The tropical fruit can easily be grown on the windowsill. We’ll show you what you need to know about planting and propagating pineapples.
The pineapple ( Ananas comosus or Ananas sativus ) is one of the most popular tropical fruits and can actually be found in every supermarket. The bromeliad family member (Bromeliaceae) can also be grown at home. We’ll show you how it works.
Pineapple: ways of growing
Table of Contents
There are several ways to grow pineapples: Either you buy a young pineapple plant or you can regrow a pineapple using the regrowing method. The simplest and risk-free option is of course to buy a young plant that has already been grown. However, pineapple plants are not that easy to find in our latitudes. Growing back requires a bit of horticultural skill and patience to be able to harvest your first pineapple yourself at some point, but it is much cheaper. Whichever option you ultimately choose, we have worked out instructions for both variants for you in this article.
Pineapples can be grown both through purchased young plants and through the regrowing method
The perfect location for the pineapple
The pineapple comes from the tropics and therefore likes it warm and humid all year round. That is why it can only be grown indoors in our pots. She particularly likes a sunny spot on the windowsill (but not directly above the heater) or in the sun-drenched and heated winter garden. It thrives best when temperatures are consistently between 25 and 30 ° C. If the thermometer falls below 16 ° C, it becomes too cold for the tropical fruit.
So you should avoid that as much as possible. A high level of humidity is also important for the pineapple; it should be at least 60 percent. The best way to do this is to regularly spray the plant with water. The pineapple also wants to be well ventilated, so place it in a place where the air can always circulate well. On the other hand, she doesn’t like drafts at all.
The pineapple does not make any great demands on the substrate in the pot, it should only be loose and permeable. High mineral content in the substrate is also advantageous. The ideal pH value for pineapples is around 5.
What is the perfect location for the pineapple?
- No blazing midday sun
- Warm, between 25 and 30 ° C
- Never below 16 ° C
- Humidity at least 60%
- Well ventilated but no drafts
- A loose, well-drained substrate with a high mineral content
- Optimal pH: 5
Growing and planting pineapples
Before you plant your pineapple, first prepare the pot and substrate. Choose a sufficiently large planter, as the pineapple grows very large and sprawling. In addition, the pot should have a drainage hole and a saucer. Then put a drainage layer in the pot so that no waterlogging occurs. To do this, fill expanded clay or potsherds into the planter.
Now mix the soil by adding one part sand and half a part coconut fiber to three parts of ordinary potting soil. You can also enrich the substrate with a fertilizer with an organic long-term effect to provide the pineapple with sufficient nutrients from the outset. Our Gardender organic universal fertilizer contains all the important nutrients for pineapples and also releases them gently and slowly to the plant.
Now fill the planter one-third with the substrate. There the pineapple plant is placed in the middle. Then fill the pot with the rest of the substrate and water everything well. Remove excess water from the planter after a few minutes.
How is the pineapple planted correctly?
- Select a suitable planter
- Mix the substrate and enrich it with a fertilizer with an organic long-term effect
- Create a drainage layer
- Fill one-third of the pot with substrate
- Insert the plant in the middle
- Fill the pot with substrate
- Pouring on
Growing pineapple: instructions
Instead of growing them the traditional way, pineapples can simply be regrown using the regrowing method. First of all, of course, you need the fruit itself. It should have healthy foliage and be medium-ripe. The upper part of the pineapple is cut off with a sharp knife. Also, cut off all the pulp around the stalk so that only this one remains. The lowest leaves on the stem should also be carefully peeled off from top to bottom. About ten leaves should remain. The stalk including the tuft of leaves must remain intact, as otherwise, no healthy roots can form for the new plant. Alternatively, you can twist the stalk out of the fruit – this saves you from having to cut it.
To allow it to grow back, the stalk is cut off and excess leaves are removed
Now put the pineapple stalk in a vessel with water. The lower part of the stalk should be surrounded by water. A bright and above all warm location is very important for this step. After all, the pineapple doesn’t like the cold at all. You should also change the water regularly. After a while, you will see the first roots. If new roots have formed from the pineapple stalk, this can be planted in a container with a substrate. An extremely bright and warm location with a high level of humidity is also important here.
A window sill with a lot of daylight is certainly particularly good, but not directly above a heater. Now you have to wait because it can take up to two years for the plant to grow back and bear its own fruit. Regular watering should of course not be forgotten.
Step-by-step instructions – Regrowing pineapples:
- Select healthy, medium-ripe fruit
- Cut or unscrew the stalk with a sharp knife
- Remove all pulp from the stalk
- Remove all superfluous leaves except about 10
- Put the stalk in the water
- Set up in a light and warm location
- Change the water regularly
- As soon as roots have formed, plant in substrate
