  2. 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.
  3. 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
  4. Caterpillar!

    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
  5. Life after Southwest Seeds?

    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
  6. Sphangnum peat vs sphagnum moss

    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
  7. Adiantum peruvianum problems

    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
  8. Platycerium from spores

    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!)
  9. Platycerium from spores

    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 sporangia.
  10. Platycerium from spores

    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
  11. Platycerium from spores

    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
  12. Platycerium from spores

    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:
  13. Platycerium from spores

    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
  14. Platycerium from spores

    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
  15. Platycerium from spores

    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 long and is clumping up vigorously, every few years I chuck the whole thing away save one offshoot and start again...
