Your houseplant care calendar

A practical routine for an east–west-facing home. The calendar tells you when to check. The soil test on each plant tells you whether to water.

One rule for every pot

Water thoroughly, let excess run out, then empty the saucer or decorative cover. Never leave roots standing in water.

Repeat each week

The weekly rhythm

Monday

Moisture-first round

#3 Sweet basil · #15 Spikemoss · #21 Baby’s tears

Check these every Monday even if they were watered recently. Baby’s tears and spikemoss should never become crisp.

Tuesday

Ferns & humidity

#16 Lemon button fern · #22 Bird’s nest fern · #24 Asparagus fern

Check the root ball and remove dead fronds. Water only when each plant reaches its soil trigger.

Wednesday

Tropical foliage

#2 Fishbone prayer plant · #9 Spider plant · #12 Philodendron Brasil · #13 Poinsettia · #14 Curly spider plant · #17 Heartleaf philodendron · #18 Swiss cheese plant · #20 Golden pothos · #25 Croton · #28 Philodendron Brasil

This is the main weekly check for prayer plants, climbers, spider plants, poinsettia and croton.

Thursday

Fast second check

#3 Sweet basil · #15 Spikemoss · #16 Lemon button fern · #21 Baby’s tears · #24 Asparagus fern

During the current 24°C spell, moisture-loving plants may need a second check. Do not automatically water them all.

Friday

Trailing plants

#8 White striped inch plant · #10 Watermelon dischidia · #11 Zebra inch plant

Check moisture, remove dead growth and look for pests while handling the vines.

Saturday

Dry-tolerant plants

#1 Flaming Katy · #4 Ox-tongue succulent · #5 Dragon tree · #6 Cylindrical snake plant · #7 Jade plant · #19 Jade plant · #23 Eve’s needle cactus · #26 Baby rubber plant · #27 Variegated snake plant · #29 Baby rubber plant

Check weekly but expect many to remain dry for two or three weeks. Never add a token splash.

Sunday

Reset

Empty every saucer and cover pot, rotate light-seeking plants, wipe leaves and record anything watered. No routine watering today.

When the hot spell ends: keep the same check days, but expect watering intervals to lengthen. In winter, most plants will need substantially less water.

Do these first

Four plants need intervention

White striped inch plant

Plant 8

White striped inch plant

Cut away all yellow/brown growth. Take several healthy 8–10 cm tip cuttings as insurance. Check roots: trim black/mushy roots and repot if the compost smells sour or stays wet.

Watermelon dischidia

Plant 10

Watermelon dischidia

Sparse vines and dieback suggest root stress or erratic watering. Remove dead vines, inspect roots and repot into a chunky orchid-style mix if the current mix is dense.

Open full care card ↓
Baby’s tears

Plant 21

Baby’s tears

Severely desiccated. Trim all crisp growth, soak once and look for fresh green shoots over 2–3 weeks. If stems are brittle throughout and no regrowth appears, replacement is more realistic.

Eve’s needle cactus

Plant 23

Eve’s needle cactus

Growth is elongated and sprawling from insufficient light. Give much stronger light, remove dead material and consider repotting into a heavy terracotta pot with gritty cactus mix.
