\"Scheda<\/figure>\n

Sweet marjoram<\/strong> (Origanum majorana<\/em>) is a herb well suited to the balcony: it grows in a pot of at least 4 L and needs 4\u20139 hours of direct sun a day. Below, the verified data and the practical notes for container growing.<\/p>\n

Cycle and habit<\/h2>\n

annual or biennial grown as a seasonal crop; herbaceous clump or small aromatic shrub<\/p>\n

In a pot it develops to roughly 40 cm tall and 20 cm wide. The exact final size depends on cultivar, climate and container \u2014 these figures are a reference, not a guarantee.<\/p>\n

Light<\/h2>\n

Sweet marjoram needs 4\u20139 hours of direct sun; acclimatise gradually.<\/p>\n

If your balcony does not reach the minimum hours, choose the sunniest micro-climate: a south-facing, unshaded spot. For the full picture on sun by plant family, read Light on the balcony: how many sun hours per family<\/a>.<\/p>\n

Temperature and season<\/h2>\n

Grow in mild conditions and time sowing or repotting for the local climate.<\/p>\n

It tolerates down to about 7 \u00b0C; below that, move it in or protect it from the coldest nights.<\/p>\n

Substrate and drainage<\/h2>\n

Use a structural peat-free mix with mature compost and 20\u201330% drainage material; keep holes clear.<\/p>\n

On a balcony the container is small and drains fast: keep the holes clear and empty the saucer after each watering. For what to put in the pot, read Substrate and drainage: what to put in the pot<\/a><\/p>\n

Watering<\/h2>\n

Let the surface layer dry slightly between waterings.<\/p>\n

Pot soil dries much faster than ground soil: check it every day, especially in the hot season, rather than on a fixed calendar. For the complete watering method, read Watering in containers: how much and when<\/a><\/p>\n

Nutrition<\/h2>\n

Feed lightly: excess nitrogen can cause weak growth or reduce flavour, flowers and nodulation.<\/p>\n

In a pot the available nutrients run out sooner than in open ground, so a light, regular feed is what matters \u2014 not large, infrequent doses.<\/p>\n

Sowing and transplanting<\/h2>\n

Sow or transplant in the stated season; avoid root stress, keep the crown at the same level and harden off for 5\u20137 days.<\/p>\n

When moving to the final container, go straight into a pot of at least 4 L and 18 cm deep, so you do not need to repot again soon.<\/p>\n

Spacing<\/h2>\n

Keep about 20 cm between plants: the right distance improves airflow and slows the spread of diseases.<\/p>\n

Harvest<\/h2>\n

Harvest or deadhead with clean tools when the useful part is well formed; do not remove more than one third of the canopy at once.<\/p>\n

Harvest in stages, taking only what is fully developed, so the plant keeps producing for longer.<\/p>\n
