I would leave it alone. What temps did they experience? Where are located?

I'm located in New York and the low was low 50s. It's obviously a potted specimen

50's shouldn't have hurt it. We get that low and lower here (so. Fla.) and mine never experienced stress. Did you do anything to excess like water or fertilizer?

Nope, the only other thing is there was some wind

Unknown then, because 50's definitely shouldn't hurt it, even with windy conditions.

Hmm it must have gotten colder then because it's the only explanation.

Maybe you can check the historical temperature and humidity records for your zip code?

Other than temperature perhaps low humidity and the wind had a dissicating effect?

I've never known anyone to grow it!! Do you get fruit?

No Meris, I'll never get fruit from it up here. Its just an ornamental or was...haha

gnappi, all I know is it got shocked by the weather. I clipped the really bad leaves off. The stems have turned black too unfortunately.

There are a few down here that have survived mid 30's, mine has been in the 40's without damage. I put it in the ground this spring as it was being stunted in the pot and has flushed out nicely after planting it.

I hope to get fruit in the 2017 season, from what I see they bear fairly young.

Yea I heard they bear young too. A delicious fruit! Better than a cherimoya imo.

I just thought of something, this tree was in a greenhouse at a local nursery before I bought it so perhaps just a change of environment?

Congrats Tony, hope you get incredible fruits.

Do they shed leaves in their native countries or only here in the US?

Tony, you have four soursop? WOW! you must like them a LOT! How large / old are they? Were they in pots or the ground for the cold snaps we had this past winter?

Mine is ~7' tall and I guess about 5 years old and was potted until recently.

BTW, I now always defoliate all of my annona to get them to flush earlier

Two were planted in the ground two years ago and two were planted in the ground last year. They were grown from seed. The ones planted in the ground first are almost twice as thick.

The other farmers said this was the most profitable fruit because no one was growing it commercially and there is no competition here. We grew them to see how much fruit the tree can produce. We got eight trees.

Our farm is next to the Everglades. The humidity is really high. The morning mist is 15 feet tall and covers the tree with tiny water droplets everyday. The morning mist is very thick where you could barely see through it. In the City there is no mist.

They defoliate and flower when the new leaves grow back. It is not due to the cold down here in Miami. They are just flowering now in April.

The dormant period is not the cold here. The dormant period is when the tree defoliate by itself.

That's strange because mine only defoliate if they dry out too much. But otherwise they never lose all their leaves.

Is it possible there are different types soursop depending on location and some defoliate and others don't?

Here is a picture of the flower forming under the leaves.

Max, since they are all grown from seed I am sure some variations in cool hardiness, flower and defoliation times, some likely mandated by local climate.

I defoliate all of my annona now and they seem to flush veg growth sooner, which so far seems to make them flower sooner. Many recommend letting nature do it and it seems many take more control and do it early.

Tony, looks like you have great space there! Are you planning a commercial grow?

Gnappi generally I let nature do its thing but container garden isn't natural anyway

In the background of the first picture I got a little over 300 post set up for dragon fruit. The rest of the open space will be growing longan and lychee commercially.

I planted different varieties of fruit trees so I could have different fruits to eat. This little guava tree produces over 100 fruits per year. It flowers about 4 different times. It struggles a little when it has over 30 fruits at one time. It takes longer for the fruits to get big.

My Thai guava fruits will still grow huge even when the cold and insects kill off all the leaves. The flowers on this tree survive so I will get more guava soon. It takes about 7 month for the fruit to get huge without any leaves. The big guava in the picture is only half it's size. It will grow double it's size in about another 2 months. The little one will get just as big but it will take another 3 months. Only 5 fruits survived when the temperature dropped in the 40s.

Tony that is awesome. I'd love a piece of land like that in South Florida.

I take it ultra tropicals like mangosteen, marang, and Durian wouldn't survive there eh?

I just planted a small Durian I grew from seed. It grew at the house so it should survive out at the farm. It will probably lose all of it's leaves in a cold winter, but when the new leaves grow back, it will fruit like my other trees.

The farm is just north of the Redland where the humidity in the morning is as high as 93%. I got a dense mist every morning so it is probably a 100%.

Tony, how do you deal with scale and fruit fly on your guava?

These two are vexing me to the point I am ready to pull all my guava except the lemon guava which are immune to scale.

I bag all my fruit and am regularly spraying with hort oil as well as removing scale by hand and with waterjet.

I try not to use pesticides on the fruit plant. I just rub the scales dead when they get big enough. Don't let the old mature ones with the brown covering live to long. They give birth to a bunch of small white scales which you can't kill until they get bigger. They are the tiny white spots on the plant.

I don't have a problem with the fruit flies as much. There is not much fruit for them to eat. The farmers have seasonal trees that fruit once a year. They starved the rest of the year and die off. I look for tiny spots on the guava's skin. I know when there is a worm. When there is no spots, then I know the fruit it good. The spot are really small The size of a needle point. There is usually an small indentation at the spot.

The problem I have is with the Web worms. They kill the new leaves where the flower bloom forms. They build their little cocoon there.

The white flies mess up guava tree before and covered the tree in sooty mold from the honey dew it secreted on top of the leaves. I stripped all the leaves off the guava and the white flies left.

Thx Tony, I remove the scale and on some trees like my 2 caimito and at some point they seem to stop coming back after a while, but the guava for some reason ALWAYS have the scale. Funny the hort oil (mineral oil) works fine on everything else.

I notice my guava are pest magnets too. I think I've found three different pest but they are well controlled. I just use my hands or I bought something called "zero tolerance " that works well. It's an OMRI pesticide from herbal extracts but scale killed my lime tree this winter.

Tony, I hope the Durian works out, that'd be pretty freekin cool!

What do you use as fertilizer to get so many guavas?

The guava is a commercial variety, but I forgot the name. It suppose to produce a bunch of fruit. It is red inside and you can smell when it gets ripe. Right now it has over a 100 flowers getting ready to bloom. The fruits hardly ever fall off. Last year I only got about 30 flowers each time because of the white flies.

I use the cheap fertilizer 10-10-10. It is a balance fertilizer. Once the tree gets to 10 feet, I am going to switch to a fertilizer with very little posphurus.

I was going to propagate some branches from that guava tree, but found out it was a really cheap fruit and I couldn't get much for them. I get tired of eating the guava so I give them to my neighbor.

I was wondering if you use double sided type around the trunk, would it make it hard for the scales to climb up the tree.

What is the best type of Guava to eat in your opinion?

Double sided tape would leach at least some toxins into the plant I would think.

My Guava has grown like crazy to the size a tree. Produces very few fruit, but a hell of a lot of mealybugs.

Theres a product called tanglefoot that is for the purpose of preventing climbing insects on trees. I have not used it but am told it works and will not harm trees.
