Comments (6)John, LOL. I am the conservative one. At least I wait until just after the last frost date. My best gardening friend who lives just a short distance from me often plants his corn a week before the last frost date, or sometimes in a warm spring, two weeks before. The soil temperature is what determines if and how quickly the corn seed will sprout. With standard sweet corn (NOT the pickier supersweets) I plant after the soil temperature at planting depth is at or above 50 degrees for at least 3 consecutive days. With the extra-sweet varieties, I wait for 60-70 degree soil. Our late-winter and spring weather is very erratic here with wild temperature swings all over the place. We occasionally have a very warm winter or early spring day in the 80s or 90s even while we're still having freezing nights. If the soil temperature is in the right range, and there's not a big cold front out there in the 7-10 day forecast models, I can plant easily in March for old-fashioned regular sweet corn, and in April for the newer supersweet hybrids. I've lost sweet corn to a late freeze only twice since moving here in 1999, and that was before I started using Agribon floating row cover to keep plants warm on an occasional cold night, so I feel like the risk of losing it is relatively small. In both of those years the corn froze, we had an abnormally late freeze/frost in the first week of May in an area where our average last frost date is near the end of March. Planting early is a risk I'll gladly take because often we get so hot so early that I'll have pollination issues with corn planted "late'. The last two summers we've had that kind of heat arrive in May instead of in July, so planting early to beat the heat has become more important to me than ever before. How much water your sweet corn needs varies a huge amount depending on your soil and how well it holds moisture. Most of my soil is heavy clay (though well-amended with compost in the garden beds) so it holds water a long time. This past summer I grew some in a sandier area and had a really hard time getting it enough water. Of course, we were in the midst of horrendous drought so in that sense, it wasn't a fair test of how well corn would grow in that area in a more normal year. In the drought, the corn planted the earliest performed the best and the corn planted later produced very few ears. There are times when good moisture is extremely important. The most important time is when the plants are young and small. During the first three weeks or so after the corn plants emerge, it is important that they have good soil moisture to enable them to establish good, strong root systems. The other critical period is the time between the appearance of the tassels and the time you harvest. Once the corn is tasseling, it is critical that it receive adequate moisture so that the ears will be well-filled with nice, filled-out kernels. If the plants are too dry at and after tasseling you can have poorly filled, small ears. In between those two periods, corn is pretty tough and can handle less moisture. t lot of this discussion of moisture is relative to what is normal for your area. I live in an area where our average rainfall is about 38-39" a year, with much of that falling in late winter through late spring, and not much of it falling in summer. However, we've had years with less than 18" of rain and years with about 54" of rain. That's another reason early planting is helpful here---it lets you take advantage of this area's rainfall pattern. The last two years we've had about 27" of rain per year, so I've had to water more than usual. If you are in an area that averages 15" ir 20" of rain a year, you'd have to water a lot more in an average year than I do, although if you had good sandy soil that lets great root systems develop, you might not have to water as much as I do if you sand is a sandy loam that holds moisture well. With corn, just try to keep it pretty moist during those two critical periods, and then try to keep it more or less moist, but not sopping wet, the rest of the time. I have a lot more trouble with my corn in a wet year like 2004 or 2007 than in an average year. There is no set formula for watering anything. There are too many variables, including how well your soil does or does not hold moisture, how dry or humid your air is, how windy the weather is, etc. You just have to watch the plants and water when they look too dry. Remember, too, that is is always best to water so that the soil is moist 6-8" down. One mistake new gardeners often make is they water briefly---only enough to wet the soil an inch or two beneath the surface--and they water very often. When a person waters shallowly and often, it encourages the plants to form shallow root systems near the soil surface, and these shallow root systems do demand almost daily watering. Plants that have good deep soil moisture send their roots down deeply to reach that moisture and, consequently, they are happy with less frequent irrigation or rainfall. It is much better to water deeply less often so you'll have deeper, healthier root systems on your plants. In a dry year, I try to water my corn once a week to a depth of 6-8" and I use drip irrigation to do so, which keeps the moisture off the foliage. In a wet or even average year, I hardly water the corn at all. Dawn...See MoreCorn in the Florida Keys
Comments (6)Ill keep going out at night and checking.. I had a problem with army worms on my pepper plants. I rectified that situation by going out every night and picking them off until there weren't any more left.

Im not sure if its good or not but its all I had....See MoreWhere can I find corn seeds like we planted in the 1960's?
Comments (13)That is just because I am an antique Dave. The 50's were my teenage years on the farm. Folks who preferred white corn had no hybrid choice until Silver Queen was introduced in 1960. White corn dominated the Sweet corn market until the introduction of Burpee's Golden Bantam in the early 20's. Yellows took off as there many efforts to improve on the original including some hybrids introduced in the 30's. The old op's ( 19th century varieties) were popular until Silver Queen started a new era. They are antique old commercial varieties Stowell's Evergreen, Country Gentleman/Shoepeg, Black Mexican ( my mother's favorite), Howling Mob. Robson Farms introduced a long line of Seneca series sweet corn starting in the 30's and they were good but all yellows...See More- 13 years ago
