Hey Oscar, I know what you are talking about, especially the watermelons although with research and genetically modified seeds, they are producing sweeter and tastier fruit without the seeds.

An example of a fruit that tastes the same without seeds is the Tango Tangerine.  It is basically a seedless version of W. Murcott.  It was produced by irridatiating W. Murcott causing a mutation that likely renders the pollen inactive. 

I really like the Sweetheart Lychee for the extremely large, golfball sized fruit and the shrivelled seed.  Some other examples of fruit that tastes good if not better with atrophied seeds are Durian and mango.  From my personal experiences, I have purchased several Durians with atrophied seeds and they tasted much sweeter and creamier than their large seeded counterparts.  Also, for Manilla type mangoes(and probably others), I always try to select the Thinner fruit as they often have atrophied, very very thin seeds compared to the larger wider fruits with the fully formed seeds.  My theory is that the energy that would have gone into producing the seed went into the formation of more sugars.  This is just what I have noticed and I could be totally wrong

Lycheeluva, I will make it up to lord Mauritius if this years crop tastes better.  I will even consider purchasing a Mauritius since its supposed to be one of the more dependable fruiting lychees. 

Oscar, next time I go back, I will look for the Black Lychee

I've been doing a lot of research on what variety the Sweetheart might actually be and my best guess is either Fei Tsze Siu or Sah Keng.  Both of these have been grown in Australia and have very large fruit of good quality.  If you google pictures for Fei Tsze Siu, you will find several pics that look a lot like Sweetheart.  As for Sah Keng, I'm going mainly based on the descriptions of this cultivar-especially the large size, growth habit and good flesh to seed ratio.

My favorite Lychees in order of preference are
No Mai Tsze- tasted these in China and Hong Kong, sweet, crisp flesh, very white colored flesh, average size fruit, no medicinal taste at all- my parents favorite as well
Sweetheart- very large fruit, very small seed, smells and tastes of honey
Emperor-I love fully ripened Emperors, the ones with very little tartness, the ones picked even a little early are much less sweet and pretty tart.  I ordered some last year from Lycheesonline.com.  The fully ripened, fully colored, full sized Emperor with abortive seed-I will rate on par with a good Sweetheart.
Hak Ip-standard lychee
Brewster-I love the flesh, one of my favorites, if not for the seed that takes up 99.99% of the fruit
Mauritius-going to order some from Lycheesonline this year to verify it is one of my least favorite lychees, sorry Lycheeluva

Still looking for a source for Garnet Lychee airlayer so please let me know if anyone has one available for sale.

I have would like to reserve a No Mai Tsze and Hanging Green if you have them available.  I'm in Southern California.  I have a Hanging Green from the experimental station at Hilo Hawaii but it is not doing well.  Thanks in advance!

Hey everyone, I finally attempted to inarch my Maha Chanok mango with my Manilla mango in an attempt to create a Maha Chanok mango with multiple rootstocks.  I decided to top my Maha Chanok to get the hormones going so I have a scion about 12 inches long.  I already cut off all the leaves and the scion is about 1/2 inch thick.  The scion is not fully swollen, only partially, so it may not be the best scion to use for grafting but its free to a good home.  I live in San Diego California.

You should read the label carefully.  They may have added minors, trace elements or other things geared towards roses but it shouldn't hurt your Cherimoya.

I always try to apply fertilizer, even organic fertilizer, away from the trunk of my tree.  I would apply the fertilizer near the drip line or slightly within the drip line.  I would suggest giving it less nitrogen and more P-K.  I like to give my plants some E.B. Stone Organic fertilizer, I think its something like "Bloom" and the numbers are 0-10-10.  You may also want to give it dilute feeding of Fish emulsion and kelp emulsion for the minors and trace.

Cherimoyas can grow very large in a season if given too much Nitrogen.  The P-K should also help to sweeten up the fruit.

There are two  varieties of mf. I'm guessing that is from the larger fruiting hairy variety

Depends what type of Orchids you have but many of the orchids like morning sunlight, try to avoid direct sunlight.  They also hate tap water, try using RO water.  Many people kill Phalenopsis Orchids my overwatering.  When you water, water deeply or simply submerse your orchid container in some RO water for several minutes so It can saturate the orchid mix and roots.  Let it completely drain.  You should let your orchid dry out before watering again.  You likely won't need to water for another 2-4 weeks depending on the type of orchid, its size, and the size of the pot it is in.  Many types of orchids like some mistings with RO water.  Cold weather and fewer hours of light may induce flowering depending on the type of orchid.  Good luck!

Mango
Lychee
Cherimoya
Dragonfruit-preferably with Brix close to 18.0, red or purple fleshed unless its the yellow DF
Mara Des Boise/Chilean Guava

After reading Ohiojay's post and checking out Bernie Dizon's website, I decided I'm going to attempt to put multiple rootstocks onto my Maha Chanok Mango.  I've already purchased a sacrificial Manilla Mango and will attempt my first mango graft soon.  I've never grafted Mango before so I'm guessing it will take many attempts but at least I don't have to top my Manilla Mango untill the graft takes. 

Ohiojay, do you have any advice?  Thanks in advance!

Hey Oscar, the Tazziberries(Chilean Guava) are extremely, I mean absolutely delicious!  No kidding, they smell and taste kind of like cotton candy mixed with berry.  Unfortunately, mine were very small, smaller than a blueberry and my specific variety didn't turn completely red, mine were very light pink with some green on it.  If they were bigger and more red, they would be even more amazing.
