yes...incorporate more pea size gravel into the potting mix - (poultry grit works great....found at most feed stores)
adeniums have only 2 seasons - wet and dry ..... wet season is the summer months, when the plant is actively growing / dry season are the winter months, when the plant is inactive and dormant ....
when night time lows fall below 10°C (50°F) it is time to get the plant indoors ....
never let adenium freeze - and - never let adenium sit in a saucer of water .....either will kill the plant
when leaves either - fall off, turn yellow, or when leaves stop emerging is when watering & fertilization stops ....withhold water for a full 3 months - then only water equal to the size of the pot (if pot holds about 1 cup, only water about 1 cup) - then wait another 3 months before watering again -
When to prune ?
can prune when plant is dormant - or - just before plant breaks dormancy ...
Personally ....I like to get all the plant maintenance (prune, re-pot, lift caudex) done in early spring ....this will give the plant the rest of the year to recover -
and like I said, adeniums seem to take forever to respond to changes
