Before selecting the final placement for the Selenicereus grandifloras, remember they are wild-growing plants native to Mexico, Florida, and Central America.

Cereus cactus requires full to partial sunlight for the best growth and can survive a temperature range of 5°C-41°C (41°F-106°F).

Indoor: Before deciding to grow it indoors, remember night-blooming cactus can become giants as they are tall climbing plants. And, don’t forget their prickly stems!

They reach up to 17cm-22cm and 38cm width. Yes, they are enormous! So, make sure you have enough space and sunlight (indirect) to allow them to grow happily indoors.

Outdoor: The Queen of the night plant needs light shading and something to support the weight of its gigantic wavy stems, resembling snake plants’ wavy stems.

So, if you are growing it outdoors in your garden or lawn, make sure to place it with a bamboo rod in a container or even with pine, palm, or any tree to get the support and shade it needs.

It is best to grow the night-blooming flower plant outdoors!

Note: They are not frost-tolerant plants which means they won’t do well in freezing temperatures. Move the plant indoors if you live in a cold zone, during winters.

2. Growing

The growing requirements for the Queen of the night flower are similar to any other cactus.

They prefer well-drained sandy soil mixed with compost. You can also use a regular cactus mix or combination of equal parts potting and sand mix.

Like other succulents, they don’t demand a high watering routine as they don’t like to sit in soggy soil and don’t do well if the soil is dried out completely.

Water once or twice a week in summers and once every two-three weeks in winters. Don’t overwater your Selenicereus to avoid root rot!

Use any organic cactus fertilizer to provide all the essential nutrients to the plant in vegetation or growing season, March to the end of September.

Note: Remember to keep a check on the soil moisture and watering routine during blooming season.

They blossom to huge white, cream, or yellow flowers that bloom almost over 1ft across.

But as compared to the spellbound show they put on every year, we must say it’s worth it!

And, you have to wait for the blooming until the plant matures. For instance, some people are lucky to see them blossom after 2 years, and some have to wait until four years.

It can take three-six weeks for them to be rooted. Here, watch a video on how to propagate Selenicereus grandiflorus from cutting:

Repotting: If there’s a plant that could go three to four years without repotting, it is this right here, the Selenicereus grandiflorus.

Regular and frequent repotting is not recommended for this plant as it requires vigorous roots to produce flowers.

Pot size: Try to repot it in a minimum of 10-inch pot to let it grow.

Pruning: Use a sterile sharp cutting knife or tree grafter kit to trim the shoots or get the offsets for a new plant.

Note: Be careful while handling night-blooming cactus as it has sharp edges or spines. Get any cut-resistant gloves lying in your kitchen or backyard before pruning.

Diseases

Although, Queen of the night is an easy-to-care-for plant just like Monstera Adansonii. Still, it is not immune to mealybugs, root rot, or other harmful insects.
