It's similar in many neighbourhoods; blossom tasks will become available that some players can't do.
One way to speed up the process is by practising staggered trashing. When you are have completed a blossom task, trash it. After 30 - 40 seconds have elapsed trash another task from the board. Another 30 - 40 seconds trash another task, and so on until you have cleared the board.
Be careful to be looking at the task board when the first new task will arrive; it will be a Blossom task. If it doesn't suit your hood, trash it straight away. In 30 - 40 seconds the next task will arrive; it will again be a Blossom task. Continue trashing each task that pops up until you find one you like. They will all be Blossom tasks provided you have trashed the previous one.
Working that way will save a lot of time.
I hope this helps.
