“Rain, rain, go away, come again some other day.” We used to sing that song as kids. After starting the spring and summer with some of the driest weather we have had for some time, we are now inundated with rain. The only advantage to this is that seed starting was easier, but only because the soil was heated up a lot by the time this rain hit. Otherwise, all the seed would have rotted. Unfortunately, we seem to be getting more rain than we bargained for…

A good soil will hold moisture and therefore help the plants survive between rain spells. In our garden, we water long before the plants would suffer. When it rains as much as it has, the soil can become waterlogged, leaving no space for air. This is a horrible condition for our plants to grow in. Unfortunately, there is not much we can do about it now. Raised beds help excess water drain away from our plants, but those would have had to be installed before planting in the spring. There really is no way to cover the plants to prevent the rain from hitting them as the water table is so high it would not matter (not to mention the plastic and humidity would make matters worse).

Mold, mildew, and fungus thrive in this kind of environment. Don’t be surprised if your cucumbers, squash, and phlox become covered in it this year. There are sprays that help, but I generally do not do anything and hope for more sunlight. Soil borne diseases that affect the roots will be greater in number this year as well. Hopefully we dry out soon before this becomes a bigger problem. Pollinators are limited when the rain comes, and because of this we should expect lower pollination rates for our vegetables for the time being. 

Your plants may appear to have the lower leaves yellowing. This is normal when they are given too much water. Once again there is no way to stop the rain so just hang in there. Yellowing can also be a symptom of nutritional deficiency (particularly nitrogen). Rain continually washing through the soil many times can wash away nutrients. This is called leaching. You would be wise to put some fertilizer down to replace what was lost, but try and not put it down before a big rain storm. Organic fertilizers tend to work better in this case as they are less prone to leaching.

Another thing to watch out for that you can do something about, are the weeds! The moisture and warm soil will help them germinate as well. Weeds may outgrow our plants in certain conditions. Get out there while the weeds are still small with a stirrup hoe or any hoe you prefer and get them before they get too big. When they are small, the hoe can cut or disturb weeds in a way that kills them. In many cases, if left unchecked, the weeds will grow taller than our plants and shade them out. A few weeks from now our prized plants may be totally outcompeted! Manually remove any weeds too big to hoe up. The wet ground usually makes weeds easier to pull so at least there is some good that comes from all this precipitation.

Over saturated ground may also cause trees to uproot – especially pine trees. Be very careful if you see trees that seem to be leaning over. Hard, frequent rain can also cause washing out of the yard where the grass may not have been that thick.

Tall annual and perennial plants may also get pushed over by the heavy rains. You may be able to tie them up with some string, as they probably will not stand up on their own again this year. If perennial, they will come back next year and have a normal, upright growth pattern so no worries there.

Hopefully this blog helped you understand what is going on around you. With the exception of weeding, there is not much we can do about it other than pray it stops raining so much! This will all end sooner or later and will be a distant memory. I guess we should be happy we did not have to lug around the garden hose. Be ready to fertilize when the rain ends and tie up some of your prized plants. This is all part of what we have to deal with when gardening. In many respects, although outside of the norm, it is nothing new. Maybe one day soon the lawn will be dry enough to mow!
