What are the most important things to consider in growing plants for a beginner gardener?
Do research on all plants you want to grow, and only grow what you will eat.
1. Research the growing conditions, how to cook, how to harvest, and how many plants per person.
2. Lay out a garden design - doesnt have to be complicated. You can even use a container garden.
3. Separate plants by shade, full sun and partial shade. Also use companion planting.
4. Invest in good compost and soil, as well as a simple fertilizer such as Alaska Fish Emulsion, which is very concentrated and super cheap. You can mix Black Kow ($6.00 at Lowes) with Miracle Gro together. I would even add in Perlite. Be creative and use whatever is most plausible or free!
5. Talk to fellow gardeners.
This are just a few ideas.
