Generally speaking, the best time to plant sunflowers is two weeks after the last frost in your area, when soil temperatures have risen to at least 50F.

Sunflower seeds can be stored for up to a year in a cool, dry place, but they will not germinate well if stored in the refrigerator.

If you plan to store seeds, make sure they are tightly sealed in plastic bags, and store them out of direct sunlight.

Should you soak sunflower seeds before planting?

You can give vegetable seeds a head start in the garden by soaking seeds before planting them. The extra water can help the seeds to grow quickly.

Do you plant sunflower seeds point up or down?

Place the sunflowers 1 to 2 inches deep, point-down, every 6 inches or so, and then cover them with a layer of mulch. If you want to plant the seeds directly into the soil, you’ll need to dig a hole about 6 to 8 inches in diameter and 2 to 3 feet deep.

The hole should be deep enough to allow the roots to grow through it, but not so deep that they can’t get out. If you dig too deeply, your seedlings won’t be able to get through the hole and they’ll die.

You can also use a garden trowel or a shovel to make a shallow hole, about 1/2 to 1 inch deep and 3 to 4 inches wide, that will allow your seeds to germinate. Make sure that the bottom of your hole is at least 3 inches from the top of any plants that may be growing in it.

This will help prevent root rot and other problems that can occur when roots get too close to the surface.

How do you start a sunflower from seed?

Each 3- to 4-inch pot contains three seeds. You can get the best drainage with a soilless planting media. It takes between 6 to 10 days to grow indoors. You can enjoy continuous blooms through the summer by planting seeds every couple of weeks.

Should I water sunflowers every day?

Sunflowers do not need daily water. The health of your sunflowers can be adversely affected by daily watering. They don’t do well in shady, wet conditions because they love the sun, as their name implies. Water your sunflowers 1–2 times per week to keep them happy and healthy.

How many sunflower seeds are in a hole?

When planting in containers, make sure to put any commercial compost up to half an inch from the top. You should make a hole about an inch deep with a pencil and drop in the compost after soaking the soil.

If you don’t have access to commercial compost, you can make your own compost by mixing 1/2 cup of peat moss with 2 cups of water in a large pot. Cover the pot with plastic wrap and let it sit for a couple of days.

When you’re ready to plant, fill the container with compost and place it in your garden.

How long do sunflowers take to grow from seed?

The annual sunflowers bloom from summer to autumn. Depending on the variety, they can take up to 18 weeks to flower. It’s a good idea to sow sunflower seed every couple of weeks so that you have a constant supply of cheerful blooms to enjoy in the garden.

Sunflower seeds can be purchased at most garden centers, or you can make your own at home by following the instructions below. If you don’t have access to a garden center, you may be able to find seeds at your local farmers’ market or online.
