Last June I planted in ground in a very sunny spot a Brown Turkey and what I believe to be a Lattarula (I got two of these from Paradise Nursery as "Mystery Figs" before they closed shop. They matched the description of Lattarula when they fruited for me, though I recall Herman suggesting those trees were Italian Golden Honey or something to that effect in a thread last year. I digress. I'll try to anticipate as many questions as possible, so my explanation/question may get lengthy.
The trees were likely in their fourth leaf when I planted them in soil that is likely low fertility with good drainage. I top dressed them with a couple of inches of compost at planting and again at leaf drop just before I covered them. They handled winter after being covered with the burlap/tar paper/ leaf method with a little tip dieback and have absolutely flourished this year grown as bushes. The BT is probably 3'x3' and the Lattarula slightly smaller. The BT was late producing main crop figs, putting them out beginning a month ago and still doing so now. There are many. The Lattarula has no fruit as I type this. Interestingly, the sister plant, which I kept potted and root pruned hard in late winter also has no fruit though the remainder of my older potted trees, several of which I also root pruned hard, have fruited, though I think at a later date than in the past couple of years.
The area I live in, Reno, NV, is listed Z5/6, depending on your microclimate) had an unusually cool and wet three week stretch in June that must certainly have affected growth of the trees. Other than that, it's been hot as blazes and dry as a bone for most of the summer to this date - normal for Reno. I have not fertilized the in ground trees at all other than the compost addition described above and water them deeply every week or two. Both trees have produced every year I've had them. Though I usually have had brebas in addition to main crop figs, I had no brebas this season, which I attributed to their first winter outdoors. I also, following the Herman Method, pinched out growth of many - not all, but I did pinch all of the fastest growers - of the branches four to six weeks ago, though mostly on the BT, since it grew faster than the Lattarula.
Perhaps the vegetative growth is too rank and that has affected fig production. I will post a couple of pictures tomorrow or Wednesday if I remember to take them, so others can offer critiques/advice after visual inspection. I suppose it could all be due to the weird stretch of cool late spring weather, but that didn't seem to slow their growth much outside of possibly delaying actual fig production. What say you of greater experience?
