SoLongFairWell Posted July 19, 2013 Report Share Posted July 19, 2013 As you can see from the photo my regia is having some difficulty producing new leaves. One blackened off (dry) and the other one looks like it will go that way. Any ideas? It's growing in full sun in my unheated greenhouse in sphagnum and perlite stood in water all the time.

SilentGuy Posted July 19, 2013 Report Share Posted July 19, 2013 What size pots? I keep mine standing in some water but they're also in tall pots, so the roots aren't standing in water. Quote Link to comment Share on other sites More sharing options...
SoLongFairWell Posted July 19, 2013 Author Report Share Posted July 19, 2013 I should add it's NOT the two old leaves at soil level. Quote Link to comment Share on other sites More sharing options...
SoLongFairWell Posted July 19, 2013 Author Report Share Posted July 19, 2013 Nothing special about my pot. I didn't have access to any deep pots when I got the plant. Quote Link to comment Share on other sites More sharing options...

SoLongFairWell Posted July 19, 2013 Author Report Share Posted July 19, 2013 Think I'll move the plant outdoors into a spot that gets a little less sun while the heatwave is still here. Quote Link to comment Share on other sites More sharing options...
gardenofeden Posted July 19, 2013 Report Share Posted July 19, 2013 Is it an established plant or quite newly potted? Newly potted plants are a bit sensitive, I pot mine very early spring to avoid the summer heat, remember regia is virtually an alpine plant!

SoLongFairWell Posted July 20, 2013 Author Report Share Posted July 20, 2013 It's been potted for about 7 weeks. I got it from Nigel when I was in the UK. Quote Link to comment Share on other sites More sharing options...
SoLongFairWell Posted July 20, 2013 Author Report Share Posted July 20, 2013 So is it best to always grow it outdoors in the summer? Quote Link to comment Share on other sites More sharing options...
FredG Posted July 20, 2013 Report Share Posted July 20, 2013 Mine have been getting 35 - 40C of late Quote Link to comment Share on other sites More sharing options...
SilentGuy Posted July 20, 2013 Report Share Posted July 20, 2013 Mine is outside in the heat and sun, but it's standing in water in a tall and wide pot. Not sure if my top dressing of crushed glass is helping the roots stay cooler. Quote Link to comment Share on other sites More sharing options...
North West Neps Posted July 20, 2013 Report Share Posted July 20, 2013 Richard, i remember buying my Regia just a few weeks before you bought yours. If it helps any, and i'm no expert, but mine is doing absolutely fine in a 9cm pot in which i planted it in a 50/50 peat and glass sand mix, standing in 1cm of water, on a south facing windowsill. The past 2 weeks have been constant sun with daytime temperatures in my flat (with all windows wide open) still hitting between 28 and 34 degrees lately, and my Regia is fine so far with no burnt tips.

SoLongFairWell Posted July 20, 2013 Author Report Share Posted July 20, 2013 (edited) So do you guys think I've done the right thing in moving it outside to a shadier location or would it be better off back in the greenouse in a different pot? Mine's roughly in a 9cm pot. I've not taken a ruler to it or anything. Edited July 20, 2013 by Richard Bunn Quote Link to comment Share on other sites More sharing options...
maxxima Posted July 22, 2013 Report Share Posted July 22, 2013 Richard mine does best when protected from direct light. However my climate is much hotter than yours and I protect almost all my plants from direct sun. Regia's outside in full sun but the sun is filtered through a thin curtain. It hasn't died back this year and 3 basals have come up. I'd take Fred's and gardenofeden's advice as I've seen their plants in photos and they are jaw-dropping.

SoLongFairWell Posted July 22, 2013 Author Report Share Posted July 22, 2013 Going through my collection last night doing some weeding I think I now know the cuprit. Provado. I had sprayed my plants about 10 days ago and had the feeling that the pesticide came out too wet. I think the mist action of the gun has gone a little caput, it was a little more like a squirt. So I think it's burn from that as I found some new growth on some of my Sarras (Juthatip Soper, alata and rubra) were effected quite a bit.

mattynatureboy44 Posted July 22, 2013 Report Share Posted July 22, 2013 If you spray provado in the day especially when it's hot it has this effect on most plants as I found out on some of my plants last year unfortunately, including a couple of D. regia. I think you are supposed to use it when your plants are well watered and in no sunlight it seems to burn some of the growth otherwise but the good news is the plants are all OK after a couple of weeks .

gardenofeden Posted July 22, 2013 Report Share Posted July 22, 2013 Drosera don't like provado sprayed on their leaves so that may well be the culprit. However I also have loads of root cuttings sprouted which also look like that which I think I'd down to hot weather plus inadequate roots. So a shady place for a whole till it gets established would be good. Quote Link to comment Share on other sites More sharing options...
Amar Posted July 23, 2013 Report Share Posted July 23, 2013 I also believe D. regia, if the pot is not very large, does not like its feet in water all the time. Quote Link to comment Share on other sites More sharing options...

SoLongFairWell Posted July 23, 2013 Author Report Share Posted July 23, 2013 What depth do you keep your water at Fred? Quote Link to comment Share on other sites More sharing options...
FredG Posted July 23, 2013 Report Share Posted July 23, 2013 The square trays in there are 2" deep so I suppose the average is about 1¼" (2cm) Quote Link to comment Share on other sites More sharing options...
