Growing in Pots, Balconies & Indoors

Basil (Ocimum) is a group name covering many cultivars, so whether a given one makes a good houseplant depends on the variety – some compact basils grow happily indoors, others prefer more light than a room provides. As a group they are excellent pot herbs for a balcony, patio or bright, sunny windowsill, where the strong, direct light keeps them compact and flavourful.

Quick Details

  • Container Size: 5-12 L (1.5-3 gal); some cultivars need a bigger pot
  • Indoor Suitability: Depends on the cultivar; most do best on a bright, sunny sill
  • Best Spot: Full sun to half shade; the sunniest balcony, patio or windowsill you have
  • Soil & Drainage: Well-aerated, organic-rich mix (potting mix or peat/coir with perlite or vermiculite); must drain freely
  • Watering in Pots: Keep the mix moist (not waterlogged) and let excess drain away; pots dry fast in heat

Indoors & On the Windowsill

  • Houseplant suitability: It varies by cultivar – some compact basils grow well indoors, so check the specific variety; most others prefer more light than a room’s interior offers.
  • Windowsill growing: A bright, sunny windowsill with direct light suits nearly all of them; pick a compact cultivar for the sill.
  • Overwintering indoors: Basil is tender, so in cold climates a big reason to pot it is to bring it inside before frost – keep it on a bright sill in the cold season to carry it over or extend the harvest.

On a Balcony or Patio

  • Light & warmth: Give it the sunniest, most sheltered corner. Walls and paving reflect heat, which basil enjoys, but that also dries pots quickly – check moisture daily in hot weather and water more on warm days.
  • Wind & practicalities: Shelter it from strong wind, which shreds soft leaves and dries the mix; make sure the pot drains freely and sits where run-off will not stain the floor.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: The grower suggests a 5-12 L (1.5-3 gal); some cultivars need a bigger pot container with strong drainage holes. Skip a standing-water saucer under the pot to avoid root rot; terracotta breathes and dries faster, while glazed or plastic pots hold moisture longer.
  • Potting mix: Use a well-aerated, organic-rich mix – potting compost, or peat/coir blended with perlite or vermiculite for drainage.
  • Feeding: Potted herbs need feeding more often than those in the ground, as nutrients leach out with each watering – a light, regular feed through the growing season keeps the leaves coming.
  • Repotting: Where it is kept as a perennial, the grower advises refreshing all or part of the mix about every two years; pot up if roots fill the container.

Bloom & Edible Flower Guide

Quick Details

  • Bloom Season: Summer into autumn
  • Time to First Bloom: Usually in the first summer once heat and long days arrive; grown as an annual in cool climates and as a tender perennial where it is frost-free
  • Flower Appearance: Small white or purple flowers (the colour varies with the type) carried in a slender spike at the stem tips
  • Edibility: Edible — basil flowers taste like a gentler version of the leaf and make a nice garnish, though pinching them off keeps the foliage tender

Detailed Blooming Overview

Basil flowers as summer warms and the days lengthen, sending up slender spikes of small flowers at the shoot tips. Once it turns to flower the plant slows its leaf production and the foliage loses some of its flavour, so most growers thin the bloom to keep the plant leafy — unless the aim is to attract pollinators, who love the flowers.

Flower Characteristics

  • Small flowers, white or purple depending on the variety, arranged in a slender terminal spike.
  • Open a few at a time from the base of the spike upward.
  • Lightly fragrant and a good nectar source for bees and other pollinators.

Bloom Care & Thinning

  • Thinning the bloom: Thin the flower spikes as they appear — it is better for the leaves, unless you are growing the plant to attract pollinators.
  • Pollination: Pollinated by bees and other pollinators.
  • If you let it bloom: Leave a few spikes for pollinators or to save seed, knowing leaf flavour will fade as the plant matures.

Bloom Health & Protection

  • Aphids: They favour the soft flowering tips — a spray of water or insecticidal soap, or a little neem oil, keeps them down.
