Grow-A-Long Part 1 How to grow Ranunculus

Called the ‘Rose of Spring’, Ranunculus will provide gorgeous blooms throughout the start of the season, giving you an abundance of flowers long before the Roses wake up.

Autumn sown plants will need a protected growing space, either undercover in a greenhouse or polytunnel or in pots in a greenhouse. They will start blooming well before the last frosts. Frosts will damage the leaves and the flowering stems.

The protected growing environment will also give you very tall stems.

Grow-A-Long Part 1 How to grow Ranunculus

By early May, Autumn started corms will begin to shut down due to the very warm polytunnel temperatures. Plants have also been growing a very long time so in late Winter/early Spring I sow another round of corms.

This 2nd sowing will give me flowers in May and June, and depending on your local conditions, you might still be picking flowers in early July.

Reminder: Do not start corms December or JANUARY – light levels are too low and corms could rot in the cold.

Pre sprout them indoors it’s much to cold out in the Greenhouse and Corms may rot!

Anemones and Ranunculus Round 2

2nd March

Checking up on our Late Winter started Anemone and Ranunculus corms.

Its much too cold to start corms off in an unheated greenhouse so we have started them in a cool place indoors.

Due to the lack of space we made a change for late Winter and started off our corms all together in the same tray (but separated by colour/variety).

I tested the soil temperature and found it was around 14.8C. All the corms have sprouted and are ready now to be transplanted into their own trays.

Its important that you don’t leave this step too long, they will need moving on in 10-14 days after soaking and planting in the tray.

If you have any problems with your corms not waking up, check to see if the compost has dried out, it needs to be moist but not wet!
