Detailed Review
Espoma Organic Bulb-Tone 3-5-3 is a specialized plant food crafted for gardeners cultivating seasonal flowers. Formulated for all varieties of fall bulbs like tulips, daffodils, crocus, and hyacinths, as well as spring bulbs like gladioli and lilies, it provides targeted nutrition right where roots develop.
The blend features a 3-5-3 natural and organic fertilizer analysis enhanced with 6% calcium and the proprietary Bio-tone formula. It is an environmentally safe option that contains no sludges or toxic ingredients, making it an approved Organic Input Material for certified organic production.
Using the plant food is straightforward because the formula arrives ready to use with no pre-mixing required. Gardeners place the product directly into the planting hole when setting out new bulbs, or sprinkle it across the soil surface around established plants after flowering, followed by a thorough watering.
As a trade-off, the product requires manual watering into the ground after spreading, and the listed details do not state specific bag weights or square-foot coverage amounts.
