For the sake of having fun with both sides of the issue, I'll play plastic pot advocate:-). Keep in mind I can only speak from my personal experience of growing tropicals in containers here in Oklahoma over the last 30 or so years. What works for you somewhere else in the world may trump anything I might say. All plastic pots is a stretch :-). I use the Rootmaker inc. plastic pot which probably is the best plastic pot in the world. The one gallon pot has 28 holes (actually 56 with 2 side by side) in it and it dries out faster than your clay pots. I've done side by side tests with a decent number of plants to see. The black plastic Rootmaker 1 with the predrilled holes all around the container dry out faster than a red clay pot of similar size in full sun. I grow almost exclusively in plastic. Big plants weigh too much on their own even without the clay pot. I will put some specimen Adenium down the road in very nice very shallow ceramic pots. If I want an adenium to develop a more shallow and wider root span, I'll take a 10 inch hanging basket (I have a bunch of used ones laying around) and drill 1/4 inch holes in it for faster drainage. The 20-30 holes will be on the bottom and on the sides maybe an 1/8 inch above where the bottom of the pot is. With bulb pans I dont bother. I can make a plastic pot drain much better and faster "easier" than I can modify a clay pot. A modified plastic pot can give you a good run for your money. I've got literally hundreds of clay pots I bought at a garage sale about 15 years ago that I don't use. As far as adeniums overpotted, no matter the pot make up, they will rot if grown in marginal soil. Crappy soil is crappy soil. A pot will not make the difference. Personally I think soil is the most important part of what we do with plants outside of care. Containers or container sizes are probably next. 3 years ago I skimped on soil with a bunch of adeniums because money was tight and I paid a huge price. Over half rotted and many were slow to recover. A few with nice blooms I rerooted after I lost most of the root system. I just don't loose adeniums with good soil. Never have and hopefully never will :-). I can put a nice adenium in crappy soil and kill it over the winter unless I'm totally focused on that plant and watch it very close. I can put a another nice adenium in a great soil mix and rarely have to focus as intensely on it as I do the one in crappy soil. Bad soils can hide rot problems sometimes until it's too late. Good soils with good care hide nothing. There's nothing to hide. randy

Since no one has replied yet, I'll take an educated guess and say that it's fine. I used granular time-release fertilizer on all of my houseplants, including palms. The bamboo palm is a fairly easy to take care of, so I don't think you have anything to worry about. When it comes to palms, I like to make sure the fertilizer I use has magnesium in it, since some species are very hungry for it!

I was able to get 150 lb. Of Osmocote fairly low priced at a nursery auction and used it for tunnel grown tomatoes among other potted plants. I worked it into the preplant soil and the following year I could still see intact pellets. Someone related that those pellets probably had fertilizer leaches out. I just don't know. I would say it is compatible in price to many organic fertilizers for extended nutrient availability when you compare nutrient content. I would expect that future fertilizers with incorporate this technology for all types of crops. The research results I have seen for potted flowers is overwhelmingly in favor of using it. Even water soluble Miracle Grow just did not get the desired response.

Could someone explain the benefits of foliar spraying fish emulsion? Plants take up nutrients best through the soil from the roots, not the leaves. Use of organic fertilizers in containers with fast draining soilless media seems unnecessary to me and probably wasteful. Fish emulsion also has excessive nitrogen (5-2-2 or 2.5-1-1). Using it on plants in ground I can understand, but is it really a good idea for containers?
