Got a patch of the garden that needs a little late-season colour and wondering if some cornflower will fit the bill? But its July and everyone says to sow them in spring or autumn, so can I plant cornflowers in July? Let’s find out!
Can I Plant Cornflowers In July?
The one thing that will happen though is that their flowering period will be greatly reduced and effectively ended by the first frosts. Depending on when these arrive your cornflowers may only flower for a few short weeks.
If you have some seed to spare though you really have nothing to lose, and if the conditions are good cornflowers can grow really quickly and can flower in just a couple of months.
It really is a case of the sooner the better though and the earlier into July you can plant cornflowers the more chance you have of being successful.
How To Sow Cornflowers In July
I like to sow July seedlings into a root trainer and use multi-purpose compost. I like a root trainer over direct sowing as it gives me more control over the plant’s conditions.
Importantly it allows me to keep them well watered a lot easier than I could if they were in the ground, which is very important for seedlings growing at the hottest time of the year.
It also eliminates any weed competition and allows for the fastest growth of our little seedlings.
A root trainer also allows us to transplant the seedlings when they are bigger without causing any damage to the roots. This is very important for getting the quickest growth possible as any root damage can set the plant’s growth back by weeks.
Once the seedlings are well established you can move them out into their final position. Make sure the soil is rich and even give them an occasional feed to promote rapid growth.
If you follow all of these steps then you stand much more of a chance of getting a really good display out of July sown cornflowers.
