Bill Wardwell had good sound advice for beginning photographers. Let me add
a few things.
1. Definitely give Fuji Velvia film at ISO 50 or 200 a try. I use nothing
else now. Definitely superior color in terms of saturation and hue. I buy
the film with Fuji processing included and this insures that the development
is properly carried out. Pictures are returned in about 2 weeks.
2. For closeup photography, a single-lens reflex camera is a must. With
single-lens reflex, what you see is what you get, including focus. Cameras
with separate viewfinders are not suitable for closeups because at that
distance, the viewfinder does not see what the lens sees. Try looking at
your computer screen closing first one eye, then the other, and you'll see
what I mean. The pros call this phenomenon "parallax." That is why you got
only partial blooms. Also, the lenses of many viewfinder cameras have only
a fixed focus, which covers most "snapshot" situtations, but not closeups.
All lenses have a minimum focal distance, no matter what their purpose. If
you get closer than that, autofocus or no, you get an out-of-focus picture.
Again the advantage of the single-lens reflex camera is that you can see
when this happens and pull the camera back until focus is re-established.
3. Buy a short, paperback book on general photography. Your local camera
store can guide you. Or, better still, use the winter to take a basic
photography course at a local community college or university.
4. Find a local, experienced, amateur photographer who can advise you about
your particular camera and situation. People will try to help over the
internet, but your original message had too little information to allow
others to provide more than generalities. You need someone on the ground
with you.
5. Changing cameras will not help unless you are willing to experiment and
learn about your new camera (or your old one, for that matter). You have a
good five or six months till the bloom season to become proficient in using
whatever equipment you end up with.

"I know many children to whom I would fain make a present on some one of
their birthdays, but they are so far gone in the luxury of presents--have
such perfect museums of costly ones--that it would absorb my entire earnings
for a year to buy them something which would not be beneath their notice."
--Henry David Thoreau, Journals, Nov.5, 1855.
