Germination or transplant recoveryFine roots, even moisture, mild fertility
Start Lettuce in fine, biologically active soil with gentle nutrition so roots expand without salt stress.
Crop growing guide
Lettuce
Lactuca sativa
A shallow-rooted leafy crop needing cool conditions, clean water, and gentle continuous nutrition for crisp leaves.
Lettuce grows quickly and stores much of its harvest as water-filled leaf tissue. Excess heat, drought, salinity, or late nitrogen can cause bitterness, tipburn, or weak heads.
For practical cultivation, Lettuce needs its light, water, root-zone aeration, and nutrition managed as one system. The guidance below organizes those needs by growth stage; final field or container rates should follow the product label, plant size, local conditions, and soil or media analysis.
Ideal growing conditions
- Light
- Full sun in cool conditions; light shade helps protect leaves in hot sites.
- Climate
- Cool to mild growing conditions with steady air movement.
- Water
- Consistent shallow-root moisture; drought quickly reduces leaf quality.
- Soil
- Moist but well-drained, fertile loam with readily available organic matter.
- Soil pH
- 6.0–7.0
Nutrition by growth stage
Leaf production
Main canopy-building periodNitrogen balance, magnesium, continuous growth
Use small, regular inputs to keep Lettuce growing evenly. Overfeeding produces weak, watery tissue and can reduce keeping quality.
Harvest maintenance
Final growth or repeated cuttingLeaf quality, recovery, clean water
Keep moisture and nutrition stable before harvesting Lettuce; stop corrective feeding too close to harvest.
Alitura fertilizer program
Match each product to the crop stage and root zone. Final rates should follow the product label, soil condition, and local agronomic advice.
Asparagus Special Mix
Special organic blend formulated for vegetable plant growth and crop quality.
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Leaf production · Harvest maintenance
Asparagus Special Mix organic nutrition can support Lettuce when its use follows crop stage, soil condition, and the product label.
Best timing
Introduce during active growth and the higher-demand stages listed above; avoid a large corrective dose close to harvest or dormancy.
How to apply for this crop
Apply to moist soil around the active Lettuce root zone, keep material away from stems or crowns, water in, and adjust the amount to plant size and field or container conditions.
General product guidance
Apply around the active root zone or mix into the planting media according to the package label, then water lightly. Adjust the amount to plant size, soil condition, and crop stage.
NPK 5-5-5
Alitura's Reserve
Most Balanced NPK 5-5-5 Organic Nutritional Fertilizer
From IDR 28.000 / Kg(Packaging 20Kg)
Recommended for
Establishment · Leaf production
balanced soil-building organic nutrition provides a defensible foundation for Lettuce without replacing soil or leaf analysis.
Best timing
Use during soil preparation, establishment, or recovery, then reassess before the next growth stage.
How to apply for this crop
Spread evenly through the cultivated root zone or media, mix lightly where appropriate, and never pile fertilizer against Lettuce.
General product guidance
Use Alitura's Reserve as a base feed at planting and as a top-up through the growing season. As a general guide, work a small handful into the soil around each plant or mix it into potting media before planting, then reapply every 4 to 6 weeks during active growth. For garden beds, broadcast evenly over the soil surface and lightly incorporate, then water in well. Powder works best mixed into soil or media. Always water after applying and adjust the amount to plant size and soil condition.
Mistakes to avoid
- Overfeeding nitrogen and producing weak, watery leaves.
- Letting shallow roots dry between irregular watering cycles.
- Applying fresh fertilizer too close to harvest instead of maintaining steady fertility earlier.
- Keep nutrient solutions or fertilizer away from the crown where salts can collect and burn young leaves.
