Domakihub Container Gardening for Beginners: Grow More in Less Space
Everything you need to start a thriving container garden on a balcony, terrace, or courtyard in Greece.
Reviewed by Domakihub garden pros · 2026-06-23 · 5 min read
Container gardening lets you grow herbs, vegetables, and flowers almost anywhere — a sun-drenched Athens balcony, a Mykonos holiday villa terrace, or a hotel courtyard with a single shaded corner. The video above walks through the core technique visually; this guide distills the practical steps so you can get pots in the ground (or on the tiles) this week. Greece's long growing season and reliable sunshine are a genuine advantage, but containers have their own rules that differ from open-bed gardening.
Why containers work especially well in Greece
Most Greek homes and holiday rentals lack a traditional garden plot, but almost every property has a balcony, roof terrace, or courtyard that gets six or more hours of direct sun each day. Containers let you exploit that sunlight without needing soil in the ground. They also give you full control over water and nutrients — critical in a Mediterranean climate where summer temperatures regularly exceed 35 °C and drought stress can kill an in-ground plant within days.
For rental properties and hotels, container gardens offer an additional advantage: they are moveable and low-commitment. A set of terracotta pots planted with basil, cherry tomatoes, and trailing bougainvillea can dramatically improve the outdoor feel for guests, and they can be rearranged or replaced each season without any landscaping work.
Choosing the right containers
Container material matters more than aesthetics. Terracotta is traditional and breathable, which reduces root rot risk, but it dries out faster — a serious concern during a Greek July. Glazed ceramic retains moisture longer but is heavier and can crack after a cold winter. Plastic and fibreglass are lightweight and moisture-retentive, making them practical for rooftop terraces where weight limits apply. Whatever material you choose, drainage holes are non-negotiable; sitting water kills roots fast in summer heat.
Size is the other key variable. Shallow-rooted herbs such as basil, parsley, and oregano are comfortable in a 20 cm pot. Tomatoes, peppers, and aubergines need at least a 30–40 litre container to produce a meaningful harvest. When in doubt, go larger — a bigger pot holds more water, runs cooler, and forgives irregular watering far better than a small one.
5 steps to start your first container garden
- 1
Pick your location before you pick your plants
Walk your balcony or terrace at midday and note which spots receive full sun (6+ hours), partial sun (3–5 hours), and shade. Match your plant list to what that location actually delivers. Sun-loving crops like tomatoes, basil, and peppers must have full sun; shade-tolerant herbs like mint and parsley will accept partial sun. Choosing the wrong location is the most common reason beginner containers fail.
- 2
Use a quality potting mix, not garden soil
Garden soil compacts in pots, cuts off airflow to roots, and drains poorly. Buy a potting mix specifically labelled for containers — ideally one that contains perlite or pumice for drainage, which is especially important in the intense Greek heat. Fill the pot to within 3–4 cm of the rim to leave room for watering. If you are growing vegetables, mix in a slow-release granular fertiliser at planting time so plants have nutrients from the start.

Plant at the right spacing and depth
Crowding is the second most common beginner mistake. Each plant on the label shows a spacing recommendation — follow it, even though seedlings look small. In a container, overcrowding reduces airflow, invites fungal problems, and starves plants of nutrients. Depth matters too: plant at the same level the seedling was growing in its nursery pot, with the exception of tomatoes, which can be planted deeper to encourage stronger root development from the buried stem.

Water consistently and deeply
In Greek summer heat, containers dry out fast — sometimes within 24 hours for small pots in full sun. Push your finger 2–3 cm into the soil; if it feels dry at that depth, water thoroughly until it runs freely from the drainage holes. Shallow watering encourages weak surface roots. A simple drip-irrigation timer connected to a balcony tap is one of the best investments for a holiday property, ensuring plants survive the periods between guest stays without a dedicated caretaker.

Feed regularly and harvest often
Unlike in-ground plants that can draw on the wider soil ecosystem, container plants rely entirely on what you give them. After the first 4–6 weeks (when any slow-release fertiliser at planting has been exhausted), switch to a liquid fertiliser applied every one to two weeks during the growing season. For fruiting crops, use a potassium-rich feed; for leafy herbs, a balanced nitrogen formula works better. Harvest herbs and salad greens frequently — regular cutting encourages new growth and keeps plants productive throughout the long Greek growing season.

FAQ
- Which vegetables grow best in containers on a Greek balcony?
- Cherry tomatoes, sweet peppers, chillies, aubergines, courgettes (in large 40+ litre pots), lettuce, rocket, and climbing beans all perform well. Herbs are even easier: basil, oregano, thyme, rosemary, mint, and parsley thrive in containers and are especially suited to the Greek climate. Avoid crops that need a lot of horizontal space or deep root runs, such as pumpkins, full-size watermelons, or root vegetables like carrots unless you have very deep pots.
- How do I keep containers alive through the Greek summer without watering twice a day?
- Use the largest pots you can manage, as bigger volume holds more water and stays cooler. Mulch the top of the soil with a thin layer of gravel or wood chips to reduce evaporation. Group pots together so they shade one another. A drip-irrigation system with a battery-powered timer can be set to water at dawn and dusk automatically, which is the most effective solution for holiday rentals or properties left unattended.
- Can I reuse potting mix from last season?
- Yes, but with conditions. Remove old roots and debris, then refresh the mix by blending in about 30 percent new potting compost and a dose of slow-release fertiliser. After a season of watering, salts can build up in the mix and nutrients become depleted, so topping up is important. If a previous plant showed signs of disease or pest damage, discard that soil entirely and start with fresh mix to avoid carrying problems into the new season.
