Tropical Fruit Discussion / Selecting mature fruit from the tree
« on: February 16, 2017, 12:05:08 PM »
Some fruits more than others are at their best when left to mature on the tree. I'm also guessing that some fruit keeps better on the tree than if they are harvested and stored, unless you have special storage facilities.
My question is how to harvest and/or treat fruit for the best eating quality. One issue for me is how to select fruit on the tree that is mature/ready for picking. I'm sure that it depends on the fruit and non-commercial growers have much more leeway for getting that perfect fruit, so I'd like to hear how people do this.
I was never able to pick good apricots from the tree and noted that the best tasting were the ones that had fallen, so I rigged up a cloth to catch the fruit when it fell. I couldn't see/feel any difference between the fruit still on the tree and the fruit I caught in the cloth, but the fallen apricots were way juicier and sweeter. I do the same with my mangos now - in part because because of the numbers and the trees are so high that it would be a major undertaking to check the individual fruits.
Citrus, I used to check with a gentle tug but the mandarins often sounded like I was tearing something inside. I now rotate the fruit 90 degrees to the stem and pull even more gently. That seems to work well with Valencia and Mandarin oranges and grapefruit but doesn't work with Key limes which are at their best when still green, before they yellow and they are far from their best if they are left to fall from the tree.
I also seem to find that the citrus at the top and on the South side of the trees seem to mature first, presumably because of sun exposure.

Tropical Fruit Discussion / Greetings from a new member

Greetings. First of all, a big thank-you to all the people who organize and contribute to this forum. I'm looking forward to the help and inspiration that seem to abound here.

Iím here as an amateur gardener trying to care for (and maybe improve) the garden I inherited when I bought a house in Loreto, a small city on the Sea of Cortez coast of the Baja Peninsula in Mexico. Most of my previous gardening was in Northern England. I'm a retired university academic who studied and taught physiology on the Westside of Los Angeles for 20 years.

The climate here in Loreto is described as hot desert. There doesnít seem to be a direct equivalent in the US climate charts although 10b and 11 may be close. The relatively closed Sea of Cortez remains warm throughout the year and therefore keeps winters warmer. Average temperatures range between 15C and 35C (10C min, 37C max). Average annual rainfall is 6.3 inches although it is very variable. An 11-year drought ended recently and hurricane can drop 18Ē of rain in a single day. Humidity ranges between 30% and 80% for almost any day of the year.

Fruit trees I inherited are Mango (Manzana/Kent, Ataulfo/Manila, and an Ivory/Nan Doh Mai look-alike), Valencia orange, mandarin, key lime, grapefruit (yellow). Not sure a tamarind counts as fruit. The house was empty for several years so the trees had been neglected. I now recycle 3-4 cubic yards of compost/farmyard manure into the garden every year. One of the orange trees produced wild lemons with a single orange on one thin branch. I pruned the Ďlemoní branches and now have an orange tree. The mandarin trees seem capricious with delicious, juicy fruit in 2 seasons, separated by 2 seasons of dry, inedible fruit and I canít figure what Iíve done differently. A large branch of the lime tree came down in a storm last year, revealing a significant fungus infiltration, suggesting the tree should be replaced. I suspect the fungus was due to poor pruning practices in the past.

Iíve also added lychee, pomegranate, lemon and a pink grapefruit from local nurseries. They had no identification on them. The pomegranates taste quite acid and the pink grapefruit has yet to bear fruit after 3 years. The lychee had 1 delicious fruit when I bought it but has barely grown in the last 3 years and always develops brown tips on the leaves. This year a new wall that protects it from wind and daily soil soaking seems to have encouraged new leaf growth without brown tips. Papayas from the seeds of store-bought fruit are just starting to flower and melons also seem like tropical fruit to me.

Itís a challenge to find a source of plants with any provenance here. Long-distance relocating will also be a challenge due to agricultural concerns so I may be somewhat burdened with Ďchancyí buys although Iím trying to improve my luck by getting to know local growers.
