Growing Wild Marjoram in a pot
For balcony, patio or terrace — Origanum vulgare
wild Marjoram grows well in a pot of at least Ø 30 cm (21 L capacity), in a position with full sun. Watering: 1-2x per week in summer, only when dry in winter.

Which pot?
Ø 30 cm
~ 21 L potting soil
A compact pot works well; herbs actually don't need excess soil.
Watering
1-2x per week
only when dry
Always use a pot with drainage holes. Water dries out faster in pots — or the plant drowns. Check weekly with your finger: only water when the top 2 cm of soil is dry.
Pot care
Wild marjoram is a low-maintenance herb once established, well suited to gardeners looking for a hands-off plant. Its low water needs make it ideal for dry, sunny spots. Water newly planted specimens regularly during their first growing season to help roots establish, but after that, watering is rarely necessary except during prolonged summer drought. Overwatering or poorly drained soil is far more likely to cause problems than dry conditions. Feeding is not required. Wild marjoram grows naturally on poor, free-draining soils, and too much fertility can lead to lush, floppy growth with less flavour and fragrance. If your soil is very poor or sandy, a light sprinkle of general-purpose fertiliser in spring won't harm, but it's seldom needed. Skip feeding altogether on average garden soil. This herb is fully hardy across temperate Europe (zone 4a–9b) and needs no winter protection. Leave the old stems standing until spring; they provide some shelter to the crown and look attractive when frosted. A mulch of grit or gravel around the base improves drainage on heavier soils and helps prevent winter wet, which is the main risk. Pests and diseases are uncommon. Aphids occasionally cluster on soft new growth in spring; a strong spray of water usually dislodges them. In very humid summers or on poorly drained sites, powdery mildew can appear on the leaves, though good air circulation and avoiding overhead watering reduce the risk. Slugs and snails generally leave the aromatic foliage alone. Wild marjoram self-seeds freely if you let the flowers go to seed, which can be a bonus or a nuisance depending on your garden style.
Pot-specific tip: add slow-release fertiliser pellets in March — potting soil exhausts much faster than open ground.
