Domakihub Grow Tomatoes in Pots: A Practical Balcony Garden Guide
Everything you need for a productive container tomato harvest — from pot size to watering rhythm.

If you manage a home, holiday rental, or hotel in Greece and have a sun-drenched balcony or terrace, you already have the single most important ingredient for growing tomatoes in pots: heat. The video above walks through the full container method visually, while this guide breaks it into clear, ordered steps tailored to the Greek climate and to properties where garden space is limited or shared. Pot-grown tomatoes are a smart choice for any Domakihub-managed property — they impress guests, cost almost nothing to set up, and give you fresh fruit from May through October.
Why container tomatoes work so well in Greece
Greece's long, dry summers are nearly ideal for tomatoes. The plants need at least eight hours of direct sun per day and warm overnight temperatures above 15 °C — conditions that Greek balconies and terraces deliver from April through September without any extra effort.
Container growing also gives you precise control over soil quality and drainage, which is important in Greek coastal areas where native soil can be sandy, saline, or compacted. Growing in a pot means you fill it with exactly the right mix rather than fighting whatever the ground offers.
Choosing the right tomato variety for a pot
Determinate (bush) varieties — such as Roma, Patio, or Vilma — stay compact and stop growing when the first flowers set, making them the safest choice for pots under 30 litres. Indeterminate varieties like Cherry Gold or Sweet 100 keep growing all season and produce more fruit, but they need a larger container and a sturdy support.
For holiday rentals and terraces where aesthetics matter, cherry tomatoes are a popular pick: the clusters look attractive, guests can snack straight from the vine, and the smaller fruit tolerates irregular watering better than large beefsteak types.
5 steps to growing tomatoes in pots
- 1
Pick the right pot and fill it with quality mix
Use a container of at least 30–40 litres for a single indeterminate plant, or 15–20 litres for a compact bush variety. Terracotta is attractive but dries out quickly in the Greek summer heat — a dark plastic or glazed ceramic pot retains moisture better. Fill it with a mix of 60% good-quality potting compost, 20% perlite for drainage, and 20% aged compost or worm castings. Avoid using garden soil, which compacts and drains poorly in containers.
- 2
Plant deep and add support immediately
Bury the seedling up to its lowest set of true leaves — tomatoes can grow roots all along their buried stem, giving the plant a far stronger anchor and better access to moisture. If you are using an indeterminate variety, push a sturdy wooden stake or install a tomato cage at planting time rather than later, to avoid disturbing the roots once they have established.
- 3
Position for maximum sun and protect from wind
Place the pot where it will receive at least eight hours of direct sunlight. South- or west-facing terraces work best. Greek summers can bring strong winds, especially on islands and coastal properties, so position the pot against a wall or railing that breaks the wind without blocking the light. Knock it over once in a strong meltemi and you risk snapping the main stem.
- 4
Water consistently and feed weekly once fruiting begins
Inconsistent watering is the number-one killer of container tomatoes: it causes blossom-end rot and skin splitting. In peak summer, a large pot in full sun may need one to two deep waterings per day. Water slowly and thoroughly until it drains from the bottom, then allow the top 2–3 cm to dry before watering again. Once the first flowers appear, switch to a weekly liquid tomato feed (high potassium) to fuel fruit development.
- 5
Pinch suckers, harvest regularly, and watch for pests
Suckers — the small shoots that grow in the angle between the main stem and a side branch — will become full branches if left unchecked, reducing airflow and competing for energy. Pinch them out when they are less than 5 cm long. Harvest tomatoes as soon as they reach their full colour; leaving ripe fruit on the plant slows the production of new ones. Check the undersides of leaves weekly for whitefly and spider mite, both common in hot, dry Greek summers, and treat early with neem oil or insecticidal soap.

FAQ
- What is the minimum pot size for growing tomatoes?
- For a compact, determinate variety, a 15–20 litre pot is workable. For indeterminate or cherry tomato varieties that keep growing all season, go no smaller than 30–40 litres. A container that is too small dries out too fast and restricts root growth, leading to smaller fruit and stressed plants.
- How often should I water tomatoes in pots during the Greek summer?
- In July and August, a large pot in full sun can dry out completely within 24 hours. Check the soil each morning and evening: push your finger 3–4 cm into the compost, and if it feels dry, water deeply until liquid runs freely from the drainage holes. A self-watering pot or drip-irrigation timer is worth the small investment for holiday rentals where the property may be unattended.
- Can I grow tomatoes in pots on a rooftop or hotel terrace?
- Yes, and rooftops often have excellent sun exposure. The main risks are stronger winds and reflected heat from concrete or tile surfaces, which can scorch the lower leaves and dry out pots even faster. Use larger, heavier containers to resist wind, group pots together to help each other retain humidity, and consider shade cloth over the pots during the hottest midday hours of July and August.
