USDA Will Revise Zone Map
« on: February 14, 2017, 09:37:17 AM »
Yesterday I was listening to a gardening program on WLRN's "Topical Currents," and the gardening experts who were answering callers' questions said the USDA is going to once again revise their climate zone map.  Zone 11 will start at Hollywood Blvd. in Broward County.  We can probably say good-bye to winter weather in South Florida!  (I like 50's and 60's.  Boo-hoo!)

I am not surprised. Most of Pine Island on the west coast is likely a 10B or 11. There are all kinds of ultra tropicals grown successfully from Pine Island south. I would imagine the zone 11 extends even further than Hollywood Blvd on the east coast.

Interesting. I have noted a change in the past 10 years. Probably bad news for lychees in this area.

TBRFC had a field trip to ECHO at Ft. Myers and Fruitscapes on Pine Island late last year. This is a picture of Fruitscapes' 3-4 year old unprotected breadfruit tree.
If I recall correctly, it has already produced some fruit there. I would not be surprised if Pine Island is USDA zone 11.

You mean mother nature reacts to the USDA zone map?

That tree fruits. But it was also brought in as a large tree last summer, or the summer before. That being said, there are at least one or two other fruiting breadfruit in the area.

we have several zone 11 areas in soucal. I doubt breadfruit would grow there but you never know.

My friend in Homestead has harvested about 200 breadfruit from one tree in a subdivision.

My breadfruit tree matured 10-20 last year - I forgot the final #.  If this winter stays as warm like the current pattern, my guess is about 40 fruit.  Time will tell but he tree definitely has enough size to hold 50 or more..

What does your tree look like in the winter here?

Someone in Naples said they have had one lychee bloom in a decade or something crazy like that due to no cold. But he's in an area where he grows ultra tropicals with zero protection.

It has been discussed in other threads in the past that its not necessarily the cold that triggers lychee blooms.  Keep in mind that lychees are grown and fruit in other areas that also grow and fruit ultra tropicals such as Hawaii and Thailand (just to name a couple).   Growing the right variety for the location is critical  if you want more consistent production.   For instance, planting an Emperor is great for its fruit size and flavor however it does not do well in our location from year to year and most growers attribute to improper climate.

Rob, you might be thinking of the thread where we were discussing mango reaction to cold. I thought that lychee had a pretty strict chill requirement.

I think lychees can be encouraged towards bloom if given proper nutrition, but I think there is still a need for chill.

My mauritius has had 2 crops in 10 years. My sweetheart had a small crop last year and is going for a near full bloom this year, and it's only about 5 or 6 years old. I do control the nutrition on the sweetheart, where the mauritius gets the home owner association's fertilization routine.

Don of Going Bananas said that lychee production in the redlands area declined significantly from past decades do the warmup.

Well this may suck. I planted a Lychee last year.  :'(
It seems like more and more people are getting rid of theirs.

I wouldn't give up that easily. Sweet Heart has surprised me. It started bearing last year, and this year has nearly a full bloom. The quality / flavor of sweet heart is absolutely ridiculous.

I think the lychee tends to produce better in a highly organic soil with plenty of potassium, a strong micronutrient package, and zero added nitrogen. Harry, who grows his lychees on muck in Davie, has had very high success -- nearly annual fruiting, despite the fact that he's in a small heat island (there is some sort of air pattern over that area that keeps temps a couple of degrees warmer).

But it is a long haul. You shouldn't expect regular cropping for 6 - 8 or more years.

Well this may suck. I planted a Lychee last year.  :'(

Lychees are being planted here less also and in my town they rarely fruit. Even those with the most modest chill requirements like kwai mai pink and Mauritius have declining frequency of cropping on the equator side of 20 latitude.

Almost all of the mature lychees around Naples last year seemed to be loaded.

Lichi have had great production here in the last three years. This year might be better given that we've had over 190 chill hours and a very wet winter.
