Help! Tomato & Pepper leaves are yellowing/browning!
Comments (5)I would think the plants should have taken hold in three weeks. Assuming you see no insect pests and the plants are getting sufficient water, I guess it could be draining too fast and taking nutirents with it. I have seen that happen with really sandy soil but why aren't the beans and cukes affected. Maybe the problem is that my experience is with the dirt that came with my house and I know squat about licorice root. You might try to get some nitrogen to the plants with the recipe you mentioned or some water soluable Miracle Grow....See MoreHelp Please Clematis w. Yellow Leaves
Comments (2)thanks for your answer! Although it has been quite hot here for a while, and I doubt very much that it received too much water, rather not enough water... No fertilizer for now? Hmmm, well, last night I felt so sorry for the plant, I already gave it one good drink of epsom salts water, and put some mulch on its feet, since I realized that the ground covers that used to grow there did not come back this year....See MoreSmall Hoya leaves slowly turning yellow
Comments (11)I used to believe that it took carnosa that long to bloom, but after Pepeuve's posts, I'm now a believer that in ideal conditions, carnosa can and will bloom quite quickly. You can see in the link below a cutting he took of a carnosa that formed 5 peduncles in under a year. I'm not sure how much longer it will take the cutting to bloom, but it's certainly doubtful it will need a decade. If you ask his advice, he says: sun, sun, and more sun. And if you go to his blog, you can see from his photos that his Hoyas, grown on a balcony in Malaga, Spain, have very very pale leaves. My carnosa is over 10 years old, however I grew it in dim light for most of that decade, because I didn't know any better. After I put it right up the glass in an eastern exposure, it formed peduncles within a year. I find it hard to believe that after 2-3 weeks in summer, your plant hasn't had sufficient time to dry out. (In fact, that sounds closer to a case of underwatering and underfertilizing). It is a good sign that you are seeing healthy roots at the bottom. If you're still seeing a decline, this is what I'd do. First, take it out of the pot and look at its roots. They should all look creamy/tan and firm. You want to be confirming that none of them look brown/black and shriveled. You also want to keep your eyes out for fungus or insects. If they look okay, then repot it with some extra perlite and/or bark like Kukka suggests, and try and step up the watering schedule a bit. The next time you're ready to water, stick a chopstick or kabob stake all the way to the bottom of the soil. This is just to confirm that the bottom of the pot isn't somehow staying damp through some miracle. It is a little weird that this pot is draining more slowly than the big one. Normally I wouldn't go through this rigamarole, but it's clear something is wrong and we have to start eliminating possibilities.

Comments (11)Also, to confirm...are you using soil? Calycina prefers a nice airy mix. I use 1/4 inch Orchiata bark, #3 perlite, and 1/4 inch LECA (expanded clay) balls, all equal ratios. In a pinch, a high quality fine grade orchid mix (no soil) from your local garden center will do. Soak ingredients overnight and rinse well. Rinse off as much of the old potting soil as you can from the root ball. While you are able to see the root ball and root stem, check for signs of rot (stringy, squishy, stinky, discolored/mottled roots, squishy, stinky, black or brown root stem). If all looks okay, pot up in the new mix. You may need to water more frequently, until the orchid mix has had time to "saturate" and hold water more readily. The overnight soaking prior to using helps a bit, but the mix still may dry out rather quickly until it adjusts....See MoreRelated Professionals
