Default Redwood vs clay planter?

I need to repot a young pomegranate tree; planter cracked. Not ready to put it in the ground yet; maybe not at all; depends on redesign of area.

Very large planters are pricey, so wondered if large redwood planter would do the trick. Any experience out there?

TIA

I'd always choose a wooden planter over pottery... wooden planters ere
fairly simple to construct from a section of privacy fence,
redwood/cedar both work well... how intricate depends on your
creativity.

I had three dwarf citrus in redwood tubs. These were cylendrical
instead of tapered, about 20 inches across and equally deep. After a
while, either the redwood would rot or else the steel straps would rust
through.

I repotted the dwarf lemon about three times. The navel orange and
kumquat about once; they were newer than the lemon. Then I had trouble
locating new redwood tubs. My drawf citrus are now in clay pots. These
are tapered, about 22 inches across at the top and equally deep.

As I recall, you are in southern California. Avoid plastic pots. They
will get hot in the sun and cook the pomegranate's roots. Clay pots and
redwood tubs (if you can find them) will stay cool as long as the
potting mix inside remains moist.

1. How long did it take for the redwood tubs to rot or straps rust?

2. Thanks for reminder about no plastic pots.

3. BTW, I saw some redwood tubs on Craigs list for a decent price.

That is an often-repeated "fact" but I wonder if it is a bit too
simplistic. If you have standard terracotta-coloured pots I would think
it is true. But what if you have white plastic pots and dark-coloured
clay pots? I would bet on the white plastic remaining cooler than the
dark clay. Then, of course, you have the cooling effect of water
evaporating through the clay. That's not true of glazed clay pots,
however, where evaporation can't occur. On the other hand, you are more
likely to find a plant drying out in an unglazed clay pot than a plastic
one. Then there is the consideration of what you want in winter. A dark
plastic pot which heats up quickly may be preferable to a light-coloured
clay one which keeps the roots cold!

I would think that it might depend on the type of plant you are growing.
Cacti and other succulents won't mind their roots heating up or being
dry for extended periods. Most normal plants won't like hot or dry roots.

If the OP intends moving the plants around then large clay containers
will be very heavy. I would go for white plastic, or terracotta plastic
painted white.

It was almost 10 years. The dwarf lemon was a little over 30 years old
when it died. I was then told that dwarf citrus in containers rarely
live longer than 25 years. In 30 years, I started with a redwood tub,
got a new tub at about 10 years, and a third one at about 20 years.
Then I switched to clay pots at about the time the lemon died. My
replacement lemon now gives more fruit than anyone can use.

My original dwarf kumquat committed suicide long after I moved it to a
clay pot. Its roots clogged the drain hole at the bottom of the pot,
and it drowned. Now I occasionally check the drain holes of all three
pots. This was not a problem with the redtubs I previously used because
each had four drain holes.

2. Thanks for reminder about no plastic pots.

Alternative is plastic.

I had planted tomatoes in a trough I made from a deteriorating redwood
picnic table. It lasted maybe three years before rotting out.
