Tropical Fruit Discussion / Papaya Seedlings
« on: May 30, 2020, 09:35:13 PM »
All my backyard papaya plants are from 2012 so I thought it was time to start some new plantings.  I germinated in a Park Seed tray store bought (Aloha Seed) and also seeds from papayas growing in my backyard.  It took approx. 30 days, but all the seeds did sprout and grew to about 4-5" and I transferred them to larger pots.  Sadly, many have started to wilt and die after I moved them outside to a plastic pop up greenhouse.
I'm at a loss to figure out what's going wrong.
Help.

Tropical Fruit Discussion / Papaya Topping
« on: January 05, 2019, 09:33:11 PM »
Some of the 6-year-old papaya plants in my backyard are getting pretty tall and the fruit is more than 10' above the ground.  I noticed that some plants that were knocked in half by wind storms a couple of years ago have recovered and started fruiting.  I was wondering if it would be a good idea to cut the tall plants down to about 4' and hope for the best?

Tropical Fruit Discussion / Ultrasonic Pest Repellers
« on: January 05, 2019, 07:35:40 PM »
Out of desperation, I bought an ultrasonic pest repeller at Amazon (only $35) and I'm now trying to see if it will help with my two biggest problems, ground squirrels and rats.  I know these things have had spotty reviews in the past, but this one seemed to have some favorable ones that gave me hope that it might work.
Has anyone else had luck with these things?
I'm not talking about the little ones that plug into an inside outlet and chase away mice and spiders.  This one supposedly will deter larger critters like raccoons, squirrels, deer, etc.

Tropical Fruit Discussion / Rats Started Eating My Papayas
« on: March 18, 2018, 06:45:54 PM »
I finally moved my Ring battery-powered camera and caught the pesky critters that suddenly found a taste for my papayas.

Now I just need to find a way to deal with them.
They don't seem to like the Rat X bait and have shied away from the Rat Zappers so I'm trying the old tried and true Victor snap traps.

Tropical Fruit Discussion / What Is Eating My Papayas?
« on: November 15, 2017, 06:24:36 PM »
This is the second papaya I've found with a round hole in it just after it had started to ripen on the plant.  Suspects include the pesky squirrel, rats or the ever-present mockingbird.

Tropical Fruit Discussion / Hass Avocado - how long before harvest?
« on: June 16, 2017, 04:11:28 PM »
Finally I got a Hass avocado tree to find a sweet spot in my backyard and set fruit, but it's difficult finding information on just how long it will be before the fruit is ready for harvest.  The fruit is walnut to golf ball size right now and I'm guessing it won't be ready until the end of the year.
Any information about the length of time between flowering and harvest for this variety would be appreciated.

Tropical Fruit Discussion / High Winds and a Gopher
« on: January 21, 2017, 02:50:48 PM »
Yesterday's storm that blew through San Diego had some strong wind gusts that knocked down several papaya plants along with the shade cover over my spa.
Today I looked out and saw the fallen papaya stems moving and discovered that it wasn't so much the wind that did them in, but a pesky gopher who was busy finishing the job.
Over two inches of much needed rain fell in my area yesterday, but now I've got the underground invader to deal with.

Tropical Fruit Discussion / Hass Avocado as a Shade Tree?
« on: August 20, 2016, 04:35:52 PM »
Last year I finally cut down a Carrotwood tree in my backyard that was a constant source of leaf and other litter.  Then the only other trees shading my yard, which were in my neighbor's yards were toppled by the wind storms in February.  Now it gets pretty hot in the yard even with my shade canopies.
The one bit of good news is that I've finally got a Hass avocado tree that is flourishing in the spot where the Carrotwood tree used to be and it's now grown to over 7 feet tall.
My dilemma is whether or not to start trimming it to a manageable size for fruit harvesting or let it go to 15+ feet for use as a shade tree?

Tropical Fruit Discussion / Up Potting
« on: June 08, 2016, 05:27:34 PM »
I just ordered a Glenn Mango from "Fast Growing Trees" and their information brochure recommends quite a bit of gradual up potting every two or three years.  They recommend going from 3 gal. to 7 gal. to 15 gal. to 20 gal. containers.
I was simply planning to put the 3 gal. plant into a half whiskey barrel container with good drainage when it arrives and forego all the transplanting.
Does it really help that much to disturb the plant every couple of years with a re-potting?

Tropical Fruit Discussion / My ongoing battle with squirrels
« on: May 06, 2016, 07:26:33 PM »
The number of squirrels attacking my backyard plants (fruit) had dropped dramatically, but there were still a few left and they were causing problems.
Last week a remarkable thing happened when one of the rabbits that regularly munches on my backyard grass to exception to a visiting squirrel and chased him out of the yard.  This is now a regular occurrence and we couldn't be happier.  Today, two rabbits teamed up to chase the squirrel.  Long overdue.  I'm trying to get a video of the action.

