How to choose your cactus or succulent plant?

Selecting a cactus or succulent plant depends on several essential criteria. First, evaluate your space's light exposure: cacti generally appreciate bright light, while some succulents like Haworthia tolerate partial shade.

Consider the plant's mature size: columnar cacti can reach several meters, while compact varieties remain miniature. For beginners, opt for hardy species such as Echeveria or Christmas Cactus.

Don't forget to check the minimum temperature supported if you're considering outdoor cultivation. Some varieties tolerate light frost, while others require winter protection.

Expert guide: Growing and maintaining your cacti and succulents

The art of watering succulent plants

The most common mistake with cacti and succulents concerns watering. These plants store water in their tissues and dread excess moisture. During the growing season (spring-summer), water generously but wait for the substrate to be completely dry between waterings.

In winter, drastically reduce water: monthly watering is usually sufficient. Always use room-temperature water and avoid wetting the foliage of fuzzy species.

The ideal substrate for your succulents

Perfect drainage is essential. Mix regular potting soil with coarse sand, perlite, or pumice in 1:1 proportions. For the most demanding cacti, increase the mineral content up to 70%.

Add a layer of clay pellets at the pot's bottom and mineral mulch on the surface to prevent moisture rise and protect the plant collar.

Optimal light exposure and temperature

Most cacti require south or southwest exposure with at least 4 hours of direct daily sunlight. Indoors, place them near a well-lit window or supplement with horticultural lighting.

Respect a winter dormancy period with cool temperatures (10-15°C) to encourage spring flowering. This vernalization is crucial for many species.

Questions fréquentes

How often should you water a cactus?

Water your cactus only when the substrate is completely dry. In summer, this typically means watering every 10-15 days, and in winter, once a month is more than enough.

Why is my cactus becoming soft and yellow?

A soft, yellow cactus generally indicates overwatering causing rot. Immediately stop watering, check drainage, and repot if necessary in dry, well-draining substrate.

How do I get my succulents to bloom?

To stimulate flowering, respect a winter dormancy period with less water and cool temperatures (10-15°C). Resume normal watering in spring and ensure maximum light exposure.

Can cacti be grown outdoors year-round?

Some species tolerate light frost (-5°C) like Opuntia or Sedum. However, most require winter protection or pot cultivation to bring indoors during winter.

How do you repot a spiky succulent plant?

Use thick gloves or tongs to handle spiny cacti. Choose a slightly larger pot, add well-draining substrate, and wait a week before the first watering.

My succulents are becoming etiolated, what should I do?

Etiolation (abnormal elongation) indicates insufficient light. Move your plants closer to a south-facing window or invest in suitable LED horticultural lighting for plants.

What is the minimum temperature for indoor cacti?

Most indoor cacti tolerate temperatures between 10 and 30°C. Avoid temperature shocks and cold drafts that can damage succulent tissues.
