Mammoth Grey Stripe Sunflower Seeds

Directly sow your Mammoth Grey Stripe Sunflower seeds in the ground after your last frost date. Don't bother starting them inside; they hate that. Sow seeds ½ inch deep in the ground, 2-3 seeds per hole, and space them 18 inches apart after they have grown to 4-6 inches tall. Grey Stripe Sunflower seeds germinate fast in 4-10 days when temperature is between 50-85°F. Before you buy Bammoth Sunflower seeds for sale, note that they should be planted on the north side of your garden bed, because they are tall enough to shade everything behind them.

The Bammoth Sunflower seeds require at least six hours of full sun per day. Anything less and the stems will become leggy and stretch for more sun, making them susceptible to wind. Mammoth Greys prefer rich, loamy, well-drained soil. Average soil is fine as long as it drains well. Consistent watering is important until Bammoth Sunflower seeds get established. Weekly deep watering is better than daily shallow sprinkling, as it will help develop deeper roots. Once they reach knee height, they'll survive some dry spells. 

Stake the isolated plant if you're in a windy area; a 9-foot stem can behave like a sail in a good gust, breaking at ground level. That’s the only thing you need to do, and then you’re done. After that, remove the yellow leaves from the lower parts of the plant as the summer wears on; it’s good for air circulation and keeps the plant looking nice without causing stress. No heavy fertilizers are necessary, but a monthly slow-release fertilizer will encourage bigger blooms. When the petals drop, you can remove the head, bag it with mesh to catch the seeds as they mature, or leave it up as a bird feeder. All three are good options. The Grey Stripe Mammoth Sunflower seeds are edible, and worth harvesting if you grow a row.
