Sensoji, Asakusa - Demboin Gardens

Hi.
I understand I need to apply in advance to visit the gardens.
1) Is it worth a visit ?
2) How do I go about with the application ?
Thanks.

The last thing I heard is that they do not show the garden to anybody anymore. But I am not 100% sure if this is accurate.

You are able to enter the Denbouin Garden for a limited time special. Admission period is March 14 to May 7. 10:00 to 16:30 every day(Last admission 16:00). The admission fee is 300 yen.

Many thanks for the information.
Guess I will not be able to see it as I will only be in Tokyo 20-24 May - what a pity.
Cheers.
