now that I have my 'Terra Nova' (my allotment ) I want to move
several DL's from my very overcrowded city garden to the new place.

The plants I want to move first are done blooming.
Does it make a difference (for the plants) whether I move them now or in, for instance, October?

Mayo

On a personal basis, I don't move plants in the heat of summer. When it's 100 degrees out, they are much too stressed as it is, trying to deal with heat, rain (or lack thereof), pressure from insects, etc.

I have many plants that need to be moved but I am going to wait until our temperatures moderate, which will be late fall/early winter months. I just don't feel safe moving plants in the dead of summer, but that's just me.

If it's a case of "have to", I will pot them up and set them in the shade until time to safely plant.

How hot does it get in The Hague during the next six weeks? I think you might be spared the kind of hot humid, heat that Judy has in Louisiana and the kind of hot, dry and usually windy heat I have in my part of Texas. If you only get temps that reach into the 80sF with cooler nights and reasonably regular rainfall, I think you'd be fine to move them now. Those would be temperatures and conditions that I'll be hoping for in October. That does assume you'll be able to provide some supplemental care if some days get too extreme. Just my thoughts on it. The sooner they get established, the better they should be at bloom time.

It was in the 90s in the shade in the UK today, I don't know if that extended to The Hague. What about moving them in about a month instead? That would give them more time to establish before winter than moving in October, but avoid the current hot weather if it applies there.

yesterday and today we had/ are having extremes of 85F during the day and 63F at night, but after today it will drop to the normal temps of 75F / 57F.
And, it being the Netherlands, regular rainshowers are to be expected..

I was thinking along the lines of Donald and Sue: the sooner I replant them, the more time they have to get settled..
My allotment is only a 10 minute drive away and I am there everyday to water and weed

Mayo

Good luck with your Terra Nova!
I don't think the temps there are too extreme. If they are done blooming why not.

I can't even imagine how it must be if it's 100F or more outside...
Even this 85F we're having is too hot!

The Hague is a coastal city, so our Winters are usually mild (and wet), our Springs cool (and wet) and our Summers pleasantly warm (and sometimes wet.. )
We normally have a soft breeze from the sea, so the one or two times a year it does get up to 85F we hang in there and hope it passes soon


Mayo

we easily reach 95F (35C) in summer. Poor breeze, high humidity and long dry periods!

poor you!

The Netherlands are situated along the North Sea and we have the advantage of the North Atlantic Gulfstream (which crosses from America to Europe at some point) going from the Spain to the Arctic Ocean along our coast.

I think you are.. what?.. 200 km from the coast? And you have the mountain at your back as well to keep the warmth in place


Mayo

Weare really close to some small mountain (pre-Alps) like you open the window and see the mountain. It's not a good place, these mountains cover sun (and stars, too, and we like to observe stars and planets), bring a lot of clouds and rain and then stop breeze. Not realy the ideal place!

Your extremes sound wonderful to me. I'll be really lucky to see those kinds of temps even in the early part of October. Your normal temps would send me running for a jacket . There is no such thing as 'regular rainshowers' in my part of the world. It seems those rarely occur in moderation and too often the gaps between are far too long. Under your conditions, I'd be moving the plants if it were me.

ah, the reply I was hoping for! Thank you, Donald

I'll wait until this 'heat wave' is over (it may not be too hot for the plants, but it sure is for me! ), but Friday I'll start moving some plants!



Mayo

Good luck! I sure hope it works out well since I encouraged it .

Mayo, even if it wasn't too hot for you it would be a good idea to wait a few days because in hot weather the plants need to take up more water. Dug ones will lose much of their root system no matter how careful you are unless they are small so can't support the same amount of leaf. You probably already know this, but they will recover more quickly if you shorten the leaves because then they don't need as many roots. If any have scapes they will likely still flower if you cut back the leaves to reduce the stress of moving. If the weather is cool, cloudy and damp you may need to cut back less than if the hot sunny weather comes back.

If you can leave (and move) as much of the dirt around the roots as possible when moving them, that might prevent any major transplant shock.

We have had temps in the 90's last several days with only one downpour of rain which helped a lot really. I have 2 clumps i want to separate and line out for next year but am waiting for this heat to subside. You said lows around 65, tonights low supposed to be 80 here. Unusual for us but not unheard of. Sounds like you have great Daylily weather for the most part. Today i watched great morning blooms get pounded by the heat and seemed to have melted them by late afternoon. The only thing i can stand to do is water them because the humidity is so high it just zaps ones strength.
Good luck on your move and hope you enjoy.
Donald i really feel for you in Texas. Growing anything sounds like a challenge. My hats off to you for accepting that challenge because no matter where you call home, there is no place like it.

to recap:
I've moved several big and small clumps from my home garden to my allotment and they all did perfect:
no yellowing or even drooping leaves at all!

Thanks all for your input

Mayo

Congrats on the successful move!
