Almost every mistake with this plant comes from doing a growing-season job in the cool half of the year - cutting it hard as the light fades, repotting in the cold, or watering in winter on a summer rhythm. Match the job to the season and the plant looks after itself.
| Season | Main jobs | Watering | Feeding |
|---|---|---|---|
| Early spring | Hard prune, repot, start air layers | Once the top 2 in (5 cm) is dry | Start once new shoots appear |
| Late spring | Move outdoors after the last frost, acclimatize | Increasing as growth speeds up | Half strength every 3 to 4 weeks |
| Summer | Shaping cuts, take cuttings, check for mites | Frequently; pots dry fast outdoors | Half strength every 3 to 4 weeks |
| Early autumn | Last light trim, bring indoors before first cold | Easing off | Stop |
| Late autumn | Expect leaf drop after the move indoors | Much less; test before every water | None |
| Winter | Brightest window, watch for scale and mites | Every 2 to 3 weeks at most | None |
Spring: cut, repot, then feed
As soon as the days lengthen and you see the first new shoots, do the structural work. Prune to the height and shape you want, and repot if the plant has been in the same pot two warm seasons or is drying out within a couple of days. Do both in the same week if the plant needs both - it recovers from the pair together better than from two separate shocks a month apart.
Wait to feed. A newly repotted plant has fresh compost with nutrients in it, and a hard-pruned plant has no leaves to use a feed. Start a half-strength liquid feed about four to six weeks after the cut, once new shoots are extending properly.
Summer: outside if you can
A summer outdoors transforms an indoor evergreen ash. Once nights stay reliably above 50F (10C), move it out - but acclimatize it over ten to fourteen days, starting in full shade and moving it into more sun a little at a time. Going straight from a windowsill to open sun scorches every leaf on the plant, and those leaves do not recover.
Outdoors it will drink far more than you expect; a pot in wind and sun can need water daily in a hot spell. This is also when it grows hardest, so it is the right window for shaping cuts and for taking cuttings, and it is when spider mite populations build.
If you have no outdoor space, summer is still the season to get the plant right up against your brightest glass and to run any supplementary light on a long day length.
Autumn: bring it in early and expect the sulk
Bring the plant back indoors before the first cold nights rather than at the last minute - a warm plant moved into a warm room adjusts far better than a chilled one. Check it over thoroughly first: hose the leaves, inspect stem undersides for scale, and treat before it joins your other houseplants rather than after.
- Inspect and clean Rinse both leaf surfaces, look along stems and midribs for brown bumps, and remove any dead wood. Treat anything you find before the plant comes inside.
- Check the drainage holes Roots often escape into the ground over summer. Trim any that have grown out of the base, and scrape moss and debris off the surface of the compost.
- Put it straight in the brightest spot Do not park it in a dim hallway to settle in. The move is already a large drop in light; the brighter the landing spot, the less it sheds.
- Cut the watering right back A plant losing leaves in lower light uses a fraction of the water it did outdoors. Test the compost every time and expect to water perhaps every two to three weeks.
Winter: hold, do not push
Winter is a holding season. No feeding, no repotting, no structural pruning. Keep the plant against bright glass, off the heating vent, and water only when the top two inches (5 cm) are genuinely dry. Wipe dust off the leaves every few weeks - in the darkest months a film of dust is a real loss of light.
Check for scale and spider mites every couple of weeks, since heated dry air suits both. A plant that thins gradually all winter and rebuilds in spring is behaving normally; one that thins and keeps thinning through spring is short of light and needs to be moved.
The notes that make next year easier
Four records carry most of the value: the date of the spring prune and when buds broke afterwards, the dates the plant went outside and came back in, the watering gap in the hottest and coldest months, and the last repotting date with the pot size. Together those tell you your own plant's rhythm rather than a general one.
Add a photograph of the whole plant at the same point each year, taken from the same spot. Leaf density changes too slowly to notice day to day, and a side-by-side pair of pictures a year apart settles the question of whether the window you chose is bright enough far better than memory does.
