I have a grafted Mary Lane growing in about 70% shade. Leaves are fat as hell. I think the saplings want shade and sandy soil.

I've lived on Big Island seen these fools learn from all the same people. Just because it rains a lot and your tree grows big doesn't give you the right to give advice. Learn some real skills.

This right here is a perfect example of what I'm talking about. Anyone growing a 30ft annona doesn't know much about pruning.

Agreed, the fruits are not easy to pick from a tall tree but that said many doesnt get tall at al unless you count six meters as tall?

I've seen rollinias here that get 50 feet tall (16 meters) in good soil. Mine on lava rock is over 30 feet tall. I get plenty, and more than plenty fruits, from lower branches, so don't bother with pruning...let the birds eat the ones at the top. Ofcourse for commercial production everything needs to be kept at easily pickable height.

After reviewing the answers here and making a similar post not too long ago, it sounds like a good idea to top your rollinias at a young age and grow wide instead of tall.

For some reason, most people in Hawaii and other tropics lack canopy management skills. So take their advice with a grain of salt. It must be an ego thing where the faster they grow a taller tree, the better the farmer they think they are.


Ready to resurrect this post.

What is the verdict on pruning Rolinia?

Received scions today. Excellent,

Wondering if anyone has knowledge of the best tasting late Season Grape Varieties. Also, does a harvest time chart exist? I couldn't find one.

Just made a post about this. Found M parafilm horrible for softer wood cleft grafts but great for hard wood bark grafts.

You want to talk to me like a kook, but the reality is that ground temperatures determine growth. So if I can get a black pot heating up in the sun then I will get earlier growth. Seen it many times trying to plant potted plants too early. They will grow faster in pots just from the roots being warmer.

And just a side note. I've seen the only successful way of grafting off-season annona's already budded out to be with bagging method.

My original graft failure was in the shade with a different type of parafilm product. I wanted to warm everything up for a couple days after a rain. Since that pic, Ive moved the pots to a partial sun area and removed the bags. I have scions pushing buds already. I grafted too early in the season and the idea was to trick rootstock to push buds with greenhouse effect. I understand your concerns and how young annona like partial shade.

So I regrafted everything with different tape. Bagged them, and put the potts in the sun 🌞 to wake these mfers up. Will keep you updated.



I think the bags is the reason of your graft failure.  It cook the scion.  What I would do is using the cherimoya leaf and partially wrap around the scion and tie the leaf to the scion to provide the shade and heat.  The idea is to prevent direct sun light, but still have the heat and brightness.  Leave the plant in the sun to keep the rootstock active.

Okay. Thought rootstock needed heat to wake up. Will adjust. Had them in partial shade before. It just rotted. I've had 85% success rate in a hot ass greenhouse during May with overhead watering every day.

I'm not a fan of lollipop 🍭 annona trees

Cut it three to four nodes above the graft union. Regrow it...

Thanks brother. This is a good nugget of info

For what its worth, my graft take percentage sky rocketed when I started wrapping the unions with flagging tape as Brad recommended. I wrap the scion with parafilm. Before that I tried wrapping the whole thing with parafilm or electrical tape, or grafting strips. I got the best results by far with flagging tape.

This is the best I've used too. I regrafted everything with this brand tape. Will keep you updated.

Here's the parafilm brand I use.

Thanks for the tips. Yeah I'm pretty much doing all these. Must be bad timing. I did partially double wrap the union with green flag tape, more for identification and labeling. Last year I did over 500 with 85% success rate but that was April-May.

With annona only one side of cambium needs to line up and I use a shaving razor blade to make small incision on the root stock. My inserts are super tight and I hold the bottom of the union to keep it from splitting further than the scion.

Appreciate your take. Most likely bad timing.

Doug, I have a little more experience than you, been grafting for over 30 years. I do teach grafting to some friends and CRFG members.

My comments/suggestion for you besides the failures just being bad timing, nothing you can improve for that with the grafting method. Here's my suggestion, you may already be doing some of these things when grafting. I only use parafilm and it seems to work fine, didn't try buddy tape.

