I have several 20 year old Forsythia bushes (14) about 1/2 are not blooming, and haven't for 2 years. I've cut them back to 8 inches and they continue to grow sending out new growth but no or few blooms. Is there anything I can do to encourage blooms for next year. Or do I need to dig them out? Everything has a beginning, middle and an end?

2 questions 1. Ive been told that the spice bush is an understory bush and also that it needs full sun. Which is accurate? 2. Ive been growing swamp milkweed but have had a black and orange bug infestation the last several years. How best to deal with this? We have an organic butterfly and bee garden. To be honest, I'm ready to pull out the milkweed.

Trimming Arborvitae Branches back to Trunk

(I had to duplicate my post because I typed my email address wrong the first time and was unable to edit. This submission has the correct email address). I have what I believe is a large arborvitae growing against my garage. It’s maybe about 12-13 feet tall. It’s on the west corner of my vegetable garden and it blocks several hours of sun, so I’d like to cut it somehow. Removing it all together isn’t an option, but I was considering removing all the branches from the bottom 6 or 7 feet, leaving it in a kindof deciduous shape. My hope was that this would allow a couple more hours of sunlight to the garden. But I’m afraid that cutting this much off will damage or kill the shrub. Can you tell me if this is possible? Thanks! ~Sarah.

My previously beautiful tall fescue grass took a major beating by dogs this winter because the yard never froze. When can I reseed and do I use straw over the top of it. I do realize that I will have to limit dogs on that area until grass is sturdy again.
