Frost around flowering time? Did you have flowers? Bad pollination? Maybe since the trees are so young and you got fruit so early, you taxed the tree and now its just saving energy for next time.

In my brief experience I wouldn't say hardy kiwis are as tender as tomatoes. We had back-to-back freezes mid-April this year that hit a lot of things hard: all the new foliage on the mulberries, 99.9% of my Asian pear crop (but not the pear leave), the native persimmons that had leafed out already, all the early strawberry bloom, all the growth on a gingko tree (something I hadn't seen before in my 7 years here)... In other words, we had a fairly severe late spring cold event, and there was a lot of new growth on my kiwis that was zapped, but randomly throughout my one largest vine (Anna) there was quite a bit of growth that survived, and I have an Issai in a sheltered spot -- it's the only variety that's bloomed for me so far, but all my other vines have only been in the ground for about a year -- that's still blooming now. For whatever it's worth, I was first introduced to kiwis from a local vine (completely neglected, growing in an apple tree) in 2011, and I discovered another vine just to the east where I was able to get some fruit last year, so they seem to fruit in this area often enough. The vine I got fruit from last year hadn't been pruned in at least a couple years and was loaded with fruit. It was pruned heavily this winter. I'll have to ask if there's fruit on it this year. I think it's just far enough to the east that it escaped the late freeze this year.

Alright I had to get in on this. I live in North Houston, Kingwood area with a 9a climate, grow mangos, tamarinds, kumquats, N33E oranges, purple and banana passionfruits, key limes, calomandins, jackfruit, dragon fruit, and various others but those are my most proud plants. Let me start with this, in this area I can go and take pictures tomorrow of lemon trees growing wild in Kingwood and New Caney, then in Crosby I know of a blood orange growing wild in the woods. If you update your information you'll quickly find out that meyers lemons, Persian and Mexican limes, kumquats,calmansi/calomandin, and sour oranges are the most cold hardy. Don't water any tropical fruit plant during winter if you're in a 9a and above, even 9b is kinda skeptical. Wait until temperatures don't dip below 60 to water them. The hotter it gets, the more you water, BUT DON'T FLOOD. I do not even use fertilizers, i simply prepare a good humus, compost, sandy, and peat moss soil... All natural for my babies, haha. After 2 years take the top 6 inches off and replace it. As you water, these nutrients will reach the bottom. My key lime fruited in its' first year. During winter take them in if you're in a 9b and above. Now for the burn comment, no. We're talking about tropicals here, as long as you keep the soil moist, not soggy, you'll keep a "tropical" climate for the roots and not a desert one. Trust me, I know all too well about our "sonic cup melting" summers haha. Another thing, as long as your plant has thick leaves usually, not always, the general rule of thumb is it can handle a sun burn. Good luck to y'all and good planting.

I only "watched"... not listened ...to his show ONCE on late night TV... I have no idea why, but the TV version was just a live recording of his radio show...sorta like they used to do with Don Imus in the morning. SMUT is the correct term. PORN would also work. Not even gonna tune in. Tired of nothing on TV being able to be watched as a family.