Tropical Fruit Discussion / San Diego Area Wind Storms
« on: February 07, 2016, 03:51:12 PM »
The two big wind storms at the end of November and the end of December last year pretty much destroyed the majority of the fruit on my papaya plants, broke three shade covers beyond repair and knocked two of my neighbor's half dead Bottle Brush trees into my backyard.  The cold snap in January didn't help the papayas much either.
The good news is that I could never get my neighbor to cut down the Bottle Brush trees that were overhanging into my yard and now he has to deal with them.  Also on the other side of my yard an ugly clump of 20'+ Carrotwood sapling in my other neighbor's yard were blown straight down the slope behind his house and the view improved.  At least all my stuff blew down and was damaged within the confines of my backyard. :)
Looks like this will be a rebuilding year if that pesky El Nino gives me some breaks.
Anyone else suffer excessive wind damage out here in Calif.?

Tropical Fruit Discussion / Wind Storm Snapped The Tops Off my Papayas
« on: November 18, 2015, 02:58:02 PM »
Early Monday morning (3:00 AM) an unusual (for San Diego) wind storm picked up and tossed two 8' X 20' shade structures off my patio and down my back slope.  In the process the tops of several of my papaya plants were ripped off and I lost a lot of large fruit that hadn't started to ripen yet.
Two other shade structures survived because they were tied down to anchors in the ground and not just attached to concrete blocks.
Amazingly the shade structures survived and are still usable, but the papaya plants are in bad shape.
Is it possible the the plants with the sheared off tops will survive?
Any comments will be appreciated.

Tropical Fruit Discussion / Can I ripen a green papaya?
« on: October 24, 2015, 05:09:08 PM »
The wind just blew a medium sized green papaya off my plant and I was wondering if there was any way to ripen it?  No hint of yellow and I'm guessing it's probably a goner.

Tropical Fruit Discussion / 50% Shade Cloth Solution
« on: July 14, 2015, 06:15:21 PM »
I think I found a solution to the problem of trying to grow potted avocados and papayas in my south facing and windy backyard.
I know most folks have been saying that the plants should have full sun, however, I purchased some 8' X 20' shade structures with 50% shade cloth and the plants are doing much better.
Early morning and late afternoon sun can still hit most plants directly, but the intense midday sun gets filtered through the shade cloth.
Since we're under water use restrictions here in San Diego I'm adding a third shade structure for some in ground plantings and shifting more of my backyard away from grass and into mulched planting areas.
Of course, they just announced that we're mostly likely in for a very strong El Nino this winter so everything could possibly just blow away.  ::)

Tropical Fruit Discussion / Papayas from store bought fruit seeds
« on: May 25, 2015, 03:51:42 PM »
I've had equal luck growing fruit bearing papaya plants from seeds bought from Aloha Seed or the University of Hawaii and seeds from papayas bought at the local grocery store.
This monster was just harvested today because it appeared to have enough yellow on it and also because it was in plain view on a plant in my front yard.
The seeds came from a Mexican papaya my wife bought at the store.  I planted seeds (5 per container) and then planned to use the plants for decoration around the yard.  What a surprise when one plant started flowering and bearing fruit.

Tropical Fruit Discussion / Wind Barriers
« on: April 12, 2015, 09:18:38 PM »
I was thinking of using shade cloth has a wind barrier in my back yard to protect some of my younger mangoes, papayas and avocados.  I was guessing that a 40% sun screen cloth with grommets would work to eliminate the dry winds that blow my plants around.  Anyone have any experience blocking the wind with shade cloth/fabric?

Tropical Fruit Discussion / How Often Can I Use Agri-Fos?
« on: March 04, 2015, 03:59:19 PM »
A couple of my avocado trees are just limping along with sparse foliage and several blackened branches.  These are small trees that I've only had for a couple of years.  I've started using Agri-Fos as a foliar spray to see if it helps control the disease and was wondering how often I can spray the trees?

They are closing the golf course behind my house so I need to act rather quickly to clear some old headaches from my backyard before they put up fencing that will make it harder to access.
I'm having a gnarly old eucalyptus on my back slope and a troublesome carrot wood tree removed from my backyard and now need a replacement shade tree to provide some protection for my tropical plants.
My San Diego (zone 10) backyard is south facing (full sun) and a bit windy.
I'm trying to find a relatively fast growing shade tree that won't be too messy and can tolerate the windy conditions.
The tree will be used to protect my papayas, young mango trees, and young avocado trees from getting blasted by the full afternoon sun.
Any ideas would be appreciated.