1. Make sure you cut the scion wood and rootstock surface as flat as you can. I see many beginners cut the scion wood, very uneven surface and they think it is good. This just takes praction.
2. Same on the cut surface of the rootstock, I suggest to look at the surface and make it as flat and smooth as you can.
3. Make sure you have the freshes scion wood you can use to increase graft take
4. Wrap the scionwood first with the parafilm, only one stretched layer as you wind it around all open surface. Reason to have only one stretched layer is so the tape will breathe and the new buds will pop through the tape so no need to remove it.
5. Wrap the graft union with parafilm after you insert the scion wood about 1" below and 1/2" above the rootstock/scion mating area.
6. When wraping the graft union section, you can put on more than 1 layer of parafilm since no buds are going to grow there. Again, make sure when you wrap it, stretch the tape 2x the length of the normal unwound tape.
7. Now to apply force which is needed to the mating surface of the scion wood and rootstock, you can use any of the mention tapes. I like to use the cheap green garden tape from Home Depot. Stretch the tape for pressure around the graft union. If you are not making this wrap tight, it may be the reason for the moisture in your grafts. There is no other place the water can get into the graft union.

8. After the new scion grows out buds, 4-12 weeks depending on the fruit tree you are grafting, you can think about cutting and removing only the green tape at the graft union.

That is all there is. Mostly just practice, practice, like anything else we do. Hope this helps you a little.

I do about 1,000 grafts a year. Just got plenty of time to work on my hobby. The graft success rate depends on the fruit tree variety I'm grafting. For mulberry, avocado, loquats, figs, it is above 75%, for citrus, jujube, persimmon, cherimoya, it is about 60%. For the difficult to graft fruit trees like lychee and guava, my success rate is 10-25%.

Anyways, I salvaged what I could and regrafted with the old tape brand. Will keep you posted.

Maybe I was a couple weeks early. The thing that makes me think otherwise is how much damage is done to the rootstock from the missed graft. Usually the rootstock needs a little snip below the graft union
 But these misses are doing more damage.

Good point on storing the tape. I met an old timer who kept his in the freezer. I also seal it in a ziplock baggy.

if you get 0/40, maybe the timing is off.
I've talked to nursery growers and propagators down south, and even they have seen results like that when trying off season.
 
I would say my favorite tape is buddy tape.
But parafilm works just as good.
To get a tight union on stuff like jaboticabas, I will use the green plant tie tape over the union.
Keep in mind though that mangos and annonas don't like it as tight, although it needs to be tight...it's a balance. With those plants, I just twist the parafilm sideways and wrap it like a cord to get the strength needed.

Make sure to store them in a cool dark dry place or else the tapes will degrade. I realize I will buy new tapes each year even though I haven't used them all.

If that was the case I would at least have some successful. When I go 0/40 something else is up.

Also, thanks for the tip on flagging tape. Will give that a try.

I quit using parafilm because it cracks before the grafts are healed.  I get near perfect take rates using just the flagging tape on the unions.  It doesnt crack and it comes off super easy.

As far as permeability specs etc of different tapes, those probably go out the window when you wrap your union in multiple layers. 

I don't think the issue you are seeing is water getting into the graft.  If you pulled the tape tight over it it isnt leaking.  I think maybe you just are not getting a tight bond on the unions.  You need to use something stronger to hold the unions together tight.

Last year I had around 85% success rate with heavy overhead watering by others in a greenhouse. Scions got soaked everyday. Never had that issue with the other tape.

I see moisture trapped in my BuddyTape wrapped grafts / scions all the time, but it doesn't seem to be a deal breaker for me. If you're trying to graft right now and rain is getting into your grafts, of course you're going to have issues. Sometimes you don't really have a choice like with stonefruits and other temperate fruit trees that need grafts before bud break, but you can't just chuck a graft on a plant cause you have the time and the scion and have success in every case.

Great example, citrus, it grows well when it's hot out. I graft them May to July no problems cause they start growing right away. If I threw on a citrus graft right now, it would get all soggy and would be unlikely to take.

The only issue with Parafilm in comparison to BuddyTape is that it's thick, but it is stretchy! So get it a bit thinner by pulling on it, and also, wrap from the top down of your scion, not bottom up, cause it will more effectively shed the rain if we get that. This winter has been wet so naturally grafts are going to be a bit more challenging compared to a bone dry year.

I'm wondering if there is a better wrapping technique to avoid whatever I'm experiencing with this tape. Usually I pre wrap the scion and wrap the union at the end. This could be channeling all the moisture into the graft union because the union tape sits on top the scion tape.

 If I don't pre wrap the scion and wrap the union and scion with one large piece of tape starting at the graft union, excess moisture will be harder to reach the union. This what I think is happening.

Bold statement.  Here is another one.  All I use is parafilm and my cleft grafts turn out just fine in cherimoya, mango, white sapote, and many others.  I don’t think moisture retention is the problem.  I wrap my grafts at the contact point with parafilm, then wrap again tightly with flagging tape to improve cambium contact.  Voilà
