I, too, placed an order over a month ago, and my account shows the order is still "processing". But I've always had good service from RPS, and I don't think they are scamming us.  It's much more likely that this is a COVID-related delay. I'm not sure if mail service between here and Germany is at all reliable right now, so I'm going to give them some more time before I get concerned.

Sounds like possible over fertilization and too much sun exposure.  Thanks all, for your help!!!

Great seller, seeds arrived in good time, with extra seeds.  :-) Recommended.

Hi - I sent you a PM.  Thanks!

Looks like a nutrient problem. Rambutans are very sensitive to chemical fertilizers, especially when small plants. Is that osmocote granules? Suggest switching to organic ferts. Flush out with water to remove excess salts and nutrients.

Yes, it IS osmocote!  Thank you for your suggestion, Oscar!  I have been a little heavy handed with the fertilizer recently, so will give it a flush and try the organic.  And my other rambutan seedlings as well. :-)  Mahalo

GEMS, I saw these for sale at Fruitlovers.com, you might try there. - Jen

Have not tried other ones.  After trying this one, I saw no need to try others. 

It has 4,3 out of 5 stars on Android. Are you sure it's the same app?  It's sometimes spelled "Pl@ntNet", although in the app store it's spelled "PlantNet Plant Identification".

I think its the same one.  What the heck, I think I'll try it.  :-)  Thanks for your recommendation.  - Jen

PM sent!!!!!!!!!!

Very interesting! Amazon has this kit for the reasonable price of $64, but there are zero reviews.

The best tissue and simplest it's meristem which contains undifferentiated cells.
Virtually all parts of the plant can be used to cloning via callus induction. Even from a single viable cell, but this requires expensive equipment and special techniques. Each plant has a different need and requires chemicals to be used.

For instance it's possible to take a lime from store and grow callus from it, then shoots and finally root the shoots. Or use the shoots and micrograft them to a rootstock.

Very very interesting. So this can be done with lime skin? Or which part of a purchased lime? So would this be possible from a mango skin or piece of stem?


Who here has experience doing tissue culture? Thanks!

I did some tissue culture work as part of my Masters degree project (selected loblolly pine cultivars).  I'm surprised to see a kit offered for general use, as what struck me the most about tissue culture production is the absolute need for a sterile environment. It is easiest to keep things sterile in a laboratory, where you can work under dust removing hoods and keep an alcohol flame burning to sterilize your cutting tools.  Your agar medium starts out sterile but it's so easy to introduce unwanted organisms to it as you transfer your plant tissues.  I had issues with keeping sterile even in a lab - I can't imagine trying to do it at my house.  That said, I must say I am intrigued by the kit for sale and might even buy one!  :-)

i would spray or paint with steri-prune or something similar to seal the wound

It's pretty deep - I can try to seal it, or do you think the whole thing should be cut off?

Thanks for these suggestions! Do you know of herbaceous plants similar in size to bananas and papayas? Or perhaps non-fruit tree-like plants of that size?

Whats the largest one that you know of? Can it rival a banana or papaya "tree"?

Tree tomato (cyphomandra betacea) gets quite tall. I had one in a pot in Portland, OR that was about 6-7'.  It had a decent trunk diameter as well.  Not as tall as some papayas, but decent size.

Hi Maryoto,

Everything arrived in excellent condition! I have quite literally never received a package so quickly from your region! It was sent out on the 12th, but came in on the 20th of the same month!! WOW... Everything was in great shape and arrived at an UNBELIEVABLE speed! I still can't believe how fast this package got here.

Thanks!

Where in the US are you located? My package was seized by US customs and I received an empty envelope...Glad you received yours.

SoTasty, you need to go to the USDA APHIS web site and fill out the paperwork for a permit 587 (import small lots of seed from foreign countries).  When your permit is approved, APHIS will send you labels and a permit that you send to the seed vendor, they will use the label on your seed package, sending it directly to the incoming port city where there is a parcel inspection (Miami, Honolulu, Seattle, etc.).  Then the parcel comes to you after inspection.  It has taken me awhile to learn all this, finally got my permit, and hopefully getting my first seed order from overseas soon!  - Jen
