Mexican Cypress Cupressus lusitanica
ABOUT
The plant known commonly as the Mexican cypress is a striking evergreen conifer that typically has a dense, conical shape. The leaves of this tree are small, scale-like, and arranged in somewhat flattened sprays that cling tightly to the branches, presenting a rich green to bluish or greyish-green color that remains vibrant throughout the year. The bark of the Mexican cypress is fibrous with a stringy texture, peeling off in narrow strips. It has a reddish-brown to greyish color, which often gives the tree an attractively rugged look. As the tree matures, the bark becomes deeply furrowed, adding to its character. The plant produces both male and female cones on the same tree. The male cones are small, elongated, and release pollen, while the female cones are more substantial, round, and woody. These female cones start out green but gradually mature to a dark brown color and can be seen conspicuously nestled among the foliage. Upon maturity, the cones open to release seeds, but some may remain closed and attached to the branches for many years. Overall, the Mexican cypress is admired for its symmetrical growth habit and lush, evergreen foliage that brings a sense of permanence and tranquility to landscapes. Its striking appearance, with a dense cloak of foliage and a rugged bark texture, makes it an impressive sight to behold.

WaterFor the Mexican Cypress, it is best to water deeply and infrequently to encourage deep root growth. Watering should occur once every 7 to 10 days, with adjustments made for rainfall, temperature, and soil conditions. During hot, dry periods, increase watering to every 5 to 7 days. Each watering session should provide enough water to moisten the soil to a depth of at least 12 inches, generally equating to 1 to 1.5 gallons for young trees and up to 5 gallons for mature trees, depending on size and soil type. Ensure the soil around the tree has good drainage to prevent waterlogging.
LightThe Mexican Cypress flourishes best in full sun conditions, so it should be placed in a location where it can receive at least six hours of direct sunlight daily. Partial shade is acceptable, but growth will be slower and less dense. Avoid deeply shaded spots as these do not provide sufficient light for healthy growth and development of the Mexican Cypress.
TemperatureThe Mexican Cypress can endure a wide range of temperatures but grows optimally in zones with temperatures between 68°F and 80°F. It can tolerate cold down to about 20°F; however, temperatures below this may damage or kill the tree. The plant can also withstand high temperatures, but prolonged exposure above 100°F might stress the plant. To prevent cold damage in colder climates, it's recommended to plant in a sheltered location.
PruningPruning the Mexican Cypress is necessary to maintain its shape and structural integrity, as well as to remove dead or diseased branches. The best time for pruning is in the late winter or early spring before new growth begins. It should be pruned at least once a year to shape it and to keep the size in check. If shaping hedges or topiaries, more frequent pruning may be necessary to maintain the desired form.
CleaningAs needed
SoilThe best soil mix for the Cedar of Goa (the most common name for Cupressus lusitanica) should be well-draining and fertile. A mixture of peat, sand, and loamy soil is often recommended to provide the right balance of moisture retention and drainage. The ideal soil pH should be between 5.5 and 7.0. Regular top-dressing with organic matter can help maintain soil fertility.
RepottingCedar of Goa trees do not need frequent repotting as they are relatively slow-growing and can develop deep root systems. Young trees might require repotting every 2 to 3 years to encourage growth. However, mature trees are usually repotted less often, typically every 3 to 5 years, in larger containers or planted outdoors if space permits.
Humidity & MistingCedar of Goa thrives best in moderate to high humidity conditions. While it can tolerate lower humidity levels, it is optimal to maintain a relative humidity level around 50-60%. Consistent humidity is beneficial but avoid overly wet environments to prevent potential fungal issues.
Suitable locationsIndoor

Life cycleCupressus lusitanica, commonly known as Mexican white cedar or Cedar of Goa, begins its life cycle as a seed, typically requiring a period of dormancy before germination. Once conditions are favorable, the seed germinates and develops into a seedling, characterized by its juvenile foliage. As the plant grows, it enters the sapling stage, where it starts to develop the adult scale-like leaves and begins vertical growth. The Mexican white cedar reaches maturity in several years, developing a woody stem and a conical shape, and it starts producing cones. The female cones upon pollination by male cones' pollen develop seeds, which when mature, are dispersed to start a new cycle. The plant continues to grow and can live for several centuries, all the while going through repeated cycles of seed production and dispersal.
PropogationPropogation time
Spring-Early Summer
Propogation: Mexican Cypress, scientifically known as Cupressus lusitanica, is most commonly propagated through seeds. The ideal time for sowing seeds is during spring, when the temperature ranges between 64 to 72 degrees Fahrenheit (18 to 22 degrees Celsius), providing a conducive environment for germination. To propagate Mexican Cypress from seeds, firstly, the seeds must be collected from ripe cones, which typically dry out and open in the fall. The seeds are then sown in a well-draining seed starting mix, lightly covered with soil, and kept moist until germination, which usually takes one to two months. Seedlings are gradually acclimatized to outdoor conditions before being transplanted to their final growing location. This method, while straightforward, may result in some variation among the offspring as they are not genetically identical to the parent plant.
