gaps. Finally we compress the earth well around the roots and lower the level by banging the pot a couple of times on the ground. At this point, all we have to do is water the soil and add some more soil if it has dropped in volume.
