I have the following seedlings/starts.
1)Agastache 'Blue Boa" 5" tall. not stretched, has first flower!
2) Agastache 'Blue Fortune' 2" tall
3) Agastache 'Black Adder' was 4" tall, leaves mottled and discolored (reddish) and fell off, basal leaves seem fine
4)Agastache rupestris 5" tall, not stretched
Which ones can I cut back? They will need to stay indoors about t2-3 weeks until warmer than upper 40s nite and low 60s day. Have not been hardened off...zone 7b.
Any ideas what happened to Black Adder? All flats kept in same location and treated same (light, water, 60 - 70 degrees)
Pic 1 'blue Fortune. Black Adder in middle, and rupestris
Pic 2 Day two of Black Adder leaf fall
Pic 3 & 4 day 5, what is left of Black Adder. Will they come back?
Should I cut off main stalk?
Thanks for any advice.
Judy
