I have found SH2's to be very susceptible to cross pollination from all types of corn. Triple Sweets (Synergistics)seem to co-exist fine with Se's and Su's.

Thanks for replying.

Do I have to worry more about Honey Select pollinating the white sh2, or the sh2 pollinating the Honey Select?

With only 8 days maturity difference, can I successfully grow the 2 if I stagger planting 1 week?

What if I grow the sh2 west (upwind) of the Honey Select?

Or should I just try to grow 1 or the other and not both, or 2 Triplesweets? I also have Avalon & Serendipity.

Honey Select and How Sweet It Is are my 2 favorites, but I got behind here and didn't get the 2nd bed freed up til now. Actually, I already planted Honey Select in the 1st bed around Memorial Weekend but a helper "weeded" the bed by mistake, so I just retilled it. The 2nd bed I waited for the strawberries to ripen and then pulled the plants and amended the bed all in a day (yesterday.) The first bed to the west, I ammended and cut plugs already and filled the plugs with ProMix, I find seeds sprout sooner and more reliably, plus spacing is already laid out. I didn't cut plugs yet in the 2nd bed yet until I decide which variety will go in it--H.S.I.I. does better a little further apart than Honey Select which has smaller flags...otherwise both beds are ready...

I don't know how the corn will do this late--it won't be harvested until early-mid September, when it will start cooling down.

Any suggestions?

It should not affect the Honey Select, But I think I would plant the Avalon rather than the "How Sweet it is"

Thanks for your replies farmerdilla...

The Avalon seed is actually 2 years old and found it in a dresser drawer. The H.S.I.I. seed I just received a couple weeks ago.

Do you (or any others reading this) still feel to go with the Avalon instead of How Sweet It Is? My Honey Select is about 2" tall, planted I think 6/15 or 6/16. It's about a week since planting.

What's less risky--planting 2 year old white triplesweet/synergistic seed found in a drawer at room temp (70-80 degrees), or planting a white sh2/supersweet with an 8 day maturity date difference (plus the week that has gone by) upwind of a yellow triplesweet/synergistic?

Color crossing isn't important to me but I don't want everything turning into field corn... even though I always see Honey Select advertised as "needs no isolation" (why not?)

Any/all replies appreciated. Thanks.

Anybody?

As far as I know, and I grow right much corn, only SH2's are affected to the point that the corn is almost inedible and therfore require isolation. Of course it is alos true of popcorn, popping quality is lessened. By this time you should have enough time isolation to plant the Hwo Sweet it is. You may have germination problems with two year old Avalon. You should test older seed by planting a few in a cup or a damp paper towel before planting season. Just for information I have grown both Avalon and How Sweet it is and strongly prefer Avalon.

Thanks dilla. It looks like it'll be a coin toss. I grew Avalon & H.S.I.I. in the same year (timed isolation) before and like both... The Avalon had much smaller flags and took less space... the HSII had bigger blunt ears and filled right around the ends and some had 2 ears/plant... but they needed more space with big flags, and I only have a 4x7 bed left now and trying to get about 7 rows of 6. If the SH2 is the one to worry about, I don't think I'd have to worry with it upwind and 16 days difference, but spacing may be too close--can I get away with approx 8" spacing, rows about 1 foot apart with HSII?

One of the 2 has to get planted by tonight. Spacing favors Avalon, seed age favors HSII. Since I plant 2seeds/hole, what are my chances with 2 yr old Avalon? And do you bother thinning to 1 when double-seeded?

Somebody please flip a coin...

Avalon won... I hand selected the seeds & triple-seeded them just in case, 3 seeds an inch apart in a triangular pattern per hole; will thin if necessary.

WOW, TEN YEARS LATER! The same dilemma! But the Avalon from a purchase 4-5 years ago (!) had zero germination, so now it is Honey Select & How Sweet It Is, both just purchased though no way of knowing the age of the HSII---I heard it may be discontinued. With DTM about 8 days apart, what's the minimum DTM separation days between a Triplesweet & Supersweet? I've seen #s all over the place! Thanks for any help.
