I am going to share my success with how to grow zucchini in containers. When you garden on a small urban lot you have to get creative in order to grow as many edible plants as you can. Many of our planters are root bound from all the foundation plants and trees so I have to garden above ground.
Growing zucchini in southern California can provide you with fresh squash 6-8 months of the year with our long growing season.
1. Fill your container with potting soil and mix in a time release fertilizer if you are not going to feed your plant. I make compost tea but will mix in a little fertilizer when planting.
2. Plant either a start from the nursery or plant a small mound of three seeds. I then thin to one seedling. Now water daily if you do not get summer rain like us. Feed regularly.
3. As the flowers start appearing I will self pollinate to ensure I get a lot of zukes. I take the male flower and pollinate the female flowers growing on the tiny new baby zucchini.
4. Now just pick and enjoy your zucchini making sure to water daily if temps are high. I prefer to pick mine when they are small rather than too large but sometimes one gets away from you and it is time for zucchini bread. Here are my tips on how right way to harvest squash.
