Type 'A' & 'B' Avocados on One (1) Tree | Before & After | GRAFTING STRESS TEST | Approach Graft

[Music] hi my name is Charles Malky biologist and plant expert with ivory organics where we grow cool plants and today we're going to be top working or pretty much grafting onto a dwarf avocado tree here in Los Angeles if you take a look behind me right here is that dwarf tree which measures about 20 to 25 feet a standard avocado naturally can grow about 30 to 40 feet and our goal is to basically improve the genetics of this tree as the owner doesn't like the flavor of his on average annual yield of about 30 avocados which is just not enough fruit as well so the goal is to graft on something more productive and more delicious and what better avocado than the Hass avocado so we're gonna be planting or grafting on to this particular dwarf avocado the Hass avocado as well as we're going to be also grafting on a forte which is a type B avocado so we're gonna have both the Taiping type B avocado growing onto one root stock I'll share with you more as we continue forward but let me give you a quick look at what the structure of the tree is check this out so here's the top of the tree as we're coming a little closer you can see all of the flowers as it's getting ready to bloom or here the first week of March and if we come in a little closer here's the trunk of the tree that basically comes up into a wishbone structure that then goes up and now so here we are about 15 minutes later and I hope some of you guys remember that video we published about two years ago about that fig tree that we it was about 15 to 20 feet tall producing beautiful delicious figs but we wanted to introduce about another five additional figs to that tree and we did it you know to basically introduce hopefully some more superior qualities of figs on to that particular root stock what we're doing here again is we're basically trying to increase yields and the goal is to also improve improve the quality of fruit as you can see there see there's that avocado behind me that we've now pruned down to about three maybe three and a half feet off the ground and now we're gonna begin the the grafting project and you can see behind me here are all the branches from that dwarf avocado tree so let's get started so here we want to check this out right here is the forte avocado we basically peeled half the bar back from the forte on the side that would be connected to the root stock and then we open basically a V opening onto the root stock and we basically press that in as tight as we can and here we are seedling grafted at this point with the fried avocado that's now connected to this root stock so we're going to basically take this Scion wood of the desired for attainable kado and here on this side we've got the next sound wood and above it let's take a look we've got this Hass avocado and seedling grafted at this point with the Hass avocado and then here's the Hass avocado grafted on to and bound in place you can see it's not even growing yet but all the life that's in this root stocking that this entire root system is going to support this 14 on this side and the hosta on that side and now we've got to type B in our type-a avocado they'll cross pollinate one another and you can see it's all resting on just one root stalk starting at about three feet off the ground today we're here in the Hollywood Hills and I have successfully hopefully successfully grafted a type A and type B avocado to an avocado root stock of a different variety with the hope that we're gonna have the two types thriving and growing together pollinating one another for maximum production all types of avocados the type a avocado that we've grafted is one of the most popular grown in the country being the Hass avocado and the type B is the second most popular at least before the Hass avocado was popularized in the United States and across the country is the fourth day avocado that's a Type B avocado which is on this side of the plant what we're gonna do first is I'm going to remove the graph and the graph practice that we used and utilized and here we are now the first week of August about two to three months ago we did a grafting method known as the approach graft and what we're gonna do now is simply remove the root stalk of the Hass approach graft to the root stalk of the avocado root stalk that we've used so that's what we're going to do together right now if you want to come around this side I'm going to go behind the tree so here we are with the Hass avocado this is the Hass avocado approach graft as you can see this is the grafted area this is the grafted Hass which is in its own container over here and what we're gonna do today is simply remove the Hass avocado like so and you can now pull the container away from the plant as you can see on the container avocado variety says Hass right there and you may notice that there's quite a bit of green happening around it this is all sucker growth from the root stock we're gonna be cleaning that up later the next thing we're gonna do is now sever here's the Hass on the backside we're gonna do the fourth date together next so come around to the other side we'll remove now the 4/k avocado so again this here is all sucker growth that you see even this branch over here is some of the sucker growth we can pull that out like so let me get you even closer remove another branch but we're gonna clean all this up towards the end but you can see and I want to share