I am sorry if this has been answered already, I have been searching all over. My sprouts have been mature for days now, some at 90 days. Is there something I am missing? Is the coin no longer active or something or did I miss an update somewhere? I have been watching for any change in the past few days. So far nothing has been happening.
I've just successfully staked 10 million in 5 days. As a rough rule of thumb, the more you have the quicker it takes to stake. Anything between 200,000 to 1 million should stake within a reasonable amount of time. I've had much smaller stakes mint quickly, but that was months ago when I just started with Sprouts.
So to answer your question:
- make sure that you open your wallet for staking, otherwise it won't happen. I know this is basic, but I notice that you are a newbie with only one post; and
- acquire a decent amount - Sprouts are cheap enough to buy at the moment. 1 million should stake reasonably quickly before too long.
The minting tab should give you a clue. If it says that it is 100% (or close to 100%) certain that staking will occur within 24 hours, then it will - usually within a few hours.
Difficulty has been increasing due to more blocks trying to stake,
If it was me I would use coin control and recombine all of your coins into only 1 block.
(This will reset your coin age, but if they have not staked in 90 days , you might be waiting a year or more.)
FYI:
Anyone that needs it can get a Current Sprouts Bootstrap.dat (dated 2016-2-28) from my new bootstrap service at
https://bt.irlbtc.com/view/1378653.msg14024451#msg14024451It is stored in a Rar format so it is less than half the size of a zip file.

This Bootstrap service is basically free, we would appreciate it if the people running the OPs would place a link to us , that frees them from the tedious work of keeping a bootstrap updated where they can focus their time on more important matters, and in exchange we will update their Bootstrap on a monthly basis.
