Tree growing too quickly?

I have a spot in my yard where anything planted grows abnormally quickly.

Background:

When we moved into this home in 5/07 there was an enormous hemlock tree in the spot which for various reasons we had removed and the stump ground out. Later that year we planted a hydrangea in the general area and it grew huge and lanky very quickly. OK- I am new to gardening in this climate so maybe I just used the wrong plant.

The next spring ('08) we planted a Cotinus coggygria 'Royal Purple', Purple Smoke tree that I got for $1.99 on the Lowe's "neglected and nearly dead" rack in a one gallon pot- it can't have been eight inches tall. In the next year it grew to over ten FEET and was so top heavy with under-developed roots that it fell over numerous times. We kept propping it back up, staking- anything to get it upright.

By spring of '10 I had it with the falling over smoke tree and removed it. We took the opportunity to dig around and see if there was a buried troll or something causing all the super-growth, but found nothing unusual.

We planted a Cercis canadensis 'Forest Pansy' as pictured below-

The tree wasn't even as large as it appears because what looks like a thick trunk there is really an old rusted out farm fence stake.

You guessed it- it is growing way too fast IMO.

As the Forest Pansy was considerably more expensive (and more beautiful) than anything I have had over there previously, I want this tree to work.

It just seems so top heavy.

Same tree two years later-

I untied it from the stake a year ago (can't easily get the stake out) so it can move and develop strength, but I am scared that a branch is going to break or the whole thing topple over when a wrong wind goes by.

I have not pruned it because I am wary about regrowth coming back tenfold and further weighing it down.

That fence is six feet tall and the photos do not fully convey how heavy the canopy looks to me.

I'm a good pruner and know how to shape a tree and direct growth, but don't want to jump in if pruning it will encourage too much new growth like it does on many other trees.

I have never fed the first speck of fertilizer in this area.

I do water when it gets dry and try and take good care of my plants but don't do anything out of the ordinary.

This tree does seem to dry out very quickly which I would presume is because two year old roots can't keep up with the size of the canopy.

The Forest Pansy was from Rare Find- my Mom bought two from them the very same week and neither of hers are growing nearly as quickly, same town/ same general soil conditions.

So I have two questions-

1) Does this growth look too vigorous?

2) Should I reduce the weight by pruning?

Thx for any thoughts.

    I don't see anything wrong.

    Redbuds are capable of tremendous growth - I've seen a seedling turn in to a 10-foot tall blooming tree within 4 years! I wouldn't worry about it; be glad it's growing.

    Thanks.
    I only wonder because I have many other 'regular' redbuds on my property, both native and store bought, and none of them grow at a rate even remotely like this one.
    I'll try not to worry :)

    Redbuds can do 2+' a year easy when they are happy and this seems to be doing just that. It looks like yours has grown around 4' which is very good growth for 2 years, but not too far above the norm as least to me. Just very happy. You can also look at how much caliper that tree has gained as another indicator of how happy it is.

    Enjoy!

    what.. my teenager is growing too fast.. and its a problem????

    there is nothing wrong with creative pruning for shape and form ...

    its obviously well established.. so canopy reduction involved in pruning for shaping is fine with me ...

    look into ... carp.. blanked .. predestination.. subordination .. pruning.. help guys ??? ... lol . ..

    i shall presume you can find and ID the graft point.. and wont prune below such ...

    hard to go much further with a leafed out tree .. and viewing such on the WWW

    Here is a link that might be useful: i figured it out

    Thanks for that piece of terminology Ken.
    I have a crabapple that I need to look at closely this winter as it has a double leader situation going on that may need to be addressed.

    "Subordination pruning" is the one you want to investigate. The big word scares some folks off, but it's a simple enough concept: If you have co-dominant leaders, or even just a leader that you would like to behave better, shorten it up, don't remove it completely. By taking away its apical growing point, it will slow down, allowing the one you want to be dominant.....to be dominant. Always cut back to a side branch or branchlet, preferably one that is oriented such that it is growing out and away from center line of tree.

    I think the fallen needles from the old hemlock really enriched the soil creating a great acidic environment for plants like the hydrangea. Perhaps that could be part of the reason why things do so well there?

    That makes sense jqpublic.
    Although I like my theory about a troll being buried there, too. :)

    I have areas on my (newish) lot where the original "grade" remained and there was little/no backfill or compacting done. The clay soil there is deep and the trees in those small spots outgrow others by 1-2 feet per year.

    In one case, a bald cypress that is two years younger than a nearby dawn redwood outgrows it significantly (11' vs 6') and the bald cypress was also transplanted after it's first season.

    Additionally, even if your home is on sewer, at some point in the history of the property, that could have been a septic drain field, or compost heap or yard refuse burning/dumping spot.

    I do think the years of material from the old tree are the likely cause too though. I just like soil mystery :-)
