Benefits of Cutting Off Sunflowers Heads

Sunflowers offer a variety of benefits, both for the gardener and the environment. One benefit of cutting off sunflower heads is that it encourages new growth.

Another benefit of cutting sunflower heads is that it helps prevent disease. Once a sunflower head has been cut off, it can no longer spread diseases to other parts of the plant or to other plants in the garden. This is especially important if you have had problems with diseases in your sunflower patch in the past.

Finally, cutting off sunflower heads can also help attract birds to your garden.
