Caigua Cultivation

It is very easy to grow Caigua from its seeds. While growing Caigua, the best time to sow the seeds is during the hot weather in early April. The seeds must at first be planted in pots and covered with compost soil. After the seedlings start to appear, they can be converted to a greenhouse or some other frost free location. The seeds should be planted in their final location only after all the chances of frost are gone. In the northern latitudes where the chances of frost are more, these plants should be provided protection against frost and cold for several weeks.

The plants should be adequately watered until they are well established. In dry weather, they may need more watering than required at other times. The soil used to grow these plants should be rich and fertile. A high-potash feed can be added to the soil to increase its fertility, though this is not necessary when the original soil itself is adequately fertile.

The rate of growth for these plants is very high. When the plants reach a height of around 4 or 5 inches, the tendrils start to appear. A hedge or a fence should be provided for the plant to climb and position itself so that it can gain clear access to adequate sun’s rays.

The flowers start to appear during the period from July through to September. Pollination is aided by hoverflies as well as other beneficial garden flies and insects. The flowers are small and cream-colored. They are followed by the appearance of a large number of small fruits with pointed ends. They grow as pairs or as single fruits.

In tropical climates, these plants can grow at an astounding rate, reaching almost 40 feet in one season. However, the growth rate is not that high in northern temperate climatic zones.

These plants are usually disease-free, have a high tolerance of cold and neglect and can grow well without addition of any fertilizers or pesticides.

Harvesting Caigua

A characteristic feature of the Caigua plant is that its production is proportional to the amount of fruits harvested. Thus harvesting more number of fruits will yield more plant production.

You can also save the seeds if you want to. For that you have to allow some of the fruits to mature. You can then collect the seeds and store them.
