Question 1

What's the ideal temperature for your Blue cereus?

Accepted Answer

It is more suitable to keep the Blue cereus in a particular range of conditions. Temperatures the same as 75-90℉ (25-32℃) are ideal for it. During the early winter season, the temperature shouldn't go below 75℉(25℃) for Blue cereus. You can even move it indoors as it will have better protection from the extremes.

Despite that, the Blue cereus can survive in some extreme temperatures. Sometimes can survive in low temperatures like 50℉ (15℃), but it is not ideal. You should bring it inside if winter conditions are expected outside.

Question 2

How can I keep my Blue cereus warm in cold seasons?

Accepted Answer

It's advisable to bring your Blue cereus indoors to avoid the harsh winter conditions. People opt to buy different types of grow light to provide enough sunlight for the plant. However, if your home is not extremely dark, it is not essential to buy these lights. Keep your plants where they will get the most sunlight possible. There should be sufficient light to keep the Blue cereus thriving in winter. If you have several Blue cereus, then keep them rotating so that they all receive enough sunlight.

Question 3

What happens to my Blue cereus when the temperature is too high or too low?

Accepted Answer

Your Blue cereus can grow better in summers and do better in warm temperatures 90℉(32℃) but you should protect it from temperature extremes during hot climates.

However, during winter, it is better to keep your plant dry. Blue cereus do well in temperate climates having temperatures between 75-90℉ (25-32℃). However, some gardeners can expose their Blue cereus to extreme temperatures causing stress in their plants. While high temperatures ranging between 90℉ and 95℉(32-35℃) can help maintain the deep colors for Blue cereus, you must be careful when trying out such experiment. During the hot summer season extremely high temperatures can burn your Blue cereus damaging their stem and root system. During the hottest time of the day (when the temperature is extremely high), consider relocating your plant to a shaded place or protect them with a shade cloth.

Question 4

How should I adjust the temperature for my Blue cereus in different seasons?

Accepted Answer
