I have vaguely read there are some herbs that my adversely affect other plants, but cannot find anything easily using an internet search. My rhubarb has been really struggling for the past few years, and I am wondering if it might be from companion plants. It's in a bed with strawberries, and the herbs in close vicinity are lovage, helenium, fennel, garlic, mugwort, betony, horseradish, comfrey, and rue. Or maybe the rhubarb just mysteriously has become weak, although this came from my mom's yard years ago and has always been quite healthy. Here it is in its prime, spring 2008. It is now merely a scrawny few tiny leaves. I've never done anything special for it, other than mulch and occasionally add seasoned manure to it.

Hi Deb. Rhubarb is a heavy feeder. My read is that it has a lot of company, all draining on the nutrients. Try some Miracle Grow feed. You can hand mix it in a watering can, or apply with a spray attachment. The company would likely benefit from the treatment too.

Deb - have read that rhubarb should be planted shallow. Has the depth of the soil changed since you planted it, say, from compost breaking down?

Cindy, I will check that as well. My plan is to perhaps relocate the rhubarb to another location, give it some really rich soil and be more diligent about weeding and watering. It has mostly been a bit neglected over the years, but always performed well.

Deb - I tend to neglect plants that perform well until they don't. I have a bed of Astilbe that need some TLC as I think they've gotten buried too deep in formerly amended clay covered with lots of shredded leaves. As a rule, I don't feed perennials but they need some looser, amended soil.
