    My D. adelae looks really bad. The leaves are dry with no dew. It keeps growing new leaves but they look shrivelled. It was fine all year until August or so. It was very hot this year. Above 95 F (many close to 100 F) for over 2 months straight. Almost everything in my small collection was stressed a little but most everything else has recovered. But not the D. adelae. They look pitiful and they are supposed to one of the easiest to grow. What can I do?

    Sorry to hear that your D. adelae is problematic. Off the top of my head, my first guess would be to raise the humidity, and my second suggestion would be to make sure it has pleanty of light. Take care not to disturb the root system, that will set back the plant for months maybe.

    The leaves that experienced those chronically high temperatures may have been damaged to the point of permanently losing their ability to produce dew.

    However, newly-formed leaves should be producing dew. If they are not, the plant may still be recouperating or conditions may still be unfavorable. What is the current temperature, lighting and humidity?

    Temps: 75 to 85 daytime and 60 to 70 at night.
    Humidity: maybe 80% to 90% most days
    Light: bright patio. Full sun morning to noon, filtered for the rest of the day.
    water: tray system

    I received the plants in Feb. this year. They grew like crazy for months. They flowered profusely. They were covered in bugs constantly. The leaves were just drenched with dew. They grew many new rosettes. They looked like pictures I have seen in books and on the web.

    Then after about a month of the hell weather (late August), they started to decline. Almost everything in my collection did at least a little. Example: almost all the D. capensis lost some leaves or the leaves curled up. When it coooled off, they grew again and they look fine. Almost everything else seemed to bounce back too. Not the D. adelae. What is weird is that it keeps growing. It has continued to produce new leaves for two months. They just look really bad.

    Is your area windy? I have 2 pots side by side on the windowsill. The smaller, shorter plant is below the ledge and it is dewy. The larger, taller plant has dry leaves like what you described. I brought the taller plant into the terrarium thinking it was declining. Presto! The dew came back! My humidity is similar to yours so I was surprised that D.adelae disliked having its 'hair messed up'. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile_m_32.gif[/img]

    Another possible reason for D.adelae drying up is that it is dying back. Don't panic 'cos you'll get many plantlets when it regenerates from its roots. [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    It has been windy at times but on the patio they are protected mostly from the wind.

    I think I will put a modified 2 L bottle over them to protect them a little and raise the humidity a bit.

    I have read that some times they just die back and then regrow.See what happens.

    Yeah adelae is a real pain for me as well.
    main thing i learned was KEEP THE TEMPEATURE BELOW 80!!!
    light helps, good watering too, but if its too hot, its screwed and there will be no dew. Only on new leafs.
    Also, the plantlets sprouting from roots are gonna dew up in no time... my tiny babies are already as dewy as parent plant, only about 10 times smaller [img]http://www.**********.com/iB_html/non-cgi/emoticons/new/smile.gif[/img]

    Your conditions seem fine. It may just be "spontaneous" die-back, as Cindy suggested. It happens sometimes.

    Dimka also has a point.....my D.adelae will grow and produce dew when temps are in the mid-80/90s but they seem to do much better when temps are between 65-80F.
