Well the general rule in container gardening is that the containers must have some form of drainage. Otherwise the water collects in the bottom, you get ponding of the water, bacterial growth, and root rot. I can't really picture containers made from "wire forms and concrete". That would be quite unusual IME but I would be worried about that weight on the field interfering with drainage in the field. Given all the drainage problems and shallow drain fields one reads about in many parts of Florida, especially with sandy soil, I'd be very reluctant to alter my septic drain field at all. And there are literally thousands of lightweight containers with drainage holes available for gardeners to use that can be easily moved and adjusted for sun exposure without creating problems for the filed. Unlike in-ground gardening Container Gardening has its own set of unique needs so I'd suggest some in-depth reading over on the Container Gardening forum here. Dave

Tibs is absolutely correct. It really depends on the design of the system and how it is supposed to work. There are lots of different ways these are designed and are almost always based on standards set by the state and approved locally. That means that in some areas or some states, almost every "drain field" is very similar in design which can lead to accurate generalizations that you can do "this" or can do "that". But, you really don't know unless you find out from the designer (engineer or sanitarian) and/or the local health department who should know the design of that particular system, what is required for it to function properly, and what the legal requirements are for it. Anything else is speculation. If there is a failure of the system, things that you have done can be blamed for contributing to that failure whether or not they actually did, so it is important to document what you are told and who told it to you.

erm, that is why they are called 'ground-cover' roses, also known as procumbent roses - they are meant to 'flop' on the ground. Rest assured, the rose will be completely happy lying on the floor - the flowers will still raise their faces to the sun and the stems will be quite OK about being prostrate. It is a fruitless and annoying task, attempting to train plants against their natures but, if you are still unhappy, then pop a few pea sticks or woody prunings around the plant and let the stems mingle with the woody supports which will quickly become invisible. There are also various wire supports on the market which will keep the plant more upright.....but I suggest you look for another more upstanding plant such as a neat little floribunda or polyantha.
