Boobie Cactus (Myrtillocactus Geometrizans Fukurokuryuzinboku)
The Myrtillocactus geometrizans, also known as Fukurokuryuzinboku, is a species of cacti that originates from north central Mexico and is a rare nursery cultivar. Here are some care requirements for this cactus:
-
Light: This cactus prefers bright, direct sunlight but can also tolerate some shade. In low light conditions, it may not produce as many flowers or grow as vigorously which will keep your cactus short.
-
Water: The Myrtillocactus geometrizans is drought-tolerant (as it stores water inside of it) and should be watered sparingly, only when the soil is completely dry. Overwatering can lead to root rot. You'll see your cactus "shriveling" which is a good indicator to water.
-
Soil: This cactus prefers a well-draining soil mixture that is slightly sandy or gritty. A standard cactus potting mix will work fine, but we suggest making your own by combining equal parts of sand, peat moss, and perlite.
-
Humidity: This cactus is relatively adaptable to different humidity levels but does best in a dry environment. Try to mimic their natural environment.
-
Temperature: This boobie cactus prefers warm temperatures and can tolerate temperatures as low as 40°F (4°C), but it is best to keep it above 50°F (10°C) whenever possible.
-
Fertilizer: During the growing season (spring to summer), the Myrtillocactus geometrizans can be fertilized every 2-4 weeks with a balanced, water-soluble fertilizer. If you're new to cacti, we suggest half dilutions to not over-fertilize. In winter, it should not be fertilized.
It's also important to keep in mind that the Myrtillocactus geometrizans (booby cactus) has sharp spines, so handle with caution so you can protect your skin when handling or planting. We suggest using tongs to grab and hold it in place.
