Budding versus own root
Comments (39)Camps. I didn't realize Glenburn was not talking about the States, my mistake. Got confused by the phrase 'imported from Europe' but I should have known better... lol I live in an ex-rural, ex-seaside summer vacation place that is now mostly part of the sprawling Athens suburbia, about 40 km east from the center of Athens, by the sea. Yes, I do grow citrus trees as a hobby, I got about 30 of them in my garden, various kinds and varieties and I also grow some in pots (mainly until I can bud them to some suitable rootstock). Citrus are grown commercially in Southern Greece at low altitudes relatively close to the sea. Northern Greece, mainly stone fruit country as you noticed, is already too cold for them as are places in higher altitudes and places too far inland. Citrus and England don't mix well, I know, unless one wants to grow just rootstocks like trifoliate orange and its F1 hybrids which produce inedible fruit, just for decorative purposes. Even under cold glass growing citrus in England should be very iffy, I think. Nik PS. How on earth can one get stuck in Polykastro, a small rural town north of Salonica on the road to Bulgaria? What on earth had you been doing there? That place is really hot and humid in the summer and can be bitterly cold in the winter.

Comments (36)Nik, I know that Americans farther South than my zone 6a do plant in the Fall but I have had no personal experience with warmer zones. However, from my zone North (and that's a lot of territory), Fall planting is not a viable option. In August it is too hot to plant, getting in the high 80s and then the first frosts come about the first or second week in October. Four to five weeks is not enough time for the roses to get established and prepare for the hard frosts soon to come. Our last frost date is May 15, so that is about 7 months. Usually we have snow cover then it melts, then more snow cover and on and on through the winter. This is especially bad because repeated freezing and thawing cycles heave plants out of the ground. A constant snow cover, which we do not have, would prevent that and in addition would be protective insulation, keeping the plants near 32 F instead of the -10F air temperatures normal for this zone. It may be difficult for most Europeans to sense the degree and duration of cold that we experience, Scandinavian countries and Scotland excepted. When I read English gardening books that say a plant is cold hardy, I have to remember they mean that it will survive in a zone much warmer than mine. Most of England is zone 8! Compare the Hardiness Zone maps on Garden Web of Europe versus The United States. The color of the zones give a more intuitive feel for the difference in climate.

Comments (7)@Erasmus YES! Hortico sends good bareroot plants budded on new seedlings (as rootstock) to prevent the spread of virus. Some varieties are bigger than others, but that’s due to the variety’s vigor. Because of their conscientious and transparent policy against spreading virus, Hortico is my preferred source for roses in general, but especially for David Austin roses. 30% of my roses gotten directly from DA-USA have been virused. They will replace them for you, but don’t actively hold their growers accountable for spreading virus, and so the vicious cycle continues indefinitely. I have a suspicion that some of their mother plants are virused, I don’t think it’s possible to find a clean plant of Constance Spry in North America unless it’s been indexed by UC Davis. Even though shipping is higher from Canada, Hortico’s DA’s are $19 each as opposed to DA-USA’s price of $28. I have no affiliation with Hortico, but support and promote them because I like the way they conduct business, and don’t want them to close permanently like Pickering. They’re a family owned mom & pop shop. On the other hand, I personally feel that David Austin, Inc. is rich enough as it is, and abhor their plant patent politics. They are my last resort if I can’t find it somewhere else....See MoreTips for own root versus grafted roses in pots & LongAgoRoses bands
Comments (100)Thank you, Stephanie, for the tip of Garden Tutor Soil pH Test kit strips. I find that soil pH test via a solution (red-cabbage juice) is more accurate since it takes at least 1/2 hour for the minerals in soil to dissolve in water. I tested soaking coffee ground in red-cabbage juice, at first it was acidic (pinkish), but after 1/2 hour soak, the solution became clear, coffee ground is known as a buffer. Same with rose park nearby, they scattered a layer of gypsum on top of their clay. I scoop up 1 heaping Tablespoon of their soil and tested in red cabbage juice. At first the solution turned pinkish (acidic), from the 18% of sulfur dissolved first. After 1 hour, the solution became very blue (alkaline), from the calcium of gypsum being slowest to dissolve, plus the alkaline minerals in soil was slow to dissolve. SARENA: for the reason above, it's best to mix gypsum 1 month in advance into soil, and let rain or a few waterings release its acidic sulfur to dissolve minerals in soil (rather than to corrode roots). Since you are in a high-rain climate, it's good to have solid minerals on top to buffer acidic rain, such as a thick layer of Worm Casting (pH 7.4), or your clay (if alkaline like mine at pH 7.7). Vermiculite is to improve moisture and to hold nutrients, plus to make potting soil fluffy for wimpy own-roots. Perlite has zero nutrients but good to MIX-IN so roots can have more oxygen for growth. Own-root roses like moist but airy soil. Both vermiculite and perlite is best mixed into potting soil. One rooting method recommended by University of CA at Davis is to mix 1/2 vermiculite (for moisture & cation exchange) plus 1/2 perlite (for aeration)....See MoreMoses, Pittsburgh, W.
