Citrus propagation – one year progress report
Well, it’s been about a year since I started trying to propagate my grafted Citrus mitis plant from cuttings and seed so I reckon it’s time for an update.
To be honest, none of them are looking great at the moment:
In spite of being fed with citrus tonic both cuttings and seedling are showing sickly-looking pale yellow new growth rather than the fresh lime-green new growth that the parent plant produces.
I could only think that this is iron deficiency (chlorosis) brought on by my hard tap water, but if so, why does the parent plant not have a problem?
Then I remembered that this is the first time I’ve actually tried to grow Citrus mitis on its own roots: the parent plant is a specimen I grafted onto a rootstock I grew from an ordinary supermarket orange pip, so perhaps by pure dumb luck I grew a lime-tolerant plant. The cuttings and the seedling are both relying on their own roots and maybe the roots of Citrus mitis are not as lime-tolerant?
Anyway, I’ve treated them all with a sequestrene iron tonic and I’ll see what happens.
Growth-wise, none of them have exactly been romping away, but I suppose if there has been a nutrient deficiency that won’t have been helping.
Would I bother again? Probably not to be honest. It was a fun challenge but I found my grafted specimens from years back produced sizeable specimens much more quickly, though of course I have to factor in the year spent growing the rootstock from a pip to begin with(!)
I’ll keep going with these for the time being and see how they develop. I’m intending to put them outside for the summer and hope that that will give them a bit of a boost.
