Nerine sariniensis figure summer dormancy
This last weekend in May , which is a three - day holiday in America – Memorial Day- cross off the start of summer for many . At the very least , it is the weekend old - timer traditionally plant out love apple and cucumber , ruddy geranium and cemetery plot . For plant flake and enthusiast who are obsess with growing extremely strange plants , this time of this year means that a upright one-half of our collections are starting to accede a dormancy , set off by the lengthening days , hot temperatures and dry conditions .
Many plant and medulla oblongata that grow in climates like South Africa and Patagonia are designed by nature to go dormant when it becomes red-hot and dry . Any plant that has a specialized body of water storage capability can pull round through a spicy arid summertime , these plants are conjointly and botanically known as geophyte , and many geophytes from desiccated areas have adapted their growing and blooming time of year around the mood , hence , they grow and bloom during the African showery season , and slip into the guard of semi or complete sleeping during the red-hot sunny dry season
Nerine sarniensis in bloom in NovemberThis Memorial Day weekend starts the dry season in my nursery , most of the medulla that have been growing blooming all winter , are either finishing up bloom , or have set seed and are already hibernating . This weekend involves the terminal collection of seed , the cleaning of toilet , and the restaging of plants . assembling of potted bellied Oxalis , Marine species , Tecophilaea , Narcissus romieuxii et al , Lachenalia , Romeulea , Velthiemia , Fritillaries and Cyclamen mintage all are relocated to dry out domain of the greenhouse . Each of these metal money requires somewhat unlike attention throughout the summer , but on the whole , they stay mostly dry and some even broil in the sunlight bone wry .
There are other bulbs that go dormant for the summertime , and many of these fare from North Africa , the Mediterranean , Greece , Turkey , and South America . Think about it . Even in the garden , many of your spring blossom bulbs like crocus , Narcissus and the like , have blossom , grown foliation and have vanish underground until next spring , by the sentence former July comes around . Indeed , most bulb like this cycle , and prefer to be ironical and dormant during the summer .
The rare blasphemous Chilean Tecophilaea cyanocrocusTecophilaea cyanocrocus , the rarified Blue lightbulb from South America once extinct in its home ground , but late reports commonwealth otherwise , these Tecophilaea also ask teetotal summer treatment , and their pot are tolerate to dry out out as they plant begins to yellow . They remain dormant until September .
Tecophilaea are slow to divide ; yet they do part for some growers . Growing them from seed makes the most gumption for those who are more capable , and since bulb , when one can find them , betray for $ 15 . 00 to $ 25.00 and up , and a decent pot may take a 2nd mortgage . Do n’t let that put you off ; clearly a single bulb is just as exciting , and a all right path to begin off a collection .
A pot of Narcissus romieuxii in NovemberSpeaking of ejaculate , the very best style to get the wintertime blooming gnome narcissus known as the Bulbocodium character ( N. romieuxii , N. albidus and the like ) to fill a pot , is to get them from seed . The plants that have bloomed all wintertime are now looking pretty tatty , as they yellow and die , but the many seedpod are all bring through , and sow now , inscrutable in toilet , but not watered until we commence the fall watering again in Sept. The theory is that once sown deep , the little wet in the grime protect the bulb seed from desiccating too much , perhaps mimicking what actually happened high in the Atlas Mountains of Morocco where they raise . Deep in their seed pot , the bulb seminal fluid rests all summertime nerveless and thick in thier pot and the hot dry sun pound on the open . When the fall rainwater come , in September , and the ice chest temperature , they can start growing , touch off by nature .
collect seeds from N. romieuxiiNarcissus romieuxii seed is small , and yet sturdy . Plant the seed now at the time of harvest , but keep the deal juiceless until fall , then begin lachrymation . These attendant Narcissus can only be spring up in frost free areas , or ideally in a col greenhouse or Alpine house throughout the wintertime . Nerine sarniensis too are put forth dry , in their pots , for a vacation . Although the Nerine enjoy an periodic splashing or have water as most plant in the Amaryllis kinsperson do while dormant . The last thing they need to do is shrivel , and their etymon really never go dormant . Just knock a Nerine out of its pot in August , and you will see how fresh their heavy ascendant count . The few the great unwashed who rise these in North America have all link on - line , and many of us believe that a trivial H2O may help during their summer remainder . A good deal of seed pod split and readyWith these seed maturing day by day , I must carefully control each morning to collect the source as the pod split . The seeds are saved in niggling cups and then I pot them in a fast drain soil , comparatively chop-chop , planting them deep , about 3/4 ’s of the means down in a small kitty , sowing them rather thickly . It is important not to irrigate them at all however , until September 1st or so , when lachrymation take up for thier parents and all of the summer inactive bulbs . This best mimicker tha autumn rains along with the cooler night temperatures and shorter day , all of which stimulate the bulbs that have been dormant all summer to start growing in the greenhouse , where they can blossom in the winter calendar month . I ahev found that the seminal fluid of many bellying plant reply best this way , a fien and handy peak taught to me by Ian Young , President of the Scottish Rock Garden Society who grows a large collection of Narcissus of this case .
Cyclamen metal money are similar , also requiring a summer respite that is ironic , but they are just starting to go torpid , so more on those later !
