Holly tree help

Hi, we have bought a Holly tree (the common one) intention is to pot grow it. We was told it would be fine in its growing pot for some time (its a baby and 30cm high) however it cannot stand and topples.
Its in a 9cm pot.
It is a christmas present :/
Is it ok for now?
Generally speaking when should it be transfered to a bigger pot n wot size should that pot be (liters etc)?
Wots the best soil?
And how much should i be watering this baby Holly while it grows/establishes?

Thank you in advanced!

 

You could move it up to a 8in pot , kind of double the size as long as the existing pot is full of roots, which it should be.
As its an outdoor tree, you shouldn't need to water it until we get dry weather, probably in the spring some time.

As to compost, I'd use a JI no3 mixed with 25% sharp sand or fine grit.

Oh yeah, should add, there is no rush to repot until spring.

 

Hi,

If its 30cm high in a 9cm pot is not going to stay upright in any wind.

As @pete says go for a much larger pot 20cm to 30cm in size and try and use one with a base nearly as wide as its top , not one of the fancy pots with a very narrow base.

Though the plant may currently be in a peat based compost, do not use any in a bigger pot as its just too light and it could still blow over.

You can alway use some decent garden soil if you cannnot easily get JI no3.
You can even put some gravel ( not limestone) or stones in the bottom to help stop it from blowing over.

Watering, just keep it well moist, during any real dry period , assuming its outside, and keep it in a sheltered position during the winter, using some fleece or bubble wrap if its really frosty /thick snow.

 

A 30cm (12") plant in a 3.5" pot is IMO time for potting up, as by now the roots are probably coming out of the drainage holes. The advice already given is good, however I would prefer to increase the pot size gradually. This will encourge strong roots. Just my opinion.
