The photosynthesis of cactus depends on its stem. Different from other plants, in order to adapt to its dry living environment, cactus leaves have evolved into hard needles, which can not carry out photosynthesis. Its main photosynthesis is its thick stems. The stem of cactus, like other plants, has chloroplasts for photosynthesis, which can not only make nutrients, but also store water.

Cactus maintenance

Cactus can promote plant growth in the sun, so we should see more sunshine, but shade it in midsummer to prevent sunburn caused by direct strong light. Opuntia dillenii, which has been stored in an unventilated place for a long time, is easily harmed by red spiders in dry and hot seasons, showing an aging yellow-brown color, which affects its growth and ornamental value.

Cactus is drought-resistant and waterlogged-resistant, so watering should be less and not more. Do not accumulate water in the basin, which is easy to rot its roots, so generally keep the basin soil semi-wet.

June to August is the season when cactus grows vigorously, with fast growth speed and high water consumption. Generally, water is poured once a day.
