Five Mistakes to Avoid Growing Giant Sunflowers from seed 

Absolutely, we have covered this in a video we took last week, but we are still waiting for the seeds to germinate before we can edit. Should be published in the next few weeks. Thanks for sharing your advice. Kind regards Simon

I'm sorry to hear that. I do have another sunflower video on my channel that may give some more tips, but in the meantime, I will wish you the very best of luck. Kind regards, Simon

Hi Andi and thanks very much for your supportive comment. Regarding cross pollinating, I don't think you can do much about that as you have no control over pollinating insects and the distances they travel. If you are trying to produce seed for record breaking sunflowers then there is probably no harm in hybridising a selection of suitable guant cultivars. If you want the seeds to grow as true to a particular parent then only grow that specific cultivar. It all depends on what you are trying to achieve. Simon

@@walkingtalkinggardeners I'm using them to create a quick privacy screen initially. I wanted layers of different heights. This property had a beautiful garden at one time. I intend to restore it to it's former glory. Somebody really liked sunflowers too. I want to keep up the tradition.

I feel your pain, the farmer put lambs in the field behind us and while we were away for a few days two of my sunflowers grew within reach if the top of the fence and the sheep eat the tops off. Aren't we a pair. Kind regards Simon

@@walkingtalkinggardeners We are a pair. I'm sorry.

Hi Mary and thanks for sharing your experience. I think I may have to steal this technique and see how it fares here. Kind regards, Simon

Hi Kim. I've not heard of that one here in the UK. I would be interested in how you get on with it. Simon

Hi Jimmy and thanks for your question. I would say yes it is, but if you already have the seed and you want to give it a go I would say why not otherwise you will have to wait until next spring. However I wouldn't sow in a pot I would direct sow in a site that receives full sun. Good luck. Simon

Sunflower seedlings and when in bloom can survive to minus 28 degrees. Zone 5b.

Meant, 28 degrees.

No problem with the plants, but I have a problem with a cat pooping on the barkchips before scraping the barkchips out onto the path! This happens several times everyday. Simon

You are very welcome, Bobby. Simon

This is possible, however you may also have been sold dodgy seeds! I had this issue last year. Simon

Indeed, all these fancy varieties come with a premium price. It shouldn't be so but that is how the industry is.
