Growing greatness

Corn that got off to a good start like this earlier in the year is absolutely growing like crazy with the rain and hot temperatures, according to Douglas County Agent Bill Wood. Lawns and gardens are also responding to the conditions.

With the continued mixture of heat and rain, conditions have been good for the growing season. Douglas County Extension Agents Bill Wood (crops) and Jennifer Smith (horticulture) shared their thoughts on the season.

Q. This summer’s heat and rain seem to be helping growth with many plants more than last year’s cool and wet summer. Is that true?

A. “The heat is definitely better than the cool weather for many of our common landscape and garden plants,” said Smith. “As temperatures increase — to a point, of course — so do many of the internal processes in a plant. So, photosynthetic rates increase and result in more plant growth. The amount of increase is exponential, too.”

Q. For the past month, the corn and soybeans have just exploded out of the ground. Is the heat the reason for that?

A. “Corn loves the heat,” said Wood. “You could almost measure it and watch it grow. But pollination is helped by cool. Soybeans pretty much like the heat, too. But I think once it’s growing, corn likes the heat more.”

Q. Are there any harmful effects to the plants from the heat?

A. “The fine line is that some plants, like tomatoes, will only bloom and set fruit at certain temperatures,” said Smith. “Also many fungi that cause diseases also grow better with lots of heat and moisture. My lawn is growing like crazy and it is full of a fungus disease called brown patch.”

Q. Has the growing season got farmers thinking about a bumper crop this year?

A. “We’ve got a lot of variety,” said Wood. “We’ve got some corn and soybeans that got in at the right time that are looking good. Then there are some farmers who had to replant and had flooding whose fields aren’t looking good. In my crop report I said we had 10 percent rated poor, 30-40 percent fair, 30 percent good and 15-20 percent excellent.”

Q. What key times are left for crops?

A. “We’d rather have rain than drought,” said Wood. “We’ve had rain the last two years. The corn will probably be fine, no matter what. August is when we like to have rain for the soybeans. August is key for them.”
