What is the best way to grow sunflowers?
To grow sunflowers you need a sunny, sheltered spot and a good soil – add plenty of well-rotted manure or garden compost before planting, if you can. Protect the young plants from slugs and snails and water your sunflowers regularly. You may also need to stake them if they’re in an exposed position.
Are sunflowers hard to take care of?
Sunflowers aren’t picky but the soil can’t be too compact. They have long tap roots that need to stretch out; in preparing a bed, dig down 2 feet in depth and about 3 feet across. They’re not too fussy when it comes to soil pH either. Sunflowers thrive in slightly acidic to somewhat alkaline soil (pH 6.0 to 7.5).
Can sunflowers grow in pots?
The sunflowers that are low-growing, reaching somewhere between 12 inches and three feet tall, are ideal for containers. They don’t usually need any support, and you can grow one plant in a six-inch pot, or three in a gallon-size container.

How to Sow. Sow single stem, large- headed sunflowers as 3 seeds every 1’–2′ apart and ¼”–½” deep. Sow multi-stem sunflowers 2′ apart. Professional cut-flower growers reduce this spacing by half resulting in longer stems and smaller flowers, which are more desirable for bouquets.
Do sunflowers need to be staked?
While a few sunflower varieties do not need any staking, it is a good idea to support plants that grow over 3 feet tall or are multi-branched. Tie the plants loosely to stakes with lengths of cloth or other soft material as needed. Birds and squirrels can be a problem when seeds ripen and harvest time approaches.

The showy outer ray petals help attract the pollinators. Bees go from flower to flower within the disc, becoming covered with pollen.
Will sunflower grow if tops are eaten?
