When to grow See individual seed packets for details. What you need Choose a packet of sunflower seeds — remember to look to see how tall it might grow Gardening gloves A rake A trowel Plant label and pencil How to grow Sunflowers can be sown straight in to the ground where they are going to flower, so make sure the space you are going to sow is weed free, by using a trowel to remove the weeds.

Rake the soil to a fine tilth a fine crumbly texture and make some drills 12mm deep. Leave a 10cm space between each seed. Fill with compost then gently push the compost down to compact it and secure the seedling.

Water well and add your plant label. Position the pots in a warm, bright spot. Tip: be gentle when removing the seedlings from their cells to avoid causing damage to the plant or roots.

If needed, gently run a narrow, flat object such as a dinner knife or even a plant label, around the inside of the cell to loosen it. Once your plants have reached 30cm 12 inches in height, you can plant them in the garden or move them to a bigger pot.

Create a drill a shallow depression in the soil for each seed with a 10cm gap between each one; the drills should be about 12mm deep. Carefully place the seeds into the drill and cover with soil. Once the sunflowers become taller, use a cane to support the stems by loosely tying the stem to the cane with some string. This will help keep the stem strong and the plant will be encouraged to grow straight.

To pinch out sunflowers, remove the growing tip of the plant using your thumb and forefinger; this should be done once the plant has reached 20cm to 25cm 8 to 10 inches in height.

The plant should grow to 1. There are various varieties of sunflowers, and each one will grow at a different rate. On average, though, it takes between 80 and days for a plant to mature and develop seeds. Cucumbers are considered by many to be an essential addition to a summer salad, so why not try growing your own? If you want to There are many different types of lettuce and salad crops available for growing at home.

Runner beans, like peas, are far tastier when they are grown in the garden, compared to those you buy in the shops. I hope this has been helpful and a fascinating read to you as it has been for me to write.

I bimble about my garden enjoying the fruits of my labour and sometimes take for granted the marvels of mother nature. She nurtures the seeds I plant at the beginning of the spring, for a harvest by the late summer. Writing this has made me realise the awe I have for how my sunflowers grow.

The time it takes and the way they use every opportunity to get the best from their environment, without impacting on it. And at the end of their timeline they give back what their growth has produced.

When do sunflowers bloom? But This can vary for all the different varieties in the world and The condition you grow them in. No two sunflowers are the same, not even if the seeds come from the same plant. In fact, not all sunflowers are sunflowers! If you want to know when they will bloom in your part of the world then check out our table here.

How much does a sunflower grow in a week? Sunflowers are a very fast growing plant. Check the packet on your seeds to see how tall the sunflower is expected to grow.

Then to find an average of growth per month, divide that height over the period, allowing about a month at the end when it no longer grows or just focuses on blooming. So for example over a 5 month growing period from planting to the start of blooming, you can expect a 6 foot variety of sunflower to grow around inches cm per month.

Then divide approximately by 4 approx to arrive at the sunflower growth per week. What time of year do sunflowers bloom? The tall single giant headed varieties usually bloom towards late summer and last for 2 to 3 weeks. The smaller and multi headed varieties, perennials too, can start blooming at the beginning of summer and if deadheaded regularly they will keep flowering throughout the summer months.

Do I have to wait to plant til next spring? I am currently working on a project creating an interpretive kiosk talking about phenology and the timeline you have illustrated of the growth of sunflowers is a great illustration and would love to use it for the project I am currently working on.

Thank you Matthew. I would only ask that you add a citation, then feel free to use it. This is a wonderfully helpful article. My daughter wants to wed in a sunflower field — in April. We are test planting a range of sunflower varieties to track their days to bloom and decide when we will need to start them indoors to be ready for her wedding day April 17th I based the timeline article on sunflowers that grow to feet tall, such as the Giant Russian, Tall Single, and Titan, and in the ideal climate and growing condition.

The only solution I can think of to protect them and acclimatize them further when planting out, would be to use something like this tunnel. I hope all goes well and that you have a field of sunflowers blooming at the right time. Emmm, if the first 2 leaves turn their heads down and died, does it mean this one not developing well and will die soon?

It's cold here and I didn't have alot of room in the house so I put them in paper bags cut in pieces each and put them in the shed. The backs have turned black on some and some of the seeds have mold on them. Can they still be harvested and eaten?

Do I need to bring them in where it's warmer or is it too late? We would not advise eating the moldy seeds. Unfortunately, if the others were kept in the same bag, they may have mold spores on them despite looking alright.

Planted six seeds this spring. Five survived and now are from eight to ten feet tall. One of them has a head about ten inches in diameter and drooping over. What, if anything do I do with it? My first time for Sunflowers. What do I do with them this fall? We have been stationed in Germany for almost a year.

I decided to buy some bags of sunflower seeds for the birds and one of the seeds germinated in my flower bed. I left it alone to see if it would grow. It is now approximately 4 feet tall. The interesting thing is that it is one stalk with 3 flower heads on it. Is this a normal thing? One head is now opened, second is half opened and 3rd is just starting to open.

I can send a photo if you need to see it. Yes, this is normal! Many sunflower varieties produce more than one flower, while others typically the giant ones only produce one. Planted year old seeds. Plants instead of growing leaves on the main stock new arms with leaves and very small flowers grow. First time this has happened to me. Plants are six feet tall now, and very bushy, four feet wide.

Unless the main stem was somehow damaged…? Sunflowers will branch out if damaged. We got a small package of sunflowers in July to plant. Will they last until next year or should we go ahead and plant them now and try to retrieve some of the seeds for next year? Sunflower seeds will last until next spring without issue, as long as they are kept in a cool, dry place.

In most regions, this will fall between April and mid-July. In the south, this will probably occur in mid-March or early April. Sunflowers dislike having their roots disturbed, which is why we recommend direct-sowing instead of transplanting. Sunflowers grow best in locations with direct sunlight 6 to 8 hours per day ; they require long, hot summers to flower well.

Choose a location with well-draining soil. 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.

Sunflowers thrive in slightly acidic to somewhat alkaline soil pH 6. Sunflowers are heavy feeders, so the soil needs to be nutrient-rich with organic matter or composted aged manure. Or, work in a slow release granular fertilizer 8 inches deep into your soil. If possible, plant sunflowers in a spot that is sheltered from strong winds, perhaps along a fence or near a building.

Larger varieties may become top-heavy and a strong wind can be devastating. Before planting, decide whether or not you want to grow a fun sunflower tower. If you wish, you can plant multiple seeds and thin them to the strongest contenders when the plants are six inches tall. Give plants plenty of room, especially for low-growing varieties that will branch out. Make rows about 30 inches apart.

For very small varieties, plant closer together. A light application of fertilizer mixed in at planting time will encourage strong root growth to protect them from blowing over in the wind.
