Here’s how to have geraniums full of flowers: water them like this to keep them blooming

Geraniums are a garden favorite, known for their vibrant blooms and easy-going nature. However, getting your geraniums to produce flowers consistently throughout the growing season requires the right care—especially when it comes to watering. Proper watering is key to keeping your geraniums full of flowers. Here’s how to water them correctly to ensure they stay in bloom.

1. Understanding Geraniums’ Watering Needs

Geraniums are fairly drought-tolerant once established, but they still need consistent moisture to produce their best blooms. Understanding their watering needs is the first step to a flourishing plant.

  • Soil Moisture: Geraniums prefer well-draining soil that stays moist but not soggy. Overwatering can lead to root rot and other issues, while underwatering can cause the plants to become stressed, reducing their flower production.
  • Climate Considerations: In hotter climates, geraniums will need more frequent watering, while in cooler, more humid climates, less frequent watering is needed.

2. How to Water Geraniums for Maximum Blooms

Watering geraniums correctly involves a balance—keeping the soil consistently moist without overdoing it. Here’s how to do it:

  • Deep Watering: When you water your geraniums, water them deeply. This encourages the roots to grow deeper into the soil, making the plants more resilient to drought. Water until the soil is moist to a depth of about 6 inches.
  • Morning Watering: Water your geraniums in the morning. This gives the plants time to absorb the moisture they need before the heat of the day. It also allows any excess water on the leaves to evaporate, reducing the risk of fungal diseases.
  • Check the Soil: Before watering, check the soil moisture. Stick your finger about an inch into the soil. If it feels dry at that depth, it’s time to water. If it’s still moist, hold off and check again in a day or two.

3. Avoiding Common Watering Mistakes

Proper watering is crucial, but it’s also important to avoid common mistakes that can hinder your geraniums’ blooming potential:

  • Avoid Overwatering: Geraniums don’t like to sit in soggy soil. Overwatering can lead to root rot, a condition that can be fatal to the plant. If you notice yellowing leaves or wilting despite moist soil, you may be overwatering.
  • Water at the Base: Always water geraniums at the base of the plant, directly onto the soil. Avoid watering the leaves, as wet foliage can encourage fungal diseases like powdery mildew.
  • Consistent Watering: Geraniums thrive on consistent watering. Avoid letting the soil dry out completely between waterings, as this can stress the plant and reduce blooming.

4. Supplementary Care for More Blooms

In addition to proper watering, a few supplementary care tips can help you get the most blooms from your geraniums:

  • Fertilization: Feed your geraniums with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. This provides the nutrients they need for continuous blooming. A fertilizer high in phosphorus (the middle number on the fertilizer label) can encourage more blooms.
  • Deadheading: Regularly remove spent flowers to encourage the plant to produce more blooms. This process, known as deadheading, helps the plant direct its energy into creating new flowers instead of seeds.
  • Pruning: Prune leggy growth to keep your geraniums compact and full. This not only improves the plant’s shape but also encourages more blooming.

5. Dealing with Specific Conditions

Different growing conditions can affect how often you need to water your geraniums:

  • Container Plants: Geraniums grown in containers dry out more quickly than those in the ground. Check potted geraniums more frequently, especially during hot weather, and water when the top inch of soil feels dry.
  • In-Ground Plants: Geraniums planted in the ground may require less frequent watering, particularly if they’re in a well-mulched bed. However, be sure to water deeply when you do water.
  • Heat Waves: During extremely hot weather, your geraniums may need extra water to cope with the heat. Consider providing shade during the hottest part of the day or watering more frequently to keep them hydrated.

Conclusion

By understanding and meeting the watering needs of your geraniums, you can ensure they stay full of vibrant flowers all season long. Watering deeply, consistently, and at the right time of day, along with providing a few additional care measures, will keep your geraniums healthy and blooming beautifully. With just a little effort, you can enjoy a garden or patio bursting with color from your flourishing geraniums.
