SUMMER!! ;o)

I would say no to these. It looks like sun/slug/pest damage to me.

none of them has nems ..

you dont water enough ... whatever you do.. its NOT enough ...

i have been in drought for 6 weeks.. using drip irrigation.. and have been watering 14 hours a day for the last 3 weeks ... on pure sand ... do you think you are close to what i am providing??? ... and mine are still looking like yours in poor locations ...

go in between plants.. and dig a hole one foot round.. and one foot deep ... and this will tell you how much water.. YOU ARE PUTTING DOWN AT THE ROOT LEVEL .... start watering heavily ... and dig a second hole in a week.. and see if you got water 1 foot down.. if not.. increase water again .. and dig third hole in another week ...

increase water by 2 inches per week... and see if you can get the new flush to come out blazing ...

NOW IS THE TIME THAT HOSTA ARE STORING FOOD.. IN NEW ROOTS.. TO HAVE SAID ENERGY IN SPRING.. hosta come up on that stored energy ..

if your hosta are stressing out this time of year... and basically sacrificing food making machines knows as leaves.. then they are not able to store max food for next year ...

increase water ... and you will be rewarded next spring ...

the alternative is to put your hose on a trickle.. and do one hour at each plant ...

good luck
