Prof. Samuel Fitzgerald, Ph.D.The proper watering frequency for Kale can not only affect the plant health but also the quality of your harvest. Water every week or two, providing 1-2 inches of water during deep soaking sessions, which penetrate 6 inches into the soil. In temperatures above 85°F (29°C) during heat-waves, increase watering to 3 inches per week, to avoid wilting and developing bitter-tasting leaves. Remember, moisture control prevents stress and protects against root rot.
In-Ground Beds
- Deep soaking: Water slowly for 30 minutes twice weekly
- Moisture test: Soil should form ball when squeezed
- Mulching: Apply 3-inch straw layer to retain moisture
- Dry signs: Wilting leaves indicate immediate need
Container Plants
- Daily check: Insert fingers 2 inches deep each morning
- Drainage: Ensure holes prevent water accumulation
- Hot weather: Water twice daily above 90°F (32°C)
- Weight test: Light pots signal watering necessity
Use morning watering routines for efficiency. Watering between 5:00 and 8:00 AM can reduce evaporation loss by 30% compared to watering mid-day. Soaker hoses or drip watering systems can send water directly to the root zone. I avoid evening watering, which allows fungal diseases to grow overnight. Time is key to ensuring the efficiency of each drop.
Stop *common watering mistakes* that harm plants. Overwatering leads to yellow undersides and slowed down growth. Underwatering causes it to toughen and become bitter. Uneven moisture will cause bolting. I use inexpensive moisture meters for precision. I also adjust my schedule weekly based on variations in rainfall and temperature.
