What size pot does basil need? Bigger than you think

Basil is one of the hungriest, thirstiest kitchen herbs, and it is almost always sold in a pot that is far too small. As a quick answer: give one basil plant a container at least 8 inches (20 cm) wide and deep, roughly a 1 to 2 gallon pot. The bigger the pot, the more stable the roots and moisture, which is the single biggest fix for basil that wilts every day. For how basil compares to other herbs, this page sits alongside the main herb pot size chart.

Why basil needs a bigger pot

Basil grows fast and drinks heavily, so it builds a large root system quickly. In a small pot, the soil dries out within hours and the roots run out of room, which shows up as constant wilting and slow growth. A larger pot holds more water and buffers the swings, so the plant stays steady between waterings.

The right size, plant by plant

• One plant: 8 to 10 inches wide and deep (1 to 2 gallons) is ideal.
• Several plants: space them about 8 inches apart in a large trough rather than crowding them.
• Material: plastic or glazed pots retain moisture better than terracotta, which suits basil’s thirst. Best containers for herbs compares the trade-offs.

Pot size fixes most wilting

If your basil wilts daily, the pot is usually the cause before watering technique is. A larger container is the cleanest fix, after which the watering rhythm in how often to water basil becomes much easier to manage. For the full troubleshooting picture, see why is my basil wilting indoors?.

When to move basil to a bigger pot
