Yes it is,no problem.The "potted plants " section of this thread is interesting too.

Very interesting.....I may have to experiment with a couple of my seedlings.
Thanks for sharing!

interesting that they call it 100% perlite but then state that 10% is made up of non-perlite matter.

the day i read this post i tried roptting one of my citrus seedling in 100% perlite. now it is almost a month and there is no sign of new growth and the leaves are turning yelowish.

Did you notice this phrase:

nutrition is being added in the water

You need to add small amounts of fertilizer to the
pot, frequently.

thanks tomm didn't notice that.

since i am in zone 11, the nursery man which i buy the fertilizer from advised me not to fertilze in summer saying it will burn the plant. ??

In the case of a citrus tree, I think you need to find another nurseryman for proper nutritional advice. The university of Florida's IFAS advises fertilizing citrus up to six times from March through September. The correct advise is just the opposite. Summer is exactly the time to feed a citrus tree. Not fertilizing is what has gotten your tree in the condition it is in. - Millet

I have repotted two trees = one in a 75% perlite/potand tub mix,the other 50/50 of the two. They have both stayed evenly moist through winter and are both doing new growth now.They are also very light,so i have just put the pot inside a bigger pot to give it more stability. The weather has been terrible in new zealand for the past two months.Rain everyday and wicked storms with high winds.I put my trees under the house under flouresecent (spelt wrong) tubes(12 hours a day) and provide some humidity.They are all growing well and spring is around the corner. 80 % of my trees are in terracotta but i have a few in plastic.The two above are in plastic(under millets advice).
I plan to try chc/coir on a tree soon and give that a go but i bought a massive bag of perlite really cheap and have been using it for everything with some potting mix eg strawberries in pots,dwarf cherries x 2,tomatoes and in the garden soil.really stops the soil from compacting.Glad people found the link i provided interesting.I have fed my trees at half dose slow release fert with blood and bone.In a few months i will liquid feed at half strength every two weeks.Some of my trees have been dormant,so didnt feed those.some still continued to grow,so fed them through winter at low dose.Cheers everyone.

Well,most of my trees survived through a very wet and windy winter here in New Zealand.They are all putting out new growth now.The ones mentioned here are looking the best and stayed consistently moist with the minimum of effort.They never seem to get saturated.
I believe this was due to a few factors.
1.I made sure the pot size was 2 to 3 inches bigger than the rootball all around.
2.The combination of a pot and tub container mix with a large amount of perlite in a plastic pot.
3.Only feeding trees that were actively growing.
4.Low doses of slow release fert on the top at the beginning of spring.
5.interestingly,the high dose perlite trees mentioned havent had aphids or ants going on them.Which has been a problem for me in the past.
Just got to watch the aphids on the scene now.My dwarf cherries are in full bloom and fruiting and all my strawberries are on the go.Tomatoes/cucumbers/beans/sweet corn to follow.All my herbs have survived through winter(pots) and bursting into life.Very rewarding.
Regards to all here.
