The optimal pH range for Yucca angustissima Engelm. ex Trel. var. elata Engelm. is between 6.5 to 7.5. It is important to avoid overwatering as the plant is susceptible to root rot.
Cultivation
Yucca angustissima Engelm. ex Trel. var. elata Engelm. is best grown in a well-draining soil mix that can be slightly sandy. It can be grown from seeds or stem cuttings. Yucca angustissima Engelm. ex Trel. var. elata Engelm. needs full sun for optimal growth and development.
Watering Needs
Yucca angustissima Engelm. ex Trel. var. elata Engelm. is a drought-tolerant plant and requires watering only when the soil is completely dry. During the active growing season, prioritize consistent moisture. However, it is crucial to avoid overwatering as it can cause root rot.
Fertilization
Yucca angustissima Engelm. ex Trel. var. elata Engelm. does not require much fertilization. Fertilize once a year during the growing season with a slow-release, balanced fertilizer. Be sure not to over-fertilize, as this can lead to salt accumulation in the soil, which can harm the plant.
Pruning
Pruning Yucca angustissima Engelm. ex Trel. var. elata Engelm. is not necessary. However, trimming off any dead or yellowing leaves can maintain the plant's overall appearance. Be sure to use sharp, clean tools and cut as close to the base as possible without injuring the stem.
Propagation of Yucca angustissima Engelm. ex Trel. var. elata Engelm.
Yucca angustissima Engelm. ex Trel. var. elata Engelm. can be propagated through seeds, offsets, stem cuttings, and rhizome division.
Seeds
The seeds of Yucca angustissima Engelm. ex Trel. var. elata Engelm. can be collected from the mature fruits, which are capsule-like and dry. The seeds should be sown in well-draining soil, kept moist, and placed in a warm, sunny location. The germination rate of Yucca angustissima seed may vary but usually takes between two and four weeks.
Offsets
Yucca angustissima Engelm. ex Trel. var. elata Engelm. can produce offsets, also known as "pups," from its base. These offsets can be removed carefully with a sharp sterilized tool and then replanted in well-draining soil. The new pup should have roots but may need time to establish itself before transplanting.
Stem Cuttings
Stem cuttings can be taken from healthy and mature plants of Yucca angustissima Engelm. ex Trel. var. elata Engelm. Cut a section of the stem of around 10-15 cm and remove all but the top few leaves. The stem should be kept to dry in a cool, dry place out of direct sunlight. Typically, after a few days, the healing at the wound will be complete and you can pot the stem in well-drained soil and place it in a warm, sunny location. It is essential to let the soil dry between waterings for the growth of the new plant's roots.
Rhizome Division
To propagate through rhizome division, dig up the plant and carefully separate the rhizomes. Each separated rhizome should have a few leaves and well-developed roots. Once done, replant the separated rhizomes in well-draining soil and water. Make sure not to overwater and keep the plant in a sunny location. The new plants will eventually grow to their full potential and start producing their offsets.
