In comparison to other plants, sunflowers need a lot of water. They need a minimum of 2 gallons due to their rapid growth. A week with 57 liters. They have more in their early stages of growth. Weak stems and other issues will be prevented by this. Let ‘s look in more detail.

Outside or inside, your sunflower will get water fairly frequently. While watering around the base is important, keep a spray bottle handy and spray a few times over the head of the sunflower. It helps to keep the head moist, wash away dust particles, and make sure the plant gets some direct water.

  4. Do n’t soak the ground so much that it becomes unstable for the roots.
  5. Ideally, you should water your sunflowers early in the morning and late in the evening.
  6. If you use a rose on your watering can or sprinkler on your hose, you risk washing away too much soil, and especially with young plants, as it is gentle on them.
  7. If the ground is still moist from the previous watering, do n’t water it.
  8. Do not water after the rain has stopped.
  9. If it forecasts rain, you should see it. It may not rain, but the occasional day without water will not harm your bird.
  10. If the base of the stem starts to show signs of rotting, then you should allow it to dry out and try and save it.
  11. If the leaves begin to turn brown, then you need to water. Slowly increase the water quantity to bring it back to life.
  12. Do n’t water the head after it has turned brown. You want the seeds to dry out.
  13. If growing in pots, make sure they have good drainage and do n’t sit in a puddle of water. Do n’t let the soil dry out to a cracking stage, keep the soil moist.
