Hard Pruning a Schefflera

When someone at a bonsai workshop advises me to chop trees back to leafless stumps, I'm often reluctant to do it. Although I've had some success with trunk chops, most of the time I'd rather cut trees back to the lowest growth, wait for back budding, then cut back further. Progress is a little slower that way, but I prefer to err on the side of caution.

With some species that approach doesn't work though. When I prune Scheffleras they tend to grow back from the point at which they were cut, not lower down where I want new branches.

So when I decided that this little Schefflera needed pruning, drastic measures were called for.

November 2019 -  before pruning

Some of the newer members of my club were horrified when I told them my plans, but I knew what had to be done. A few quick cuts later I was left with this.

November 2019 - after pruning

Scheffleras are slow growers and now, four weeks later, there are only a few tiny buds starting to put in an appearance on the branches. I know that my little tree is doing okay, but looking at it still makes me nervous.

At the time it was chopped I discussed my plans for its after-care with another member of my club. I said I intended to return it to its home in my greenhouse. He felt it should go outside.

At the time his idea seemed a viable option as the weather was extremely dry, so I felt a bit foolish when I said I wanted to protect it from the possibility of excess rain. But I feel vindicated now because it's been raining almost continuously for nearly five days. Slow persistent rain which is showing no sign of abating. Grey skies have become the norm and I've almost forgotten what the sun looks like! That's not normal weather where I live, but it happens every now and then.

I've seen what damage that kind of weather can do to a tree in this state.

Years ago I defoliated a similar Schefflera. That was back in the days when I still tried to grow some of my trees indoors. Keeping it inside shouldn't have been a problem. Scheffleras are very tolerant.  I kept my big one in a very dark room for years before I realised the error of my ways and moved it outside. My problem was that I lost patience. When it was progressing too slowly on a sunny windowsill, I decided to move it outside.

As luck would have it, a few days later we were hit by the kind of weather we're experiencing now. Too much water for a tree without leaves! In a few days it was dead.

Had I left this one exposed to the elements, it would probably have died too.

Two Weeks Without Drainage

I can't believe it's been four months since my last post.

Okay, I guess the fact that it's winter in South Africa counts as an excuse of sorts because I haven't been working on my trees that much. Not even the last couple of weeks when I should have been busy repotting them as spring is definitely in the air. Unfortunately I've repotted very few, partly due to the fact that procrastination is one of my big weaknesses, but technology problems have played a big part too. I was unwilling to get my hands dirty while waiting for tech assistance that never arrived!

Just about the only time I've worked on my trees lately has been at workshops.

One of the trees I felt had to be repotted urgently was the fig truncheon cutting which I struggled to keep alive through a heatwave last summer. Two weeks ago it was just starting to get its first leaves so I took it to a club meeting where I could get some help lifting it out of the two pots it was living in.

I bought a few pots from the club's shop and quickly repotted the tree into one of them before the meeting started.

It's been sitting in the shade since then, looking reasonably happy, and I was planning to move it back into the sun in the next few days.

August 2019 - showing early spring growth

And then I made a discovery which forced me to change my plans.

Among the items I was packing for today's workshop were training pots for repotting some of my other trees. I was horrified to find that one of the larger pots I'd bought two weeks ago had no drainage holes. That brought the horrible realisation that the pot I'd planted my fig tree in might not have any holes either.

My fears were soon confirmed. My poor tree has spent the last two weeks in soggy soil. What's more once I removed it from the pot, I discovered that the soil was really smelly.

I've now moved the tree into a better pot with clean soil, but I'm very worried about the possibility of root rot. This tree may still be fat and ugly (though not as bad as when I first wrote about it) but it's not a tree I want to lose.

It's back in the shade for now, and I've been advised to water it with a fungicide (which I still have to buy) and hopefully that will help it to pull through. For now, however, I've got a few nervous weeks ahead of me.

I Should Have Known Better

"Cactus" as purchased

When I bought my so-called cactus (since identified as a Pachypodium Saundersii) in the spring of 2015 my decision was made despite some serious discouragement from my mother who didn't want a plant with dangerous thorns invading her personal space.

It wasn't long before I started to wonder whether I should have deferred to her better judgement. Although I knew exactly what I planned to do with my "tree", the prospect of actually doing the job filled me with dread and I kept putting it off as if hoping that the work would do itself.

Eventually in February I took the easy way out and took it to a workshop where the hardest part was done for me.

"Cactus" pruned and planted in bonsai pot - February 2016

By the time it was safely tied into its bonsai pot my doubts had intensified and I was already contemplating the possibility of selling it or if necessary putting it on my club's raffle table. But I still held on to the hope that in time I'd learn to love it, and even took inspiration from this comment from one of my Reddit readers: "Kind of looks like bonsai from another planet."

At that stage my attention turned to gathering information about the species and working out how I was going to keep it alive during the upcoming winter. Although our winters are relatively mild, I have to protect some of my more sensitive trees from cold winds and frost, but it sounded like this one would be more tricky than most.

Meanwhile I left my "cactus" in a shady spot to recover from the trauma of root pruning but, with so many other trees to care for, I didn't pay it as much attention as I should have. About a week ago I became aware that its leaves were starting to dry up and in the days that followed I became increasingly concerned that something had gone horribly wrong.

On Thursday I saw the man who ran the workshop at which it was repotted, so I told him what had happened. He suggested I remove it from the pot and let it dry out for a couple of days. I was reluctant to handle those thorns more than necessary and put off inspecting it further until today, when I discovered that the base of the trunk had become extremely soft, a sure sign of root rot. Clearly this was the effect of over-watering.

Dead cactus - March 2016

I've seen this happen to other people's baobabs, which is one of the reasons I've never bought one. In some cases their owners have been able to save the trees by cutting off the part which has rotted and treating what's left of their tree as a cutting. I decided to see if I could do the same with this succulent, but it proved to be a lost cause. It was too far gone.

So, in answer to the question "Can I bonsai a cactus?", which I posed in my earlier post, the best I can say is perhaps with the right treatment it can be done, but I won't be trying again.

In closing it's only fair to admit that although she's never grown bonsai, sometimes Mother does know best. I certainly wish I'd taken her advice and resisted the temptation to buy a plant I knew nothing about.
