Back in my experimenting days I used soap on my roses at about 2-3 tablespoons per gallon of water and defoliated some of the more tender ones. I would be careful with the soap. Rose grower use a "water wand" to get rid of spidermites on roses. Just use a stonger jet of water on the under sides of the leaves every other day for 10 to 14 days. It doesn't kill them right away but it messes up thier life cycle and they eventually die.

Averyb, are your hibs getting full sunlight? Are they in or outdoors for summer? Hibs do best outdoors in summer, sitting in full sun..though if you do this, make sure to acclimate first..otherwise leaves will burn. If you can't place outside, set in a south window..if you don't have south, use a west. Did you also buy Hidden Valley's soil? Water the soil thoroughly, but let dry a bit between waterings..Don't keep soil soggy. Also, make sure soil has good drainage. Does your pot have drainage holes? Also, did you repot? If so, what size did you pot from and to? You don't want to overpot. I buy Hib food at Plumeria people..been using if for yrs..it's a pellet food..just sprinkle on soil then water. Are your hibs getting humidity? If not, mist foliage, daily. How tall are your trees? Toni

Sounds like you have insect problem.

there are lots of annoying green worm pests that get into my buds not sure the best option for treating them...likely if you can get them as eggs before they burrow that would be best. likely something akin to cutworms...
