Potted Cityline Paris Hydrangea
Comments (1)How large a container needs to be, or CAN be, and how much soil a planting needs/will tolerate before drainage & saturation is an issue depends on the 3-way relationship between plant mass, container size, and soil type. We often concern ourselves with "over-potting" (using a container that is too large), but "over-potting" is a term that arises from a lack of basic knowledge about the 3-way relationship noted, which should logically determine appropriate container size(s). It's often parroted that you should only move up one size in containers when "potting-up". The reasoning is the soil will remain wet too long and cause root rot issues, but it is the size/mass of the material and soil type/composition that determines both the upper & lower limits of appropriate container size - not consecutive volume progression. Plants grown in slow soils need to be grown in containers with smaller soil volumes so that the plant can use water quickly, allowing air to return to the soil. This (smaller soil volumes) and the root constriction that accompanies it will cause plants to extend and gain o/a mass much more slowly - a bane if rapid growth is the goal - a boon if growth restriction and a compact plant are what you have you sights set on. Conversely, rampant growth can be had by growing in very large containers and in very fast soils where frequent watering and fertilizing is required - so it's not that plants rebel at being potted into very large containers or volumes of soil per se, but rather, they rebel at being potted into very large containers with a large volume of soil that is too slow and water-retentive. We know that there is an inverse relationship between soil particle size and the height of the PWT in containers. As particle size increases, the height of the PWT decreases, until at about a particle size of just under 1/8 inch, soils will no longer hold perched water. If there is no perched water, the soil is ALWAYS well aerated, even when the soil is at container capacity (saturated). So, if you aim for a soil composed primarily of particles >1/16", there is no upper limit to container size. The lower size limit will be determined by the soil volume's ability to furnish water enough to sustain the plant between irrigations." You can grow a very small plant in a very large container if the soil holds little or no perched water (saturated soil).

Comments (4)Well, I'm in 6b and what I said is based on my 4 years experience with all four of the Cityline. First obtained them in 2006 as a rooted cuttings in 4" pots. Replanted in 2G and overwintered all 4 in a coldframe. Spring 2007. Planted Berlin+Venice in ground and replanted Paris+Vienna in 3G. Took cuttings from Paris. Spring 2008 (after warm winter). Venice didn't make it at all (roots were alive, but all 5 canes died). Berlin's canes survived, but all buds were dead. Replanted Paris in 5G and planted last year's propagated plant in ground. Vienna still is in 3G. Spring 2009 (after long and cold winter). Berlin died almost to the ground. Paris (in ground) died to the ground, though plant was young to begin with and winter was too harsh. Both potted plants (Paris+Vienna) overwintered perfectly and blooming right now. IMO, of all four, only Paris and Vienna worth the trouble with overwintering. Neither Berlin nor Venice show anything distinct, just a regular pink mopheads. Paris is a compact 2-2.5' shrub with very bright raspberry red flowers and Vienna is a true dwarf (1.5x1.5') with pinkish-red (though not as bright as Paris) proportionaly smaller flowers. FWIW.

Comments (2)I had a couple of cityline venice, paris two yrs back..from my experience, these guys are very compact with fairly short internodes between the branches...i wouldn't bother to pinch it because the plant is tight and compact already..they tend to grow slower than the common Endless Summer,.one thing about the citiline series is - small size is great, little pruning if ever is needed...but blooms on old wood..and some of my clients' cityline plants didn't make thru this winter - it's a truly wild and crazy winter here in Jersey...because you are in zone 5 - you really need to protect the plants during winter if you want blooms next yr..jmho..btw - venice looks GREAT in deep purple (the color of this series is very vivid and intense..Paris should be in the red form..)...See MoreCityline Paris Hydrangea
Comments (1)I would not intentionally plant a bigleaf hydrangea in full sun in any zone. Regardless of what the plant tags may say, these are essentially woodland plants and need a part or dappled shade environment. Morning sun & afternoon shade is fine. Even in my very mild and far northerly zone 8 location - where the sun is not very intense and it never gets too hot - bigleaf hydrangeas in full sun wilt on a daily basis....See Moreego45
