Watering Needs

The torch cactus is a drought-tolerant plant that requires minimal watering. During its active growth of the growing season, which is typically from spring to fall, the Trichocereus grandiflorus can be watered once in 2-3 weeks or whenever the soil feels completely dry. It is important to avoid overwatering the torch cactus, as this can lead to root rot. In the winter months, when it is dormant, it can be watered even less frequently, as it is not actively growing. 

When watering the Trichocereus grandiflorus, it is important to use a well-draining soil mix and a pot with adequate drainage and holes. This will help prevent excess water from accumulating in the soil and causing root rot. Overall, the torch cactus is a low-maintenance plant that requires minimal watering, making it a great choice for busy gardeners or those who live in dry climates. 

Light Requirements

The torch cactus requires bright full sunlight to thrive. It can be grown both indoors and outdoors, but it is important to protect it from direct sunlight, especially during the hottest part of the day. If the Trichocereus cactus is exposed to too much direct sunlight, it can become sunburned and damaged. 

When grown indoors, Trichocerus grandiflorus can be placed a few feet away from a south-facing window that receives bright but indirect light. It is important to rotate them occasionally to ensure that all sides receive adequate bright light throughout. If it is not receiving enough bright light, it may become leggy and stretched out. If this occurs, the Trichocereus cactus can be moved to a location with brighter light or supplemented with artificial light. 

Optimal Soil & Fertilizer Needs 

The torch cactus requires a well-draining cactus soil mix that is specifically formulated for cacti. This type of soil mix typically contains a high proportion of sand or perlite, which helps to improve drainage and prevent water from accumulating around the roots. Instead, make or buy a well-draining potting mix, or ideally, use our specialized cactus potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your cactus to thrive. 

When it comes to fertilizing the Trichocereus grandiflorus, it is important to use a fertilizer that is specifically formulated for cacti. This type of fertilizer typically contains a high proportion of potassium and phosphorus, which can help to promote healthy growth and flowering. It is important to avoid using a fertilizer that is high in nitrogen, as this can cause the grandiflorus cactus to become leggy and stretched out. The torch cactus should be fertilized once a year during the growing season in the spring.
