Echinocactus grusonii Hildm. is the correct and accepted name for the Golden Barrel Cactus. It was named and first documented by H. Hildmann in Deutsche Garten-Zeitung in 1886 and Monatsschrift für Kakteenkunde in 1891. Both publications are listed.

The genus Echinocactus Link & Otto was named by Johann Heinrich Friedrich Link and Christoph Friedrich Otto and documented in 1827. The title of publication is quite long… Verhandlungen des Vereins zur Beförderung des Gartenbaues in den Königlich Preussischen Staaten 3.

When this cactus was discovered, plants were dug by the thousands and sent to botanic gardens, palaces, and collectors throughout North America and Europe. Their native habitat is the Rio Moctezuma Valley in Mexico. In 1990, the area was scheduled to be flooded after a dam was built so a Mexican botanical garden removed them and other rare plants. Today, the Golden Barrel Cactus is one of the most common cactus in cultivation even though very few remain in the wild.

I bought my Golden Barrel Cactus from Wal-Mart on 2-1-16. Actually, I somehow bought two of them. They were in 2 1/2” (4 oz.) pots. The taller one measured approximately 2 1/2” tall x 2” wide and the shorter one approximately 2 1/8” tall x 2 1/4” wide. The label states: “Drought tolerant when established. Rugged tolerance of the elements; yellow flowers appear at the crown. Needs well-draining soil. Water thoroughly when soil is dry to the touch. Looks best with regular watering in hotter months.”

It is always strange to me how some critters, such as the crickets, always manage to chew on the cactus even though they have long spines. I am not sure what to do about it besides keeping them inside 12 months a year. 2013 was probably the worse year for crickets and I had many succulents that were damaged in one night. I had to start moving into the shed in the evening and back outside every morning.

I like growing cacti because many are so amazing. Most of them grow very slow so I measure them at least once a year.

Cactus are very easy to grow providing you follow a few basic rules. The main thing is probably the soil. They need a soil that is fast draining and very porous. They have this weird root system under the plant that isn’t very large at all. Ideally, your pot shouldn’t be much bigger than the root system but where in the heck would you get a pot like that? The best and simplest cactus soil recipe I have found is two parts potting soil with 1 part perlite and 1 part chicken grit. Some people are suggesting pumice instead of one or the other. I am going to experiment later once again. You can use very small pebbles if you can find grit. I have been wondering about aquarium gravel. The soil needs to be very porous so adding sand is not a good idea because it fills the air spaces. Cacti need a lot of good air space in the soil for their roots to breathe. Some types of potting soil become hard and compacted and I am trying to remedy this. If you have any suggestions, I would really like to hear from you.

I moved the potted plants inside for the winter on October 17 (2017) which is a little earlier than last year. You need to check your plants over carefully before bringing them inside to make sure some critters aren’t coming in. I always take them all to the basement first then take the cactus and succulents upstairs.

As with most cactus, they don’t require much water. I water my cactus along with my other potted plants when they are outside but I just go over them a little. During the winter, I hardly water them at all. Sometimes I may give them a light misting.

One thing is for sure, you don’t want to accidentally back into one of these. Handle with care!

The two Echinocactus grusonii are doing quite well inside. We all miss being outdoors, but seeing the snow outside makes them thankful to be inside.

All the plants were glad when warmer temperatures stayed around so they could get back outside.

I will add more photos from time to time, but not much exciting happens with cactus. Most of the time they just sit there and I have to measure them from time to time to see if they are growing.
