What?! I love wasps! They eat pests like aphids. I also have jumping spiders that hang out on certain plants. I always thank them for protecting my plants so diligently.

The wasps have been on yours this week more than before as well? It only started for me a few weeks ago. I wonder if it could be some chemical Myrtaceae emit during certain times of the year.

I think one one of the hybrid araca seeds I planted in December 2018 is coming up. I had already given up and used the soil for other plants.





Some of my others from that batch:

Psidium myrtoides:




Eugenia aff. involucrata orange. The new growth on this one is gorgeous.


Eugenia aff. myrcianthes... was growing straight up until this spring




Eugenia involucrata 'Big black', not as pretty as when it has dark red new growth on it:


Plinia rivularis:


Jaboticaba de Posadas (has this one been renamed Lujan?):


Seedling in Guabiroba pot, but I think it's a weed:

I'm jealous. I'm having to water my potted plants 2-3 times a day. It's 97 and climbing, with 25% humidity. Did that mulberry bounce back?

I got similar on one of mine when I overfertilized. If the electrolyte concentration is too high it can't take up enough water .

Altough its such a good soil amendment to lower the ph i dont see manny people using this and it also shows on the market as i couldnt find sulphur branded as a product to lower the ph here.
I think manny people will learn from this forum .

Here is one: https://www.amazon.com/Espoma-UL30-Acidifier-Fertilizer-Multicolor/dp/B00YOVQXTS

A year later and putting on some nice growth. I'm hoping it's beyond the leaf browning issue.

I circled what look like remnants of ribs to me.

There are some intergeneric hybrids in Rosaceae. Apple x quince, pear x quince, shipova. Eriobotrya 'Coppertone' is believed to be an intergeneric hybrid of Eriobotrya deflexa x Rhaphiolepis indica or R. x delacourii (see study below). Here's a study attempting some interspecific and intergeneric loquat crosses.

What kind of graft, and how many days did they take to push?

Seems the local name is ucle.

I looked in The New Cactus Lexicon. Cereus forbesii is not in there, but from this site Cereus hankeanus is a synonym. http://www.llifle.com/Encyclopedia/CACTI/Family/Cactaceae/7058/Cereus_forbesii

The pictures of C. hankeanus are not an exact match, but it says there are three types of Cereus widespread in the Andes at 2000-2600 m. One with yellow-green fruits with magenta pulp, known as C. hankeanus; one with red fruit and purple-magena pulp, known as C. validus auctt; and one with red fruit and white pulp, known as C. huilunchu. It gives the range as Argentina. "Identification of the plants in our illustrations is very tentative, especially in the absence of information about their fruits."

Kew has a picture of C. hankeanus that looks similar, but with small spines. http://www.kew.org/science/tropamerica/imagedatabase/large264/cat_single264-1.htm

Edit: I missed an entry for C. forbesii. "As the original application of this name, which was described from sterile material, is very uncertain, it should be rejected as confused and untypifiable. It is however accepted by Kiesling as the correct name for a widespread Argentinian taxon, also known as C. validus auctt non Haw., of which the fruit has red pulp, here referred to C. hankeanus."

I'm tempted. Any pics of the mother tree? No fruit off it yet? Do you need the wasp?

They do get enough sun in the tent.

How do you know?
