Question 1

How much sunlight does Fairy castle cactus need to grow?

Accepted Answer

Fairy castle cactus should get at least 6 hours of sun per day, and preferably more. An actual minimum number of hours can vary depending on the intensity of sunlight and other environmental factors, but it is unlikely that the Fairy castle cactus will get too much sunlight. They do fine with up to 14 hours of sun per day.

Question 2

What type of sunlight does Fairy castle cactus need?

Accepted Answer

Fairy castle cactus needs a lot of bright sunlight. As full-sun plants, they can thrive when given direct light or bright indirect sun. Some types may be able to survive with partial sun, but more sunlight is generally better.

Question 3

What will happen if Fairy castle cactus doesn't get enough sunlight?

Accepted Answer

Without enough sunlight, Fairy castle cactus will fail to thrive and grow. Common symptoms of inadequate sunlight include pale coloring, wilting leaves, and leaf drop. Fairy castle cactus may also exhibit etiolation (also called legginess). This condition occurs as the plant attempts to stretch toward the light source, leading to a sparse appearance and weak stems.

Question 4

What will happen if Fairy castle cactus gets too much sunlight?

Accepted Answer

Fairy castle cactus may develop shades of red, pink, or orange as a means of protection from excess sunlight, so many people like to cause mild sun stress to these plants during the summer. This is not harmful, and they will revert to their normal coloring when light levels decrease from autumn to spring.

If moved too quickly into direct sun, Fairy castle cactus can suffer from sunburn. This looks like white or brown spots on the uppermost leaves that have been exposed to the most sun. A sunburned plant should be moved to a shadier location and watered if needed. Sun-damaged leaves can be removed, and should be replaced by new growth over time.

Question 5

Does Fairy castle cactus need special care about sunlight during its different growth stages?

Accepted Answer

As with most plants, younger Fairy castle cactus will be more sensitive to strong sunlight and heat than a mature specimen. They should also be protected from direct sun immediately after being transplanted, either by a shade or by keeping the container in a shadier location until the plant is established and putting out new growth.

Question 6

Are there any cautions or tips for sunlight and Fairy castle cactus?

Accepted Answer

It is best to water Fairy castle cactus in the morning, particularly during the summer months. If water sits on the leaves or in the crown of the plant, it can burn the plant when the water heats up. It’s also best not to water in the evening, since cooler overnight temperatures slow evaporation and fungi or bacteria can develop in the moist conditions.

Fairy castle cactus grown in pots should be rotated occasionally to keep them growing symmetrically. Plants will normally grow toward the light source, so they can develop much more quickly on one side than the other if they are not rotated.

If Fairy castle cactus is allowed to get dusty, it will not be able to access sunlight to create energy. The dust acts as a barrier, so the plant may show signs of inadequate light even if it’s in a sunny location. Keep the leaves and stems clean by wiping them periodically with a damp cloth to avoid this issue.
