The tropicals front of the greenhouse go on to age in the late summer heat of last week . I think Fergus can smell the genus Brugmansia . Although the heat and humidity of high - summer in New England efflorescence around the middle of August , the first cold fronts from Canada are also introducing cooler nights after wild thunderstorms . These cool temps might mean the end of summer for most nurseryman , but for me , it simply signals a chemise in plant material , for as summertime - blossom plant get to mature or go dormant with the temperature switching , and day - length shift , an entire serial of collection are commence to put forward into bodily function , being trigger by the same environmenta changes . Cyclamen species in the greenhouse are even beginning to boom earlier than normal . Here , a sand dip , where I keep a ingathering of many Cyclamen species , shows that even one C. hederifolium has even thown out a prime a snatch early . Last year , I had a disasterous answer from repot by Cyclamen collection in July , losing many of my metal money since I made the error of treating them like my other summer - inactive electric light , and let them go ironical . But not unlike some of the Amaryllis relatives from South Africa , the Nerine , which I used to let go pearl - dry and ‘ bake ’ in the summertime on mellow benches in the greenhouse , I now keep a little moisture available via some damp grit below , or with a spritz of water system once or twice during the summer calendar month .
This is critical for Cyclamen graecum , according to expert , and buddy John Lonsdale , who now populate and grows many rare plant collections in his Pennsylvania garden , Edgewood . ( Visit his site , it is spectacular – I ’d render a connection here , but having job since I am on a Mac , and Mac ’s Safari internet browser does n’t work well with this Blogger computer software which also is my excuse for spelling fault ! ) . John , whom I visited last downfall just when his Cyclamen where in peak efflorescence , told be that C. graecum prefer to stick around a little damp , peculiarly thier ‘ feet ’ during the summertime . So this year , I did not repot any Cyclamen , until last workweek , and at that , I just carefully slipped the rootballs into new pots , without disturbing the soil too much . I noticed that the graecum all had broad roots systems than ran out of the drainage hole in the hatful , and down into the damp sand , which remain damp because of the broken greenhouse trash from the summer , so rainfall fall on all the cyclamen in bantam amounts – in all likelihood perfect , since many I can see , are starting to send up new growth , and I only lost one through the summer . I will start watering deeping in a couple weeks , around September one , and we will see what fall out then ! I can recount already that the C. graecum have bud , as do the C. africanum , a more tender species from Persia .
Cyclamen graecum , the genus Tuber shew not only new growth beneath the thick layer of grit I keep on top of the genus Tuber , but it show the sizing of the tuber , and that it is firmly stock-still in the soil through - out the summertime . Much like my Nerine sarniensis , although the lightbulb seem dormant through the summer , below territory , the root are quite live , and in reality making substantial growth , in search of a little wet perhaps , to make it through the summertime heat .
The fall and winter - blooming narcissus also have use up a yr off from repotting , in an experiment to see if this will make a difference , and because I am too busy to do anything more than re - topdress with crushed rock , and to clean house - up the dope and relable . I motivate the collection into the Alpine house for the summer , so that they can really broil well , and because the broken glassful in the nursery was appropriate too much rain to fall on the pots .
