You can schedule the fruiting of your calamansi trees so that the fruits will be harvested when prices are high. Usually, calamansi fetches a high price during the months of November and December because the supply is limited and it is also towards the Christmas season when things to buy are more expensive.
When we visited the farm of Patricio Perez in Balaong, San Miguel, Bulacan in the early 1990s, he had 800 three-year-old calamansi between young mango trees. From them, he was harvesting 700 kilos of fruits per week. At that time his calamansi was his big money maker that took care of his family’s daily needs as well as the salaries of his five helpers on the farm.
Perez explained that there are ups and downs not only in the price of calamansi in the market but also the productivity of the trees. In the month of February, when the supply of fruits is plentiful, calamansi sells ex-farm at P8 per kilo. But in November and December, the price could be a high P25 per kilo. And that’s why he had studied to time the harvesting of his calamansi in the months when the price is high.
How did he do that? Well, he achieved that by proper timing of fertilization and pruning. Pat explained that the calamansi fruit is usually ready for harvest about four months from flowering. So he made his trees flower four months before December He trimmed his trees in late May and then fertilizing them heavily in June. After this heavy fertilization, the trees will produce a new set of leaves and flowers soon after.
But to keep the trees productive continuously, there should be a regular program of fertilization. That is why Pat applied organic fertilizer (manure from his piggery) once a month. Every month, he also sprayed foliar fertilizet, and every week, he applied a combination of urea and complete fertilizers after irrigating the trees.
Now you know how you can time the fruiting of your calamansi trees so can get a higher price for your harvest. (Zac B. Sarian, Memoirs of an Agri Journalist)
