It is "Sour Guava". It is called "Cas" in Costa Rica. You can make the most delicious drink in the world with it. I always wanted to know if I could buy "Cas" in the U.S. so I researched it a few years back and found that its name in english is "Sour Guava" of course it was all imported and $25 a pound. Super rare stuff outside of central america, Cas is in ...

You want to cull after fruit set for the reason you mentioned, pollination, and also because some of the fruits in a cluster will not be quite as strong as others. You won't be able to tell which flowers will set, and which ones are the highest quality, until after pollination. Most Guava varieties are self pollinating, but you may get a bigger harvest ...

As far as I'm aware, this is detrimental to each tree and you should cut off 2 of them to focus the available light, moisture, and nutrients to the one tree. The trees may be sprouts from a larger single tree that was cut down for some reason or they may be sprouts from guava seeds that were dropped there naturally by birds or as part of a compost heap or ...

You've got something chowing chewing big time..on the leaves of your little tree. I would clear a circle of 2' diameter around the base of your tree. Remove all weeds, as many weed roots possible without damaging the roots of this tree. Look at your other plants nearby to see if there is any of the same damage. Make sure that the trunk of your baby tree ...

Okay, you say it was in a smaller pot and the roots hadn't filled that pot. I'm afraid putting it in a much larger pot was the worst thing you could have done if you wanted to keep the tree small. If the rootball that was present originally hadn't completely filled the pot, it would have been best to leave it in that pot until it actually needed repotting, ...

While I have never grown guava and I know very little about it, I can take a guess: Maybe it's the light, moisture and/or temperature. I eat sempervivum leaves on occasion. I notice that when it's been hot, dry and sunny for a while, they tend to taste like malic acid (the stuff in green apples that makes them sour). When it's been cooler and not as sunny ...

I'd repot it into the next size up of pot, and give it a good watering. Looks like the humidity could improve also. I don't see disease on the plant, but that's just from the pics. About pruning, you can head back some of that long, gangly growth, take out anything dead, broken, or rubbing, etc. I wouldn't prune too hard when it's in that shape though. The ...

I believe guava can be grown as a multi-stemmed tree, and this is probably what you have. I'm not familiar with growing guava outside, but other fruit trees are sometimes planted close together to a) provide pollinators without taking up a lot of space and b) to stunt the growth of the trees, so they stay a reasonable size. It is also possible that this is ...

It is disease. What is important to know here (Australia) is whether this is puccinia psidii (Myrtle Rust) because the nursery will have to be informed. official info at https://www.environment.gov.au/biodiversity/invasive-species/diseases-fungi-and-parasites/myrtle-rust Contact details for help in Victoria at: https://agriculture.vic.gov.au/biosecurity/...

Different people on the web recommend soaking the seed in water for 2 weeks before planting sandwiching the seed inside a damp folded paper towel, sealing it in a plastic bag, and hanging it up in direct sunlight till they germinate. putting the seed in boiling water for 5 minutes before planting to break the dormancy. Whatever option you try, germination ...

I have Psidium guajava seedlings growing not 3 years old. They were well watered and fertilised with good looking fruit. However they are very sour. I have one self sown seedling that is a wildling that was never watered, but gave the most sweet and tasty fruit. Sometimes a first crop can be poor so I will wait until next year's crop to see what is really ...

I have a strawberry guava and unless I fertilize it, I don’t get sweet, ripe fruit. Even then, I get plenty of green, sour ones. My mom picks those, boils them, and sweetens to make juice.
