Spring 2026 Grow-A-Long

Now we have moved into Spring and left late winter behind I have created a new page to keep sowing simple, everything below can se started now.

This Page is for what I am sowing, nice and simple, you can find the ‘Greenhouse Updates’ here!

Hold off sowing your China Asters for now, they need more light for best results and will be triggered into flowering late summer. There is more information on individual photoperiods in the Grow-A-Long video for each seed variety /plant.

Click the pictures below to go through to the Video Hub for each seed. I’ll add each seed video as I sow them. Don’t forget to catch up with the Late Winter Grow-A-Long first!

Cosmos started now is PERFECT!

Started too early will be forced into flowering before the plants have achieved good vegetative growth, but started too late they will grow too much and not flower until very late in the season.

This is all to do with photoperiods which can seem quite complicated but all you need to know is March to early April is ideal in terms of light levels to get over this. Hollyhocks and Zinnia’s are also light sensitive so for best results sow now.

Lots of questions on heat mats

For Sowing FROM the first weeks of April

Seeds I’m starting next week are Nictotiana, Panicum and Wrinkled Cress.

It’s still too early for China Asters. To achieve the big stocky plants I show you in my garden I wait for the days to get a little longer, ditto with the Orach otherwise I find they are finished before I’ve had a chance to use them, the deep colours suit the Dahlias better than the light bright flowers of high summer.

Quick from seed you can sow every few weeks until mid April, too hot and they will bolt.

I am not sowing yet but you can if you wish and I have put the links here ready for you and it’s still too early for the tender Pink Pokers which grow much faster than Statice anyway.

Limonium sinatum will keep growing into November if they are fresh!

Even for drying it’s a bit early…

Phlox if intended to go with the Dahlia’s to recreate my patio pot displays are also best sown now. If you have started already another round is a good idea now.

You can keep sowing until late April
