Carex dying out in center

15 years ago

One of my favorite foliage plants is Carex Evergold. Having a problem tho. Every care note I've read says you are supposed to cut back last yrs foliage in the early spring to allow new foliage to appear - like other grasses. Every yr I forget that I did this - and every yr it takes forever for the new growth to appear, and some of them die out in the center of the plant leaving a big brown chopped off spot in the middle. I always thought this was a shade tolerant plant and I've used it to underplant a number of larger spring things like peonies, astilbe, hellebores.

Now I read on Santa Rosa Gardens website that Carex should be a sun plant planted in moist almost boggy summer conditions with dry care in the winter if its deciduous.

Thats kind of hard to produce since here in the midwest its dry in summer and wet in winter.

Anybody having great long term luck w Carex - esp Evergold? I really love this plant and think its gorgeous all summer and vastly underused.

Like you, I love this plant. I never cut back the foliage because I thought you weren't supposed to do that. I have always used it in the shade too...somewhat dry shade....definitely not wet. This year, I planted three in sun after seeing them thriving in full sun in another garden. The ones in the sun have grown very well and they are in damp soil...where siberian iris thrive and almost do too well. I'll be curious to see how they do in the long run...like over the winter. I always think..."carex...sedge...water", but I'm not sure if they will tolerate really wet areas (of course I haven't tried this). In my yard they seem to last forever, and have been great at lighting up dark areas. I will try to post 2 photos..the new ones in sun and some older (5-7 years) in shade.

It's borderline hardy for you, so that may explain why it's not thriving as you'd expect. It is fully evergreen in warmer climates and is generally NOT cut back. It prefers some shade but will grow in full sun if moisture issues are correctly addressed. Like most carex species, it likes evenly moist soils and will even tolerate quite damp conditions, especially during the heat of summer, but would prefer good winter drainage conditions. It will not tolerate excessive heat or summer dryness.

Carex is a cool season grass and if you do cut back, it needs to be early enough in the season to allow for regrowth before the heat of summer pushes it to dormancy. OG authorities Darke and Greenlee suggest cutting back to no less that 4-5 inches in late winter if you have to.

Cucumber seedlings suddenly dying out

Where are you located ? what have been the temperatures like ? Cucumbers, generally, cannot tolerate cold. They are more cold sensitive than peppers and eggplants, more like basil. I have killed more cucumbers and basil than anything else, due to cold weather and itching to plant out.

Coleus Mini-garden 'Tree' dying out in center
Q

As soils become heavier (more water retentive), they are more difficult to grow in, they require greater skill/care with regard to watering habits, and the variety of plants you can bring along living happily side my side diminishes; while in a highly aerated soil that drains freely and doesn't support a soggy layer at the bottom of the pot, you can readily grow succulents (sedum) and coleus side by side. When using heavy soils, the problem also becomes more pronounced as the container gets shallower. This is because in a 12" deep container, a soil that supports a 3" deep soggy layer is only 25% saturated after a thorough watering, while a 4" deep container, using the same soil, is 75% saturated and a 3" deep container is 100% saturated after a thorough watering - not really conducive to growth for any plants, much less those that don't appreciate wet feet. As to why the center is dying out of your coleus, we'd probably need a picture to get a better idea. I'm going to link you to a thread that will help you deal with excess water retention. If you find it interesting or helpful, and you want to learn more, just ask, and I'll link you to a thread that explains how water behaves in container soils. I think an understanding of that concept represents the largest step forward a container gardener can take at any one time ..... except perhaps the first time you actually got your hands dirty. ;-) You would normally consider a container only 1.5 - 2" deep a poor choice for cacti & succulents, but the right soil makes it easy.

OK, I will attempt to divide and be more vigilant about trimming. Gardengal, is this kind of center dieback what you see as a result of environmental condition, and that can't be helped by cultivation? I don't think this is a case of the soil staying wet as it is practically sand under the pavers.

Which carex are these?
Q
Comments (5)
Thanks everyone! I'm mainly asking because I'm wanting to use the right drip irrigation settings. Some carex seem to be bog plants, and others drought tolerant after they are "established ". These are on the same station with rosemary and nandina, under redwoods in dry sort of dappled shade, but sometimes scorching sun. There are also a few heuchera, foxtail fern, a New Zealand flax, and a maple (Bloodgood?) , and those are mostly in shade. I really like the plant in the second picture, but the ones in the first picture, not so much.

Thanks for the feedback. I'm going to move the ones I've got and divide them to get rid of the dead centers. If Darke (assuming Rick Darke) says cut back to 4-5" I will listen - love his books. I was cutting them to about 2" and I just went back to Bluestone's website and they have now amended their care instructions to tease out dead blades as needed in spring. I'm sure that is not what it said before - but that's ok. I got my first plants from them a few yrs ago and have continued to add them around the garden. Its just a great plant.

I grow this carex here in the hot-as-blazes south, but in a lathe house. It does extremely well for me in consistently moist conditions, as was said. Gardengal, when do you divide it? Is there a method other than the usual dig up the clump and slice it? I really love this plant and would like more of it. For my money, the carex family has some of the loveliest foliage plants around!
