    Hi,

    I am currently growing a single plant (the only one surviving of 25... A cat went throught their way...) of D. dilato-petiolaris, and 5 seedlings of D. ordensis x ?? and well... they aren't growing pretty fast! Both are in 1:1 peat:sand, in a heated terrarium at 80°F and water is near the substrate surface (I know, surely too high, but i haven't find a grid to stack them yet). Although the D.dilato-petiolaris is a survivor still stressed by some agressive events, it is not growing pretty fast... So here is the question: How do you grow your petiolaris-complex sundews?

    I have a beta tank... 6 inch deep 24 inch long and 11 inch tall.. I have 5 3 inch pots on the bottom then that grid that goes over fluorescent lights over the pots. A aquarium heater sits in the bottom in the water at about 98 degrees. The plants (D. ordensis 'Mulligans Lagoon') sit on top the grid potted in 6 inch pots with 2 parts sand 1 part washed peat. I fill the water up to about 1/3 the pot and allow it to fall well below the pots before refilling... Right now though it is warm enough here where I just have the plant sitting on the normal shelves with my other plants. It is currently in bloom also.

    Mine are in terraria, no tray watering. These sit beneath the HID light which warms them during the day. I top water enough to keep the medium moist. At night I remove the terraria and put them in as warm a spot as I can find. I currently am running an 18H daylength to discourage a noticed tendency towards dormancy (hopefully this will work). I use this system Oct - May afterwhich I put the terrariums outside and in tray watering provided the plants are in active growth.

    I use a LFS/pearlite mix, about 50/50 with a tablespoon or 2 of laterite mixed in per pot, along with a topdressing of laterite about 3 cm deep.

    From my very limited experience with seedlings, I too have found them slow growers.

    Hey,
    I dont have huge experience with the petiolaris complex. I do grow D. petiolaris and D. falconeri. I have grown my D. petiolaris plants from seed twice now. I have good germination rates if I give them LOTS OF HEAT. I tried germinating them in the winter, and it took about 4 months. Mine grow faster if 1) I give them lots of heat(plant in summer) and 2) I planted them in milled LFS. I have them all right up to the lights. I love the whole complex! They are cool plants.

    I grow mine in plastic boxes under fluorescent lights, 15 hour photoperiod. No lids, trays are open to the air. Media is mostly thoroughly rinsed peat moss with about 10% silica sand. I keep water in the trays so the bottom 1/4 inch of the pots are in the water. Sometimes I enclose some of them in ziploc plastic bags but with the pots just damp, no water to sit in. I am curently caring for D. ordensis, D. falconeri, D. paradoxa, and D. dilatatopetiolaris.

    My indestructible D.Petiolaris.


    This little plant has had a rough time.He was grown from seed and was the sole plant that sprouted after about 8 months. I was surprised to see some thing sprout after so long of a time. In fact I was so excited that I reached in the tank to pick him up for a good look and knocked over the container. I had to dig and find him in the mess. He was replanted into a bowel terrarium. After a couple months I went on vacation and my wife over watered him. I came home and he had been covered in water for a week. I poured out the extra water and he recovered. Then lastly my parrot attacked the bowel terrarium, he was uprooted in the attack. I was sure he was done for but replanted him into a 4 inch pot. I moved him into a terrarium with my other Drosera and yet again he has recovered and is growing faster then ever.

    Lol seedling, and I was thinking that a bad cat attack and a hard sunstroke was a real bad time for my plant... wow! You got worse than me on this one :P Even though, your one is better looking than my dilato-petiolaris [img]http://www.**********.com/iB_html312/non-cgi/emoticons/tounge.gif[/img] I will try the LFS media and see the results [img]http://www.**********.com/iB_html312/non-cgi/emoticons/smile.gif[/img]

    I grow my petiolaris dews outdoors year-round in a sealed terrarium. I have been able to grow Drosera paradoxa from seed to 3in plants in around 6-8 months.
