Please what can I do to encourage Indigo Bees to my garden I have been trying for a week ha . Any suggestions. Thanks

This unfortunately happens sometimes when transitioning from one Bee colour to the next one (it happened to me between orange & yellow and I almost gave up). But you have successfully reached Indigo so you must have understood by now that there isn't much you can do to influence what Bees are coming.

You can only slightly improve your chances by either adding another table of food (I believe you would have done that already, if you could) or babysit your garden and discard any hive that starts with a Blue bee. Only accept an Indigo bee as a first and then you might get lucky and get a 2nd by the end. That way you will progress to a flower with 2 Indigo petals and it should (in theory) get easier after that.

It is a slow process. The next step is to get a beehive with two indigo bees.
I would discard the beehive if you get a blue bee first. If the beehive starts with an indigo bee, then the chances are higher to get a second indigo bee. I discarded lots of beehives throughout this challenge ;-)

Much thanks to you both, I’ll press on.

where did you get your beehive from to start?
