It's a bit like buying a sports car and driving only in second gear.
But the kit lens is not really bad. It will do OK until you can afford something better, and it is good for learning with. If you are using it for landscapes, you will often need to use a narrower aperture, like f8 - and that happens to be where the kit lens is at its best. If you search the site, you will find many fine photos taken with variants of the 18-55 lens.
Down the track, you will probably want to replace it with one of the many good "walkaround" zooms, like the DA 16-85, DA 18-135, Sigma 17-70 C, Tamron 17-50 f2.8 or DA*16-50 f2.8 (to mention just a few options).
But if there really is nothing much left in the budget after buying the camera, what I would suggest in the meantime is that you also get a manual focus prime lens (ie fixed focal length), such as a 28mm, 35mm or 50mm lens. They can be bought very cheaply (less than 60 Euros) and will give you much better image quality than the kit lens, and a faster (wider) maximum aperture (e.g. f1.7 or f2.8). The wider aperture gives you more opportunity to shoot in low light without a flash, and also allows for short depth of field, which can be used creatively. It's also good to learn manual focus and a fixed focal length, to develop your skills. With a prime lens you learn to "see" the image before you lift the camera - and that's a very worthwhile skill to have.
Many landscape photographers love the old Pentax K, M and A series prime lenses (not to mention older screw-mount models). These are all manual focus. The K and M series (and third-party equivalents) have manual aperture setting - which means you need to meter the scene and set the aperture manually. Those with an "A" on the aperture ring (like the Pentax A series) allow the aperture to be set automatically by the camera.
Others here have far more experience with these than I do, but I had a Pentax-A 50mm f1.7 (about 50 Euros) that was fun to use, sharp and produced lovely colours. Good for portraits and landscapes, pets, flowers, anything. If 50mm is too long for a particular scene, photos can be stitched together afterwards with free software to create a panorama. But you might find one of the 28mm f2.8 lenses (there are plenty of different ones) more versatile.
