If you want geraniums (Pelargonium) full of flowers, watering correctly is one of the most important factors—but it’s not the only one. Geraniums prefer a balance: enough water to stay healthy, but not constantly wet soil.
How to water geraniums for abundant blooms
- Water deeply, then let the soil dry slightly
- Water until excess moisture drains from the bottom of the pot.
- Wait until the top few centimeters (about 1 inch) of soil feel dry before watering again.
- Avoid frequent small sips of water
- Light daily watering can keep roots too wet and encourage weak growth or root problems.
- A thorough watering less often is usually better.
- Water at the base, not over the leaves and flowers
- Wet foliage can encourage fungal issues.
- Direct the water onto the soil around the roots.
- Adjust for weather
- Hot, sunny days: geraniums in pots may need more frequent watering.
- Cool, cloudy periods: they need less.
- Use well-draining soil and pots
- Make sure containers have drainage holes. Geraniums dislike sitting in water.
Extra tips for more flowers
- Give them several hours of sunlight daily.
- Remove faded flowers (“deadheading”) to encourage new blooms.
- Feed with a balanced flowering fertilizer during the growing season.
- Avoid too much nitrogen, which can produce lots of leaves but fewer flowers.
A thriving geranium usually has firm green leaves, many buds, and soil that alternates between slightly dry and well-watered—not constantly soggy.
