Water Lettuce every 3 days as a baseline. Treat that as a reminder to check rather than a rule to follow blindly — push a finger an inch or two into the soil and water only if it feels dry at that depth.
Expect to water more often in warm, bright, or dry conditions, and noticeably less in winter when growth slows. A pot with drainage holes matters more than the exact interval: standing water is the most common way houseplants are lost.
Lettuce prefers bright, indirect light. It wants plenty of light without direct sun falling on the leaves — a spot near an east-facing window, or a few feet back from a bright south-facing one, works well.
If growth becomes stretched and leggy with long gaps between leaves, it is reaching for more light. Pale or bleached patches usually mean the opposite — too much direct sun.
Feed Lettuce every two weeks through the growing season using a balanced liquid fertilizer at half the strength on the label. Pause over winter — an unfed plant recovers far more easily than one with fertilizer burn.
Prefers cooler conditions — great for spring and autumn growing. Check soil every couple of days and keep it consistently moist.
As a starting point, water Lettuce every 3 days, then adjust to your own conditions. Check the soil first: push a finger an inch or two down and only water if it feels dry at that depth. Most Lettuce problems come from watering on a fixed schedule rather than watering when the plant actually needs it.
Lettuce prefers bright, indirect light. It wants plenty of light without direct sun falling on the leaves — a spot near an east-facing window, or a few feet back from a bright south-facing one, works well.
Feed Lettuce every two weeks during the active growing season (roughly spring through early autumn) with a balanced liquid fertilizer at half strength. Stop feeding in winter, when growth slows and unused nutrients build up in the soil.
Lettuce can be grown indoors or outdoors. Outdoors it will usually grow faster and need watering more often; indoors it needs the brightest spot you can offer.
