Overview

With stunning blooms from mid-summer to early fall, sunflowers bring summer vibes to the garden like no other plant. Flowers come in many colors (yellow, orange, maroon, and more) but they are commonly bright yellow with dark brown centers anywhere from 4 to 12 inches in diameter! These iconic blooms are a beautiful addition to any garden.

Sunflowers have two distinct growing habits, depending on the variety:

Single-stem varieties produce one flower for every seed, though blooms can reach up to 12 inches in diameter. 

Branching varieties produce multiple smaller blooms per plant that branch off of the main stem. 

Conditions

Sunflowers prefer fertile, well-draining soil that’s loose and deep. Ensure it is high in organic matter, as sunflowers feed heavily. Sunflower stems can grow tall, so ideally find a sheltered spot out of danger of heavy winds to limit the risk of weather damage. For optimal blooms and large plants, provide full sun (6+ hours of direct sunlight per day). Note - sunflowers may shade parts of the garden because they are so tall. Plant them in the northernmost section of the garden to prevent them from shading your other plants. 

Planting

Plant sunflowers directly outdoors in the garden after all danger of last frost. Use our grow calendar tool to find specific planting dates for your region! Seeds germinate in 7-14 days.

Plant seeds ½" deep in groups of 3, and space the groups 12-24" apart, depending on the variety. Note - single stem varieties can be planted more closely together, around 6-12". Firm soil lightly, water and keep evenly moist. Thin to one seedling per group when seedlings have two sets of leaves.  

Pests and Disease

Remove plants after they are killed by frost in fall to avoid disease issues the following year.

Harvest

Sunflowers can be left in the garden through blooming or cut for flower arrangements shortly after bloom. To harvest the seeds, cut the heads off after the stalks are quite dry and flower heads begin to turn yellow and droop. Cut flower-heads with a foot of the stalk attached. Hang heads in a warm, dry, well-ventilated place so the seeds may fully ripen and dry.

Nothing is Chew Proof, but these do pretty well
My three 2-year-old Dutch Shepherds have killed every toy except their Kong balls. These octopus toys are hanging in there. My dogs are particularly driven by wiggling the appendages - They LOVE it. My Sheba who normally kills toys immediately has not yet destroyed her octopus. She's been holding it like a teddy bear, that is after she's worn out from throwing it around. I've thrown them in the washing machine and they come out great.

Not good for aggressive chewers
This product does not stand up to aggressive chewing. My bulldog had it for about an hour before the legs disappeared.

Cute donuts. Not destroyed (yet!)
These squeaky doughnuts are really cute. It’s a bonus that it comes with two. I didn’t realize that when I ordered. I have two dogs and now they won’t fight over a doughnut just kidding one dog is 14 and doesn’t play with toys anymore. The other one is six and loves toys but for some reason he’s not really into this one maybe this will change but for now he only goes after it if I throw it, I’ll update this review to comment on durability if and when he starts playing with the toy, but for now it’s very adorable because it’s just sitting on the floor. Update: he picked one up only because I put it in front of him to take the photo!
