Dahlia Hall of Fame, the very best Dahlias to grow as cut Flowers for Flower arranging, Weddings and Events
To accompany our Instagram Stories on ‘Overwintering Dahlia Tubers’ here are my top key points Rule #1 is keep your Dahlias dry while they hibernate We don’t wash our Dahlia tubers until the Spring as we find this just discourages the likelihood that they will not freeze or rot. Rule #2 gentle humidity and ventilation…
ts really important to give your plants a chance ‘toughen up’ or ‘Harden off’ before planting out in the garden.
Its not just the change in temperature, they also have to get acclimatised to, lower humidity and increased air movement.
We move our plants from the greenhouse or polytunnel outside but under cold frames for 7-10 days.
Then for another period we will remove the cold frames but still give the plants some wind protection. A wall, close to the home or for us the side of the greenhouse is ideal.
With the cold Spring of 2018 you may be a little behind with your seed sowing…
The good news is, they will soon catch up and many seeds such as Zinnia’s actually resent been sown too early.
After a quick germination, they quickly die off as they sit in cold damp soil…
April is ideal, the sky is bright, the sun is warm, lets get started!
You’ll need seed trays, pots, bottom trays, potting compost, vermiculite or horticultural grit, clear dome lids, and plant labels.
