10 Kitchen Garden Mistakes Beginners Make (and Easy Fixes)
The gardening mistakes beginners make are nearly always the same ten, and most of them happen before the seed even sprouts: a pot with no hole, the wrong soil, too much water, too little sun. None of them means you lack a green thumb, and each has a fix that takes a few minutes, so here are all ten in the order they usually strike. Read on.
The ten, in one glance
- 1. No drainage holes
- 2. Garden soil only
- 3. Overwatering
- 4. Too little sun
- 5. Pots too small
- 6. Sowing too deep
- 7. Sowing out of season
- 8. Crowding
- 9. Feeding a sick plant
- 10. Giving up after the first failure

Why do my plants keep dying in the first month?
Pot, soil or watering can. The first three mistakes all end the same way, with roots sitting in airless mud, and together they explain most early losses in a pot garden.
- No drainage holes. A pretty ceramic bowl or a tin with a solid base becomes a pond after two waterings. Roots need air as much as water, and in a sealed pot they rot. Fix: every container gets holes in its base, four or five of about 1 cm for a 10 to 12 inch pot. Cannot drill it? Use it as an outer cover and keep the plant in a plain pot with holes inside.
- Garden soil only. Soil dug from a lawn or a plot behaves well in the ground and badly in a pot, where it packs down, cracks when dry and turns to brick by June. Fix: lighten it. Roughly equal parts soil, compost and cocopeat or coarse sand is a sound start, and the full recipe is in the potting mix ratio guide.
- Overwatering. Watering every morning because it feels caring is the most common way plants die. Fix: push a finger 2 to 3 cm into the soil. Dry means water until it runs from the holes. Damp means walk away.
Overwatering vs underwatering: how do I tell?
Both make a plant droop, which is why beginners pour more water onto a plant that is already drowning. Ignore the leaves. Go by the soil and the weight of the pot.
| Check | Too much water | Too little water |
|---|---|---|
| Soil 2 to 3 cm down | Wet, sometimes sour smelling | Dry and dusty |
| Pot when lifted | Heavy | Surprisingly light |
| Soil edge | Green film or tiny flies on top | Soil shrunk away from the pot wall |
| After watering | Stays limp | Perks up within a few hours |
The lift test: learn what a thirsty pot weighs
Right after a thorough watering, lift the pot or tilt it with one hand and notice the weight. Do the same two days later. Within a week your hand knows the difference between “full” and “empty” without digging into the soil at all, and that is how nursery workers check hundreds of pots in minutes. For pots too big to lift, leave a wooden skewer pushed to the bottom; pull it out, and if it comes up clean and dry, water.
How the schedule shifts between June and January is covered in how often to water potted plants in summer and winter. If the leaves are already yellow or drooping and you need to work out why, the yellow and drooping leaves guide goes symptom by symptom.
Why is my kitchen garden not growing?
If plants are alive but stuck, look at light and root room, because these two mistakes do not kill quickly. They stall.
- Too little sun. A bright balcony is not the same as a sunny one. Vegetables that fruit, such as tomatoes, chillies and okra (bhindi), want about 6 hours of direct sun; leafy herbs manage on 4. Fix: count the hours of real sun patches for one day, then grow what fits. Shady side of the building? Choose pudina, hara dhania and leafy greens, and stop fighting for tomatoes.
- Pots too small. A tomato in a 6 inch pot runs out of root space in weeks and dries out twice a day in summer. Fix: match the pot to the plant. Herbs and greens: 8 to 10 inches (about 5 to 8 litres). Chillies and brinjal: 12 to 14 inches (15 to 20 litres). Tomatoes and gourds: 20 litres or more.
Did you know? Dark plastic pots in full June sun can heat the soil enough to damage roots near the pot wall. Shading the pot itself, with another pot, a wet jute sack or a row of bricks, often helps more than shading the leaves.
Why do my seeds not come up?
Depth and date. Seed that is buried too far, or sown in the wrong month, fails quietly, and the beginner blames the packet.
