pruning alone.. never hurt or killed anything ...

pruning becomes easy.. when you can produce a goal.. and move towards it ...

what is your plan with this tree ... continue as a potted plant?? ... eventually be planted in the ground??? ... bonsai??? .. etc ...

if you can do so... we can help you along ...

welcome to the forums ... there is also a citrus and houseplants forums ... should we fail you here ....

ps: how big is that pot.. hard to tell without a scale ... wondering how long a tree will be happy in what looks like a smallish pot ... also.. is there drainage holes in the bottom ...

Hello Ken!

This tree will continue as a potted plant in the near future (for the next few years at least). The pot is about 6 litres in capacity, 26cm tall. I am planning to change the pot next month. And yeap, there are drainage holes at the bottom. This is a 3 year old lime tree, grown from seed.

hi

where are you ... will the tree go dormant in any sense??? ... that is usually the best time to repot ....

if not dormant.. i am sure there is a down season ...a resting period ... it would be best to do it when the tree is inactive... rather than in fast spring growth ....

the most important thing in a pot.. is the media ... rather than the plant ... choosing your future media is very important ... we could discuss that ...

what i would consider .... is pruning PROPERLY at that time... reducing to one trunk ... and setting the tree slightly askew ... so the single trunk is straight ...

on the other hand ... back to your pruning goal ... two trunks is a bit more artistic ... so you will have to figure that off ..

i do note IMPROPER pruning on the left trunk.. never leave stubs ... it should be removed .... properly ...

except for scale ... the theory is no different based on tree size ... a good pair of pruning shears would help ... they dont have to be real expensive ... but at lest a step up from the cheapest ....

I see, I am in Singapore, so the tree won't go dormant.

I am just worried about the tree structure in the future. I saw online that co-dominant trees have weak structure. But I am not sure if it will matter, since the tree is going to stay indoors for quite awhile.

Thank you for all your help!

Sometimes I leave extra stem until tree is much bigger, just so that there is more volume to enjoy in the meantime. I usually reduce height of second stem so that tree's leaves are not all at same height. In some cases I keep both stems for a long time. When what I want is tree height sooner than later, from the beginning I grow it as one stem.
