Taking Care Of Trichocereus Huascha Cristata

Ideal conditions

Ideally, Trichocereus Huascha Cristata should be kept outdoors – there, it will be able to receive enough sunlight and will have plenty of room for unrestricted growth. Indoor keeping is also possible with this cactus, but only if you have a well-lit spot and enough space for it. Though this cactus doesn’t grow too big – up to about 3-6 feet – it can be difficult to keep indoors.


Trichocereus Huascha Cristata has typical cacti water needs – you need to only water it when its soil is dry. This cactus does not require much water. Moreover, it can suffer from overwatering and develop root rot.

In winter, the Trichocereus Huascha Cristata cactus will be dormant and thus will require little water. Suspend watering the cactus, or only lightly water it 1-2 times a month throughout winter.

Where to plant

Plant your Trichocereus Huascha Cristata in fast-draining cactus soil. Such soil will not accumulate water and will ensure that the roots of the cactus stay safe.

For extra drainage, add mineral grit (e.g. coarse sand, perlite, or pumice) to the potting mix. A 1:1 ratio between the soil and mineral grit should work well enough, but more mineral grit can also bring good results.

If you are intending to keep your Trichocereus Huascha Cristata potted, then be sure to pick a pot that has large drainage holes at the bottom so that the water can escape.

As mentioned above, Trichocereus Huascha Cristata is best to be kept outdoors. This cactus thrives in direct sunlight, and direct sunlight is abundant outdoors. With that said, if you have spots inside that are also directly lit all day, then you may keep Trichocereus Huascha Cristata indoors.

No matter where you decide to keep your Trichocereus Huascha Cristata cactus, on very hot days, make sure to move it a shaded location to prevent sunburn. Likewise, if your cactus is kept outdoors, make sure to bring it inside in winter to protect it from cold.

General care information

Trichocereus Huascha Cristata is a fairly slow-growing cactus, and it will take several years to reach a few feet in height. In the meantime, you should fertilize the soil of the cactus to ensure consistent growth.

Fertilization isn’t necessary if you’ve just repotted your cactus – fresh soil will have sufficient nutrients for growth. But if the cactus has been repotted a good while ago, then you may fertilize it once every 4-8 weeks in spring and summer with a cacti fertilizer diluted to half strength.

Repotting is another procedure that you will need to occasionally do, probably every other year when the cactus outgrows its pot. With that said, you may repot the cactus every spring or summer regardless of whether it has outgrown its pot – this will allow you to inspect the roots of the cactus, as well as introduce it to fresh soil.
