Prof. Charles Hartman, Ph.D.Soil Conditions. Conditions.The best results will not be attained on light, sandy soils lacking in organic matter, or on heavy, retentive, ill soils. A deep, rather rich, well-drained soil is essential. On clayey soils, it is necessary to incorporate earth with sand or peat to prevent waterlogging.
Drainage Improvement
- Incorporate 3-4 inches of coarse sand into clay soils
- Create raised beds 12 inches high for wet areas
- Install French drains in poorly draining locations
- Avoid compacting soil around plant bases
pH Management
- Test soil annually using reliable testing kits
- Add lime to raise pH if below 6.0
- Apply sulfur to lower pH above 7.0
- Maintain ideal 6.5 pH for nutrient availability
Organic Enrichment
- Mix 6 inches of compost into planting area
- Add aged manure before planting season
- Use worm castings for slow-release nutrients
- Apply 2-inch mulch layer to conserve moisture
Nutrient Balance: Fertilization. Add a balanced 10-10-10 NPK fertilizer when planting. Side-dress once a month with compost tea during active growth. Avoid adding so much nitrogen that it encourages leafy growth at the expense of producing buds. Have your soil tested every spring so that you can adjust your nutrient applications for that year.
Implement effective moisture management. "Water deeply" 2-3 times a week, 1-1.5 inches total. For consistent root-zone hydration, install drip irrigation to "keep it moist." Monitor soil moisture at a 6-inch depth and mulch with straw to retain moisture and reduce evaporation.
Yellow leaves may indicate problems with drainage or nutrient deficiency, so address soil issues promptly. Heavily compacted soil would benefit from aerating it with a broadfork. Salt buildup will appear as a white crust on the soil - flush it with plenty of water. Change where you plant your artichokes every 3 years.
