Chiming in for my own interest as well as to offer a suggestion. Warning: I am a novice - my advice might be detrimental! Hopefully, those with greater expertise can chime in and offer an opinion. I put in a 12 x 10 pond years ago. Did it on the cheap. I used the thickest black plastic on a roll I could find. It is not unlike painter's drop clothes only a lot thicker. Every 2-3 years I have to replace it due to it wearing out or getting holes poked in it by my kids playing around. It was $30 or so for a monstrous roll I still haven't used completely. Why not drain down the pond, muck it out, layer the pond with the cheap liner and see what happens? Full disclosure - I go to the local pet store and buy 25-cent goldfish. The sales people are usually good about letting me select a combination of different markings so my gene pool is diverse. I started with four and had it quickly grow to 40-ish fish. For a while I fed them but found out one winter I didn't have to - I was hospitalized and too infirm to care for them and they survived on the nutrients in the pond. Trees grew over the pond in time and they would muck up the bottom and clog my submersible pumps. Eventually, the shade countered the algae growth and I didn't need to replace the pumps. A small number of plants in pots that were weighted to stay submerge provided a small amount of cover. A shrub rooted near the pond and branches dangled to the ponds surface. I trimmed them but left the shrub for shade/protection. The problems were not health of the water or the fish or the plants. The problems were related to leaves filling the pond and "filling it in" substantially each fall. Until Tulsa changed the chemicals in its water supply. The 110+ degree temps and leaks in the thin-ish liner required fillings 2-3 times a week. I forgot for a week and it got really low. The water I added overwhelmed the existing water, and the chemicals wiped out the remaining dozen fish. The plants didn't seem to mind but I now have a muck-covered liner (several layers of it, actually, as I'd just add the new one on top of the other, figuring the old ones would provide some protection from roots poking through). Is that a practical solution? Buy some cheap CHEAP liner. Connect them to cover the bottom of the pond. Drain and muck out the pond, drop the liner and let it fill in. === Or...fill in a big chunk of it and create a new "wall" out of liner with rocks, backfilling with rock, soil, sand, whatever. Plant plants that don't mind wet feet and let them live in a bed next to a much more manageable pond.

I was poised for a photo of rat snakes all waiting for you to toss seed to them.Joking of course.

The areas we night hunted Chad had been to previously. During the day we explored, searching for hogs and anything else that happened to be out in the 85-90 degree weather. Besides the turtles, we saw another recently hit copperhead, a DOR coachwhip, and a ribbon snake in the field. I missed a rough green in the field, which was very frustrating as I seem to otherwise have a DOR curse for the species (which continued through this trip as is evidenced on the list below). We discovered one beautiful drive which proved that the suspected resident was indeed in the area. Unfortunately, we were late in crossing his pathI tried to crop a small section of this once handsome specimen to cut out gore: We decided to walk the hillside habitat, but only a large box turtle was aboutÂin different conditions/time of year, this area certainly would have showed us more. By evening, we felt like we needed a break from driving and DORs before cruising that night, so when we came up on a couple of bridges we hopped out to walk around. Not expecting much more than the chance to stretch the legs and dodge poison ivy, I scrambled down under the bridge. After poking around a bit, my eyes crossed the path of this impressive beastÂright in the middle of the creek: We had just been musing about whether we were in cottonmouth range yetÂwe were Western Cottonmouth, Agkistrodon piscivorus leucostoma , no flashÂalthough lacking detail, I liked the texture effect of this shot with flash As we were taking pictures, Chad noticed a small snake submerged not more than a couple feet from the cottonmouth. It turned out to be a blotched water snakeÂwe couldnÂt escape nerodia-less. Rejuvenated, we started the pigmy/pygmy (whichever you prefer) quest. After missing 2 or 3 more rough greens to trucks and semis in front of us, we came over a hill and had to quickly veer to straddle this fellowÂnote the car cresting the hill that would have been his doom. Black rat snake, Elaphe o. obsoleta And then we found him, shining white against the headlights, Mr. Streckeri  a beautiful animal, with an almost orange stripe: Western Pigmy/Pygmy Rattlesnake, Sistrurus miliarius streckeri Awhile later, Chad spied another great animal along the edge of the road. Speckled kingsnake, Lampropeltis getulus holbrooki On the way out, Chad spotted one more pigmy, this time a DOR--my eyes seemed to be done by now and seemed to be on 2-plus foot snake focus. We left the area early (11:00 PM), satisfied with our finds and wanting to get the drive home over with-- This is the list of species seen, as best as I can rememberÂIÂm sure I am forgetting a few: Western Pygmy Rattlesnake, Sistrurus miliarius streckeri 2 (1 DOR) Western Cottonmouth, Agkistrodon piscivorus leucostoma 1 Timber Rattlesnake, Crotalus horridus 1 (DOR) Broad-banded copperhead, Agkistrodon contortrix laticinctus 6 (3 DOR) Northern Scarlet snake, Cemophora coccinea copei 1 (DOR) Speckled kingsnake, Lampropeltis getulus holbrooki 1 Prairie Kingsnake - Lampropeltis c. calligaster 1 (DOR) Black rat snake, Elaphe o. obsoleta 2 (1 DOR) Northern Rough Green snake, Opheodrys a. aestivus 6 (5 DOR) Blotched water snake, Nerodia erythrogaster transversa 1 Bull snake, Pituophis melanoleucus sayi 1 (DOR) Texas brown snake, Storeria dekayi texana 2 Eastern Coachwhip, Masticophis flagellum flagellum 1 (DOR) Prairie Racerunner, Cnemidophorus sexlineatus viridis 6 Northern Fence Lizard, Sceloporus undulatus hyacinthinus 1 Three-toed Box Turtle - Terrapene carolina triunguis (many) Ornate Box Turtle - Terrapene ornata ornate (many) Red-eared Slider - Trachemys scripta elegans 5+ Midland Smooth Softshell - Apalone mutica mutica ? 1 Eastern Snapping Turtle - Chelydra serpentina serpentine (DORs) Southern Leopard Frog - Rana sphenocephala utricularia (hundreds) American Bullfrog - Rana catesbeiana (many) Eastern/Cope's Gray Treefrog - Hyla versicolor/chrysoscelis (many) Woodhouse's Toad - Bufo woodhousii woodhousii Northern Spring Peeper - Pseudacris crucifer crucifer (heard) Western Chorus Frog - Pseudacris triseriata (heard)

Or improperly watered. I've seen more jade plants suffer from too little water than too much. Adding rocks to the bottom does not improve drainage, but only serves to take up space....the rocks reduce the growing area. Your rapid drainage should come from the potting medium itself. Jades and other succulents (all plants, really) do best if watered infrequently but thoroughly. The soil volume should be allowed to dry out, but needs to be completely resaturated on watering day. Little sips encourage permanent dry pockets to form, where roots will die. A coarse textured potting medium ensures that drenching our succulents never causes the problems associated with 'overwatering'. Test for moisture levels by using your fingers to dig down and feel. You can also use a dry, wooden dowel to insert to the bottom to feel for moisture. With experience, you will be able to judge the moisture content of a container by its weight. The roots of jades are shallow. Best scenario is to plant them in a broad, shallow container, then insert the whole pot into a larger, deeper pot for stability. You are the only person who can be the judge of whether your plant has been under or over watered. You may have to unpot to check the condition. I'd evaluate your potting medium, too. I can't tell much from your image.
