I have sown some dwarf sunflower seeds in seed trays - never grown these before so complete novice! they are coming through now and about an inch high - I can only grow them on in containers but no idea how many seedlings to one container - any advice greatly appreciated! Many thanks.
Every year I plan to grow sunflowers but always forget it until too late in the season. THIS YEAR I WILL DO IT. LOVE THE PLASTIC BOTTLE CLOCHES!!!!! THANKS SOOOOOOOOOOOOOOOOO MUCH!!
I have never grown sunflowers before so this will be an adventure. I love the idea of plastic bottle cloches. I will definitely try that. Thanks
Last year i grew sunflowers from seed, i had 12 plants. I planted them in the garden for my litlle son. We where proud of them and the morning after planting we went to say them was a googdbey indead!!!...: all 12 had been eaten by snails. They where about 10 cm high, so the snails had a good meal, there was really nothing left to see, just the soil. Now i have grown 16 plants [ 4 different ones] and i will sure use escar-go. [ it is bio, not dangerous for other animals.]
Kids have already planted a couple of sunflowers. Perhaps a bit early, but they are in fairly sheltered areas and about 2inches in height now. Going to plant some more, so we can use as cut flowers later on. Happy gardening!

In our village they have a competition for kids to see who can grow the largest sunflower head (not the tallest). A few years ago our daughter planted her sunflower on top of a hole filled with the previous year's manure where I had grown courgettes.

The plant didn't grow particularly tall - about 7 feet - but the flower head was HUGE, 21 inches across excluding petals.

My three children have challenged each other to a competition too. My friend has the allotment next to our so have given her three boys some seeds too. We have planted them all in various different places, including the garden so will see who comes out tops! I have promised the winner a prize. Feel it should be garden, flower related so any ideas appreciated?
put sunflower seeds out for the birds you all ways get a few unusual places

Slight problem - I may have planted my russian sunflowers a bit early (February) and they are all (22 of them) 30-50cm tall and growing 2-3.5 cm every day! I don't have space to keep 22 sunflowers indoors for another 2 months - I reckon they may be 2m+ by then! When is the earliest I can plant them out?


Could you start hardening them off outside for a while each day. (I know it's a pain bringing them in and out.) I'd pot them into bigger pots so that they are more sturdy and bring them back in if cold weather is forecast, and then out again when it's mild. And you could sow some more now, for insurance. Is there some way you can stack them?

Mine are 2 inches high and outside in pots doing fine

Liam, start hardening them off - in last year's long cold spring we had self-sown Russian Giants peeking up through the melting snow!!!  

Last week I sowed some outside directly into the bed where they are to grow. 

Hi I am a complete new starter at growing anything but wanted to teach my daughter life cycles of plants and where food comes from etc, so we are starting with sunflowers for our plants as I'm told they are easy to grow. We have planted as above only how will I know or at what frequency should I be watering them ?

Many thanks
I grew sunflowers last year for the very first time.
I started off at one seed per small plastic desert pot. I thought I may only have partial success so I planted over 20.
Well!!! They all grew magnificently, and I had to keep repotting them in larger pots(I don't have a garden) Some plants got to ten foot tall, and I ended up giving loads to my neighbours, our front doorsteps down our road was awash with sunflowers, and looked spectacular.
Going to grow some more this year, but not so many this time.

I've been growing them for many years. They're great for pollinating insects as well as birds and squirrels.


Excuse my ignorance but this is the first time I've grown sunflower from seed in many many years! What does the term 'hardening them off' mean? It sounds like it involves taking them out every day & then back in if cold. I have very limited mobility so would you suggest planting them directly into garden or starting them off in small pots then transplanting them outside when a certain height? My son is looking forward to it all! He has succefully grown the 2 seeds that he planted & they have reached 2 foot so far in one pot. I do have a mini greenhouse if that is an option? Thanks for any help offered!
As my Sunflowers grow taller they've taken a bit of a battering from the wind. I was advised to mound up and firm the soil around the stems to help keep them upright. It works well and has not caused any rot.

Hello, what is the best time to plant seeds for sunflowers in a greenhouse in the New Hampshire area? Thanks for your help! David


Hello David - I'm afraid that most of us are UK based - you'll probably do better asking the members of your local gardening club who will know the conditions in your area.

Good luck

Hi all I'd love to grow some sunflowers in my garden. Can I put seeds straight into the ground or should I start them off in a tray? When's the best time to plant the seeds, am I too late?
