When purchasing pineapples in the market, you should pay attention to selecting some fresh top leaf crowns, so that you can take them home. The top leaf crowns can be directly pinched off by hand, or directly cut off with a knife. After removing the pulp, the leaves can be properly treated.
The top leaf crown of pineapple can be rooted by hydroponics, and the root system can only be transplanted into the soil when it grows well. Hydroponics will make the root system of pineapple leaf crown grow faster. Before hydroponics, in addition to removing the pulp from the crown of pineapple, the incision should be kept flat, and there should be no pulp residue. In addition, the 5~6 layers of leaves at the bottom of the crown should be broken off, and the leaves should not be soaked in water, otherwise they will rot, and the leaves should not be directly inserted into the soil, otherwise they will rot.
after the five layers of leaves at the bottom of the crown of pineapple are broken off, we can see some protruding white air roots, which will emerge continuously when soaked in clear water. Pay attention to avoid damaging the roots when breaking off, and pay attention to the fact that the incision at the bottom should be smooth and cut with a sharp knife.
The next step is to prepare a water cup, and soak the bottom of the leaf crown in water to avoid soaking the leaves in water. Just soak the bottom in water for about 2-3 cm, and then put it in a suitable position, with ventilation and light, and the relative humidity kept between 45-5%.
When maintaining hydroponic pineapples, it is necessary to change the water regularly, usually once a day or two, so as to keep the water fresh. In addition, it is necessary to keep the environment warm and the temperature between 2 and 28 degrees.
After two or three weeks, white roots can grow at the bottom of pineapple. After the roots grow vigorously, some loose and drained sandy soil can be prepared for cultivation.
at first, you should choose a smaller flowerpot with more drainage holes at the bottom. You can add some decomposed compost to the bottom of the pot, but you can't let these compost directly touch the roots.
after the pineapple is planted, it is necessary to water it once, first keep it in a bright place for about a week, then slowly see the light and gradually increase the light.
attention should be paid to watering pineapple potted plants regularly during the maintenance period, so as not to let the soil dry for a long time, but also to maintain a certain air humidity and a warm environment all the year round to avoid freezing.
After the potted pineapple grows for one or two months, it can be supplemented with fertilizer regularly, and organic liquid fertilizer can be supplemented every two or three weeks in spring and summer.
The pineapple will grow stronger after two years' potted maintenance. At this time, some zeolite can be put in the top leaf crown, which will help to generate calcium carbonate gas and promote the pineapple to breed flowers, so that it can bear fruit.
