Fertilizer for potted rose babies
Comments (7)Thanks Kaye! Guess I am always in a hurry, but I want them to grow off fast so they can be ready for winter. I want some early basal breaks. I have some good looking activity on the cuttings you gave me. You were right about Lamarne...sure hope it has some roots to go with all the new growth. The Chinas are being slow, though. I only see one leaf that looks like it may be going, so far. What is the right name for the "Mexican Hydrangia"? I wanted to look it up, but no luck without the correct name. Had to pamper them a bit...carrying them home bare root, wrapped in wet newspaper set them back quite a bit, but they are getting to where they can tolerate more sun without wilting, now....See MoreFertilizing roses in pots
Comments (5)I alternate between stuff like fish fertilizer and compost teas and stuff like MG and MG bloom boosters etc. I have tons of brugmansia which are very heavy feeders and will eat up anything I can throw at them. I do not mix up separate batches so whatever I am feeding them, I just do the same for all the other stuff too. I have potted roses that get quite a bit of fertilizer and I have not had any problems. I use plastic pots not clay and they get watered several times between fertilizer applications. Also, make sure to never fertilize a dry pot. Always water about a half hour before you fertilize. I killed a rose many years ago by putting fertilizer on a very dry rose lol. Completely fried it!! Never forgot that lesson. ~sjn...See MoreFertilizer plans for pots vs.. in-ground, rain & tap, own-root & graft
Comments (16)High nitrogen can hurt root and flowering ability in cotoneaster plant. See excerpt from below link: http://www.sciencedirect.com/science/article/pii/0304423881900649 " Although root growth was not increased by either Nitrogen or Phosphorus, high N levels inhibited root growth." More link to show that too much phosphorus can hurt root & flowering: https://laidbackgardener.wordpress.com/2016/05/18/the-myth-of-starter-fertilizers/ "further studies showed that large quantities of phosphorous were not necessary for rooting. Yes, the soil must contain a small amount of phosphorus in order to stimulate rooting… but that’s also true of any other nutrient. If the soil totally lacks nitrogen, zinc or iron, that too will hamper rooting. In fact, plants actually root poorly in soils excessively rich in phosphorous. You’re far more likely to kill plant roots with 10-52-10 fertilizer than to stimulate their growth. " http://davesgarden.com/guides/articles/view/3788/ " When plants are grown in low phosphorus environments they emit organic acids from their root tips. These acids allow mycorrhizal fungi to penetrate the roots and form the networks that assist roots in absorbing water and nutrients. If the phosphorus levels are too high the roots do not emit the acid and the mycorrhizal networks do not form. This forces the plant to put more effort into root growth to compensate for the lack of mycorrhizae." U. of Colorado Extension has excellent info. on Organic fertilizers: "recent CSU research has shown that phosphorus from bone meal at NPK 3-15-0 is only available to plants in soils that have a pH below 7.0." On rock phosphate: Recent CSU research results concluded that no rock P (regardless of mesh size) is available for plant use unless the soil pH is below 7.0. http://www.ext.colostate.edu/mg/gardennotes/234.html According to CSU, Kelp powder has NPK of 1-0-4, decent potassium, plus trace elements, only need 1/4 to 1/2 teaspoon per gallon, due to its high salt. **** From Straw: I tested bone-meal many times, with negative result in my soil pH near 8. 1) killed over a dozen geraniums by topping with bone-meal in hot summer .. that burnt their roots, but their colors were vivid at first. 2) put bone-meal in the planting hole of Sharifa Asma, the color DID NOT deepen, but really wimpy root, plus the soil got hardened. 3) Killed a $30 gallica rose gifted by a friend with bone-meal in the planting hole. 4) Made Crimson glory really wimpy by putting bone meal in the planting hole. 5) Made wimpy Yves-pink-seedling into a Black-spot fest by moving it, then put bone-meal in the planting hole. CONCLUSION: phosphorus is best in small amount as in 1/10 of potassium in rose-tissue analysis done by U. of CA at Davis. Phosphorus is best AS soluble, as in leaves, manure. Chicken manure at NPK 5-3-2 has plenty of phosphorus, plus trace elements zinc, copper, and boron....See MoreYour plans for roses in ground and pots: soil prep & fertilizing?
Comments (105)anna, lavenderlace, aztcqn: There is something weird with this site due to which the posts do not show up in time. Most weird thing is that if I make a post from a new device (a new loptop, mobile phone etc), it is not visible even to me when I login from a different device. I can only see my own posts, immediately after posting, if I log on from the same machine..... I haven't understood how this happens. Feeding during monsoon has been a problem for me since past few years and I have tried different models. Since I wanted to be 100% organic, most solutions that I tried didn't work that well and my roses would stand exhausted and depleted by the end of monsoon. This year, I fed them after the monsoon in August and September with a doze that comprised 1 tea spoon each of Potash, gypsum, a water soluble 36-0-12 nitrogen fertilizer and a trace element supplement that contained Fe, Zn, Cu, Mn, Co and Mb mixed in 18 liters of water (capacity of the bucket). This had a good effect on the roses in pots that you can see in my threads of that time. There is also lot of discussion about the pros and cons of various methods...
