Ever had your beautiful potted plants turn yellow and die, even after watering? That soggy soil and waterlogged pot is a common headache for many Kenyan gardeners, especially during the rainy seasons.
Don’t worry, this guide gives you a simple, step-by-step solution. In just a few minutes, you can fix that drainage and save your plants from root rot. .
What You Need Before You Start
Before you get your hands dirty, gather these few things. You likely have most at home, and the rest are easy to find at your local hardware or plant nursery. Pole sana if you need to make a quick trip to town.
- The Problem Pot: The plant pot with poor drainage you want to fix. Check if it already has holes or if you need to make new ones.
- Drill or Nail & Hammer: To create new drainage holes if your pot doesn’t have any. A simple masonry drill bit (KES 200-500) from any hardware shop like Mr. Price Home or a fundi’s stall will work for ceramic or plastic.
- Drainage Material: Small stones, pebbles, or broken pot pieces (changa) to place at the pot’s bottom. You can collect these for free outside or buy a bag of gravel for about KES 100.
- Fresh Potting Mix: Old, compacted soil is part of the problem. A new bag of quality potting soil (around KES 300-600) from a nursery like Kenya Seed or your local agro-vet is a good investment.
- Watering Can: You’ll need water to test your improved drainage after you’re done. Sawa?
Step-by-Step: Step by Step Guide on How to Improve Drainage in Pots now in Kenya
Follow these six clear steps and you’ll have your pot draining perfectly in under 30 minutes, depending on the size of your plant.
-
Step 1: Remove the Plant and Old Soil
Carefully tip the pot on its side and gently ease the plant out. If it’s stuck, tap the sides of the pot. Shake off as much of the old, wet soil from the roots as you can. Be gentle to avoid breaking too many roots.
-
Step 2: Create or Clear Drainage Holes
If your pot has no holes, use a drill with a masonry bit to make several at the bottom. For plastic, a heated nail works. If holes exist, use a stick to clear any clogged soil or roots. This is the most critical step—without holes, water has nowhere to go.
-
Step 3: Add a Drainage Layer
Place a layer of your small stones or broken pot pieces (changa) over the holes. This layer should be about 2-3 cm thick. It prevents the soil from washing out and blocking the holes, keeping the water flow clear.
-
Step 4: Add a Thin Soil Layer
Put a small amount of your fresh potting mix over the stones. This creates a buffer so the plant’s roots aren’t sitting directly on the cold, hard drainage material. Pat it down lightly.
-
Step 5: Re-pot Your Plant
Place your plant back in the centre of the pot. Hold it steady and start filling in around the roots with the new potting mix. Gently press the soil down as you go to remove large air pockets, but don’t compact it too hard.
-
Step 6: The Final Watering Test
Water the plant thoroughly until you see water running freely out of the bottom drainage holes. This proves your fix worked! If water pools on top of the soil, your mix might be too dense—consider adding a bit of perlite or sand.
Common Problems and How to Fix Them
Water Still Drains Too Slowly
This usually means your potting mix is still too heavy and compact. Kenyan soil can be very clay-like. The fix is to amend your store-bought potting mix with coarse sand or small pieces of charcoal to create more air pockets and improve texture.
Soil Washes Out Through the Drainage Holes
If you see soil coming out with the water, your layer of stones or changa at the bottom is not thick enough. Simply empty the pot and add a thicker layer, about 4-5 cm, before adding the soil back. You can also place a single, larger flat stone over the hole first.
Pot Cracks When Drilling Holes
This happens if you drill too fast or without water on ceramic pots. To fix a small crack, you can seal it with waterproof glue from a hardware shop. For prevention, always drill slowly and use a little water to lubricate and cool the drill bit. Start with a small pilot hole.
Plant Wilts After Re-potting
This is transplant shock. The plant is stressed. Place it in a shaded, cool spot for a few days and avoid direct sun. Water it lightly but do not soak it again. It should recover in a week. If you need specific plant advice, visit your local nursery like Karen Roses or Nairobi Muthaiga Garden Centre for help.
Cost and Timeline for Step by Step Guide on How to Improve Drainage in Pots now in Kenya
The good news is this is a very affordable DIY project. Most costs are one-time investments for tools you’ll reuse. The timeline is mostly up to you and how many pots you have.
| Item | Cost (KES) | Timeline |
|---|---|---|
| Masonry Drill Bit | 200 – 500 | Buy once, lasts years |
| Bag of Potting Mix (50L) | 300 – 600 | Immediate use |
| Gravel or Pebbles | 100 – 200 (or free) | Immediate use |
| Labour (if hiring a fundi) | 500 – 1000 per pot | 30 mins per pot |
Hidden costs? Not really, but if your pot cracks, a new plastic pot costs from KES 150. Prices are fairly standard across counties, though nurseries in upmarket areas may charge slightly more. The entire process for one pot should take you 20 to 40 minutes from start to finish.
The Bottom Line
Improving your pot’s drainage is a simple, low-cost task that can save your plants from drowning. The key to success is ensuring you have enough proper drainage holes and using a light, airy soil mix. Once you get it right, your plants will thrive with much less stress for you.

Frequently Asked Questions: Step by Step Guide on How to Improve Drainage in Pots now in Kenya
Can I use regular garden soil instead of buying potting mix?
It’s not recommended. Garden soil is often too dense and compacts in pots, defeating the purpose of improving drainage. It can also harbour pests and diseases.
If you must use it, mix it with plenty of coarse sand and compost to lighten it up. A proper potting mix is a better investment for healthy plants.
How many drainage holes should I make in my pot?
For a small to medium-sized pot, aim for at least 3-5 holes. For larger pots, you might need 6 or more. The holes should be about the diameter of a pencil.
The goal is to have multiple exit points so water can escape quickly from different areas of the soil, not just the centre.
My pot is already planted and heavy. Do I have to remove the plant?
Yes, pole. To properly fix the drainage, you must remove the plant to check the roots, clear old soil, and add a new drainage layer at the bottom.
Trying to drill holes or add materials without removing the plant will likely damage the roots and won’t solve the core problem effectively.
How often should I check or improve drainage?
You should check if drainage is slowing down every time you re-pot a plant, which is typically every 1-2 years. Also check after heavy rainy seasons.
If you see water sitting on the soil surface long after watering, it’s a clear sign you need to investigate and possibly repeat the process.
Is it cheaper to just buy a new pot with holes?
Sometimes, yes. A new plastic pot with holes can cost from KES 150. Compare this to buying a drill bit (KES 200-500) if you don’t already own one.
However, if you have many pots or love a particular pot without holes, drilling is a one-time cost that gives you more flexibility and saves your favourite containers.
