Watering quick guide

Choose the right drying target

Dry surface is not dry roots. Check below top dressing without damaging roots. A light pot or plateau supports inspection, but does not measure moisture. Drooping or softness can mean thirst or root trouble.

Houseplants: partial drying

Peperomia Bicolor — P31 / #7: partial drying, then water through and drain. Its fleshy leaves provide reserves; still avoid both persistent wetness and prolonged whole-pot drought. RHS guidance

Tricolor oyster plant — P32 / #8: check the upper 1–2 inches, scaled to actual root-ball depth. Water evenly and drain when ready; do not wait for whole-pot cactus-style drought. NC State guidance

Money tree — P21 / #3: the nursery tag suggests the upper 2 inches drying. Check the retained nursery core too; do not wait for prolonged whole-root-ball drought. Working identity: Pachira cf. glabra, genus confirmed by tag. Profile and tag evidence

Why: these foliage plants need root aeration without prolonged drought. In the planned north-door setup, new lights may change drying speed; check instead of assigning an interval. After an up-pot, compare the nursery core with the new outer mix. Do not wait for a cactus plateau.

Cacti: dry through

When: dry the root-zone mix through before watering during active growth. Extend intervals when growth and water use slow. Do not impose extra dry days to reach an arbitrary weight.

Why: stored water supports drying between drinks; prolonged wet roots increase rot risk. Water through and drain when ready. Frequent surface sprinkles do not replace wetting the root zone. University of Minnesota guidance

Exceptions: serpent cactus and monkey tail may need checking sooner during active growth. Monkey tail still shares P19's watering decision. Dragon's Egg is a probable Euphorbia obesa-type hybrid, grouped here by care rather than taxonomy.

Ordinary succulents: dry, then water

When: dry through, then check condition and growth. Echeveria, Sedum, Kalanchoe, elephant bush, Sempervivum, and tiger jaws belong here. Avoid prolonged forced drought during active growth.

Why: leaves store water, but these pots need not dry at the cacti's pace. Water the medium and drain; avoid pooled rosette water. One aging lower leaf is not a thirst signal.

Tiger jaws: follow dry-through care, not the Lithops leaf-replacement rule. Working identity: probable Faucaria tuberculosa, seller-labeled F. tigrina.

Shared P20 / #2 and P30 / #6: inspect every component and the shared root zone. Verify drainage before soaking, especially in the wooden box.

Kiwi aeonium: follow growth and rest

P22 / #4 — probable Aeonium haworthii 'Dream Color'. During active growth, let much of the mix dry, then water and drain. Avoid prolonged drought just to match the cacti.

During observed rest, reduce watering. Heat can slow growth, but the indoor environment can change seasonal timing; judge this plant rather than the calendar. Wisconsin Extension

Lithops: check each head

P35 / #9 — probable Lithops lesliei and probable Lithops salicola. These are photo-based working IDs; nursery labels say Lithops spp. Dry mix is only one part of the decision. Inspect all four visible heads for new leaves, old-leaf absorption, overall firmness, and a sound base. They were repotted together on September 23; both nursery groups were reported well rooted and all heads firm. Their separate species pages share one P35 watering and weight history.

• Replacing leaves: usually hold routine watering while old leaves supply the new pair. Outer-leaf shrinkage alone is expected, not a reason to refill the plant.
• Replacement complete and actively growing: consider watering when the root zone is dry and the current leaves show a real hydration need. A firm plant does not need water just because its pot is light.
• Unusual collapse or stalled recovery: inspect roots and conditions rather than automatically adding water or imposing an indefinite drought.

Group planting works without exact synchronization. If one group repeatedly needs water while another is still absorbing old leaves, reconsider keeping them together. Follow their actual condition and leaf stage. Wisconsin Extension, Living Stones Nursery

Split rocks: inspect the leaf stage

Royal Flush — P28 / G3; split rock — P36 / #10. Both use Pleiospilos nelii species guidance. P36's nursery label and photographs support that species, with no cultivar supplied; its September 23 repot check recorded a firm single pair.

Check dry medium, current-leaf firmness, and leaf replacement together; inspect the new inner pair when visible. A temporarily visible old pair can be normal. Persistent extra pairs can reflect excess watering, but neither leaf count nor a wrinkled outer pair decides the next drink. When watering is supported, wet the root zone and drain; let it dry before reassessing. Do not copy a fixed Lithops calendar onto split rock. SANBI's species account

Keep both split rocks and the Lithops outside automatic cactus feeding alternation. A dry reference, plateau, or date alone never authorizes their watering.

How to apply water and use the report

1. Check the plant and roots first. Unexpected wetness, softness, or decline needs inspection before more water.
2. Wet established roots evenly when ready. Apply slowly to the medium, drain, and empty the saucer. No group has a fixed milliliter dose. Watering-method guidance
3. Check fresh repots individually. Root damage, retained nursery mix, and leaf stage can change the first watering decision.
4. Use weights as context. A report candidate still needs a readiness check. Changed pots/mix need their own references.
5. Log actual care. Record watering and any measured post-drain weight. Choose fertilizer separately using the feeding guide.

Find every plant in its group

This index covers 42 botanical profile groups in 34 containers, plus the two whole-planter overview pages, as of September 24. A shared container is listed once with all its members. The removed silken pincushion and canceled orders are in their historical records.
