Start with the space, not the shopping list
Spend a day noticing the place where you want to grow. Look at it in the morning, around midday, and in the afternoon. A bright-looking balcony is not necessarily sunny all day, and a sunny corner may also be the windiest one. Write down what you observe before buying plants.
Measure the usable floor area and leave a comfortable route past the containers. For balconies, check your building’s rules and load limits before bringing in heavy pots. The weight of a filled, watered planter matters more than the weight of the empty container.
Give one crop a proper home
Pick something you actually like using: a small pot of herbs or a container of salad leaves can make a satisfying first project. Read the plant label or seed packet for mature size, spacing, light, and local planting conditions. Do not squeeze a large variety into a small pot just because the seedling fits.
Choose a container with drainage openings and a potting mix labelled for container use. The RHS lists herbs and salad crops among the options for container growing and stresses the importance of enough root space and a suitable growing medium.
Make a one-pot plan
- Location: record the light and wind you observed.
- Plant: write down the variety, not just “tomato” or “herb”.
- Container: check its usable internal dimensions and drainage.
- Water: decide how you will reach it, including when you are away.
- Review: take a photo after planting and another a week later.
Use our soil calculator before buying mix. Leave watering space below the rim and remember that a plant’s existing root ball also occupies volume. Treat the result as a shopping estimate, not a precise requirement.
Use your season, wherever you live
A calendar written for Britain will not describe the same growing season in Australia, and even two US cities can have very different conditions. Follow your local climate and the variety’s instructions instead of a universal “plant in April” rule. After your first container settles in, add another only if the routine feels manageable.
