How To Cut Sunflowers and Keep Them Fresh Longer (tips 4-5)

Cutting Sunflowers:

  • Place the stems in cold water for at least 4 hours before arranging them in a vase. This will help keep the heads from drooping.
  • Trim off any brown, dry leaves.
  • Cut the stems to about 6 inches long.
  • Fill a vase with cold water and add 1 teaspoon of sugar for each quart of water. (This will keep flowers fresh longer.)

Keep Them Fresh Longer:

  • Store flowers in a glass container or vase with plenty of cold water, change the water every 2 days if they are blooming or every week if they are not blooming.
  • Keep flowers away from direct sunlight and heat sources like radiators and fireplaces.

Estimated Vase Life

5 to 8 days (with care listed above, this can be extended to up to 2 weeks)

Care Tip

Sunflowers need a lot of water, make sure you check the water level daily and replace with fresh water and more flower food if necessary. To ensure good water uptake cut stems diagonally under water upon arrival.

Arranging Tip

When the petals fade, separate them from the large discs and use the discs as an interesting touch in arrangements.

Help! Why Are My Sunflowers Drooping?

Reason 1: Too Much Shade

The sunflower wilting leaves can be due to too much shade. The plants need sunlight to grow, and if they do not get enough sunlight, they will start to wilt.

Too much shade is a problem for plants because it prevents them from getting the light that they need in order to grow properly.

This means that the plant will start to wilt because it does not have enough sunlight for photosynthesis.

Reason 2: Too Much Watering or Overwatering

There is one thing that will harm or kill your sunflowers – overwatering.

The problem with overwatering is that it causes the roots to rot and the plant will die.

But how do you know if your sunflower needs water or not?

The best way to tell is by looking at the soil. If it feels moist and cool, then you don’t need to water it yet. If it’s dry or hot, then you know that your sunflower needs water.

Reason 3: Not Enough Watering or Underwatering

Sunflowers need at least an inch of water per week in order to grow properly. However, if the soil is too wet, it can cause the plant’s roots to rot.

The best way to measure how much water your sunflower needs is by using a moisture meter or just by checking the color of your soil.

If you are unsure about how much water your sunflower needs, then you should ask your local nursery for help or advice.

IMPORTANT – If flowers wilt or droop prematurely, cut them short and place in slightly warm water. Both the cutting and water temperature will help revive the blooms.

If outside, strong canes or bamboo sticks will help support young bloomers by correcting the stem of the plant.
