How can pineapple seeds be sprouted

Grow tropical plants on the windowsill

Planting time is also in autumn and winter. Lots of tropical seeds, tubers, and cuttings are just waiting to be brought to life. Only a few tools are required to grow a tropical garden in your home.

Tinker tropical greenhouse out of PET bottle

For each type of plant you need a set consisting of a flower pot with saucer or planter, peat-free potting soil and a translucent PET bottle. The diameter of the flower pot should be only slightly larger than that of the PET bottle. Cut off the bottom of the bottle and place the bottle in the flower pot - the little tropical greenhouse is ready. It should be placed directly on a radiator or on a floor with underfloor heating. A cork coaster protects against the cold on a cold window sill.

The sowing of melon, papaya and co

Many fruits have seeds that can be sown. You can even germinate Andean berries (physalis) and cucurbits such as melons, squash and kiwano. Caution: The seeds of tropical plants, unlike native fruits, begin germinating immediately. The pulp must always be thoroughly removed beforehand to prevent rot. This works best with warm water.

A plant can easily be grown from the dried seeds of the prickly pear.

The many seeds of the dragon fruit sprout particularly well and the prickly pear also shows acceptable results. Citrus fruits, chilli, date palm and papaya are particularly popular. The seeds germinate reliably and the plants can be kept indoors for many years - in summer also outdoors (with the exception of papaya). Very small climbing plants develop from the seeds of passion fruit, granadilla and kiwi.

Plant avocado and mango seeds

For an avocado plant, simply plant the core in soil or let it germinate in water.

The large seeds of the avocado can either germinate in a water glass or planted directly in the potting soil. To do this, press the broad side of the seed into the substrate, about a third to half should still peek out. It is more difficult to sow mango seeds. In the wild, the kernels of animals are pre-digested for this purpose. In order to germinate an undigested mango kernel, the kernel must be opened carefully, for example with water pump pliers - without damaging the embryo. This is removed and pressed into the substrate. It has a small "nose" that should still look out after planting. Regular watering and a location with 22 to 25 degrees are necessary.

A sowing attempt with all other plants is a lot of fun and works as follows: The tropical seeds are freed from the pulp and scattered on a peat-free substrate. With a sieve, the substrate is sifted over the thickness of the seed. A small greenhouse is made from a PET bottle - as described above - and placed over the seed. This "greenhouse pot" is placed in a bright and warm place. Germination takes two to eight weeks.

Plants out Pull cuttings

To propagate a pineapple, a cutting is made from the fruit.

In the case of the pineapple, the brown seeds are in every honeycomb. Harvesting is difficult and germination is not always promising. It is easier to use the head of the pineapple fruit as a cutting. When buying, you should make sure that the leaves on the top are still all there and firmly attached. If the leaves can be loosened easily, the fruit is deliciously ripe, but the tuft does not grow on.

Remove the tuft from the fruit and then remove the lower leaves so that about five millimeters of the stem are visible. Place the bowl in a glass filled with water. The interface should stand on the water and refill evaporated water. Roots form within four to six weeks, after which the pineapple pot can be placed in peat-free potting soil.

Germinate ginger and Jerusalem artichoke

Ginger bulbs are good for germination. To do this, press the tuber halfway into peat-free potting soil, water it and place the pot in a light and warm place. Decorative plants can also be easily grown from the sweet potato tuber. Place the tuber with the tip down in a tall glass and fill one-third with water. After about five weeks, shoots with roots appear, which can be separated and potted. It is also possible to plant a whole tuber directly in peat-free potting soil.

Another vegetable that grows well is Jerusalem artichoke. A preculture is possible from April, but actually not necessary. The tubers can simply be planted in fresh, well-fertilized garden soil in May. However, these plants easily spread over a large area. The plant cannot be stopped by frost either. A root barrier consisting of a cut-open bucket is therefore recommended.

Further cultivation of tropical plants

When further cultivating the plants, the home climate of the plant must be taken into account. Kiwi plants can be cultivated outdoors all year round - on trellises or house walls. Annual Andean berries, chillies and peppers also bear a lot of fruit in warm summers when they grow on the terrace, balcony or in the garden. The tubers of sweet potato and Jerusalem artichoke, melon, pumpkin and kiwano develop well outdoors. Dragon fruit, mango, avocado, pineapple and papaya need room temperature and lots of light.

All pots or tubs with citrus plants, "Christmas pines", passion fruit and date palms can spend the summer outdoors. As soon as the temperatures drop continuously below ten degrees at night, these plants have to go inside again, in a heated and bright room.

Pull the papaya yourself

They are delicious, healthy and can even be kept in our planters: papayas. With a little patience, a new plant will soon grow from the seeds of a fruit. more
