What's the hardest part of the gardening process?

I think feeding your plant is one of the most crucial step and the most common error that most of the gardeners make. Most soil has no nutrients. It is you who have to make it fertile by mixing fertilizers, whereas some have fertilizers mixed in it. If your potting soil doesn’t have fertilizers already in it, you will need to add or mix fertilizer. Once you have mixed the fertilizer with the soil, water them with a diluted liquid fertilizer every week.

 

I think the hardest part is prep. If you do not weed out you garden at the end of the growing season then you need to do it at the start. At that time you'll find weeds wanting to grow and doubling your prep load. Also for me, I have a 3year old sidekick who does not have patience for the 5 hrs spent removing all I left at the end of the season.
Then comes combating the weeds throughout the season. This task is not as difficult if you grown in a small space or containers.
The satisfaction of feeding your family or yourself from the sweat of your brow is a great feeling!
