Thread Agave is one of popular Agave plants for the indoors due to its compact size. It is an evergreen perennial which forms a stemless rosette up to 3 ft across and up to 2 ft tall. The leaves are dark green to a bronzish-green color about 1 ft long. They bear fine thread-like filaments and hence the common name.
Thread Agave is native to Central Mexico from Queretaro to Mexico State. Thread Agave grows slowly and may take a long time to out grow its pot. Avoid disturbing the plant as much as possible as they do not like to be disturbed.
Thread Agave grows best in bright light with direct sunshine. A bright sunny window with as much sun as possible is ideal. Avoid exposing Thread Agave Plant to direct sunlight before acclimatizing it as it can get sun burned. Check out this guide on understanding light for houseplants.
Water your Thread Agave thoroughly during the hot season, when the soil begins to dry out. Water very infrequently in the cold months.
Avoiding wetting the center of the rosette as it can lead to rotting of your Thread Agave Plant. Water from the bottom instead. Use water that is at room temperature to avoid plant shock. Read more on how to water houseplants.
Warm temperatures between 21-320C are ideal for your Thread Agave. Though it can tolerate lower temperatures of up to 100C. The sudden change in temperature between day and night is excellent for this succulent.
Average room humidity is adequate for your Thread Agave. The plant does not require high humidity; it does not mind dry air.
Feed your Thread Agave monthly during the growing period with a water-soluble fertilizer, only in the first 2 years of growth.
Established plants do not require regular feeding; feeding may encourage blooming leading to premature death; Agaves are monocarpic, they die once they bloom leaving pups for propagation.
Repot Thread Agave only when necessary and taht is when the plant becomes pot-bound. Use a shallow rather than a deep pot as they have shallow roots. The pot should be only 1 size larger.
Ensure the pot for your Thread Agave has a drainage hole to prevent the soil from becoming soggy as it can lead to root-rot.
Though Thread Agave Plant is tolerant to most soils, it prefers sandy or rocky soil. To protect yourself from the sharp spinesof your Thread Agave, always wear gloves when handling this plant.
Prune your Thread Agave by cutting dead or diseased leaves with sharp strong shears, a long sharp knife or a curved pruning saw to minimize tearing and injury to yourself; the leaves have spines and are quite tough to cut.
Thread Agave can be propagated from seeds but they take long to develop. Propagation from offsets that form at the base of the plant is easier and much faster.
Seperate the offset from the mother and remove any damaged roots. Allow the offsets to dry (callous) for 1-3 days before potting. Select an offset which has several leaves.
Plant the Thread Agave offset in a moist free-draining soil. Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting. Water sparingly, water only when the soil is dry.
Overwatering during the cold period is the cause of wilted and discolored leaves in your Thread Agave. Reduce watering in the cold season to maintain the soil slightly moist.
Brown dry spots in your Thread Agave are due to underwatering during the hot season. Water thoroughly during the hot period when the soil begins to dry out.
Brown soft spots in your Thread Agave Plant are caused by Leaf Spot Disease which is enhanced by poor air circulation. Ensure there is free air circulation for your Thread Agave at all times. Read more on Leaf spot disease.
Rotting plant base followed by yellowing and shrivelled leaves in your Thread Agave Plant is an indication of basal stem-rot disease which is brought about by overwet conditions. Avoid overwatering, ensure the pot has a drainage hole and the soil is free-draining.
Thread Agave Plant (Agave filifera) produces a sap that can cause skin dermatitis in sensitive people. The leaves of Thread Agave bear sharp spines which may cause injury if handled with bare hands. Always wear gloves when handling the plant.
