Did you ever think of using... Carex?
 
Five Carex
l-r: 'Bowles Golden', 'Ice Dance', C. glauca,
C. stricta and C. pensylvanica

Common name

Sedge

 

Varieties:

Carex elata 'Bowles Golden' Graceful clumps of thin, bright gold foliage bloom in May. Needs moist soil in full sun where it will have the best color.  Tolerates somewhat drier conditions in part shade. It will grow about 2'x2'. 

 

C. morrowii 'Ice Dance' 12" tall with white variegation ½" wide blades. Foliage is crisp and neat. Evergreen clumps spread nicely.

    

C. glauca (C. flacca) Blue Sedge is an evergreen clumping grass with a steel blue color, 9-12". Spreads slow and steady forming a nice groundcover for full sun to light shade. Very drought tolerant.

 

C.stricta (Tussock Sedge) Rich green, fine textured, evergreen

foliage 3' x 3'. Tolerates standing water. Native.

 

C. pensylvanica (Pennsylvania or Oak Sedge) Bright green, narrow arching, semi-evergreen blades 10" long, native  to eastern North America. Durable species  tolerating sun and shade. It can even become a mowable groundcover! Native.

   

Carex best attributes

Considered by Rick Darke to be "too little known and too little used in the garden". The flowers are not very significant, but the foliage easily makes up for that.  Soft arching blades range in color from green to gold to blue and even variegated. Great as a groundcover, garden accent, window boxes and pots. Also a nice choice for modern landscapes. 

 

Cultural requirements

Sun to part shade.  Many can tolerate wet feet but will also grow in drier conditions. Generally speaking, deciduous Carex should be cut back in spring and evergreen/semi-evergreen varieties should be cut back occasionally in late spring to clean up older foliage.

 

Pick up a copy of Rick Darke's Pocket Guide to Ornamental Grasses and read about each individual Sedge. It's an interesting guide and guaranteed to give you lots of  ideas and the desire to have more grasses! 

 

Thanks Liz! 

Question of the Week

 

"There is a lot of conflicting info on the web regarding fertilizing boxwood. What is the correct fertilizer to use, how much and how often?"

Submitted by Lise from Outdooor Environments

Sea of Boxwood 

Mark answers:  It is not so much the kind of fertilizer you use as it is the conditions in which the boxwood have been planted and 
the pH of the soil.

 

The pH should be 6.5 to 7 with some literature claiming up to 7.5. This will assure the fertilizer is available to the plant.  So if you have been using something that acidifies the soil you probably have pH range that is well below 6.5 and the plant can't get the fertilizer. The only way to know the soil's pH is to do a soil test. (We have brochures from UCONN and the Ag. Experiment Station explaining the proceedure and where to send the samples. We also have soil probes if needed so as not to disturb the beds too much.)

 

Next, and this is a big one, Boxwood are shallow rooted plants. They do NOT like being planted deep especially in heavy, wet, clay soil. These conditions limit oxygen getting to the roots and thus the plant cannot carry on respiration (the process of burning sugars to release energy needed for growth) always plant a little high in these soils (after you make some attempt to amend them) remember you can always add water but you can't add oxygen if they are deep in a clay soil.

 

If they are planted properly Boxwood benefit greatly from a little mulch as it helps cool the roots. But excessive mulch and leaf debris from clipping and shearing can lead to fungus cankers rotting the bark and phloem and mice or voles chewing the bark and phloem off, in both cases leaving dead branches that are unsightly flags.  

 

Now that you have corrected all the other issues that affect the health of Boxwood you are now ready to fertilize them. I like a product such as Lebanon's 9-2-5 Organic Base with 6% Iron and since Boxwood are planted for their evergreen foliage, this product will excel in providing dark green color since iron is needed in the process for making chlorophyll. Espoma's Iron-tone has iron and sulfur which will acidify (lower the pH) the soil, if that is needed. The same goes for Holly-tone and PHC 4-3-3. These will acidify the soil and should only be used if a soil test shows a pH above 7.5 (alkaline). Another point on the 9-2-5 is that it is organic-based and has MESA slow release fertilizer making its potential for "salt burn" very low and this is important with shallow rooted plants like boxwood.

 

Here is an excellent overview on Boxwood culture from the National Arboretum. It's worth a read.
