Comments (5)I have also found that many of these guys have continually produced new and larger petioles. They sometimes make small ones too, but overall they get bigger and bigger, and I haven't seen them exceed 3 at any given so far. Right now, I only have a couple titanums left, not even the largest ones. I have sold off 30 something plants to a couple dozen people, perhaps 40% in southern Florida, and mostly through the south through the summer. The largest reported size I've heard of so far is around 2 1/2ft petioles and 1 inch stems which is pretty decent for 10 month old plants, but most likely only possible because they were strong plants to start with that were sent down south where they get more heat and humidity. The ones I still have are no more than a foot tall and this is to conserve window space as I can't have tons of plants to over-winter. This is the latest one that I sent out around 2ft tall with 3 petioles, and a 4th one forming, likely getting to a decent size based on how it looks now. The corm appears surprisingly small, less than the size of a tennis ball, but larger than a golf ball, but likely because the 3 new petioles were just produced a few weeks ago....See MoreNutritional deficiencies on rose leaves in west coast FL?
Comments (13)In general P is not deficient in most garden soils (again that's talking without knowing your particular situation). In addition roses do not seem to be heavy P users (cereals are). Most gardens could easily flourish without any P addition. P also does not easily leach with rain. Excessive P can affect greatly the availability of other nutrients (mainly iron but others also). All this is just theoretical and greatly depend on your pH also. But this is the general idea. Applying a foliar spray of N and Mg wil probably quickly fix some of your issues (in the space of a few days). If your soil is Mg deficient then you should apply Mg in the soil also. I'm pretty sure you will need to add N too (easily leaches out and is the single most important nutrient in a garden environment and the one most commonly in deficit). But you won't know if the soil is deficient in Mg until you test it. What I'm trying to say is that a plant can be deficient of a nutrient while the nutrient exists in the soil and there are other reasons that can bind it in the soil so the roots cannot uptake it or the roots cannot uptake it because of wrong soil conditions (wrong pH). Professional produce growers get both the soil and the leaves tested to know exactly what's going on. The leaves green up again if they are not beginning to senate....See Moremadri_gw
