Alstroemeria – a moving tale(!)
Whenever I add a new plant to my collection I generally find it takes a few seasons to become properly acquainted with it, and my alstroemerias are no exception.
I’ve been growing the Planet series of alstroemerias, namely Cahors, Sirius, Uranus and Sedna, for only a couple of years, and I now know from experience that they are reasonably reliable as regards overwintering in my location, both in containers and in the ground (they haven’t been tested for prolonged periods of below -5C, but that is rare in this part of the world, thankfully!). I also know that they flower freely over a very long period from May right through to December in milder years, that they aren’t overly demanding when it comes to food and water, that their flowering stems need support of some kind and that they appear to be non-invasive.
What I didn’t know until this spring was how they respond to being dug up and moved, something which varies greatly between species, so I decided to experiment with my clump of Cahors which I’d planted quite close to Sirius and needed shifting along a bit.
I was in two minds as to when to do it: for many herbaceous plants it doesn’t really matter whether you lift them in autumn or spring, but given that in my garden all my alstroemerias insist on flowering way into December I decided spring was probably the better option. So, in late March I set to with a fork and spade, carefully digging up the clump and re-planting it in manured ground a foot or so away. Then I waited….and waited….and waited.
I have to say that by the end of April I was starting to think that I’d managed to kill it because, whilst all my other untouched plants were sprouting vigorous new shoots, Cahors was doing absolutely nothing. Nary a leaf nor stem. It wasn’t until mid May that I finally started to see signs of life, and even now there isn’t much to show for it:
Just 3 short shoots have emerged thus far compared to the dozen or so much taller ones that have come up from the untouched plants:
So I think what I’ve learnt here is that whilst they can definitely be lifted and divided, they do not particularly appreciate the disturbance and are probably best left to their own devices as much as possible, only requiring attention when they become over-congested.
I imagine that my clump of Cahors will re-establish itself fairly quickly and will ultimately benefit from having a bit more elbow room, but I shall know to leave it in peace for a good few years now!
