How to grow and maintain Agave ocahui:

It thrives best in full sun to light shade. A south or south-east facing window works great.

It prefers to grow in well-drained soil. Use standard succulent or cacti potting mix.

It prefers warm spring and summer temperatures 70ºF/21ºC – 90ºF/32ºC and cooler fall and winter temperatures 50ºF/10ºC – 60ºF/15ºC.

In spring, water this plant when the top inch of soil is totally dry. Don’t let the soil become completely dry. In the winter and fall, when growth is suspended, water very lightly. Too much water can cause root rot or cause the leaves to become pale and flop.

Fertilize with a standard liquid fertilizer every two weeks during spring and summer. Do not feed during fall and winter.

It can be easily propagated from offshoots which is the fastest and most reliable method of agave plant production. Agave plants put out offshoots from the base of the mother plants that are easily removed to begin a new plant. Growing agave from seed produces a large number of plants quickly. A moist, sterile soil mix containing equal parts perlite and sphagnum peat is ideal for germinating seeds in a warm location with indirect light. The soil must stay lightly moist until the plants are established. A clear plastic covering helps keep the soil moist during the two to three weeks until the seeds sprout, then a daily misting keeps the seedlings moist until ready to transplant.

Pests and Diseases:
It has no serious pest or disease problems. Watch for mealybugs and scale.

Gardeners' Notes:

Central Phoenix -- I have a 20 year old Agave ocahui that is now about to bloom. The flower stalk is 10+ feet tall and growing but not yet with flowers. It is a solitary (non-pupping) plant in the ground against an east-facing block wall. This species really seems to benefit from heat. For the first 10 years of its life, the wall was a cedar fence and the ocahui grew slowly and didn't exceed 3 feet diameter. Once the cedar was replaced with a block wall, the ocahui grew rapidly to 6 feet diameter.
Note as of Dec. 31, 2015 -- Unlike some Agaves that live for a year or more after flowering, my A. ocahui died rapidly after flowering. It flowered in spring 2015 and was completely dead by October.

This medium-sized century plant forms an 18" tall x 3' wide solitary rosette of dark green leaves, edged with smooth reddish-brown margins. When the clumps mature, they are topped with a 9' tall narrow spike of bright yellow flowers.

Hailing from the northern Mexico state of Sonora, A. ocahui can be found on volcanic limestone up to 4,500' elevation.

I have not grown this plant. It rarely suckers. It is suitable for growing in containers due to its small size and symmetrical upright growth.
