Agave americana Marginata Care


All succulents, including Agave americana Marginata, require direct sunlight, so it is best to place the plant in the south or southeast window. In summer you can move it to the open balcony or veranda for sun exposure. If the windows of your apartment are facing north or northwest and west, the plant needs special lighting with a grow light.

Agave americana Marginata can withstand even the most scorching sunlight, does not burn, and does not require shade like some other succulents. But if the Agave americana Marginata was in a low-light place for a long time, then you should not immediately place it in direct sunlight. You have to get the plant used to the sunlight gradually.

agave americana marginata needs


All desert plants do not like excessive moisture. During the period of active growth, the plant requires moderate watering, that is, no more than 2 times in 7 days, so that the soil dries out between irrigations. Water 1-2 times a month in cold weather. It needs good drainage so that moisture does not stagnate. It is important that there is no water in the center of the rosette!

The simplicity of watering is attractive for office space and even industrial areas. If the Agave americana Marginata grows in a room with a lot of dust, you should wipe the leaves with it. This is quite problematic, as Agave americana Marginata have thorns and spines. To avoid injury to your hands, wipe the leaves with a damp sponge on a long handle.

The humidity of the air in the room where the Agave americana Marginata is located must be sufficiently dry. For the summer period, take the spiky beauty to the fresh air. Make sure the substrate dries completely before the next watering. There must be good drainage, the excess water that has accumulated in the pan must be drained.

You don’t have to place water tanks next to the plant as some plant growers do. Such a measure is necessary for other plant species, which require high humidity.


Due to its origin, Agave americana Marginata likes warm, dry air, so the climate of our city apartments is perfect for it. The optimum temperature is 68– 82°F. At a temperature of 64 – 68°F, the plant slows down growth and looks depressed. Spending some time at a temperature of 64°F and below can completely destroy the plant.


Agave americana Marginata soil is undemanding, and in the wild, it grows on rocky and sandy soils. It is only important that the soil is not too dense. Good drainage and adding sand to the universal soil mix solve all problems.

The best conditions for Agave americana Marginata are well-drained dry and sandy soils.


During the period of active growth, plant nutrition is necessary – in late spring and summer. Yes, fertilize the Agave americana Marginata plant, combined with watering, once a month. In winter, nourishing Agave americana Marginata is not necessary.

This plant does better undernourished than overfed. Use a fertilizer that is specially made for succulents, as it has everything you need for the plant.


Agave americana Marginata grows slowly and rarely needs repotting. If necessary, transplant young growing plants as soon as they have outgrown the container during spring. A new pot should be 1-2 inches larger in diameter. Take special care not to bury the rosette of the plant when repotting.

Also, avoid covering the stem with the substrate. Instead, cover it with pebbles for quick-drying at the roots of the stem. This is done so as not to limit the supply of oxygen.

It is very important when planting not to bury the neck of the plant, it should be slightly above the ground. Deep planting will cause the plant to rot.


agave americana marginata offsets

Agave americana Marginata propagates by offsets, which are formed at the base of the stem. Carefully separate them, dry a little to prevent rotting, and plant in a loose soil mixture. It is helpful to powder the cuts with cinnamon powder to promote healing. The first watering should take place three days after the appearance of the roots.

It is possible to propagate Agave americana Marginata seeds, but it is a very long and labor-intensive process. Sow the seeds shallowly in the ground in early March. Water the soil with the sprinkler and cover with clear glass or plastic wrap. Shoots appear in about 7-8 days. The best temperature for seed germination is around 75°F.

After the appearance of shoots, remove the film or glass and after some time transplant into pots with a diameter of 2.5 inches. After a year, transplant into larger diameter containers. Soil and drainage are the same as for adult plants. Agave americana Marginata seeds of various types are sold in nurseries and online.

Under natural conditions, Agave americana Marginata blooms over a period of 10 to 20 years. Then gradually thousands of small flowers appear on the stem. The plant dies after flowering because it gives all its energy to flowering and ripening seeds.
