About 60% of terrace pots fail the 30-second drain test before the monsoon. The growers we see lose plants in July aren't unlucky — they skipped this one weekend's worth of work in May. Drainage is the single highest-impact pre-monsoon job. Six steps. Two hours total. ₹0–₹500 in supplies.
Pour 1 litre of water into each pot. It should drain through within 30 seconds. Slower than that means the pot is going to flood inside the first heavy shower — and roots that sit in standing water start rotting in three days.
Use a stopwatch on your phone. Keep a notebook. Write down the pot number and the drain time. Anything over 60 seconds gets the full re-potting treatment in Step 5.
The single most common reason a pot floods is roots growing through the drain hole and matting it shut. Old soil + dust forms a paste; you can't see it from above; you only notice when the rain doesn't drain.
Tilt the pot. Poke through the drain hole with a stick or a thin screwdriver. Pull out anything you find. Re-test. If still slow, go to Step 5. Don't skip — a 30-second poke saves you a 30-minute re-pot later.
Wait for the next light rain (or pour a bucket from the wall corner). Watch where water flows. There will be at least one corner that pools — gravity finds it. Pots in that corner are going to sit in 2 inches of standing water for the entire monsoon.
Mark the wet zones with chalk or a sticky note. You have two options: move the pots to higher spots, or lift the pots 2 inches off the floor on bricks. Either works. Bricks are cheaper.
Every Indian terrace has at least one outlet that drains rain water off the parapet. Most are blocked by leaves, dust, bird droppings, and once — we saw — a tennis ball. When the parapet outlet blocks, water pools across the whole terrace and your pots become bird baths.
Go to the parapet edge. Find the outlet. Clear it by hand. Pour a bucket of water along the parapet 2 metres back and watch it run out. If it doesn't run out cleanly, there's another block downstream — usually at the floor drain in the building's plumbing. Tell the building maintenance.
Pots still draining slow after Steps 1 and 2 need the full treatment. The soil itself has compacted — air pockets gone, water can't get through. Often the bottom 2 inches are pure clay-like sludge.
Tip the pot out. Loosen the root ball gently — don't pull from the stem. Add a 1-inch gravel layer at the base of the empty pot. Re-fill with a fresh 1:1:1 mix of garden soil, cocopeat, and compost, plus a handful of perlite for monsoon airflow. Press the plant back in, water once, drain test again. Should now drain in under 20 seconds. We stock the mix components — see below.
Once you've done the bricks-and-poke-stick work this year, the lasting fix for next year is a permanent set of pot risers. They keep the bottom of the pot off the floor by ~2 cm so water can drain freely AND so the roots don't rot from sitting in the puddle below.
Cheap option: bricks (₹5 each, lasts forever). Mid option: ceramic pot feet (₹50 a set of 3, look better). Premium option: an iron rack with rollers (₹1,500–₹3,000 for a 4-pot rack). All three work. Pick what fits your terrace and your budget.
