What to Keep in Mind Before Planting Sunflowers

Before you plant sunflower seeds in your garden, there are some details you should consider first to ensure they grow healthy and beautiful.

Placement

As with any plant, sunflowers need to be grown in conditions that best replicate their natural environment. In a nutshell, sunflowers grow best in areas that receive at least six hours of direct sunlight per day, in loose and well-drained soil, and shielded against strong winds.

Ideal Weather

As for ideal planting time, the best time to plant sunflowers is during the spring, once you’re sure the frost won’t return. Specifically, soil temperature that sits around 70ºF – 85ºF is the optimal temperature for sunflower seed germination.

Type Of Sunflower

Sunflowers come in a beautiful array of colors, petal shapes, heights, and kinds of blooms. They can also be categorized according to growth habits, whether it grows one flower for a single stem or can branch out and grow multiple flowers in a single stock.

Maintenance

Sunflowers are both stunning and hardy. They’re drought-resistant and need minimal watering once their roots are established. However, they can’t be left unchecked and need additional protection against the wildlife they attract.

Risks

Sunflowers have their own set of disadvantages. Mainly, pests love feasting on sunflowers and this can be frustrating, Additionally, sunflowers are allelopathic, meaning they release a toxin that can negatively impact neighboring plants and inhibit their growth.

How to Plant Sunflowers

Growing a beautiful sunflower garden filled with multicolored or yellow blooms starts with a proper seeding procedure. You can learn all about how to grow sunflowers in detail with this article but if you want a summary, here are some tips for sunflowers:

Prepare your soil

Choose your flower bed carefully! Your sunflower should be planted in loose fertile and well-draining soil and away from areas that puddle. If you have compacted soil, you can till your garden bed or add several inches of compost and organic matter.

Bury and space your seeds

Once your soil is at the right temperature, you can plant your loose seeds. Bury them an inch deep and listen to your seed’s instructions to space them properly. This helps them grow their full size.

Generously water them as they germinate

To activate the growth process, be sure to generously water the soil. Until your sunflower has established a root system, water will help it grow faster and healthier.

Thin out your flowers

As they grow into seedlings, you’ll need to avoid stunting their growth by thinning your overcrowded sunflowers according to their recommended spacing. But only start thinning down once they have their true set of leaves.

Water weekly

When your flowers have established a root system, they’ll only need to be watered once a week. Try to water around their root system to avoid waterlogging them.

Sunflower Care and Maintenance Tips

Growing a sunflower garden is amazingly rewarding! Here are some tips to help make the most out of this experience in case you need it.

Plan for a continuous bloom

There are two ways to keep gardens in bloom all-season-long: through deadheading or succession planting.

Deadheading is a technique that restarts the flowering process by snipping off flower heads once it starts wilting. On the other hand, succession planting is the process of planting new seeds every two weeks so your garden reaches full bloom at different times.

Don’t feed the pests

Your biggest threat when growing sunflowers are squirrels, cutworms, moths, grasshoppers, and similar pests who treat sunflower gardens as buffets.

Using organic insecticides and fungicides can help drive away harmful insects. You can also repel squirrels with a mesh cage or by spraying your flowers with a spicy pepper solution. To make your own hot pepper spray, mix one bottle of Tabasco or similar hot pepper sauce with one gallon of water. You can add an egg to the mix to repel squirrels who gnaw tree barks.

Harvest before they bloom

If you want to bring the beauty of your sunflowers indoors, there’s an art to harvest them at the right time. You should harvest them while their petals are still cupped, right before they bloom. This will keep your floral arrangement alive and vibrant for much longer.
