How to grow Calamansi tree – growing condition and care information:

Well-drained soil, better loamy soil, moist soil in the fruits season and better to put mulch

How to care:
Design for easy to pick the fruits (when there are thorns it’s important but not all cultivars have thorns), add to the soil, organic matter, humus and fertilizer, in location with hot summer sun that the main trunk is expose to the sun better to better to whitewash (lime paint)

What is the best way to start growing:
Plant / Seed / Cutting / Air layering

Propagate by cutting:
Propagating require: sterilize knife, sterilize soil (put the soil in microwave), soil that will keep moist like: peat soil, coconut coir or peat moss, better to do it in in temperature of 25-28C (77-82F) possible higher, high humidity, moist soil (don’t let it dry), use root growth hormone and when growing from cutting it’s important, to give humidity that will be like fog

Is it necessary to graft or cutting?
Yes, necessary to ensure the existent of the fruits and quality of the fruits and there are different parameters: size, taste (sweet, sour or something in between), juicy or dry, amount of seeds or seedless, season of the fruits (different cultivars have different dates for the fruits), better to graft more than one cultivar or more than on citrus.

Cutting need to use for the base of the tree for: disease-free, base that fit for different soils, resistance for drought, base that won’t resist for grafting or specific cultivar for the fruits.

Difficulties/Problems with growing:
When tree is young, very sensitive to citrus leaf miner

Planting season:
Spring to summer in hardiness zone 8-10a, spring or autumn hardiness zone 10b-11a, possible also in summer and winter the main problem it’s hot and cold days that might cause future problem and even kill the plant, hardiness zone 11b+ planted all year

How to plant:
Dig a hole as deep as the current root ball plus extra 20-40%, put in the hole organic matter, hummus and dried leaves and mix it with some soil, put the tree and loos little bit the root ball above the hole, plant the tree and cover it and don’t push the soil too much strong but not too much lightly because it won’t be stable, after planting put mulch to keep moist on soil, put water, for the next two weeks put every day (better in the morning) , better to take that the tree will be stable, and if not support it with bamboo or a stick that it won’t fall.

Pests and diseases:
Citrus leaf miner, aphids, citrus foot rot, ant, citrus gummosis

Pruning season:
End of the winter, beginning of the spring

How to prune:
Dead branches, cross branches, density branch grown, trim infected branches

Size of the plant:
2-5 m, 80-200 inches (6-15 feet), possible to grow it as dwarf 30-70cm

Growth speed in optimal condition:
Medium growing / Slow growing

Water requirement:
Average amount of water, usually the plant need more water in the fruits season, but usually it’s when there are rains and if raining season delay need to increase the amount of water that the fruits won’t be dry and won’t explode.

Light conditions in optimal condition for growing:
Full Sun to full shade with a lot of light

Growing also possible in pots, planter, flowerpot, containers:
Yes, when grow in container need to choose the desirable container if it’s small plant it directly if it’s a big container bigger than 30%-50% than the root ball, every time that the tree arrive to full capacity need to switch to bigger until arrives to desirable size, better to switch the soil once in few years soil lose the viability over time and it’s efficient of care for the tree, when it’s not possible to switch all the soil just part of the soil in the side of the roots (don’t afraid from root cutting), it will bear fruits also in 5-10gallon (40 liter) container (but bigger is better), drainage it’s important and need to make holes and to use peat soil and maybe some lava grit in the bottom or something like that, put a bottom for the container and when water the plant let it fill the bottom but also need to dry in the same day, better to grow as dwarf tree or to grow it as bonsai.
