On a separate note:
The citrus plants I've been experimenting with are proving to be really fascinating. I've planted three varieties: (i) Calamansi (limau kasturi), (ii) Satsuma orange (mikan), and (iii) Key Lime.
I then exposed them to numerous stresses, including drought, predation, competition with other crops etc., and interestingly, the satsuma orange is doing extremely well. For one, none of the caterpillars even tried eating the leaves, whereas the key limes were almost completely wiped out. Also, the satsumas are growing much faster than both the key limes and calamasi; even in the drought test, where I cut watering down to just 1L every few weeks, the satsumas seem to be growing faster anyhow.
Right now, my interest has turned to mangoes. Partly because I've come across possibly one of the best tasting mangoes I've ever tasted. But also because mangoes originate from Southeast Asia and the Indo-China region. So since it is from here, why aren't we planting more?
Interesting enough, I found out why.
There are actually two families of mangoes, which are not only separated by place of origin, but also by distinct physiological characteristics. One is the Indian mango, which are typically ovoid shaped with blushes of red/pink on its skin; the other, is the Southeast Asian mango, which are oblong shaped with either yellow or green skin. Also, Indian mangoes are monoembryonic, i.e. when the seed germinate, only one shoot comes up; whereas Southeast Asian mangoes are polyembryonic, i.e. they produce multiple shoots at first, but eventually only 1-2 shoots survive to form the tree.
Indian mangoes do not like humidity. In fact, nearly all bloodlines with Indian mango ancestry will blight during the rainy season. Southeast Asian mangoes however have been adapted to wet conditions, and hence are more tolerant of diseases. However, 80% of all mangoes produced world are Indian mangoes, produced in cooler tropical climates away from the equator. Also, Indian mangoes have the largest number of variants and hybrids; there are literally 1,000 registered cultivars and counting. Compared to Southeast Asian mangoes, there are probably just a couple dozen or so registered varieties at present.
So why is this important? Because it means that Southeast Asian mangoes have a tremendous amount of potential yet to be unlocked. With the kooky way climate shift is taking place, it will be necessary to find cultivars that can tolerate high heat, high humidity conditions. And seeing how the mango industry is worth about USD$300 billion globally, why is Malaysia missing out? We're not even in the Top 10 producers!
So why not? Hmm... as I've discovered, it is because we are still using very archaic methods of cultivation. We still grow 200 trees per hectare, some even only 100 trees per hectare or even less. But in South Africa, they are growing 1500 trees per hectare. That's right... 1500 trees per hectare. Same with India.
It is often cited that diseases are a key reason why we can't plant high density mangoes. But if the growing areas with higher rainfall than Malaysia can do it, what then is stopping us from following suit?
The Satsuma orange sounds interesting. Wonder how's the fruit taste like (sweet) compared to the Chinese Mandarin Orange (Lou Kam). Shall chec with my nursery supplier, maybe get a a few for trial as I had not been doing well on my trial of Limau Kipas & Perut. My problem with lime is that it died of drought when it's new, but once established, it should be well. Next problem is pest. Leaf miners & weevils & fruit flies. Had a tree infested with the black fungus. I read the Satsuma is drought tolerant but easily died on over watering.

Co-incidentally I had started on some mangoes recently. Had a Super Manila Sweet & Apple mangoes on my trial and it had fruited. Made some grafts and recently planted a few. Just got in some ChokAnan ( they are naming this Langkawi Mangoes :-) ), Thong Dam aka Black Gold, Nam Doc Mai aka Water Lily, Madu.
Would like to get my hands on Harumanis & R2E2
What do you think of these varieties on doing in Sabah? Interior, hill, rain fed.
