  1. I grow a couple of mexican pings, both in the mix that Adrian Slack describes in his first book, they seem to grow very well in this. I tried laueana in an inorganic mix but it didn't really like it. Once potted into Slack's mix it went bananas and now I have a thriving potful.
  2. Thanks Platty, that looks a bit overkill for my requirements though...
  3. Well, I have recently had a wake up call having been rather relaxed about my greenhouse heating in the past, as 2 out of 3 of the heating elements failed in my fan heater just before Christmas. Luckily the weather has been mild, so the remaining 1kw bar kept the temperature up reasonably until I replaced the elements ( an old Parwin heater, luckily I bought a set of spares before Parwin ceased trading). So now I am thinking of some sort of remote temperature alarm. My greenhouse is too far away from the bedroom (assuming a failure is most likely to occur when I am asleep!) for a Bluetooth de
  4. Hi Karsty I think you probably abandoned the predatory mites a bit early, it takes a while for them to get going! I'm not surprised you had a random occurrence of mites on the other side of the room. Brevipalpus don't spread very fast, but they are very easily transferred on skin and clothing when you handle plants, and of course if you move plants around... The best way to totally eradicate them is probably to completely destroy any plants with mites and then spray the rest of the collection. I have found that plant oil based sprays are very effective. 3 sprays at 2 weekly inte
  5. I would say too much sun. Looks typical of sun scorch in its patchy distribution on an otherwise healthy leaf. It doesn't take much sun to scorch an Alocasia!
  6. I think you will be lucky to find any plant which will out-compete Utricularia bisquamata! Virtually all my pots have a bit of this Utricularia , irrespective of how much moss they have.

  8. Hi Karsty I've had a good look at the one photo I can see on my PC now: they look like brevipalpus to me: I can make out clusters of oval reddish eggs, and the adults look like brevipalpus. The good news is that they spread very slowly from plant to plant so you may find you can control them fairly efficiently.
  9. Hi Karsty if you have brevipalpus you should easily be able to see the oval bright red eggs under a x10 hand lens in good light Sent from my iPhone using Tapatalk
  10. They are annoying beasts, one took half the leaves off a choice pelargonium in my greenhouse this autumn before I noticed. The moths are most pretty though [emoji3] Sent from my iPhone using Tapatalk
  11. For cactus and succulent seed you can’t beat Succseed and Mesa Garden in my opinion, however for the other stuff I have no idea Sent from my iPhone using Tapatalk
  12. I grow my Dionaeas in a 50/50 mix of peat and silver sand , and have done for about 20 years. They grow just fine Sent from my iPhone using Tapatalk
  13. Hi Karsty According to my ‘bible’ of ferns (Ferns by Jones) most adiantums are calcicoles and it does sound like your original compost was acidic. I just use a normal JI type compost for adiantum and they do fine (unless I forget to water them [emoji3]) no need to grow them on chunks of limestone. Sent from my iPhone using Tapatalk
  14. Just been looking at my spore collection in the fridge, I have about 25 different packets, some of which are over 20 years old, I think I will grow them all out next year to see whether they are viable ( I have grown Pityrogramma from 11 year old refrigerated spores a couple of times in the last 20 or so years!)
  15. Well heres a couple of photos taken with my phone camera down the eyepiece of my microscope! As you can see the sporangia are very dark brown and the spores (a few visible almost in the centre of the second picture) are pale straw coloured. Interestingly not very many sporangia with ripe spores, which may be because it is a hybrid (hybrids typically produce lots of small white spores and a few large typical spores, or none at all), or maybe just drought at the time of formation...Like your superbum, mine is now producing the spore patches on the fronds that will give next years spora
  16. Looks like it. They are very pale though, mature spores of most ferns I have looked at have been brown or yellow. However I don’t know what colour veitchii spores should be (I will check my lemoinii later and let you know Sent from my iPhone using Tapatalk
  17. Yes it certainly produces sporangia although I have never tried collecting the spores. Most accounts seem to view it as a veitchii cultivar , if so it should come true from spores. It has a very plastic morphology, you have to grow it in full sun and keep it dry to get the vertical fertile fronds and the frills on the sterile ones. The Tilly is T. myosura, quite easily grown, and tends to seed itself around Sent from my iPhone using Tapatalk
  18. Brilliant! You will have to move house when it grows bigger There used to be a huge plant of superbum growing in the old tropical house at Kew, I remember it well from my first visit there many years ago. I dont know if it lives in the new glasshouses since built, it's a good many years since I visited last. Here is my P Lemoinei (supposedly a cultivar of veitchii, or a hybrid between willinckii and veitchii depending on which account you read. It certainly looks much more like veitchii than anything else:
  19. That’s not likely to come to much, it throws small plantlets about 2 or 3 inches across which establish easily and don’t weigh a lot! Sent from my iPhone using Tapatalk
  20. You can have a bit for free! No worries I’ll let you know next time I decide to chop it up [emoji3] Sent from my iPhone using Tapatalk
  21. Yes I have a low power binocular microscope so I had a look with the x20 lens. It does suggest that, normally when I collect spores I check for ripeness and then put a cut frond on a piece of paper overnight. If the spores are ripe all the sporangia will release the spores onto the paper. If not ripe you get very few or no spores. That superbum sounds spectacular! Platycerium are quite tough and tolerant of low humidity. My Lemoinii is in a too small hanging basket in my unshaded greenhouse and gets very little water all year around, less in winter. It has fronds about 50 cm
  22. Certainly the hybrid Lemoinii, (which has veitchii as one parent ) is happy in dry sunny conditions and tolerates the cold . However the gametophytes will need moisture to grow, but as you say may well need extra sun. I would tend to suspect unripe spores though as inspection of the dried contents of the spore package showed very few free spores, and lots still in the sporangia. That suggests the sporangia have been scraped from the frond surface, rather than allowing the spores to release naturally. Time will tell Sent from my iPhone using Tapatalk
  23. Sadly all things don’t appear to be equal [emoji53] no germination of veitchii thus far. I’ve moved the pot to a cooler better lit spot which may help. I will repeat sow in spring as increasing day length apparently improves germination Sent from my iPhone using Tapatalk

    If they are winter growers it may be that light levels in the U.K. don't get high enough for flowering, it will be very interesting to see how you get on [emoji3] Sent from my iPhone using Tapatalk

    Interesting, I havent tried it. I saw some plants that looked like dormant Xerophtya on the Kelnan plants stand at the Tatton Park flower show this year. I thought Id taken a photo but apparently not
