How to Care for a Croton Petra

It is common for people to have a bad first impression of this plant because when acquiring new croton, some or all of its foliage will be lost after a few days. It causes people to mistake it for a fussy plant, but this is a normal behavior of the croton when moving from location to place with a different climate.

The croton Petra does not desire to be moved, so when this happens, it can go into shock quickly, causing the loss of its leaves. One recommendation is to avoid moving the plant as much as possible. However, if you are forced to move the plant out of place, you should not be scared by the loss of leaves but rather concentrate on caring for it until the leaves grow back. After this period, the plant will be resistant again. Some of the care that the croton plant requires to include:


The Croton Petra needs sunlight to have healthy and beautiful leaves and does not tolerate the cold. The more sun, the more attractive it becomes. So it is ideal for your backyard or that space where there is strong sunlight and is not the best choice for indoor environments. But, if you want to take a chance, choose the brightest place possible, where at least gets a little sun (near a window, for example) and avoid air conditioning.

In places without adequate lighting, the leaves start to look ugly and can die. If you notice signs of withered and lifeless leaves, move it immediately to a sunny location. And don’t forget to clean the leaves regularly as, inside, the croton can accumulate dust, which makes the leaves ugly and dull.


You need to plant the Croton Petra in a pot with a drainage hole. This is non-negotiable. The croton is a plant prone to root rot, so overwatering can be “deadly” for it. And what happens if you go overboard with watering and there is no drainage in the pot? The water would remain stagnant at the bottom and contribute to causing fungus or root rot problems. Having clarified this, let’s now talk 

Irrigation Guidelines of the Croton Petra

In summer, it needs abundant watering, and you will have to make sure that the substrate never dries up completely. It is easy to water it up to three or four times a week in the hottest months of the year.

In winter, as the temperatures are colder, the water needs vary, and you can reduce watering without letting (as in summer) the soil dry out completely since if this happens, the plant will suffer. For guidance, in winter, you will need to water your croton at least once a week. Remember that it may be difficult to establish days to water. Thus, the real key to knowing when to water is learning to read your plants, look at the soil, and interpret whether it needs water or not.
