Why my dwarf imperial mandarin in a pot does not produce flowers or fruit. My potted lemon and cumquats OK

My dwarf mandarin is in a deep pot (more than 1 metre) is about a metre high with lots of leaves. Otherwise seems healthy. I water and fertilize at same time as my lemon tree and cumquat trees in pots

Answer: Hi Julie,

Thank you for contacting us regarding your citrus tree.It is not normal that your mandarin hasn’t fruited and I hope I can help you to identify the problems.

Firstly, is the tree a grafted citrus? Grafting is the best way to ensure producing the best true to type fruits in a short period of time. Have you seen any flowers on the tree? Fruit sets after flower, lack of flowers could lead directly no fruit. There are number of reasons: lack of nutrients, water stress, incorrect cultivation, bad rootstock. If it does bloom but fail to form fruits, you should check your watering (too much?), lack of pollinator, low phosphorus in soil.
In general, try to use special citrus fertiliser in spring summer and autumn ( Dynamic Lifter Organic Fruit Food is a good option), which including extra phosphorus to encourage flowering and fruiting. Regular deep watering is essential particularly during warmer months. You can also add some liquid fertiliser during flower and fruit time, try Yates Thrive Citrus & Fruit Natural Fish & Seaweed+ Concentrate, the dual acting formula feed through both leaves and roots to boost healthy growth and prolific fruits.

Protect your tree from pest and disease and check regularly for first sign of infestation to ensure a healthy citrus.
If all the above points have been ticked, you may just need a big patient and a little more TLC, I am sure your citrus would reward you with bucket loads of fruits.

Hope this helps and happy gardening.

Best Regards,
Yates Horticulturalist
