Plant some flowers – together.
For those of us on the “upper” part of the world, spring is either here or well on its way. Why not do some yard beautification with your bride? Plan it together, go shopping together, and plant together. (And clean up together? ;-) )
The “big box” garden centres have everything you need, with tags on plants that help you know how much sun and water each plant needs. Store staff is often very knowledgeable, so ask questions.
If you don’t have a yard, you can do something in a sunny window, or on a patio or balcony. Get a waterproof nice looking container, and then put one or more posts or boxes with drain holes into the outer container. Plant in the inner containers, using a good potting soil, and finish with a bit of mulch to make the top look nice. Water thoroughly when the soil is dry, enough for a bit to run through. A powdered plant fertiliser added to the water will help significantly.
And yes, I was a landscaper in a former life! A note on retail garden centres – you will get the best selection, and freshest plants, on Thursday afternoon or Friday morning.
