Symptoms of salt toxicity include brittle leaves and brown and dry leaf margins. Roots may die and
plants may be stunted or killed.
Strawberry plants are highly sensitive to salt. Salt toxicity may be caused by high levels of salt
in the soil, poor drainage, excessive application of fertilizer, or the application of fertilizer
to wet foliage. Tests of soil can be used to confirm the source of salt toxicity. If salt accumulation
becomes a problem, use sprinklers to rinse salts from the beds. It is a good idea to sprinkle heavily
at least twice during the summer; do so in the morning so that plants can dry off. Do not use softened
water for strawberries. Water softeners replace calcium and similar ions, which are not harmful to
strawberry plants, with sodium, which is harmful.