- Sowing too deep. A seed carries a small packed lunch, just enough to push a shoot a short way to the light. Bury a tiny seed under an inch of soil and the food runs out before the surface arrives. Fix: cover a seed to about two or three times its own thickness. Very fine seed such as lettuce or tulsi is pressed onto the surface and barely dusted over.
- Sowing out of season. Hara dhania sown in May bolts to flower; okra sown in December sits and sulks. In the plains of Pakistan and North India the year splits roughly in two: cool season crops (dhania, methi, palak, peas, radish, carrots, lettuce) go in from October to December, and warm season crops (okra, gourds, cucumber, chillies, brinjal) from February to April, with a second sowing of many around June to July. Fix: check the month by month sowing calendar before opening any packet. In hill towns the warm season starts later, around April to May, and on the coast, where winters are mild, the cool season window is shorter.
- Crowding. Emptying half a packet into one pot gives a green carpet for a fortnight and then thin, leaning seedlings that compete for light and stay damp enough to rot at the base. Fix: thin them. Snip the extras at soil level with scissors, leaving the strongest at the spacing the packet gives, and eat the thinnings of dhania, methi and radish as microgreens.
Getting from seed to sturdy transplant has its own guide: seed starting at home.
Myth: a struggling plant needs more fertilizer
- Feeding a sick plant. Fertilizer is food, not medicine. A plant with rotting roots, or one wilting in heat, cannot take it up, and the extra salts in the soil pull water away from roots that are already struggling. Fix: find the cause first, which is nearly always water, light, pot size or season. Feed only plants that are actively growing, lightly: a handful of compost on a 12 inch pot once a month is plenty for most herbs.
- Giving up after the first failure. Every gardener has killed plants, including the neighbour whose balcony you admire. Fix: write down what you sowed, when, and what went wrong, then sow again, changing one thing.
Keep expectations fair. A pot garden adds fresh herbs, chillies and a few vegetables to the kitchen without ever replacing the sabzi wala, and judging it against that standard is the quickest road to mistake number ten.
Saucers and trays left full of water breed dengue mosquitoes, so empty them after every watering. Never use insect killer, phenyl or bleach on or near plants you eat, and store any garden chemical out of the reach of children and pets. On a rooftop, heavy pots belong along the walls and over beams, not in the middle of the slab, and nothing should sit on a parapet where it can fall. Wear gloves for soil and compost, cover cuts and wash hands afterwards.
What should I do differently this weekend?
Three checks. Turn every pot over and confirm the holes are open, push a finger into each pot before you reach for the can, and count your hours of direct sun once, honestly, writing the number down. Then start small: the balcony herb garden guide suggests three forgiving plants to begin with, not eight.
Common gardening mistakes: questions people ask
Why do my plants keep dying?
The usual cause is roots without air, from a pot with no drainage, heavy soil or daily watering. Check for open holes in the base and water only when the soil is dry 2 to 3 cm down.
What are the most common gardening mistakes?
No drainage holes, plain garden soil, overwatering, too little sun and pots that are too small. Sowing too deep, sowing in the wrong season and crowding seedlings come next.
Why is my kitchen garden not growing?
Slow growth with healthy looking leaves usually points to too little direct sun, a cramped pot or the wrong season. Count your sun hours and compare the sowing month with a local calendar.
How do I know if I am overwatering or underwatering?
Feel the soil and lift the pot. Wet soil and a heavy pot mean too much water; dusty soil and a light pot mean too little. Drooping leaves alone cannot tell you which.
How can I stop killing plants?
Start with three easy plants, give each a pot with holes and a light mix, and check the soil with a finger before watering.
Should I put stones at the bottom of a pot for drainage?
They are not needed if the pot has holes. A layer of stones takes up root space, and a single piece of broken clay pot over each hole is enough to stop soil washing out.
How deep should I plant seeds?
About two to three times the thickness of the seed. Large seeds such as peas and okra go roughly 1 inch down, and fine seeds are pressed onto the surface with only a dusting of soil.
Can I use soil from my garden in pots?
Not on its own. It compacts in a container and drains poorly. Mix it with compost and cocopeat or coarse sand so water and air can move through.
