that's an umbrella
plant.
where are the brown spots? it looks like the leaves are variegated in color? or are those the spots you're talking about?
i've got a miniture umbrella and it's supposed to stay evenly moist. i'd think the full size version would have the same requirement.
am i reading your post correctly? the spots appeared AFTER you transplanted it to the terra cotta planter? if that is what you are saying, it sounds like it's drying out too quickly - i wouldn't transplant it again (too much shock). i'd just water it a bit better.
what you could do is get a container that's wider than the clay planter and fill it with a couple of inches of water and then set the clay pot in it and let it soak up all the water. that should give it a decent soak, then check the soil at the top of the planter - if it still seems dryish, then do some watering from the top.
water from the top weekly (or even every 4-5 days if the soil is dry) and do a good soak. pour in some water and let it settle for about 5 minutes and pour in some more and let it settle. maybe even another dose - if you look at the side of the pot you should see it darken in color a bit when the water reaches it from the inside. also, it will feel cool and moist if the soil that's in the pot is fully soaked.
do the bottom soak thing every other week.
unglazed clay pots really dry the soil out! i only use those types of pots for
cactus and other
succulents.
you're best to leave it for the moment, tho...for at least 6 months to a year. don't want you to lose the
plant completely!!
