"We do some straw, and it's been very difficult to find a window of opportunity for that type of thing," Harman said. "With other vegetables, when you have this rain and this much dampness and the heat, it does lend itself to diseases."
Harman said she has to take more preventive measures to protect the crops.
"Tomatoes aren't happy with this much rain. They do like to dry down a little bit and they have not had an opportunity to do that."
"It's not just the quantity of rain, it's just that it's always wet. It's heavy dews in the morning constantly," she continued.
Darin Van Houten, of Van Houten Gardens, said it has also been tougher to get customers to come out. His business, on Route 22 across from Harford Community College, has plants, flowers and gardening supplies, as well as some produce.
Tuesday morning, it all stayed wet as rain fell on and off until close to noon.
"It's definitely been more rain than we would like," Van Houten said. "It makes it harder to take care of the plants."
He said the extra moisture contributes to root rot in the plants, which forces him to check every single pot before it's set out. He also tries to set more things in the greenhouse.
"We try to be as vigilant as we can," Van Houten said. "It makes watering more time-consuming."
Van Houten's 200-acre farm in central Pennsylvania has been much drier, which has helped keep produce from the ill effects of the rainfall in Maryland.
He said he has minimized the business' losses by making sure plants get spaced appropriately, for one thing.
"When they're wet all the time, they can't be touching all the time," he said.
Although Van Houten also said it was too early for produce to really be affected, he expects more insects in the coming months because of the wetness.
"It's going to be a lot of bugs this summer. Japanese beetles have come out in force," he said.
Other gardeners thought the rain has been just right.
Stan Kollar, of Kollar Nursery in Pylesville, said the water has been a welcome relief from the dryness of previous seasons.
"It's usually really hot and dry," he said, noting the rain "has helped things grow very nicely."
Kollar did think the moisture has created some problems in terms of more fungus and he said the "intense storms have wreaked havoc" on slopes in Harford County in general.
Fungus and mildew have not, however, affected his nursery much.
Kollar thought the corn he saw around the area is taller than ever.
"I think most farmers are probably delighted with the rain," he said. "It's not been inordinate."
