As people age we try to find activities that will help retain movement. However, many times we can easily over do it and end up straining a muscle or falling and breaking a bone. One common ailment among the elderly is joint pain. What are our options? We need to keep active without causing ourselves pain or injury. Gardening is the perfect solution to the problem.
Gardening will help keep all joints moving and active. It is also a very low impact activity so it will be unlikely to cause damage to muscles or joints. Working in the garden has many other health benefits as well. For instance, it allows for some time in the sun and fresh air. These are necessary for good 
health.
Another good thing about keeping a garden is that there is little pressure to continue if fatigue or illness sets in. There is no set time one must spend in the garden. Therefore we can spend as much or as little time as we feel is healthy for us. It can be broken up and accomplished in the cooler parts of the day to prevent overheating.
Gardening will involve every muscle group in the body. It will also require every single joint to make some sort of movement. Just walking out in the garden in the evening and enjoying the beauty is a health benefit of having our own garden.
Start small, and keep it a manageable size. This will ensure you can stay at it longer. If you choose a vegetable garden that has another whole set of healthy benefits.

The natural stuff is just as adept as the store purchased chemical variety anyway, if you know how to prepare the correct potion.
