Notes from a north-facing flat, mostly about not overwatering things.
I have killed a great many plants. Some of it was bad luck. Most of it was
watering on a schedule instead of watching the plant. This is where I write
down what worked, so I stop relearning the same lesson every spring.
Eighteen months of dropping leaves every time I looked at it sideways.
What changed was nothing clever: I stopped moving it. Same corner, same
quarter-turn every fortnight, water only when the top five centimetres
are properly dry. It has put out four new leaves since June.
A drooping plant looks like it wants more room. Nine times out of ten it
wants less water, or a brighter spot, or simply time. Roots circling the
drainage holes are the signal to size up — not sad leaves.
They arrived on a bargain calathea and spread to everything within a
metre. What eventually worked: isolating the lot, rinsing every leaf
underside in the shower weekly, and raising the humidity. Sprays alone
did nothing.
Not much that flowers, but a surprising amount of foliage. Aspidistra,
most ferns, pothos, ZZ plant and the tougher philodendrons are all
perfectly happy. Anything sold as “full sun” will slowly stretch and sulk.
A plant that is slightly too dry recovers in an afternoon. A plant that has
been slightly too wet for a month is often already gone.
Four things worth knowing
Light is the whole argument
Almost every problem people blame on watering is really a light problem.
Move the plant nearer the window before you change anything else.
Water the soil, not the calendar
Push a finger in. Dry to the second knuckle means water. Damp means wait,
even if it has been a fortnight.
Drainage holes are not optional
A decorative pot with no hole is a bucket. Keep the plastic nursery pot
inside it and lift it out to water.
New leaves are the only real report card
Growth means the plant is content. No new growth through a whole summer
means something needs to change.

Fern & Fig is written by one person with roughly forty plants, a watering
can that holds slightly too little, and no professional horticultural training
whatsoever. Entries go up when there is something worth reporting, which works
out at two or three a month.
