My coneflowers curl downwards as they grow up but face up while in bloom so I wouldn't worry about them. The yellow leaves on the catmint is a sign of root damage, more than likely too much water so rise it up first. If your original soil doesn't drain well you should always plant on top of it and build mounds of good soil around the plants (sort of a raised bed without walls). If the area has some slope to it you can also dig little trenches to drain the bowls of clay under the plants. Sitting in water is bad for most plants. If its been as wet as you say these guys have probably not grown a lot of roots so go ahead and dig them up. Keep in mind that the roots will eventually be longer than they were in the pot so you want to really mound them up high. Also keep in mind that both cone flowers and catmint don't need extra rich soil, just normal garden soil will do. Some of them bloom better in poor soil.

By the structure of some gingers & heliconias plant cells , they do not store the water and therefore do not support to be moved without damage - cut the old foliage and just be patient until new roots grow ! Its why most of ginger & heliconias grow well near by the stream !

I've taken an interest in learning about Florida gardening because I plan to move down there eventually. What I've read again and again about discouraging nematodes is to maintain a heavy layer of organic mulch. This will eventually break down and improve your soil. Some people mix in cheap clay kitty litter to make their soil heavier. Another possibility is to heavily underplant roses with Marigolds. There is one seed strain of French Marigolds in particular which tested as being very effective at deterring root-knot nematodes -- Tagetes patula 'Ground Control' (aka 'Single Gold'). The one caveat is that the effects won't be seen until the following year, and to maintain the effect, you'll want to replant them every year. As far as planting too deep -- I think many here would say I am guilty of this, but there hasn't been any negative effect which I can see. When I was putting this garden together, I planted my roses (own-root bands that were grown-on in pots for a few months) directly into the native soil in late Summer 2013. Prior to planting them, I had laid down sheets of cardboard to smother weeds and grass, and covered that with trimmings from a tree I was cutting back. This accumulated to about three inches, but it was a very "airy" three inches. Over all that, I put down an additional 6-8" of "proper" mulch (partially composted shredded wood chips). At first, I made concave "dishes" around each rose to allow water to be directed towards their roots and keep mulch away from the canes as I kept reading I was supposed to do, but after the first Winter, the beds were pretty much leveled out. In Spring, I worked an additional 2" of composted manure into that layer of mulch. This meant that what was once the border between canes and roots was now about 8-10" below the surface. Why did I do this? I wanted to give the roses an "early start" on having deep roots for getting water, and anticipated that canes buried beneath the mulch line would eventually root further up, allowing for easier access to fertilizer applied at the surface. Companion perennials were planted directly into this "mulch/compost" layer in Spring 2014, and they grew like gangbusters in their first year. Last Autumn, I wanted to continue adding organic matter to the beds, so I "harvested" fallen tree leaves and spread them to a "fluffy" three inches thick. I also started collecting used coffee grounds from Starbucks -- one 13gal kitchen garbage can-full per day -- and spread this about 2-3" over the leaves. It took about three months to complete. Winter snow has packed this down a bit, and the previous year's additions have started breaking down, so where I'm at now is about where I was after the first layer of mulch -- about 6-8" above the original soil line. This week, I started some early pruning. While there is some snow still remaining in half of the garden, where it is gone there was already life in the top layer of coffee grounds and leaves -- various soil critters are waking up and finding lots of food waiting for them. I've noticed some freeze damage (naturally) on some rose canes, but nothing soft and mushy which would indicate "cane rot". True, this could emerge later in the season, but I also never saw it last Spring when the roses' canes were also buried to about the same level. Why is this not harming my roses? Perhaps because what's covering the canes is actively being broken down by the various organisms in the soil, and that process is different than simply being a blanket of "wet" around the rose canes. Worms and critters keep moving the material around, and fungi digesting the material are sopping up the extra moisture. I don't know for sure -- all I can say is that I don't see any negative effects. :-) ~Christopher

The reason you would want to plant it deeper is to protect the bud union from winterkill by burying it underground. If the scion (top part of the graft) is fine after this past winter, it probably doesn't need protection. If it isn't, you've lost the rose and just have rootstock. Either way, you don't get anywhere by replanting it now.
