Russell Lupines at the Chelsea Flower ShowThe chattering amongst those in - the - know about lupines is that short , they ’ve become difficult to arise well . It ’s lawful , In 1997 , anthracnose begin showing up world - wide , in population of Lupines , reportedly due to the commercial-grade growing of Lupine species as a protein seed souce , worldwide . Anthracnose , is a fungus , spread by wet dripping on thymine foliage , or grime support . Whatever the real cause , if one wish to grow honor winning lupine , such as the Russell Lupine above , photographed at last years Chelsea Flower Show in London , one require to take precautions .
It ’s not surprising that most retailer who sell seeds , give way to cite this trouble . A problem that can be have the best by abode nurseryman if they take a few precautions which may seem elaborate , but necessary .
1 . ordain DESEASE FREE seminal fluid .
German seed supplier Jelitto , is the only source that I have it away of , but there may be others who can supply to the home nurseryman . You must get seed which has been heat - treated , and Jelitto has a patented Jelitto JET ® process which render their Lupine seed near devoid of Colletotrichum acutatum , or , Anthracnose . But , fire from other sources can not be ruled out.2 . employ A STERILIZED PEAT - FREE SOIL MIX
This is critical . rest home sterilization is comparatively easy , if you have an oven , some foil and time . OK….so what are a few worm in the All Clad ! This weekend , in the warming , I was able to dig up some soil from outside in the garden , and bake it at 400 Degrees F. for two hours , along with some incisive gravel . This , I mixed with some perlite to create my peat - free mix .
3 . USE STERILIZED POTS
unwashed mother wit here , I simply souse some ejaculate pots and trays in household clorine bleach and water system , 2 tablespoons per Imperial gallon ( as if I measure ! ) .
4 . SOAK SEED FOR 30 minutes at 131 deg . F ( 55 deg . C ) . to kill any existing spores . This may reduce your germination pace , but it will be worth it .
5 . PLANT SEEDS AND seek to KEEP SEEDLING FOLIAGE DRY . This is authoritative , since you want to stave off spray with a antimycotic agent , I would imagine . Although , I seek to do organic horticulture , I in person do n’t have a trouble with Fungicides . They are utilitarian if your plant are to be turn in a dampish nursery for the outpouring , or alfresco in a sloshed arena .
Other than that , it ’s easy ! Lupines are magnificent when develop well , but understanding the issue they can now have , will help you if you plan on adorn on some seed or plants at your local garden center . Do n’t expect to regain this info on the come packet or in the semen catalog from most seed retailers . Clearly , it will put people off .
