This year I’ve learned it is possible to get too much of a good thing. We’ve seen a lot of rain this year and it has caused problems we don’t normally see.
One problem with too much rain is that it causes the soil to be saturated or waterlogged. The water does not allow air to get to the roots. When the roots do not get air, they do not function correctly and it affects the entire plant. Sometimes plants will recover, sometimes they will not. Time will tell. The best thing to do in this situation is to wait and see if it recovers. We do not recommend fertilizing because this can aggravate the problem. The roots are not functioning and fertilizer can cause root injury. Just be patient and let nature take its course.
Another problem with excessive rain is excessive growth. The yards I’ve seen are doing very well and need to be mowed between every shower. Many of the bushes, shrubs and trees that are not waterlogged are growing well. This excessive growth can tempt homeowners to cut back the shrubbery. Pruning is okay to do before July. However, if you have not pruned yet, we recommend waiting until winter to remove excessive growth. We recommend not pruning after July because pruning stimulates growth and new growth the may not have enough time to become woody (harden off) before frost.
The last major issue with excessive rain in the home landscape is weeds. Many landscape beds are full of annual weeds because the of the wet season. These should be hand pulled or otherwise removed before they make seed. Letting them produce seeds will make the problem worse for next year. Removing weeds and refreshing the mulch in landscape beds will keep the landscaping looking attractive and maintained.
