Planting tips for bamboo and grasses!
Before deciding what and where you are going to plant make anassessment of the area. If you can try to do it early in the year so you haveplenty of time to plan ahead.
This is also a good time to determine where the shadow boundaries are. In the early months of the year, the sun is low on thehorizon and the shadows extend further into the garden.
Look out on a brightday and mark the extent of those boundaries with a couple of pegs.
Determiningthese boundaries is quite important as most true grasses relish the sun and dobest when the have maximum exposure to it, even through the winter months. Thisis because grasses including bamboo are incredibly sophisticated plants when it comes to converting sunlight to energy through photosynthesis.
Most grasses including bamboo, with a few exceptions do not generally do well in shade.However sedges and rushes do. Once you have determined the limitations of your boundaries you will have a good idea where grasses and sedges belong.
The exposure to wind and elements will depend to a degree on the of openness ofyour garden. The prevailing winds, coastal conditions, altitude andgeographical location will all have an affect on the microclimate of your garden.
Exposure to wind is probably the most damaging as it can dessicate plants and dry out the soil very quickly even in the winter months. It may bepossible to erect physical windbreaks such as fences or screens, however thereare many bamboos and grasses that stand up extremely well to exposed conditionsand the larger species can be used to good effect on the boundaries to form aquick growing living screen that is far cheaper more attractive and wonderfully animated in the wind when compared to conventional fencing.
Knowing your soil types is essential. I say types as even the smallest garden may have a varietyof different soil compositions and varying PH levels in it. Most grasses andbamboos are unfussy about the PH but there is always the one or two that are, so check the lists above.
Composition of the soil is also important, a shaded area on the north-facing wall of your property may prove to be extremely dry due toits shelter from the prevailing wet weather winds, absorption from thefootings, or excess drainage created by a high proportion of builders rubbleand sand that has been left or backfilled. These conditions are not conduciveto most sedges and in fact not conducive to much at all. The optionshere are to dig out the planting area and isolate the footings by placing apolythene sheet or damp course between the wall footings and then replacing thesoil after it has been much improved with lots of organic manure or compost and possibly riddled as well.
If you also have areas that have a suitable aspect for grasses, but tend to be heavy and wet, then you can improve those areas bydigging in plenty of sharp sand grit or shingle to improve the drainage. Unlikebamboos and sedges grasses don't have a high nutrient requirement in fact manydo best on poor soil so there is no great need to incorporate organic manuresor fertilizers. An excellent way to maintain drainage in these areas is to makea gravel garden where a number of specimen clump forming grasses can be shownoff to advantage within an area of gravel mulch. This will effectively suppressunwanted weeds and the gravel will work its way down over time into the soil and preserve its open structure and drainage.
Bamboos on the other hand do best with a fertile free draining and evenly moist soil. They will however toleratemost condition except to excess. Perhaps their biggest dislikes are waterloggedground and dense shade. Like grasses they do not take a lot of looking after ifplaced in the right spot with their minimum basic requirements plus a hair cut, comb through and brush up and an occasional feed.
The problems to be aware of with bamboos is that some are clumpers and well behaved, ideal for specimenplanting in lawns or as a backdrop for herbaceous perennials. The others arerunners beware some are rampant, such as the staggeringly beautifulChimonobambusa Tumidissinoda from China who like Genghis Kahn with his hoardswill gallop across your lawn and into next doors in no time at all. Thesebamboos are best kept In containers and they do well being shown off andappreciated as such.
