Grow your own veg in pots and balcony boxes
No garden, no problem. Start with a few containers of salad, herbs and tomatoes on a balcony or windowsill and eat something you grew yourself this summer.
There’s a particular smugness to eating a tomato you grew yourself, and the good news is you don’t need an allotment or even a garden to earn it. A balcony, a bright windowsill, even a sunny doorstep can keep you in salad, herbs and a surprising amount of veg through the warmer months. Containers make it manageable: no digging, no weeding a whole bed, and you can move pots to chase the sun or shelter them from a cold snap.
The thing that trips most beginners up isn’t the growing — plants mostly want to grow — it’s water. Pots have a small reservoir of compost and dry out fast, especially terracotta in a breeze, so the single biggest favour you can do your plants is check them daily in summer and water before they wilt. Get that right and the rest is forgiving.
It’s worth being honest that a few balcony pots won’t replace your weekly shop. What they will do is reconnect you to where food comes from, give you the freshest possible herbs and leaves, and quietly cut the plastic punnets and air-freighted basil out of your routine. Start with one or two crops you actually like to eat, learn your spot for a season, and expand from there — that’s how a hobby grower turns into someone with a genuinely productive balcony.
How to do it
- Pick the sunniest spot you have — a balcony, windowsill or doorstep that gets at least 5–6 hours of light. South or west-facing is ideal; north-facing suits leafy greens and herbs only.
- Grab a few containers at least 20–30 cm deep with drainage holes. Old buckets, fabric grow-bags, a window box or a recycled crate lined with cardboard all work — no need for matching terracotta.
- Fill them with peat-free potting compost (not garden soil — it compacts in pots). Mix in a handful of slow-release organic feed if you have it.
- Start with easy, forgiving crops: cut-and-come-again salad leaves, radishes, bush tomatoes, courgettes, chillies, and herbs like basil, mint and chives.
- Sow or plant according to the packet, water in well, and keep the compost damp but not waterlogged — pots dry out far faster than open ground, so check daily in summer.
- Harvest little and often. Picking salad leaves and herbs regularly tells the plant to keep producing.
Pro tips & pitfalls
- Group pots together rather than spreading them out — they shade each other's roots, hold humidity and dry out more slowly on hot days.
- Tomatoes, chillies and courgettes are hungry: a weekly liquid feed (diluted comfrey, nettle tea or a shop tomato feed) from flowering onwards makes a huge difference to the harvest.
- Don't over-buy plants on day one. One tomato, a pot of salad and a couple of herbs is a genuine success — scale up next year once you know your spot.
What it's good for
Good for the planet
- Cuts CO₂ A pot of basil or salad leaves skips the refrigerated transport, plastic clamshell and supermarket trip that bagged herbs and leaves rack up.
- Cuts waste You snip exactly what you need, so no half-used bag of coriander slowly liquefying in the fridge drawer.
Good for you
- Boosts health Homegrown salad and herbs are picked minutes before eating, so they keep more flavour and nutrients — and tending pots is a gentle, mood-lifting daily habit.
- Saves money A €3 packet of salad seed yields months of cut-and-come-again leaves; a single supermarket bag costs €1–2 and is gone in two meals.
- Grows skills Container growing teaches you the basics — sun, water, feeding, harvesting — on a low-stakes scale you can build on each season.
