A successful garden starts with planning before a single plant goes in the ground. Poor site selection, wrong soil, or overcrowded plants cause most garden failures. This guide walks through every planning decision from choosing what to grow to sizing beds and calculating soil and mulch.
Step 1: Assess Your Site
Sun is the most critical variable - most vegetables and many flowers need 6-8 hours of direct sun daily. Walk your yard at different times of day and note where shade falls. Check drainage - water pooling after rain indicates poor drainage. Note existing trees - their roots can compete for water and some release chemicals that inhibit plant growth.
Step 2: Decide What to Grow
Match plants to your conditions. Vegetables for full sun: tomatoes, peppers, squash, beans, cucumbers. Vegetables for partial shade: lettuce, spinach, kale, herbs. Start with what you'll actually use - a small productive garden beats a large neglected one.
Step 3: Plan the Layout and Size Beds
Use the Garden Area Calculator to size your beds. Standard raised beds are 4 feet wide and 8-12 feet long. Leave 2-3 foot paths between beds. Plan taller plants on the north side so they don't shade shorter plants. Group plants with similar water needs together.
Step 4: Calculate Soil and Amendments
Use the Soil Calculator for raised beds. For new raised beds, plan for Mel's Mix or a 60/40 topsoil/compost blend. For in-ground beds, get a soil test ($15-$30 from your county extension service) before adding amendments.
Step 5: Plan for Water
Most vegetables need 1 inch of water per week. A drip irrigation system ($50-$200 for a basic setup) is the most efficient option. For small gardens, a soaker hose on a timer works well. Plan irrigation layout before filling beds.
Step 6: Calculate Mulch and Weed Barrier
Use the Mulch Calculator for path and bed coverage. For paths between beds, wood chip mulch 4-6 inches deep virtually eliminates weeding. For beds, 2-3 inches of mulch retains moisture and suppresses weeds.
Step 7: Seasonal Planning
Divide your growing season into cool-season crops (spring and fall) and warm-season crops (summer). Succession planting - replacing harvested cool-season crops with warm-season crops - maximizes productivity from limited space. Know your last frost date to time planting correctly.
Pro Tips
- Start small the first year - a 4x8 foot raised bed is manageable and productive.
- Get a soil test before adding amendments.
- Water in the morning - evening watering promotes fungal disease.
- Leave adequate space between plants - crowded plants have poor air circulation.
- Keep a garden journal - noting what worked and when you planted what is invaluable.
