First welcome to the site.
To answer your question get a sturdy tripod, seems the obvious answer doesn't it? but some arn't as good as they are made out to be. You need to know what weight the tripod is going to support , so weigh your camera( with batteries) -heavest lens- flashgun - battery grip or whatever gear you have as its no good looking at a tripod+head that won't support it. Then make sure the tripod will give support plus extra for any future camera gear you might get
The other thing is when you go to buy, take your gear with you into a shop, check out the tripod FULLY extended with your gear on it to see how stable it actually is. Shutter slap can actully make a tripod move in that position resulting in blurred pictures same as camera shake hand held.
It is far better to spend a bit more on a good tripod as it will serve you for which ever camera you might get in the future. Also consider if you will be carrying it about much with landscape photography as they can be a bit heavy during a days shoot. They are something you keep whatever goes onto it so its well worth getting a good one at the outset.
I had a cheap tripod and thought it was great until I spent out on a more sturdy one and I sure noticed the difference.
For some guidance I went for the Manfrotto 055XPROB with a Manfrotto 322RC2 head, it is a bit on the heavy side but it is ROCK solid even in wind. Some tripods may require a weight suspended from them to steady.
Also it has quick release plates to attach/ unattach the camera to the tripod, no unscrewing each time to add/remove camera to tripod. That head has a pistol grip for quick easy camera adjustments when the camera is on the tripod.
There are equally as good other makes out there, its just that I am more than happy with that arrangement.
Hope this is of some help as I can't see what camera/equipment you own.