this with you since we're now closer you can see here's the fourth day avocado here is the container of the forte and if you come in closer what I want to share with you is the cambium tissues which is the underlying the bark of both the rootstock as well as the fourth day avocado have now joined and become one and now what we're going to do just like the Hass avocado is we're going to sever the - you may notice also about about a month ago so about a month ago what I did was I've begun to sever my way I went about half way into the fourth day avocado to basically encourage the graft to become stronger and more dependent on the graph then on its own route and so that's some of that callus tissue that you see here today we're gonna go all the way through there we go and now we're just gonna separate the two from one another and here we go if we take a look at the container here you can see it says avocado for a day so we just severed the Hass avocado and the fuerte avocado from the original container that they were in what we're gonna do next is a test that I've invented which I'm hoping to share with you called the graft stress test and the way that works is we're simply gonna take some wood it could be from another haast another forte but we have here some sucker growth from the root stock where we're simply going to take a cutting off of that looks quite vigorous and healthy if you take a look at it the leaves are in good condition the young growth is all in an upright condition keep in mind we've already pruned and severed the Hoss and the fourth day avocado from the original container so if there's any wilting that process should already begin now that I severed this wilting on this should begin and is expected as it's no longer connected to the original plant or any plant at all or even by putting it in water might extend the wilting process but we're not going to be connected to anything we're gonna see how well that graft took by doing again what I call the graft stress test what I'm gonna do is simply take this cutting over here and I'm attaching it to a stake which I prepared I've got some touring on it as you can see here and all I'm doing is basically attaching the twine and the steak to the avocado cutting and I'm keeping it alongside the avocado which is right behind it and we're gonna watch it wilt over the next 10 15 20 minutes or even up to an hour and then compare the two trees and here we go so this here is expected to wilt my Hostin 480 avocados finger crossed will not wilt that'll be the proof of success with our graph that we initiated about 2 to 3 months ago so I'm gonna do in the meantime is remove some of the suckers that are in between I'm gonna keep a few suckers just in the event of failure of one or both of my graft um but I'm hoping that didn't happen in the meantime I'm gonna remove some of this excessive sucker growth and hopefully check back with you in the next 15 20 30 minutes so we can compare the results and continue to clean up and then I'm gonna share with you some other steps before we conclude today is again so we just removed most of the suckers from the roof stock we've kept a couple again just in case this part over here is the Hass avocado this one over here is the fuerte that you see in peaking arm towards the top we've got these two backups rootstock suckers that we're keeping again just for insurance purposes in the meantime this here is the graft stress test that we've got if you take a look at these leaves now you can see that they're beginning to wilt they're starting to feel a lot softer and more limp again being that it's not connected to the plant nor is it resting in any water to help maintain the pressure within the plant whereas the ground if I touch these leaves are not exhibiting any sign of any stress and so I'm feeling more and more confident by the minute that we've accomplished graft success with the Austin fourth-down this particular root stock what we're going to do now is we're going to whitewash the entire structure the avocado of all fruit trees is the most sensitive to sunburn in the winter there is a phenomena known as Sun scald where if there's too much light on the bark it can result in burn just as it can burn in the summer when there's too much light on the tree's trunk as well being that the tree no longer has a canopy and also important at the time of planting again when the plant has no canopy there's too much light exposure to the tree trunk and that can result in tree burn so what we're gonna do instead of applying a chemical paint or a tar based product to the plant which again those products are designed to last for decades and centuries and potentially contaminate the soil as the tree's bark is going to replace itself out every one to three years we don't want any of those chemical products within the soil and lasting in the soil for decades instead what we're going to do is use this product over here which is the ivory again x3 in one plant guard protection against damaging sunburn insects and rodents and it for you Sonia Rosa's fruit and nut trees ornamental trees and shrubs and the product is registered material for use in organic agriculture and here we're using it for protecting newly installed plants and trees but also shields pruned and damaged surfaces this is an important point as well if you come in a little closer over here you'll notice over here is the top of the root stock as you can see this is a very large area and this is an