Still time to sow sunflowers!

'Teddy Bear' sunflowers

“It’s June, and you’re suggesting I sow sunflowers?” You know what, I’ve even had them flowering well from sowing in July. OK, it was July 2, but still.

But there’s two things to keep in mind. Firstly, don’t put your faith in a June sowing of ‘Titan’, which can reach 3m, or ‘Kong’, which can grow even taller. These need an early sowing. Secondly, give them a good start, keep them growing strongly and never allow them to get dry. And there are also two approaches getting them going.

You can sow them outside, in the border or even in a container, where they’re going to flower. The advantages are that you don’t need any special equipment and they never suffer any root disturbance so grow steadily. The disadvantages are that you may have to plant them between other plants which soon overshadow them and that they feed the slugs.

I favour sowing individual seeds in 7.5cm pots of fresh new compost and keeping them in a cold greenhouse with the tomatoes – full ventilation. Or in a sunny and cosy place outside. Be sure to set mousetraps, I’ve already learned the hard way this season that mouse traps are essential.

When the the roots are emerging from the pot, plant them outside, stake them with a slender cane and water them in well with tomato feed in the water.

Whatever your approach, water them every week with tomato food and watch them grow – and then watch them flower. And the varieties to try? I tried it with ‘Solar Flash’ and ‘Teddy Bear’ but I’d say that ‘Choco Sun’, ‘Little Leo’,‘Santa Lucia’, and perhaps even ‘Garden Statement’ would be worth a try.

Take a look at all the Mr F sunflowers, and choose for yourself.
