WATER NEEDS: Plants may need up to 1.5” water/week as needed during hot periods for plants with a spread of 12” or more. During chillier seasons, 3/4” water/week may suffice.
For small seeds (planted 3/4” depth or less), immediately after planting the seed, apply from 1/2” to 3/4” of water (in the planting bed) to settle the soil and to start seed germination.
For larger seed crops, water a few days before seeding and water to a depth of 2 or more inches after planting the seeds.
Transplants require adequate soil moisture. Water a few days before transplanting. A light watering of 1/2’ to 3/4’ will help young roots after transplanting.
The soil must have sufficient moisture for seed germination and vigorous root growth. Frequent, light irrigation can result in shallow root systems, causing stress during dry periods. Once established, deep, infrequent watering is better once plants.