area that will not be protected by itself for many many years even up to a decade until this particular Hass avocado branch and back here the fourth the avocado branch gets large enough that it ultimately protects and naturally shields this exposed surface from penetrating beetles termites and other pathogens from entering the heartwood this here is the center of the wood the heart of the plant I like describing as being the tree trunk and the lower branches which we need to protect and preserve to maximize the longevity the life and the health of the plant for hopefully many more decades to enjoy hopefully these wonderful and delicious avocado varieties for the many more years to come so what we're going to do now is we're going to simply take the ivory organics products when it arrives it comes in dry form so we've got the organic base powder and then over here we've got the bubble wrap oils if we can open it here and here's the oil vial and the oils include they're right here organic castor oil cinnamon oil clove oil garlic oil peppermint oil rosemary oil and spearmint oil so these oils will naturally create a defense when mixed together with the base powder to protect any disease and pathogens and pests from entering the exposed wood surfaces and then we're going to continue coating the entire tree trunk again from excessive amounts of light that will other result otherwise result in tree burn let me share this video with you from Griffith Park where we saw a pruned limb that was otherwise exposed by a lot of pests that entered the wood as it's going to take many more years for this to heal again the cyber organics products and again the concepts known as whitewashing will protect that exposed surface for the years that it's going to take for the plant to naturally heal unprotected let's check out what's going to happen and today we're here at the Griffith Park and I was just going for a walk and but it just had to share this tree that's a nom here at the park and if you take a look this large opening was once a branch that was pruned up from the tree at least 10 years ago possibly even 20 I just want to show you the damage within the tree and it's in the process of being hollowed out by termites and beetles take a look at all of these holes in here and if you zoom in a little closer you can even see the ants but they're trailing in and out of these tunnels and I've seen a lot of these ants carrying eggs and food and all these different particles within the plant the reason I'm bringing you out here is I'm trying to share the importance of coating your plant with the ivory organics three in one tree guard paint product and I'm gonna share that with you real quick check this out so here we're protecting the entire graph Union where we prune the approach graph and then we're gonna do the crown as well and you can see the crack that's happening between the wood as well as the bark and we're gonna fill that in so that can be another entryway for pennis we're gonna protect the entire surface we just did the same right here and then we're just gonna keep working our way down like so so we've just whitewashed the entire graph two zones we've whitewashed the pruned areas off the root stock which would be near the crown I said it's also known if we did a crown graph we would have grafted near that pruned area and now we're gonna continue whitewashing our way all the way down to the ground level as again the plant doesn't have a canopy to protect the underlying tree trunk so we're gonna continue whitewashing all the way down to the ground level I'll be doing the rest of that on my own time the other thing I want to share with you in regards to the graph stress test being that it's been about an hour but again the sun's gone down it's getting later in the and cooler in the day so the wilting process is a little bit slower but let me share with you the difference real quick if you can see again one more time this here is the cutting off of the root stock you can see that the entire plant is beginning to wilt whereas the grafted Scion selected wood is still quite vigorous so back here is the fourth day over here the hast these here are a couple extra suckers that were going to keep for a couple more days but eventually going to move these last two suckers and just allow the root stock to concentrate all the energy into these two selected proven excellent varieties of avocado in the meantime had one of these grafted varieties begin to wilt as this has I want to share with you a tip to hopefully reinvigorate that graft and help prevent it from building what I would do if this was the grafted wood is I would then cut the graft in half so what I'm doing here is I'm simply cutting it down to the next nearest bud and what I'm also going to do is cut each of the leaves and like so and what that's going to do is it's going to reduce the amount of water loss within the plant structure and give it a chance if there's any successful graft unions between the Scion wood and the grafted root stock by having less surface area that would hopefully turn the tide towards the graft and help keep the graft alive rather than begin to dry out and ultimately fail so this here's another helpful tip to make your graph succeed when you see failure shortly after removing the underlying pot from the approach graft method so hope this helps and further improves your success within your garden as well if you found this educational moment brought to you by Harbor
