Another question regarding Courtyard Villa backyard (pics)
 

Still working on the backyard.

Should we let the vines grow into each other (pic 1) or keep them trimmed (pic 2).

I don't want it too look even more 'busy' with all the flowers already out there.

I have lived in CYV's since 2007. In my opinion you are making a huge mistake having any vegetation growing up your walls (or home). Your walls and home will need to be power washed at least once a year, perhaps twice or algae will grow on them. You cannot keep your walls clean with vines growing up them. Don't forget that in Florida plants grow 365 days a year...we really don't have a winter season!

Tear it out now while it is still manageable.

A maintenance mess that does not improve the appearance at all.
Bugs and critters too.

Bingo, there's the winner

Although it looks lovely right now, it's not likely to remain lovely (as the other posters have pointed out). On top of that - if it starts growing over the fence onto your neighbor's side of the fence, they might choose to use a weedkiller to get rid of it. And that'll kill your plant.

Picture 3, remove or you’ll have a mess

Wow, I guess people don’t like it. We have not added any plants to our Villa. The back is still just grass and we currently have not plans to. This is your backyard and you can do things you like. Based on what others have said, it might be easier to stay with picture 2 and keep things trimmed up nice and neat. Good luck.

I have the white fence in back yard and I say let them grow together. I get tired of looking at that white fence.

Well, as previously stated, your neighbor may not mind looking at a white fence and have every right to remove anything that comes on their side of the fence

I actually like the look of the vine growing together, however, in FLA, the vines will grow out of control. Maintenance will be a nightmare in a year or two.

Plant your bushes close together, trees near a sprinkler line, and of course vines on the side of your home or fence...forget everything your learned from the last 50 plus years about vegetation growing out of control and causing expensive repairs and removal...as some say , " more money than brains" . I am blessed you are not my neighbor and just someone I sit next to in a bar.

If you love the greenery/hate the stark look of the fence, why not move your trellises out far enough to trim behind them as your vines grow creating a wall?

Depends what you like but my preference would be to keep them separate and have the break of the nice whit fence in between.

Vines on walls
 

I agree that the vines will make a mess when you need to power wash your walls. Why don't you consider getting some outdoor metal wall decorations that you can remove when you need to power wash the wall.

If you google outdoor metal art for walls you will find many suggetsions.

White fence will grow green and black mold especially behind the vines in the shade. It will be impossible to pressure wash and will be an eyesore and over time will degrade the plastic fencing so on removal The fence will have to be replaced. Moving thr trellis forward so as to have room to pressure wash fence is best option if you insist on keeping the vines.. With age comes wisdom (hopefully)
