Watering

Watering is where most indoor plants in Kuwait are lost — and almost never because someone forgot. Roots need water and air. This guide replaces the fixed schedule with four checks you can do in ten seconds, and it deals with the two things that make Kuwait different: hard, alkaline tap water and air conditioning that dries the leaves while the soil stays wet.

1. Check before you pour

The one ruleA dry surface is not a dry pot — lift it, do not just look at it.

A dry surface is not a dry pot. In an air-conditioned room the top two centimetres can be bone dry while the root ball underneath is still soaked — that is exactly the state that rots roots. Run these four checks:

1. Finger test. Push a finger 3–5 cm into the mix, or a third of the pot depth. Cool and damp means wait.
2. Weight test. Lift the pot. Learn what it weighs right after a full watering and what it weighs when dry. This is the single most reliable test and it costs nothing.
3. Probe. In pots wider than about 20 cm, or in dense mixes, use a soil probe and read it in two or three places — one reading tells you about one spot only.
4. Look at the plant. Slightly limp leaves that recover an hour after watering means thirst. Yellowing lower leaves with a sour smell from the mix means the opposite.

2. Water the whole root zone, once

The one ruleWater once, thoroughly, until it runs out of the bottom — then empty the saucer.

When the pot is ready, water it properly rather than often. Small daily splashes wet only the top of the mix and leave the deep roots dry while the surface stays permanently damp — the perfect setup for fungus gnats.

1. Take the plant to the sink or a tray. If it sits in a decorative cover pot, lift the nursery pot out first.
2. Pour slowly and evenly across the whole surface until water runs freely from the drainage holes.
3. Let it drain for five to ten minutes.
4. Empty the saucer or the cover pot. A pot standing in water is the most common cause of root rot we see.
5. Do not water again until the checks in step 1 say so.

3. Kuwait tap water: hard, alkaline, and it shows

The one ruleFlush every pot with plain water once a month, and never fertilise in the same session.

Kuwait’s desalinated supply is typically around pH 7.5–8 and carries a high mineral load. Two visible consequences on an indoor plant:

• A white crust on the soil surface and around the pot rim. That is salt, not mould.
• Brown, crisp leaf tips and new leaves that come out yellow between green veins — at that pH, iron in the soil is present but locked away from the roots.

Flush the pot once a month

1. Take the pot to the sink or outside.
2. Pour plain water slowly through the mix until roughly twice the pot’s volume has run out of the bottom.
3. Let it drain completely before it goes back on its saucer.
4. Do not fertilise in the same session — you would simply wash it away. Feed at the next watering.

Letting tap water stand overnight lets chlorine leave, but it does not reduce hardness or pH. If tip burn is persistent on a sensitive plant — calathea, maranta, carnivorous plants — use filtered water, distilled water or collected AC condensate for that plant only.

4. Heat, AC and dust: the Kuwait calendar

The one ruleAC dries the air, not the soil — move the plant out of the draught instead of watering more.

Period	What changes	What to do
November – February	Cool air, weaker light, slow growth. Pots stay wet far longer.	Stretch the interval. Keep checking rather than watering to a habit. Move cold-sensitive plants in when nights approach 10–15 °C.
March – April	Light and temperature climb quickly; growth restarts.	Intervals shorten week by week. Re-check every pot.
May – September	Extreme heat and dust outdoors; heavy AC indoors.	Bring tropical foliage indoors. Outdoor pots may need water daily or twice daily — early morning and after sunset, never at midday.
October	Heat breaks, growth slows again.	Ease off before the pots start staying wet.

What air conditioning actually does

AC dries the air, not the soil. A plant sitting in a cold, dry draught loses water from its leaves faster than the roots replace it, so the tips brown — and if you respond by watering more, the mix stays soaked and the roots suffocate. The fix is to move the plant out of the direct airflow, group plants together, and stand pots on a tray of damp pebbles. Misting raises humidity for a few minutes only; it is useful for cuttings, not as a humidity strategy.

Dust

Kuwait’s dust settles as a film that blocks light and blocks the leaf pores the plant breathes through. Wipe large leaves with a damp cloth every two to three weeks, supporting the leaf from underneath, and rinse small-leaved plants in the shower. Do it in the evening so no leaf goes into direct sun wet.

5. Self-watering pots and holiday watering

The one ruleFill a self-watering pot with mineral substrate, never potting soil, and let the reservoir run empty.

A self-watering pot holds a reservoir below the mix and lets the roots draw from it through a wick. Used correctly it steadies moisture for a week away. Three rules:

• Fill it with an airy mineral substrate — pumice, LECA or PON — not moisture-retentive potting soil. Potting soil wicks continuously and never dries, which drowns the roots.
• Let the reservoir run empty for a day or two before refilling. A reservoir that is never empty is just permanent overwatering.
• Top-water and flush it every month or so. Kuwait tap water leaves the same salts in the wick that it leaves anywhere else.

For a two-week absence, drippers and watering bulbs from plant irrigators work better than a full reservoir; group the pots out of direct sun first, and water everything thoroughly the morning you leave.

Fixing the two failures

The one ruleSoft yellow leaves and a sour smell mean too much water; crisp brown edges mean too little.

Overwatered

Soft yellow lower leaves, a sour smell, mushy brown roots, fungus gnats. Stop watering. Unpot the plant, wash the mix off the roots, cut away every brown or hollow root with clean scissors, and repot into fresh, airy mix in a pot with drainage — one size smaller if you removed a lot of root. Do not fertilise a plant with damaged roots.

Underwatered

Crisp brown edges, drooping that firms up after watering, mix that has shrunk away from the pot wall so water runs straight down the gap. Stand the pot in a basin of water for 20–30 minutes so the mix rehydrates from below, then drain it fully and return to normal checks.
