Typically a close mowing favors grasses as they tolerate it better (you are still leaving photosynthetic leaves behind, and new leaves have already started to emerge before you mowed). Some broadleaved plants have also adapted to close haircuts, like buttercups (or dandelions, ground ivy, etc) White clover tolerates close cutting better than any other clovers because of its growth habit, but you have to have a white clover that grows shorter than the lawn gets mowed, otherwise you end up with stems that have no leaves, which is clearly a competitive disadvantage for the clover.
So, yes, mowing height can definitely have an influence on the species present. But you'll only see species emerge that are already there to do so. As said above, you may need to buy some clover seed. If you like to mow low, make sure you get a dutch white clover variety (not actually necessarily seed from the netherlands, that's just the descriptor of shorter varieties. Someone like Rob R might buy a ladino type clover variety for their pasture because they are taller and yield more biomass).
You also might need to pull established buttercups if you want to lessen their presence...
Another thing to check on is the pH of your lawn soil. legumes won't tolerate much acidity at all, and cannot chemically fix nitrogen if they aren't in the correct pH. |
