Planting substrate

There are substrates on the market suitable for succulents and cacti. They consist of peat, a part of coarse river sand and sifted leaf soil. This mixture provides good ventilation, excellent drainage and nutrient supply.

Watering

There is a misconception that cacti and succulents require infinitesimal amounts of water. Although they store water in their leaves and stems, they certainly won't thrive with too little water. Water every 10-15 days during the growing season (late spring, summer, early autumn) and much more sparsely in winter.

Lubrication

Lubrication should be done during the growing season and stopped in winter. There are fertilizers on the market especially for cacti and succulents. Use a fertilizer that is high in potassium, as it strengthens cell structures and plant resistance to disease.

Diseases and enemies

Cacti and succulents are infested with enemies and diseases. Their most common enemies are aphids, granules, thrips, blackflies and snails, and they are often infected by fungi.

It is suitable for rock gardens and potted gardens.