Tropical Fruit Discussion / Putting the Avocados Back in Containers
« on: December 01, 2014, 04:11:55 PM »
Well, I've killed two and injured three more avocado trees in my attempt to grow them in the ground in my backyard.
A leafless Holiday and a near leafless Fuerte started to recover after I dug them up and returned them to containers - I have no idea what is going wrong.  Now my Sir Prize is showing similar signs of stress when it had previously been going strong.  I'm headed out to buy a half whiskey barrel sized pot for my two year old Hass because it looks like it will be leafless in a few weeks - I'd rather see it live even if only in a container.
Peaches, mangoes, oranges and papayas seem to tolerate the backyard and its soil, but not the avocados.

Tropical Fruit Discussion / Water Restrictions in San Diego
« on: October 24, 2014, 03:50:29 PM »
Next month I may become an outlaw because if I see one of my plants in need of water I'm not going to worry about day and time restrictions on water use set up by some bureaucrats who are still approving massive residential and commercial real estate developments within this City.
I have my own conservation measures in place which allow for greater flexibility in dealing with the water needs of my plants while still greatly reducing my water usage.

http://www.sandiego.gov/water/conservation/drought/prohibitions.shtml
Water Only 3 Assigned Days A Week
Water no more than 3 days per week on the following assigned days, which are determined by your address or type of dwelling:
Residences with odd-numbered addresses (301 Drought Drive): Water ONLY on Sundays, Tuesdays & Thursdays.
Residences with even-numbered addresses (500 Conservation Circle): Water ONLY on Saturdays, Mondays  & Wednesdays.
Apartments, condominiums and businesses: Water ONLY on Mondays, Wednesdays & Fridays.

Water at the Right Times
November 1 to May 31, water between 4 pm-10 am for ONLY 7 MINUTES when using a standard sprinkler system.
June 1 to October 31, water between 6 pm-10 am for ONLY 10 MINUTES when using a standard sprinkler system.

Tropical Fruit Discussion / Papayas at Last
« on: October 15, 2014, 05:00:59 PM »
Several of my two year old Papaya plants are finally setting fruit after most dropped off last year.
Even one I grew from seeds harvested from a Mexican papaya my wife ate has set fruit.
Still hit or miss as to which plants (either in the ground or potted) will produce.
Fortunately, I like them as a decorative plant even if they don't produce.
These small fruit sets might not seem like much to most of you, but after the long wait they seem OK to me.

Tropical Fruit Discussion / The Squirrels Are Gone
« on: August 24, 2014, 01:03:06 PM »
For the first time since moving into our house in 1997 I haven't seen a ground squirrel in almost a month.
I can only hope this continues.
I don't know whether I should be thanking that big hawk that was hanging around all summer or the little dogs on either side of our yard.
I got about 20 squirrels with the Rat Zapper this spring and actually bought another one to protect the papayas and peaches.  Then they were gone.
I'm still in shock.
We have never been without ground squirrels attacking our plants, digging in all our patio pots, stealing our oranges, ravaging our tomatoes and tunneling into our back slope.
I feel blessed, but I'm totally perplexed.

Tropical Fruit Discussion / When to Pick My LIttle Cado Avocados
« on: August 09, 2014, 04:49:56 PM »
After watching all the flowers and small fruit fall off my other young avocado trees I was left with three avocados on my Little Cado.

They are a little over 4 inches long and look ready, but since I've never grown avocados before I just don't know.
Should I go for it and see if one will ripen off the tree?

I finally disassembled (cut up) and threw away the small (6'x6'x6') plastic greenhouse I purchased 2 years ago.
It was OK for the first year, but I realized that I had become a slave to the thing with constant opening and closing of flaps to control the temperature/humidity and it was too expensive to heat in the winter while being next to impossible to cool in the summer.
I finally realized that my small plants would do just as well in protected areas of my backyard and that I could start seedlings enclosed in inexpensive plastic containers from Home Depot.
I realize that I also displaced a lot of fruit flies, ants, spiders and beetles, but it had to be done.

Tropical Fruit Discussion / Converting Lawn to Planting Areas
« on: July 23, 2014, 03:53:11 PM »
I'm thinking about planting several more fruit (avocado, mango, papaya) trees in my backyard and converting lawn areas into continuous stretches of mulched planting area.  I got tired of mowing and trimming around some of my fruit trees and figured it would be easier to replace the grass with mulch.
The weeds shouldn't be too hard to manage, but I wonder if there are any other problems I might encounter if I convert several hundred square feet from grass to mulched planting beds?
I saw the fallacy of putting down a weed barrier when my neighbor had that done before converting his front yard from grass to decorative rock - the weeds simple grew on top of the barrier in between the rocks.
Any ideas on what type of mulch would be best?
With the water restrictions here in San Diego I figure it might be better to lose some of the grass area.
