Wow, the tree is beautiful and looks extremely healthy! Great job on this tree, do you have both A and B type flower varieties on this tree? Thanks for the update!

Thanks Simon, and yes this tree has sir prize (B), lamb hass and carmen hass.

That does look great!

I'm curious how big the main trunk was when you did the approach grafts. And how big were the seedlings you were grafting on? Did you wait until the approach graft healed before chopping off the seedling's top growth?

Socal, that is one beautiful avocado tree you gotten really nice growth on that multi-grafted baby! I've multi-grafted older trees my top working and has worked well. But really like multi-root stock approach I'll have to try that!

This is how my triple rootstocks avocado tree looks like now

blooming again

Fruits from Jan blooms

I've watched this tree grow over the last few months and the benefits of multiple rootstock is phenomenal.

Congratulations John, that is a very heathy avocado tree!
Meanwhile, my doublerootstocking avo single experiment failed, the small sprouts
that broke the tape didn't continue pushing and the scion eventually dried up, even though
both rootstocks are still alive. (I may try again later).

Last week, I started an approach graft -also my first- of a Fuerte seedling to a young Sir Prize,
I have doubt if this will succeed since the thickness of the Fuerte seedling is much skinnier compared to the Sir Prize tree, so I'll wait and see...

Socal10b, can you post some updates on your multiple rootstock avocado? Any additional info you can give regarding production and growth will be greatly appreciated. I am considering planting out several multiple rootstock avocados at my friends place. Thanks,

Simon

Well, almost 2 years later, my approach graft took - to my surprise! - , this is what it looks today:

This is how I started it in Summer 2016:

My tree gave a single fruit in 2015, didn't flower in 2016; some 15 fruits total in 2017 , now it is blooming. So, yes, I am hopeful that this approach grafting can help make this tree a regular annual bearing one instead of an alternate bearing variety...(which some had said).

Not sure of its impact on the growth though, since the tree would naturally grows on its own (without the additional approach graft), but I notice a "faster" growth on one Fuerte scion I placed on the upper trunk; that I had since topped off about 2 ft of it last week.

Hi simon,

I will post some pictures of my multi rootstocks avocado when I get home today. Carmen hass is out of control, needs to be pruned constantly and it has a lot of fruits too.

I have a double root planted out that is growing like crazy. I haven't grafted anything to it yet. I have been waiting to get my trellis installed for a little espalier action. I have some other double root plants in root pruning pots waiting to be grafted. They seem to be doing really well.

simon_grow · « **Reply #35 on:** March 01, 2018, 04:24:55 PM »

Sam, please keep us updated on your tree. The graft looks great and the additional rootstock looks like it’s grown so much. Hopefully production will pick up once your tree gets a little larger.

Socal10b, can’t wait to see the update.

Vernmented, are your double rootstock trees all seedling trees? Let’s see some pictures!

Simon

socal10b · « **Reply #36 on:** March 01, 2018, 11:13:39 PM »

Here you go Simon. My carmen hass is fully loaded with fruit and still out growing sir prize and lamb hass. Roostock has been buried in the soil.

socal10b · « **Reply #37 on:** March 01, 2018, 11:18:21 PM »

I grafted a GEM back in summer of 2015, it is a compact and slow grower. GEM has 6 rootstocks. I will let it carry fruits this year.

Planted it in the ground after it took

How deep did you bury the root crown? I have been experimenting with this and having good results. So far I have only done things that root easily like pomegranate, dragonfruit and figs. I am going to try Jackfruit and annonas next. I have been obsessed with this since I read this article a while back.

Just wanted to add my experience with a double rootstock Sharwil. I did something like a double stone graft with a double width Sharwil scion, and it has been growing well, but strangely -- short internode spacing, and now, just about 9 months after grafting, at a height of maybe 1.5 feet, it's flowering heavily. So it does seem to impart precocity and change the growth pattern.

simon_grow · « **Reply #40 on:** March 15, 2018, 12:39:06 PM »

Thanks for the info Barath! The more information we can gather the better we can advance our hobby to the next level. So far there has been a couple people that seem to have positive results with double rootstock avocados but i’m as interested in the failures as I am with the successes. Has anyone done a double rootstock avocado that has died or perhaps one of the seedlings died?

If Double rootstock Avocado are truely more dwarf or shorter in stature, more disease resistant(Phytopthora) , more precocious or less prone to alternate bearing, this can be game changing. Even if just one of these variables is achievable, that is an advancement we can be proud of.

I had a double rootstock avocado die when I did it with an approach graft. I had Mexicola and Zutano seedlings in a large pot together and approach grafted them. It did fine for a while, and then I grafted a Greengold scion on the top (which was the Zutano top). Eventually, though, the area just above the approach graft started showing weird growth restriction, almost like it got restricted by a tight string. Eventually it died.

Nice growth. I love the mulch pile.

Lory · « **Reply #45 on:** January 24, 2019, 05:18:03 PM »

Your trees are not lacking of mulch Josh

All your scions grafts are side veneer isn't it?

Vernmented · « **Reply #46 on:** January 24, 2019, 09:43:06 PM »

Lots of mulch but there is a giant biochar fueled amended mountain they are sitting on as well.

The Choquette and Lula were veneer grafts and the Dupuis has two cleft grafts.

Have you noticed any difference in growth enery and speed comparing the two grafting systems?

I haven’t noticed and difference. The things that I find really push avocados along is good drainage, rich soil and heavy mulch. Avocados also get rootbound in pots pretty bad. These were multirootstocked in Rootmaker pots before they went out. I direct sowed a seed by each one a couple months ago to inarch on for a third taprooted rootstock.

I work at a friends small hobby farm and I am experimenting by mounding an entire yard of bulk potting mix and direct sowing the rootstock seed to be field grafted. I am guessing that will work really well but time will tell.

Lory · « **Reply #49 on:** January 31, 2019, 04:39:17 AM »

I can't agree more about the three key factors good drainage, rich soil and heavy mulch Josh
