Agave Shawii Summary

Agave Shawii Physical Characteristics

Each leaf has an average height of 1 to 2 feet, relatively broad, and curves upward. Leaves are characterized by curving spines along the margins. These have reddish spines, but the leaves also have a short, dark terminal spine. These spines stop animals from eating the leaves. Besides, the leaves can store water so the plant can live without rain for a while.

It is monocarpic and flowers only once after about twenty years of existence. It produces a large inflorescence whose height ranges from 6 to 14 inches. The inflorescence branches on its top third and produces yellow flowers. The rosette from which the inflorescence shot then dies. Each flower looks a bit like a bell or a small cup.

The roots of the Agave Shawii spread out and go deep into the ground. This helps the plant get water from deep down. Like the leaves, the roots can store water. This role allows this Agave can live without watering for a period of dryness. But, I recommend you shouldn’t let it arid for too long. Moreover, the roots also take in nutrients from the soil to help the plant grow. In addition, if you want to plant a new Agave Shawii, you can stick the root to help the new plant grow strong and get water.

Agave Shawii Care

Watering: Use the soak and dry watering method to water it. It is the easiest way to avoid root rot. I can not tell you the exact time to water your succulent, but you can notice the soil. That is the sign for you to water. Check 2.5 inches depth of soil whether it is dry. If yes, let’s water it! In growing seasons, don’t forget to water it often before winter comes.

Soil: The pottage you grow should have high gravel or pumice to facilitate drainage. Well-draining soil and a pot with drainage holes reduce the possibility of overwatering since the substrate won’t retain water.

Fertilizers: You can feed the plant once yearly with a slow-release fertilizer. The feeding is best done at the beginning of spring because the plant will utilize the fertilizer well throughout the growing season. Give it fertilizer rich in potassium and phosphorus with just a little nitrogen. Feeding should be done about once a year.

Light: This Agave loves sunlight. You should provide full sun most of the time (at least 6 hours). Though it likes full sun, under the harsh light from the sun, it can suffer leaf burn, so it should be positioned in partial shade. If you keep it indoors, you can simply place it near the window or use a grow light source for 12 to 14 hours. This is helpful in winter when you can not place it outdoors.

Temperatures: Warm is the ideal climate for this succulent. The ideal range can be between 21°C-32°C. If the temperatures drop below 10°C or go above 40°C, the plant can be damaged because it can not adapt to that weather. Remember that 10°C and 40°C is the limitation.

Agave Shawii Growth

This plant is suitable for specimen planting, succulent gardens, poolside, landscaping, and face containers. You can propagate it by plant division or offsets if it produces any.

It rarely needs pruning, but you should remove any dead or drooping leaves at the base of the plant to keep it neat. The plant will likely outgrow its pot occasionally, which will need repotting. This is usually when it doubles in size.

It is susceptible to pests you should look for, including mealybugs, thrips, eriophyid mites, and scale. Control them using organic systemic or contact pesticides. However, keeping the plant healthy is the best defense against these pests.
