Requirements for Growing Carob Tree

Requirements for Growing Carob Tree


Carob tree needs full sun and a location that is sheltered from the wind. If growing in a hot climate, it’ll not mind growing in a position that receives partial sun. For the best pods, ensure it gets a minimum of 3-4 hours of direct sunlight every day.


The carob tree grows in difficult positions and poor soil including sloppy hillsides with deep sandy soil or loam, even arid. It does not tolerate acidic or wet soils and requires adequate drainage.


It is resistant to drought and grows well in a lack of water. However, watering must be provided during dry seasons, especially if the tree is grown for its fruit.

Carob Tree Care

Carob tree care is easy! The tree is ideally grown in regions with Mediterranean and Middle Eastern frost-free warm climates. It’s cold tolerant as well–a fully developed carob tree can withstand temperatures down to 20 F (-7 C), but frost during the flowering period can reduce or sometimes prevent fruiting.


Fertilizer is often unnecessary for carob trees. Side-dressing the plant with well-rotted manure, twice a year is sufficient. Additionally, a dose of 8-3-9 ratio fertilizer can be applied occasionally to give the plant a boost.

It’s a wild tree, which means you can leave it without pruning. However, pruning a carob tree when it is young helps it attain the desired shape you want.

The tree must be pruned regularly so that air and light can penetrate. Young stems can be removed without affecting the production of carob. Also remove the tangled, weak, and damaged or diseased branches from time to time.

Pests and Diseases

There are only a few pests and diseases that disturb this tough tree. Be aware of squirrels, scale insects, and carob moths. In diseases, it gets killed due to root rot because of overwatering.

    • Ive had one i grew from a seed and its still in a pot. Its about 15 years old and because its had a hard life as I have, it’s stunted but last year it had an amazing growth spurt because i started looking after it I guess. I had to cut a big branch off it it grew so one sided. I want to repot it. I’m a bit worried, I have become very fond of it. I dont know the best time to repot it or even how to prune it properly. Any thing anyone can add that might help with the growing of my carob tree in a pot would be appreciated. It looks gnarly and spotty sometimes but just keeps on growing. Dont give up on yours. They are amazingly resilient. I planted 5 seeds from Kings and they all came up. I didnt even scar or soak them. I gave the others away and wish I hadnt as the other 4 are dead. I hate trusting people with plants and tree seedlings, they arent trustworthy enough. Anyway sorry I wasnt much help but dont worry about the spots etc, just have faith. Cheers. Jane in New Zealand.
