The carpel of this plant has stigma and in warm regions, its flowering occurs between spring and summer, while in other areas, it blooms practically throughout the year.

Planting and care

All species of this genus you can multiply them by seed or graft. Its seedlings can be planted in permanent places, preferably after one and a half or two years of life.

With regard to seed reproduction, this is a time-consuming technique. First of all sufficiently prepare the soil, since it must contain a part of conifer, two parts of soil for heather and a part of sand, then you cover it with a plastic. The temperature should be cool, below 18 ° C.

Water the soil daily with warm water. The germination process can be long, since it can take more or less 1 month. Once the sprouts appear, they grow a little and gradually get used to the sunlight. The definitive strengthening of the seedlings occurs after approximately 2 months.

The advantage offered by reproduction by cuttings is that with the use of this method the plant blooms much faster than those produced by seeds. For this, cut the upper part of the shoots collected during the fall, these must be previously moistened, then plant them in a mixture of sand and peat. Make sure the ground is moist and the ambient temperature is within a cool range of 18 to 20ºC. Meanwhile, they must remain protected from the direct rays of the sun.

After about a quarter, you will see that the seedlings will show their roots. It is the right time for the fences to be progressively placed under the sun and fresh air. This adaptation stage takes a month. Afterwards it can be planted in the definitive place that you have in mind for it.

In the home, you must be careful with the arrival of frostFor this reason, before starting, cover the plantations with dry leaves or fir leaves. This will ensure a good winter and give the soil the necessary nutrients.

Natural fertilizers are usually applied during the sowing period, before flowering and after pruning. It can be applied by adding it to irrigation water. It is important to loosen the soil and add a cover that can be pine bark, chips and peat.

As you know it is a species that tolerates periods of droughtHowever, it is advisable to include frequent watering, always trying to keep the soil sufficiently moist. The water for irrigation must be at a certain temperature. If the plant is grown in a pot, then you can immerse it in water for about half an hour. As it is somewhat sensitive to ambient humidity, it periodically sprays the soil to counteract the effects.
