Once you have picked what garden you want, there are many other factors you need to decide before you actually get to work with your gardening tools. Mainly you need to choose its location. This is usually decided by several factors: How you will water it, how much shade it needs, etc. Some of these questions can be very important in deciding whether your garden lives or dies, so don't take them lightly. You need to take each one into special consideration.
Choosing the garden's location within your yard is one of the more important things to decide. You want to choose a location that will provide an ideal climate for the plants in your garden. I don't know what type of garden you're dealing with so I can't give you specific advice, but if you do a Google search for the plant you're dealing with then you'll find a plethora of sites informing you about the perfect conditions for its growing. After this, it's just a matter of finding the most shaded
or most sunny spot in your yard. Another deciding factor is how you plan on watering your garden. If you have a sprinkler system already installed for your grass, then it could be a good idea to put your garden in the middle of your yard. Then it will get watered at the same time, and require no extra work from your part. But if this doesn't provide for a good location for your garden, then you might end up watering it by hose or dragging a sprinkler out there. In this case, just make sure your garden is within the ideal distance for a hose to reach. While this might not seem like a good thing to base the entire location of your garden on, you'll be surprised at how nice it is to plan out in advanced.
Getting the perfect amount of shade for your garden can be a difficult endeavor. Once you have a basic idea for where you want your garden, you might want to watch it and record how many hours it spends in sunlight and how many it spends in shade. Compare your findings to an online web site, and you should be able to determine whether the spot you chose is ideal or not for planting and starting your garden in. Of course the amount will change as the seasons change, but this should give you a good idea of what to basically expect for the rest of the year. If necessary, later you can put up some kind of shade to protect your garden from getting too much sun.
After you've determined the ideal place for your garden and whether it has the right amount of sunlight, and whether you will be able to conveniently water it, you're one step closer to actually starting your garden. Of course there are other factors that I have overlooked here, but mostly you should be able to decide whether your location is good or not based on common sense. Just think: If I were a plant, would I be able to flourish here? If you can honestly answer yes, then I think its time for you to head out to your local gardening store and buy the necessary soil andfertilizer to get started!
Have fun!
