Yes. You can leave them on or prune them off.
]]>I would wait to fertilize until the following spring. That way you won’t risk burning tender young roots.
]]>Try Japanese forest grass, Brunnera, Corydalis, or salvias.
]]>Do you mean ‘Bombshell’? I have two of these hydrangeas and so far they have been blooming for me for the past two years but I have read others have had mixed reviews on this one.
]]>I would insulate the pot by wrapping it with layers of bubble wrap or burying the pot up to its top rim in the garden or compost pile. Though these plants are hardy in VA, they may not survive if their roots are left exposed in a pot.
]]>Could be a weather-related issue or perhaps drought stress. If they were full-sized in the past, I wouldn’t work about it moving forward. Probably just an “off” year for the plants. Fertilize with a complete organic granular fertilizer in the spring to boost bloom production on paniculatas.
