What happens when there is too much rain?
DN: When there is more rain than the soil can absorb, water will quickly run-off into rivers and creeks to overwhelm culverts and storm drains and cause a flash flood. This depends on several factors including rainfall rate, soil type, terrain and amount of moisture in the soil.
What happens to plants when it rains?
The rain doesn't seem to bother them at all. While the cole crops like broccoli, cabbage and kale seem to be thriving in the cool dampness other plants are suffering, the cucurbits especially. So we got a bit of rain, what's the worst that can happen? Disease. Bacterial and fungal diseases thrive in wet weather.

How much rain is considered extreme?
David Novak (DN): While there is no single definition of extreme rainfall, per se, a good benchmark is a month’s worth of rain for a given location falling in one day — that’s a big event. And impacts vary by location.

How to minimize the negative effects of excess rainfall?
Here are some pointers on how to minimize negative effects and outcomes of excess rainfall. 1. Maintain Transplant Condition . Slow transplant growth by lowering fertility, supplemental light, and, if possible, temperature levels (especially temperature levels during daylight hours).
What are the causes of crop nutrient deficiency?
Fertilizer leaching and runoff, leading to crop nutrient deficiency. 7. Waterlogged (and, possibly, compacted) soil, leading to shallow-rooted, low-vigor crops, that may be less resistant to other types of stress. 8. Disrupted planting and expected harvest schedules, leading to supply shortages and excesses.
How does heavy rainfall affect soil?
Heavy rainfall compacts bare soil and promotes erosion and runoff. In the future, consider that both can be minimized by using plant residue mulches or other minimum tillage practices. Root channels and above-ground debris permit rapid infiltration, shield the soil from the impact of rain drops, and absorb moisture.
Does rain kill aphids?
Heavy rains may sometimes eliminate pests such as aphids, mites, thrips, and small exposed caterpillars such as young European corn borer larvae. Damp weather is conducive to diseases such as Beauveria that can infect and kill insect pests. Scout potatoes carefully for late blight, beginning at emergence.
Is it important to use every rain free minute?
Using every rain-free minute most effectively is important. Balance short- and long-term objectives when deciding to work or not with wet fine-textured soil . Working wet, fine-textured soil this year may be useful now, but it will have significant, long-term, negative consequences that are difficult to reverse.
Can you cultivate herbicides in rain?
Cultivate When Possible And Watch For Herbicide Inactivation. Rainfall has mixed effects on herbicides; it may activate them further and/or leach them. Either way, cultivation and post-emergent herbicides may be needed later in the season to compensate for the lack of longer-term action.
What to do if you fear some of your treasured plants might not survive the deluge?

How to fix plants that get washed out of the soil?
Side-dress your plants with a granular organic fertilizer to replace nutrients that get washed out of the soil. This is especially a problem with container grown plants.
Is the West in drought?
While 93% of the West is in some level of drought, other regions are being inundated with rain. After a hot dry June in my neck of the woods, we got 3 times our monthly rainfall in the first 2 weeks of July and another 3 inches just yesterday! What’s a wet gardener to do? See 7 tips to manage your garden after too much rain.
Can you get fungal disease from wet weather?
Disease. Bacterial and fungal diseases thrive in wet weather. The leaves on our cukes, squashes, and melons are showing signs of fungal disease. Even powdery mildew, which usually thrives in dry weather, is on the attack. I’d like to remove as many of the damaged leaves as possible but you really should avoid working with your plants while they are wet. That means delaying weeding and harvesting too. We are just starting to get some green beans but I hate to pick them while the leaves are wet because it spreads disease.
