Remove seed from berry. store at 70F for 2 months (consider time spent on plant) Then at 40F for 3 months ..... then lightly cover the seed soil temp 60-80F & takes up to 18 months to geminate..... Cuttings wiyld be faster

Pollinating insects are VERY attracted to holly, so I'd wager that your plant has a good chance of being pollinated.

i cant reply to GWeb emails .... if you dont allow emails on your members page ... trees/conifers/shrubs.. in pots.. need fert.. because watering flushes out the good stuff in the media ... i just dont see where any of the named plants NEED anything from you.. but water.. to get over the fact you transplanted them ... are you suggesting.. your county is barren of native plants.. for lack of feeding.. your county soil so sterile.. that nothing you plant will survive without you juicing them??? listen.. i am a cheap SOB... i am leery.. of anything the guy sells, who recommends it ... its nonsense.. that plants are like children..and need to be fed .. that said.. a little of this or that wont hurt anything.. they just dont NEED it ... also.. if planting under aggressive trees.. such as maples.. when you dig a hole.. you sever maple roots.. and they will grow new feeder roots into your plant.. more so.. if you put plant food there.. and if your plant fails.. its usually from the maple sucking the life/water out of the soil ... in other words.. you fed the tree.. not your plant ... transplant are stressed.. from the transplant.. water helps them grow the roots .. to get over it.. feeding them does NOT help them get over it ... do whatever you want... but do it for the right reason ... rather than some gut feeling.. that you need to feed your children.. plants are not children ... ken

Could be 'Nellie Stevens' holly. Hard to tell without a closeup of leaves. But these can be prolific berry producers. And yes, most people want lots of berries! Usually robins strip my hollies of berries in the winter when worms are a scace comodity, but for some reason those of Nellie Stevens aren't quite as much to their liking. If robins can find worms (soil not frozen), they'll usually avoid the hollies. I don't think you can do anything except remove the trees if this really is bothersome. There's a holly called 'Eagleson' (or Eagleston) of comparable size that is gorgeous and makes a lot fewer berries. One other thing you could try is to trim back the hollies just after they are finished blooming. This way, you remove a lot of the spent flowers and developing fruit. We don't normally advocate that, as most people want the berries! I do not know whether these berries will readily sprout and become a 'weed' problem. Some hybrids (if that's what you have) are sterile. My hollies rarely sprout around the yard except for Castle Spire. I do get a lot of native I. opaca sprouting though.
