Variegated maidenhair fern update

A few years ago I bought a variegated maidenhair fern (Adiantum raddianum 'Variegata') and wrote a blog post about it.  

My variegated maidenhair fern did poorly.  I had it in a self-watering pot that was not designed well.  I normally grow maidenhair ferns in self watering pots and they usually work well, but this one functioned more like a pot without a drainage hole.  My fern went down hill badly until I repotted it and changed some of the soil.

My fern grew ok from here, getting larger and stronger.  The fern reached a rather large size and had long graceful variegated green and white fronds.

Then I had to move it to a different spot.  Maidenhair ferns do not handle direct sunlight, it burns them.  Variegated maidenhair ferns are even less able to tolerate direct sunlight.  Maidenhair ferns don't cope with no light, variegated ones even less so.  

Variegated maidenhair ferns can be a bit precious, but they are worth the effort.

Maidenhair ferns need bright shade, they thrive with a little direct sunlight early in the morning.  Contrary to what you have been told, maidenhair ferns do not cope with low light.  If the light is too low they slowly die.  

This fern is so beautiful that I really want it growing inside the house where I can see it.  Unfortunately, my variegated maidenhair fern did not get enough light in the spot I chose for it.  It declined again.  I tried moving it a little closer to the light, where it struggled to survive.  After some time of declining it only had one single frond!

I have a sheltered spot outside where I grow some maidenhair ferns and other delicate plants.  It is perfect for them.  They get a little direct sun at sunrise, then bright shade for the rest of the day.  

I don't want my variegated maidenhair fern to die, so I moved it outside.  I won't see it as much out there, but I sit out there on warm days and drink coffee so will still get to see it.  

Some of my ferns

Maidenhair ferns can bounce back quickly if they have enough stored energy, but my little fern had depleted its energy over a long time inside the house where it did not get enough bright light, so I was not sure if it could survive.

The fern immediately started producing new tiny fronds.  This filled me with hope that my fern would survive.  These new fronds were almost immediately eaten by slugs or snails.  

My fern still only had the one frond, only now it had used some of its stored energy to produce more fronds that had been eaten.  To make matters worse, the remaining frond was being damaged by the wind.  

This was not good.

I don't use much snail poison, I don't tend to use it ever, but figured this was probably the one time that I should use it.  I bought one that is iron based, and put a little on the soil near my variegated maiden hair fern.  

Apparently this iron based snail bait kills slugs and snails then breaks down and does not leave toxic residues.  The ferns are up on the deck so the chances of a bluetongue lizard eating it (or a snail getting down to them after injesting it) is low.  I am still not keen on using poison, so I only used a tiny bit.

I don't like using poisons, but there is a time and a place for them.  I don't want to lose my fern.  It took years to track one down and it was not cheap.  If this one died I may never find another.

The plant is uneven for now while it builds strength

Slowly, this plant produced more fronds.  At first they were tiny.  Some were damaged by wind or heat, but none were touched by slugs and snails.  

Over time my variegated maidenhair fern produced more fronds.  At first they were very small fronds, then the next ones were slightly larger, and the next ones larger again.  This is all a good sign.

The variegated maidenhair fern is now reasonable sized and starting to look healthy.  

The fronds are about half as long as they used to be, but they are getting larger as the plant gets stronger.  The plant also has a decent number of fronds now, and looks healthy enough to bounce back if it gets damaged.

Young fronds of maidenhair ferns are light green, and the variegation can be difficult to notice.  As the frond ages it turns darker green, and the white variegation really stands out.  

I have heard that some variegated maidenhair ferns have some non-variegated fronds, but so far mine has not done this.  All of the fronds have at least some variegation.

Normally I would rotate the pot a quarter turn each week so the growth is more even.  As my little fern had such little energy I decided not to do this yet.  I decided to let it orientate its fronds to collect as much light as they could and allow the plant to become stronger.  

Once my fern is a little stronger I will probably start to rotate it each week and slowly even out the growth.

There appear to be a few plants in the pot.  In spring if things are still going well I may attempt to divide this so I have a few of them.  If it doesn't look strong enough, I will give it another year or so before trying to divide it.  

For now though I plan to allow the plant to do whatever it needs to do so it can gain back its strength.

You probably have also noticed that I left the old dead fronds on the plant.  Normally I would try to remove them so the plant looks nicer.  

My variegated maidenhair fern was very weak, and it is growing outside where it gets hot wind in summer and cold winds over winter.  I figured the dead fronds would help to insulate it a little, slightly reduce water loss, and help to block the wind ever so slightly.  For these reasons I have left them on for now. 

I will probably leave it like this with the dead fronds until spring.  If everything is still going well in spring I will remove the dead fronds.

I like maidenhair ferns, and I think the variegated form is beautiful.  I am glad my maidenhair fern has survived.
