  1. Spray the plant with an insecticide like BugClear Ultra to kill the aphids. That spray will not harm the plant. Kind regards, Rob
  2. The bags do say suitable for aquarium so it should be good for CPs. Make sure it is silica sand and I should certainly wash it and finish with a rainwater wash before using to be safe. If you have a TDS meter then suggest checking after you have done your final wash. Total Dissolved Solids should be between 10 and 20 ppm after giving it a good wash. TDS meters can be bought cheaply on Amazon if you do not have one (£10 - £15). Rob
  3. Were the seedlings covered by a polythene bag or in some sort of a closed environment? I would suspect the sun may have cooked them - my suggestion would be to keep them in light shade until they establish themselves. All seedlings are fragile and need some sort of protection from full sun for the first few weeks. The compost looks wet in your second photo, not a problem in itself, and if the full sun catches them when they are wet then they are liable to be scorched and die. Rob
  4. With orchids, I had a misting system and water storage containers under the benches to wet all the floor and keep the atmosphere damp. It worked well. I would have thought if you mist the canopies of CPs, there will be a danger of scorch in the midday sun unless you have a lot of shade cloth on and then you are reducing the sunlight they need. Perhaps mist the tops in the evening, but I would be careful during the day. Rob
  5. Looks very good and some really nice plants there. How long do you give it before you fill the place up ? 1 year, 6 months? Or less? Rob
  6. You can buy a TDS Meter (Total Dissolved Solids) from Amazon for less than £10. Do a search on TDS Meter for a selection. Always good to have for testing your water and rainwater should be anything from about 8 - 15 ppm if not contaminated. Water less than 50 ppm is usually fine for carnivorous plants. Kind regards, Rob
  7. Now that one I like . It is good to have some tall growing tuberous Drosera at this time of year Also the regular Drosera above. Kind regards, Rob
  8. Bernado, The original post by cgarry with photos appears to have been made in 2006. The photos must have either been removed or lost from their original location, thus we cannot see them any more. Kind regards, Rob

    Tuberous Drosera

    They are nice, thanks. Kind regards, Rob
  10. If you use pond liner or thick polythene, make sure it comes well up the inside of the planter. Then you have a sealed reservoir many centimetres deep which will be deep enough to hold a large enough quantity of water for the Sarracenias. Alternatively, make sure the planter is always standing in a water tray as you would do for a regular carnivorous plant pot. Kind regards, Rob

    Pygmy Drosera

    How long do these plants normally survive? I grew a range of pygmy drosera for the first time last year from gemmae including D. scorpioides, enodis, gibsonii, macrantha, pulchella, roseana, sargentii, sewelliae, stelliflora and others. Most grew well during the summer and have produced gemmae which I have now replanted. My question relates to the 'adult' plants which produced the gemmae. Will they regrow this year or will they die and just the gemmae grow? I ask this because some of the plants still look very healthy and I feel sure will regrow in the spring - particularly the larger plants like scorpioides. Other plants like roseana seems to have a mix of plants, some of which still look healthy but also has other plants which look dead. Then there are some species especially gibsonii and sewelliae where all the plants look dead to me ie they are brown and look lifeless although they did produce a few gemmae. So should I expect last years pygmy drosera plants to regrow or only expect the saved gemmae to grow this year? Thanks, Rob
  12. So Guy, it would seem that if you want to continue using your Inkbird thermostat for more precise temperature control, you need a separate ordinary fan - or another fan/heater like you have already but plugged directly into the mains and set to fan only - to keep the air moving. Kind regards, Rob
  13. Hi Guy Maybe you have a slightly different model but the Amazon description from Dunc's link does state "Features continual fan operation to aid greenhouse airing, frost prevention and extending the life of the heating element." Also, in answer to a question about the fan/heater, an Amazon user states "The fan stays on all the time but, the heating element turn off & on and keeps a stable temp." So maybe you have a slightly different or older model as Dunc states they are sold under a number of different names. Kind regards, Rob
  14. Hi Edmund Leave the still green pitchers on the Sarracenias and the VFTs as long as you can but cut off anything that is brown or black. The green pitchers or phyllodia are still providing nourishment to the plant as a whole. If you cut these off you are depriving the plant of some nourishment and it may then be smaller next year. Here is a recent short youtube video from Matt Soper of Hampshire Carnivorous Plants showing how and why to trim your plants: Cutting Back Sarracenia for Winter. Kind regards, Rob
