Buddha Lotus needs enough light to hold its rosette together. A draining pot and a drying interval matter more than an exact soil recipe.
Check whether the plant is a hardy houseleek
Buddha lotus is a trade name rather than a guarantee of identity. If the label confirms Sempervivum, use houseleek guidance; other rosette succulents sold under similar names may be tender. Do not test an unidentified plant's hardiness by leaving it through frost.
Give the rosette light and drainage
Choose suitable sun and an open root environment. Acclimate sheltered plants before exposing them fully. A compact-looking rosette still needs space for roots and offsets, with drainage that works through the whole container.
Observe offsets and flowering
A confirmed houseleek usually makes offsets, and a rosette that flowers eventually dies after that reproductive stage. That does not mean the entire clump is lost. Check the identity before interpreting a different succulent's behavior by the same rule.
Water for conditions
Inspect moisture before watering and avoid trapped water beneath the pot. Dense peat and a deep wet container can create problems even for an otherwise robust plant. Feed moderately only when the growing conditions justify it.
