A bed watered for its vegetables is too wet for its Mediterranean herbs. Tomato, pepper, cucumber and basil want the soil kept steadily moist, about an inch a week; rosemary, sage, thyme, oregano and lavender want it to dry between waterings. One bed gets one regime, and whichever way it is watered, half the planting suffers.

How it works
The vegetables' yield and fruit quality depend on steady soil moisture, so the bed is irrigated to keep it moist. In that same soil the herbs' root zone never dries, oxygen is starved and the roots and stem base rot - the failure the herb rule describes. Watered for the herbs instead, the vegetables run short at fruit set.
What to do about it
Give the herbs their own bed or container beside the vegetables, with sharp drainage - the dry herb bed. If they must share, put the herbs at the highest, driest edge and water at the base of the vegetables only.
How much it matters: No figure is stated or invented. The two regimes are each well documented; the conflict is the inference that one bed cannot hold both, and the rule advises rather than blocks because a gardener can water by hand at the base.
The evidence
Evidence: confirmed against 6 sources in the research-based literature.
the 6 sources
Univ. of Minnesota Extension, 'Watering the vegetable garden', extension.umn.edu/garden-and-home/yard-and-garden/gardening-in-minnesota/watering-the-vegetable-garden (fetched in-container 2026-09-02; read by the maintainer 2026-09-02): 'The vegetable garden needs one inch of rain per week'; 'Water gardens on sandy soils twice a week, supplying one-half inch of water (31 gallons per 100 square feet) each time.'
Univ. of Minnesota Extension, 'Growing tomatoes in home gardens', extension.umn.edu/vegetables/growing-tomatoes (fetched in-container 2026-09-02; read by the maintainer 2026-09-02): 'One inch of rainfall or irrigation per week is ideal.'
Clemson HGIC, 'Pepper', hgic.clemson.edu/factsheet/pepper (fetched in-container 2026-09-02; read by the maintainer 2026-09-02): 'Water sufficiently to moisten the soil to a depth of at least 6 inches'; 'To prevent blossom end rot, keep the soil uniformly moist, but not saturated.'
Clemson HGIC, 'Cucumber', hgic.clemson.edu/factsheet/cucumber (fetched in-container 2026-09-02; read by the maintainer 2026-09-02): 'Practice good cultivation and provide adequate water to moisten the soil to at least a 6 inch depth.'
Clemson HGIC, 'Basil', hgic.clemson.edu/factsheet/basil (fetched in-container 2026-09-02; read by the maintainer 2026-09-02): 'Water the plants regularly, but do not over-water, and do not let the plants stand with water in their saucers'; Univ. of Minnesota Extension, 'Growing basil in home gardens', extension.umn.edu/vegetables/growing-basil: 'water deeply every seven to ten days to insure the roots are receiving enough moisture.'
The low side is the Mediterranean herb rule's own verified sources (Clemson HGIC 'Herbs'; Univ. of Maryland Extension 'Care of Herbs', both read 2026-08-22): 'Herbs will not grow in wet soils'; 'grow best in dry, sunny areas in well-drained soil'; and its remedy, 'Let the soil dry between waterings'.
Where this rule stops
Fires on the water_need field, which today carries only the nine species the sources name; a bed of species without the field is silent, not approved. The field grows as each species is sourced. The low side reuses the Mediterranean herb rule's own read sources; the steady side is one page per vegetable.
Change history
Every change to this rule is one commit. This is what the project's version history records — the date and the reason — not a summary of it.
- rules: another rule here promoted to verified on the maintainer's read (invariant 4)
- rules: another rule here - one bed, two watering regimes (O133 step 2b, maintainer-approved); water_need on nine species
