Bee Lawn has Weeds #887030

Asked October 03, 2024, 11:20 AM EDT

Hello! We planted a bee lawn two falls ago, which covers about 1/4 acre or so. Last summer it was getting established and was looking good for its first year. This summer it came in amazing, the clover flowered and looked fantastic. We had so many bumblee bees, it was great. Then about August, the area seems to have turned to be a lot of weeds. You can't see the clover as obviously as we could before and there are tall clumps of a grass looking 'weed'. We also have another 1/4 to 1/2 acre of prairie grasses that we also had planted. I hope to get advice on what we should do to bring back the bee lawn as before, or if any of what have now is normal and ok. Thank you!

Thanks for the question.

Getting rid of weeds in a bee garden requires gentle and environmentally friendly methods to protect bees and other beneficial insects. It will be difficult to find chemical herbicides that would only kill the weeds and not the bee flowers. Here are some possibilities:

1). Manually pulling weeds is a bee-safe option. Do this after rain or watering to loosen the soil, making it easier to remove the roots. You could also use a sharp hoe to cut weeds just below the soil surface. Regular shallow hoeing prevents weed growth without disturbing the soil too much.

2). Spread a thick layer of organic mulch (like straw, wood chips, or leaf mold) around desirable plants. This suppresses weeds by blocking light and improves soil health over time. Place sheets of damp newspaper or cardboard under the mulch for added weed control. However, looking at your pictures and the size of things, this may be neither practical nor realistic.

3). A 5% white vinegar solution can act as a natural weed killer. Most commercial vinegars are 5%. Look on the label to confirm this. Spray this solution directly onto weeds on sunny days, avoiding contact with desirable plants. Be careful to use it selectively, as vinegar can harm any plant it touches.

You may want to ask yourself the question what is to be gained by eliminating all the weeds? Some of them may be attracting pollinators. See the following for further information:

Thank you so much for the quick response!  Are you able to tell by the pictures which are the obvious weeds that we should pull?  I attached a few more pictures that I took this morning. Besides the clover, I don’t think there was much else that bloomed. 

 

Are there any grants that help with bee lawns after they have been planted?  Or are they only before you go to plant? 

 

Thank you again for time and expertise!

Thanks for your response.

Do you know what you planted in addition to the white clover? Perhaps you used a mixture of seeds? I ask this because if you planted a mixture of seeds, then it becomes very difficult to identify what is a weed and what is something contained in the mixture.

The grass-like plant is perennial rye grass. Sometimes it is included in bee garden seed mixtures and sometimes it is not. The broad leaf plant appearing in clumps is called Self-Heal (Prunella vulgaris). It, too, is typically part of a bee garden seed mixture. Here is some information about it:

https://www.minnesotawildflowers.info/flower/self-heal

https://apps.extension.umn.edu/Garden/diagnose/weed/broadleaf/creeping/healall.html

In short if you planted a mixture of seeds, it will truly be a judgement call as to what is desirable and what is a weed.

Here’s my suggestion. Starting in spring 2025, sow seeds of specific plants that you would like to have in your bee garden. By knowing what you want and what you put down will enable you to discern the plants that are unwanted. See the following:

https://www.kglandscape.com/pollinator-plants

https://extension.umn.edu/lawns-and-landscapes/flowers-pollinators

With respect to availability of funds, you may wish to contact the Dakota County Extension Office. They may be familiar with any county and/or state funding opportunities:

Looking over what I’ve just written, I think the bottom line is that you should identify ten to fifteen different plants that you would like to have in your garden. Get seeds for these plants and sow them next spring. By knowing what you want, it becomes much easier to identify plants that you don’t want.

Good luck! Get back to us with any additional related questions. Thanks for consulting us.

THANK YOU!!

 

This is fantastic information.  I really appreciate your responses and valuable information.

 

We did use a mix, but I am not sure off hand what it was.  

 

Thanks again!
