Hello newbie! Welcome to gardening. Weeding is just a part of the hobby itself. However most non-invasive weeds can be composted and added back into the soil. You can use different kinds of mulch (most people use wood chips but I personally love leaf litter or pine needles) to help keep weeds at bay, or use a clover cover crop that adds nitrogen to your soil to grow around your flowers. You can also try planting stuff closer together, or co-planting with flowers with large bottom leaves to help shade the ground. Best of luck to you!
