Need curb appeal but nothing permenant

Get some hanging box planters to hang on the outside of the railing, it will make the porch look larger too, put lot of colorful flowers in them! https://www.wayfair.ca/Veradek--Window-Box-Plastic-Rail-Planter-WBRLV36-L349-K~VRDK1070.html?refid=GX114558722710-VRDK1070_20569391&device=c&ptid=173400456800&targetid=aud-175036624590:pla-173400456800&network=g&PiID%5B%5D=20569391&gclid=Cj0KCQjw2pXXBRD5ARIsAIYoEbeRrUq9fZ-GwINhKzLFdedraJDP0XWqCHCafEW5P5rxrMm5s87_B4gaAh01EALw_wcB

ppuba great looking wreath in the front door. and put a few pots of plants on the the steps to your house of the font pourch.

I love yellow flowers for a blue house- in containers

Think about enhancing the curb appeal after dark as well. Is there some kind of an outdoor light by the front door? Are the house numbers visible? If you had an electrical outlet near bushes, you could easily wind some mini lights in the leaves, or in plants near the approach to the front door. This would enhance the curb appeal, as it would instantly give more 'life' to the home.

Put a small bench (brown cover to match the blue sidings) and a plant on the corner.

Nice wreath ,perhaps a pot of flowers and a welcome mat . You don't need a lot.
