Just wanted to ask if it's safe for me to leave my dahlia outside now. Its in a container, about a foot and half tall.
Depends whether we are going to get anymore frosts. Where I am, we can still get frosts up until end of May / first week of June.
As doc says - it depends where you are. Frost can still appear in the next few weeks in many parts of the country, and will affect any soft new growth. It also depends on the variety - some are tougher than others. You could certainly harden it off a bit by putting it outside for an hour or two each day when it's favourable though, and building that time up over the next few weeks.
I'm in Essex and im planting mine out today.
In Stoke-on-Trent...mine have been out for a couple of weeks now.
In Scotland and still tucked up in the greenhouse!
near south downs and sussex coast but they dont go out till beggining of June.
I too am on the south coast mine are out the greenhouse but still in pots in a sheltered area and I will plant them out into their final positions at the end of the month. They are all over a ft tall apart from a few late bargain buys which only have a couple of inches growth.
I'm in the West Midlands and leave my dahlia's in the ground. I have one that started to show weeks ago, it's always early and it survived the frosts of a couple of weeks ago. The others are just starting to emerge.
Thanks for your replies. I am in London, so hopefully no more frost. Will start to put them outside couple hours each day and then in final position end of month. Thanks
If you are in London, I am sure they will be fine outside now.
Location is so important in giving horticultural advice.
