Lucky clover - Oxalis tetraphylla

Sowing the lucky clover plant is easy, seeds, some soil and water and a suitable location - more is not needed. The basic procedure is similar both indoors and outdoors and is as follows:

1. When sowing in the pot should be paid attention to a very bright and warm location. In the garden the future growth place is chosen.

2. In a planter with potting soil, garden or potting soil or directly to the desired place outdoors, some seeds are applied at a close distance and only slightly covered with substrate.

3. The soil is thoroughly moistened or carefully poured. In the pot, the growth can be accelerated by applying a film. This is to be aired daily, so that no mold can form.

4. The soil is kept moist as much as possible during the first few weeks.

If the lucky clover plant is preferred to decorate the garden or balcony next year, autumn is the time for sowing. The young plants are then already larger and more robust when they reach the field. When sowing directly into the open, it should be noted that Oxalis tetraphylla is not frost hardy. The sowing should therefore take place in late spring after the last late frost.

plant out

Due to the sensitivity of the plants to low temperatures, preferred lucky clover plants are only planted outdoors after the last late frost. Special features to note there are not. The substrate from the culture container is carefully removed from the breeding tubers of the plants and brought into the soil at the desired location. Then it is easy to sprue.
Tip: Care should be taken not to damage the tubers. Otherwise, mold or rot may form. It is therefore better to leave a little substrate on the onions than to clean them with greater force.

Culture in the pot

As the lucky clover plant is not frost hardy as mentioned, it can be planted freely in the garden only cultivated as a year-old plant. Alternatively, it could be dug out in time for wintering and spent indoors. Different with the culture in the pot. Here is the four-leaf lucky clover with proper care easily perennial. However, it is also important to pay attention to a few factors:
  • Good drainage to prevent waterlogging
  • No frequent relocation
  • Pay attention to cool location
  • Fertilize regularly
  • Repot when the vessel is too small
High demands or peculiarities are not found in Oxalis tetraphylla.

to water

The lucky clover plant is watered with stale water as needed. That is, whenever the upper layer of earth has dried. During the hibernation and during the rest period from March to April, the irrigation can be reduced. It is then only poured so that the substrate does not dry out or only has a slight base moisture. When cultivating in the field, it is usually necessary to pour only during dry phases, but in the pot it has to be poured continuously.

As mentioned, the care of the clover is reduced by the use of fertilized or compost enriched substrate - since the additional fertilization in the first year in these cases is not necessary. Thereafter, there are two ways of nutrient supply. Either the lucky clover plant is repotted, replacing the spent with fresh nutrient-rich substrate.
Or from April to August the lucky clover is supplied once or twice a month with a liquid flower fertilizer. In the field, planting or untreated pond water can be used instead. It is also possible to sprinkle a little mature compost around the plant.

Repotting and repositioning

Often the copies of the lucky clover available on New Year's Eve are placed in pots that are too small, so that they look particularly lush. That is one of the reasons, for her often fast response. Repotting can be the salvation here. A conversion is often not necessary, since the lucky clover outdoors is anyway only one year old.
It should be noted in the implementation and Repot but in any case only that the underground tubers are not injured. They are carefully lifted from the soil and stripped of substrate residues before being placed in fresh substrate and covered with it. The best time for the measures is between April and May - as at the beginning of the growth period.


The propagation of lucky clover can be done in two ways. On the one hand by the seeds, on the other hand by division. How the propagation of the lucky clover plants by seeds takes place, has already been described. The seeds can either be obtained commercially or obtained from flowering Oxalis tetraphylla, if they form fruiting bodies after the flowers.
Faster and easier is the multiplication by division. Lucky clover forms the already mentioned subterranean breeding tubers. These storage organs are developed by the plant itself in increasing numbers, which is why the four-leaved lucky clover can spread in the garden in a relatively short time and can even be a plague without appropriate intervention.
If this effect is to be used in a targeted manner, individual tubers can be carefully detached and individually planted during potting or transfer. More is not necessary for the propagation of the lucky clover plant in this way. The daughter plants can be continued directly as the older mother plant.


If the lucky clover is also quite robust in itself and can spread quickly in winter-warm areas, then it is sensitive to frost and must be protected accordingly. The plants that spent spring and summer outdoors are therefore brought into the house at the end of the summer or at the beginning of the fall. Ideally, they should be at temperatures between 10 and 15° C and bright.
Oxalis tetraphylla planted in the field must be dug up in the fall or late summer and brought into the house if they are to survive the winter. Here they can be maintained in a planter as described above or only the tubers can be wintered without soil. But then at about 5° C, in a dry, dark room.
Note the following points in both cases:
  • Fertilize already in August or September at the latest
  • Pay attention to a cool but frost-free location
  • Continue to pour, but more economical
Again, the lucky clover is once again more of the easy-care and undemanding side.

Diseases, pests and care mistakes

Lucky clover - Oxalis tetraphylla

The clover is not sensitive to diseases and pests, they are found only in the rarest cases of the plants. Care mistakes, however, occur very frequently.
A typical problem is choosing the wrong location. Oxalis tetraphylla needs lots of light and low temperatures - but often ends up in a rather dark corner in the warm living room. The result is usually the formation of weak, long and soft shoots. The plant starts to appear thin and weak and usually loses leaf color. Preventive and saving is to put them on a cool window sill.
Other comparatively common mistakes in the care of the lucky clover are:
  • Waterlogging due to insufficient water drainage
  • Missing water supply
  • Spent earth or lack of fertilizer
  • To small planter
  • Freezing due to late entry into the house
If the lucky clover plant grows weakly, forms long shoots or brightens the rich leaf green or appears pale and yellowish, these factors should urgently be checked. With a timely intervention, the plants can usually save.
The lucky clover plant is an easy-to-maintain plant, which is a decorative enrichment through the four-parted leaves and the lush growth as a potted plant and in the garden. As long as he has a sufficiently bright and cool location, some water and nutrients available, he even rewards the caring with ornamental flowers.
