Indoor Pineapple

Indoor Pineapple

Pineapple on the windowsill is a real miracle. One thing is bad: acquaintances still strive to poke a finger at him, check whether he is real. As the fetus grew, the suspicion grew in me that if it had not been for me, they would have tasted it for a long time. Therefore, I keep a close eye on the indoor fruit.

Pineapple is a tropical plant, one of the few bromeliads growing on the ground. The leaves are long (up to 1 meter), dense, collected in a socket. After flowering, the inflorescence is transformed into one large fruit. According to data from the Guinness Book of Records, the largest pineapple weighed 8.06 kg.

The genus is not numerous, there are about nine species. At home, two of them are grown:

  • large-crested or real pineapple  – leaves with white stripes, with jagged edges;
  • pineapple cayenne  – leaves without thorns, the shape of the fruit is cylindrical.

It is an indispensable condition for the normal development of the inhabitant of the tropics. Pineapple loves bright light, prefers southern windows. If there is not enough light, its growth slows down.


The root system is sensitive to hypothermia. Despite the fact that the plant loves fresh air, it is inappropriate to leave it outside if the nights are cold. Recommended temperatures: + 25-30 o C in summer, + 21-24 o C in winter.


Soft water (see how to soften hard water for watering flowers) fill 2/3 of the rosette of leaves. The water should be warm or at room temperature. In the spring and especially in the summer, make sure that there is always water in the outlet. In hot weather, it will be useful to increase the humidity by spraying the soil in the pot. When the outside temperatures drop, it is better to water it carefully, an excess of moisture is worse for pineapple than drought.


Natural fertilizers (in the form of mullein infusion) or mineral fertilizers for flowering plants are applied every two weeks in the spring and summer. Alkaline fertilizers – limestone and ash – have a negative effect.


They are transplanted carefully so as not to damage the roots by transferring. The new pot should be only a few centimeters larger in diameter than the previous one. A drainage layer must be laid out on the bottom.

Pineapple needs loose, acidic soil. Ideal recipe: Leafy earth (1 part), humus (2 parts), peat (1 part) and sand (1 part).

Reproduction for Pineapple

Pineapple is propagated by children. After fruiting, the rosette dies off (as in other bromeliads, for example,  Tillandsia blue), but by this time two or three new shoots are formed, which can be separated with a knife and planted in the ground.

Experimental flower growers also grow plants from purchased pineapples, cutting off the top of the fruit and rooting it. This is done like this:

  1. Examine the fruit. The upper socket must be healthy and not damaged.
  2. The top with leaves and part of the pulp is cut with a knife, the pulp is removed, the crown is dried for 5-7 days. To avoid decay, sprinkle the cut with crushed coal.
  3. After the cut has dried well, it is pressed two to three centimeters into the ground (the composition of the substrate is the same as for the transplant) or rooted in a glass of water.
  4. The rooted shoot is covered with a jar or bag, after having made holes on it for ventilation. Keep in mind that it is necessary to regularly ventilate the appendage, otherwise, mold may appear.

After about 1-2 months, roots and new light green leaves sprout at the shoot. After that, it can be transplanted into a more spacious container.

Flowering pineapple on a 2-3 year after planting. The generative period can be stimulated with ethylene, which is poured directly into the leaf outlet once a day for a week. Prepare the solution as follows: mix half a liter of water and 1 tsp. Calcium carbide. After flowering, the fruit is tied, which ripens within a few months.

How to tell if a pineapple is ripe?

You can determine the ripeness of pineapple by the following criteria:

  • The main indicator of maturity is a sweetish smell. If it is not there, the fruit is not ripe.
  • Green is not an indicator that the pineapple is unripe. It all depends on the variety. But the leaves of the top should be dark green, without damage.
  • The crust should respond to pressure, but remain firm and firm.

It is believed that you can determine the ripeness of a pineapple by pulling the leaves from the top of the head. I did not conduct such an experiment on my fruit, so it was clear that it was ripe: the apartment had a delicious aroma and, by the way, tasted very pleasant.

After fruiting, the bush dies off, but this does not happen immediately. The mother plant leaves behind several daughter rosettes, from which pineapples can also appear later. It is better to plant them after they grow up, get stronger and acquire their own roots.

Problems with indoor pineapple that a florist should know about:

  1. Indoors where the air is hot and dry, pineapple leaves may curl. The tips of the plate dry and look ugly. It is necessary to increase the humidity of the air or spray the leaves more often. Also, the leaves can curl and curl if the plant is standing in a draft.
  2. Leaves become pale and dull if the houseplant lacks sunlight. Move it closer to the window, pineapple, even in winter, needs a lot of sunbathing, and in summer it can grow in direct sunlight.
  3. Rotting at the base occurs due to excessive watering. Repot and adjust watering.
  4. An exotic plant is most often attacked by a scale insect. The appearance of brown spots indicates its appearance. An urgent need to treat the flower. The pest is removed with a cotton swab dipped in an alcohol solution, and then the plant is treated with broad-spectrum insecticides.
  5. In addition to the scale insect, indoor pineapple can be harmed by spider mites, mealy, and root bugs. How to get rid of them, see the table “Diseases and pests of indoor plants”.

    It is, indeed, real – to grow a pineapple at home. We succeeded. Although the fruit itself did not grow as big as we used to see on the shelves in the store. A large fruit needs a large bush to support the weight of the fruit.
    We even tried our laugh. Pineapple is like pineapple, just a little greenish.
