Post 189 Swamp cypress branch grafting

Summertime here means high temperatures and high humidity. If you grow your swampys in a shallow pan of water they are just 'as happy as' and produce the growth to show their appreciation. One of the interesting things they do is throw out 'adventitious' shoots which head for the sky like 'water shoots' that emerge from the base of a fast growing rose in season.
These can be very useful for either trunk thickening sacraficial growth or grafting for branch development as well.

In this post I've done some grafting on two swampys using both these adventitious shoots as well as hosted hairpin scions.

As is often the case, without apparently planning to do so, we sometimes develop our trees with branch gaps. Alternatley one's tastes change as perhaps have mine with more branches having more appeal than less. If the shoots don't come where you want them, then grafting is the easy answer.

I've posted about hairpin grafting previously where I've done them on figs.

 This is a picture of a small swampy cutting that has been bent into a hairpin ready for grafting.

It was done some time ago and is quite happy growing in that shape. As you can see the tissue has bulged on either side of the bend as the plant sought to overcome the tissue damage from the bend. In making the graft all the preparation that is required is to trim off these side bulges, exposing the callus and vascular tissues and inserting the hairpin into a suitably deep drilled hole in the trunk.

 On this tree you can see there are two hairpin grafts. On the top one on the upper right margin you can see the callus tissue is already integrating with the outer bark of the tree and the upper, outgoing section of the scion is already a larger diameter than the incoming, a sure sign of incorporation. On the lower one I've not yet removed the retaining wire but it is looking good.

 This is another picture of the lower graft and here you can see the relative sizes of the incoming and outgoing parts.

 On the other tree there are also two grafts but both from adventitious shoots from the same tree. This picture is from the front of the tree and you can see on the right a shoot that comes from lower in the tree towards the rear has been brought up and turned into a 90 degree hairpin graft. On the upper left is an approach graft done using a well advanced large diameter shoot from lower down in the rear of the tree also.
 

  In this picture from the rear you can see the approach graft of the upper branch. The branch next further down on the right is also another new one from a shoot that did come in the right place. So this tree will have three new branches developed in the 50 to 75% sector filling out the tree and better simulating reality.

Here again you can see both grafts from a side view.

These grafts were done less than 8 weeks ago and are already incorporating, reinforcing how very effective and quick the simple technique is in resolving structural flaws. The use of adventitious shoots shortcuts the development time for branch thickening after graft incorporation.
