Gardening
Dahlias are crank tuberous perennials . A heavy Robert Frost will kill off the foliage , but soaked , cold condition in ill run out dirt will cease off the tuber , the reservoir of next years growth . My ground is jolly sandy and barren draining , and I would probably get away with leaving the tuber in the ground , but I ’m not confident enough of that to risk all of my dahlias . I ’m leaving some of the bedding dahlias in the ground , but most I am going to overwinter . I did this for the first time last year . I lose a yoke of pieces of dangly genus Tuber to rot but nearly all made it through entire .
Once the foliage is frost - scorch , the first whole tone is to cautiously take away the tuber . I trim away the foliage leaving a 6 inch helping of stem .
I used a broad garden branching , pushing it in about 8 column inch from the stem and levering the tuber out . I figured this was far enough away to stave off damaging the tubers . A couple of the larger works call for a second or third levering from a different direction .
As Dahlia pinnata tubers all look pretty similar I label them as I removed them from the ground , just bond a plant recording label assault the neck opening . Once labelled I took them off to the shed to dry out off , leaving them in the shed for a couple of years , upside down on some newspaper .
When dry , I brush off the soil , leave the tubers as clean and dry as possible , pare off any of the fine ascendant .
They will be hibernating for the wintertime , the important thing is to forefend the tubers getting damp , or they will go soft and rot off . Last year I stash away mine in dry compost , in a cardboard box that I kept in the shed where it is wry and frost - free . This class I am using vermiculite in a couple of plastic tubs . I put a layer of vermiculite in the bottom of the box and placed the tubers halt side up .
I then covered them with more vermiculite , exit the tops of the stems break .
gumption or sawdust would work as well , I reckon . The benefit of vermiculite is that it will steep any extra moisture . It ’s also what I had handy .
That ’s it . I shall leave them be in the shed until later February , other March when I project to bring them into growth and take some cutting . More dahlias !
For those tubers left in the ground , I have covered with a blockheaded mulch of farewell and garden compost , a lifelike duvet . Fingers crossed , they ’ll be OK . I ’ve added a recording label so I do n’t vex or cut off any parts of the tuber when fiddling about in the border over the wintertime .
I ’ll be back soon with more generation mischief .
UPDATE 6 - 11 - 18 .
All of my tubers stored this mode dry out out and go ! My mistake was not to moisten them when arrange into the vermiculite , and I should have checked them every twosome of weeks to ensure they were n’t drying out . An periodic spritz with a hand atomiser would have been enough . So that ’s a bummer . On the plus side , all the tubers I get out in the ground were hunky-dory , all came back to life this spring . This winter I am leaving all of mine in the priming , with a thick duvet of folio mold or compost . This is safe to do as my ground is free - draining – it ’s getting miry that the genus Tuber do n’t like , rather than the coldness . You deliver the goods some , you lose some .
