Bad Soil Drainage
I'm having soil drainage issues. I was planting a flower bed near the foundation of my house. I dug a few holes (6-7 holes about 8" deep) and it rained afterwards.
The next day 1 hole was empty/dry as I expected but the rest were still full of water. It took them 2 days to completely drain out.
I held back on planting since I'm worried that I'll just wind up killing the plants.
Is there anything I can do to improve drainage?
Someone told me to dig deeper add a little sand and some humus to improve drainage of the soil. Is that all or what are other things to do?
Incidentally we had really bad rains a year ago and the same side of the house's basement got flooded (not sure if the two are related)
