Water Rosemary every 10 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.
Rosemary prefers very bright light or direct sun. It needs as much light as you can give it, including several hours of direct sun. A south-facing windowsill or a sunny patio is ideal.
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 Rosemary about every two months 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.
Drought-tolerant once established. Let the top inch dry out before watering; overwatering is the most common mistake.
As a starting point, water Rosemary every 10 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 Rosemary problems come from watering on a fixed schedule rather than watering when the plant actually needs it.

Feed Rosemary about every two months 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.
Rosemary 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.
