Silver-green foliage starts with sunshine. A visual guide to finding the right window, checking the soil and keeping the roots well drained.

01 / Care at a glance
Four essentials, at a glance
Give it direct sun
Choose your sunniest window; a dim corner will not suit it.
Check before watering
Feel below the surface; do not water by the calendar.
Let water leave
Use drainage holes and empty the outer pot or saucer.
Look closely
Check new growth, fallen leaves and stems together.
02 / Water & drainage
Feel, water, drain
Check the mix
If it is still moist below the surface, wait and check again.
Water the root zone
When needed, water slowly until excess drains from the base.
Empty the saucer
Remove collected water before returning the pot to its place.
03 / Find the sunlight
An indoor tree still needs sun
Sun on the leaves
Observe actual sunlight reaching the canopy through the window.
Avoid the dark corner
Room lighting cannot replace a suitable sunny growing position.
Move gradually
Introduce stronger outdoor sunshine in stages.
04 / Leaves & light pruning
Observe first, then act
Leaf drop: check conditions
Check moisture and recent changes in light before adding water.
Inspect the stems
Look closely for scale-like bumps and sticky deposits.
Keep pruning light
Use clean secateurs to remove a dead twig; keep the main structure.
05 / Plant & pots

What does ‘indoor olive tree’ mean?
The store identifies this plant as Olea europaea, an evergreen tree with narrow, silver-green leaves. ‘Indoor’ describes a placement option, not shade tolerance. The cultivar is unspecified; this guide does not promise fruit.
Choosing a window and using extra light
Olives prefer full sun. Choose a window where direct sun actually reaches the foliage and watch how neighbouring buildings affect it. If that position is unavailable, consider a suitable sunny outdoor space or a properly specified plant grow light. Follow the light manufacturer’s distance and duration guidance; a decorative room lamp is not an equivalent.
When and how to water
Check below the soil surface, not just its colour. If still moist, wait; if drying, water slowly and let excess escape. A deep pot may remain wet below a dry crust. Do not let the whole root ball become persistently parched, and do not leave the roots standing in collected water. Adjust checks to drying speed.
Drainage, outer pots and repotting
Use an airy potting mix and a container with an unobstructed outlet. Pebbles in a sealed pot do not replace a drainage hole. For an outer pot, keep the draining nursery pot removable. Repot when the root ball needs more space; choose by root-ball size and maintain the existing planting depth.
Feeding without forcing growth
Garden Plus recommends checking whether the potting mix already contains fertiliser before adding more. When the tree is growing well, follow the chosen container-plant fertiliser label. Do not use extra fertiliser to treat unexplained leaf drop or poor light; correct the growing conditions first.
A light touch with pruning
Olives grow slowly. Remove dead or damaged twigs and make small shaping cuts when healthy growth resumes. Keep an open canopy; avoid a drastic cut-back. UK pruning calendars are not a fixed timetable for a Hong Kong home.
Yellow leaves, leaf drop and pests
A few older leaves can be shed naturally. A sudden increase needs investigation: check wet or very dry soil, light changes and stems. Scale insects can affect olives. Photograph persistent bumps or sticky deposits for identification before choosing treatment; one yellow leaf is not a diagnosis.
Hong Kong placement routine
Garden Plus suggests introducing stronger balcony sun gradually, maintaining airflow and avoiding direct air-conditioner blasts. After rain, check the outer pot for water. Secure outdoor containers and move them to shelter before strong winds. These are local practical recommendations, not a fixed overseas growing calendar.
Will it produce olives?
Flowering and fruiting depend on cultivar, maturity, light, suitable seasonal temperatures and pollination. A warm indoor position may not provide the seasonal conditions needed. Treat this as a foliage tree unless the current plant’s fruiting history is confirmed.
Choosing the plant and a separate planter
The plant has several pot options; confirm the selected combination and current dimensions. Its existing height reference is about 1.3–1.5 m, with measurement details to be confirmed. The separate planters below are style suggestions: check internal opening, usable depth and drainage. QG-027 lists a drainage hole; confirm drainage on the cement cylinder before direct planting. Illustrations show care actions, not the exact supplied plant or pot.

This guide focuses on home containers. Overseas calendars, greenhouse conditions and feeding regimes are not copied directly to Hong Kong. Local positioning and checking routines are practical Garden Plus recommendations.
