Caring for Your Sunflowers

Sunflowers are beautiful plants that can grow in many different locations, including your home. They do require a bit of attention, but they offer you a good amount of options and won’t take up much of your time. Keep reading for the basics about caring for your sunflowers.


Sunflowers have the ability to grow in many kinds of soils and can survive in even poor quality soils. Here is a general rule to keep in mind: the better the soil, the larger the sunflower. This includes the size of the flower pedals, the total height of the plant, etc. Therefore, if you are planning to grow very large sunflowers, some high-end organic fertilizer will work best for you. If you have poor soil, try some slow-acting granular fertilizer mixed in to help aid the growth of your sunflowers. Again, the quality of the soil is not as important, so simply make sure it is free of rocks, grass and weeds before you plant the seeds.


Keeping the right amount of moisture in the soil is a major part of keep your sunflowers healthy and growing strong. If the soil stays too moist for too long, it will be too weak to hold the large sunflowers up if the wind begins to blow (or other problems arise). The sunflowers enjoy the soil when it is deeply moist, but not drowned or kept deeply moist all the time. Keeping an eye on the moisture of the soil is most essential a couple weeks before and after the actual flowering.

Dealing with Pests

Although pests are a pain, there are some easy ways to discover when you are having an issue with them, and you can often solve the problem easily. Common pests the end up around sunflowers are maggots, sunflower beetles and cutworms. The key to maintaining pests in your sunflower garden, or any garden when it comes down to it, is to observe it very closely on a consistent basis for the telltale signs. If you seriously look closely at the leaves and the actual flower pedals, you will be able to see if they have been eaten by pests. You can also look closely at the seeds for any bore marks the pests might have left.

Growing Indoors

The key to growing your sunflower garden indoors is allowing them enough space to spread their roots to a healthy length. You should definitely consider moving your sunflowers outdoors once they grow to a decent size, but it’s up to you how large of a flower pot you would like to invest in. As sunflowers can grow up to 6 feet in 3 months, be ready to change the planter often. Make sure you are giving the flowers enough sunlight as well. Although sunflowers don’t require constant sunshine, you should have no problem providing them with enough if you plant them indoors.

If your flower is drooping, use a wooden stake as a stabilizer by simply sticking it into the soil next to the plant (and tying them together). If one is leaning against another, just remove the less healthy plant.
