Best Plants for Plant-tone Fertilizer
Plant-tone is best for many annual and perennial flowers, vegetables, trees, and shrubs, including arborvitae and several common landscape plants. It is Espoma’s all-purpose organic plant food, but a plant’s exact species can matter more than its broad category: blueberries, asparagus, anemones, and African violets each have a better-matched Espoma product. Use the plant name first, then choose the product and application method that fit the planting situation.
What Plant-tone Is Designed to Feed
Plant-tone is an all-purpose fertilizer made for organic gardening. Espoma formulates it with natural and organic ingredients, humates, and beneficial microbes for use on flowers, vegetables, trees, and shrubs.
That broad use makes it useful in a mixed garden: a vegetable bed, perennial border, newly planted shrub, or container can all potentially use Plant-tone. It is not, however, the best automatic choice for every plant that happens to be edible, flowering, evergreen, or grown in a pot.
The product name also does not mean it is a plant-light product or a treatment for leaf color problems. Plant-tone supplies plant nutrients; it does not replace choosing the right light exposure, watering routine, soil conditions, or plant species for the site.
Choose the Right Espoma Fertilizer for the Plant
Start with the plant’s actual name rather than choosing fertilizer only by whether it is a flower, vegetable, or shrub. This table matches common plants and planting situations with the appropriate Espoma product.
| Plant or Situation | Espoma Product Choice | Selection Reason |
|---|---|---|
| Most flowers, vegetables, trees, and shrubs | Plant-tone | General all-purpose garden fertilizer |
| Arborvitae | Plant-tone | Espoma specifically recommends Plant-tone |
| Blueberries and other acid-loving plants | Holly-tone | Made for acid-loving plants |
| Asparagus | Garden-tone | Espoma lists asparagus as a vegetable match for Garden-tone |
| Anemone bulbs, tubers, and corms | Bulb-tone | Made for bulb-type plants |
| African violets | Violet! | Formulated for African violets |
| An unfamiliar species or cultivar | Check Espoma’s Plant Food Finder | A species-specific match is more reliable than a broad category |
Step 1: Identify the Plant Before Feeding It
Use the plant tag, seed packet, nursery label, or botanical name when possible. This is especially important for shrubs, bulbs, herbs, and perennial flowers that can look similar while having different nutrient and soil preferences.
Espoma specifically matches Plant-tone with alder buckthorn, arborvitae, abelia, ageratum, aster, apple mint, and American hazelnut.
Step 2: Give Species-Specific Products Priority
A named species match is more useful than a broad all-purpose category.
For example, asparagus is a vegetable but has a Garden-tone recommendation. Anemone may be a flowering plant, yet its bulb, tuber, or corm habit makes Bulb-tone the better match. African violets are flowering houseplants, but Espoma directs them to Violet! rather than Plant-tone.
Step 3: Use Holly-tone for Blueberries
Choose Holly-tone for blueberries. Blueberries are acid-loving plants, and Holly-tone is intended for hollies and other plants that prefer acidic soil conditions.
Apply Plant-tone to Each Planting Situation
The amounts below are Espoma’s directions for its own Plant-tone product, not universal rates for every fertilizer brand or formula.
Garden Beds and New Planting Holes
For a garden bed, mix Plant-tone into the top 4 inches of soil at a rate of 4 pounds per 100 square feet. Work it through the planting zone rather than leaving it in an unmixed layer at the surface.
For a new tree, shrub, perennial, or other planting, mix 1 cup of Plant-tone into the soil used to backfill the planting hole. Place the plant, backfill with the amended soil, and firm the soil around the roots.
This approach spreads the fertilizer through the soil where new roots will grow instead of concentrating it in one spot.
Established Shrubs and Trees
According to Espoma Organic, follow the label directions for established shrubs, using the rate based on plant height. Double that rate when the shrub’s drip-line diameter is more than 3 feet. The drip line is the outer edge of the plant’s canopy, where rainfall typically drips from the foliage to the ground.
For example, a shrub with a 4-foot drip-line diameter receives 8 cups because the standard 4-cup calculation is doubled for a shrub wider than 3 feet. Sprinkle the measured amount on the soil around the drip line.
According to Espoma Organic, for an established tree, use 3 pounds per inch of trunk diameter and double the rate for trees with trunks larger than 6 inches in diameter. A tree with a 7-inch trunk, for example, requires 42 pounds under Espoma’s Plant-tone directions. Apply the fertilizer to the soil around the tree’s root zone rather than piling it against the trunk.
Flowers and Vegetables
For established individual flowers and vegetables, apply 1 cup of Plant-tone per plant. Spread it onto the soil around each plant, keeping the fertilizer at the base area rather than on leaves or stems.
This rate is for individual plants. A densely planted bed is usually easier to manage with the garden-bed rate mixed through the top 4 inches of soil before planting.
New and Established Potted Plants
When preparing potting soil for a new container planting, mix 2 cups of Plant-tone into each cubic foot of soil before filling the pot. Blend it evenly through the soil, fill the container, and plant as usual.
For an established potted plant, use 1 teaspoon for each 3 inches of pot diameter. An established plant in a 12-inch pot receives 4 teaspoons. Distribute the measured fertilizer over the potting soil around the plant, then repeat monthly.
Set a Plant-tone Feeding Schedule
Espoma’s Plant-tone directions call for different schedules based on the type of planting:
- Feed trees and shrubs in spring and fall.
- Feed flowers and vegetables once per month during the growing season.
- Feed established potted plants monthly at 1 teaspoon for each 3 inches of pot diameter.
These intervals apply to Plant-tone. Do not assume that Holly-tone, Garden-tone, Bulb-tone, or Violet! use the same schedule simply because they are made by the same company.
Keep a simple record of what was fed and when, especially in gardens with many perennials, shrubs, and containers. I use weatherproof plant labels to mark newly planted shrubs and the month they were fed, because it prevents accidental repeat applications.
Confirm Plant-tone Is the Right Choice Before Adding More
A plant that looks pale, slow-growing, wilted, or damaged does not automatically need more fertilizer. Before making another application, look for non-fertilizer causes such as unsuitable light, dry soil, compacted soil, root damage, or pest injury.
Use this short check to confirm the plant match, application amount, and need for fertilizer before feeding:
- Confirm the plant name and whether it is a flower, vegetable, tree, shrub, bulb, acid-loving plant, or houseplant.
- Measure the fertilizer for the planting situation rather than estimating.
- Monitor the plant’s condition over time.
A healthy fertilizer routine supports plant growth, but correct plant selection, appropriate soil conditions, and steady care are what make that feeding useful.

Yes. Arborvitae is a named Plant-tone match from Espoma. Espoma specifically recommends Plant-tone for arborvitae. Treat an established arborvitae as a shrub: apply 1 cup per foot of drip-line diameter, doubling the amount if the drip line is larger than 3 feet across.
How Do I Feed an Established Plant in a Pot?
Use 1 teaspoon of Plant-tone for each 3 inches of pot diameter, then repeat monthly. A 6-inch pot receives 2 teaspoons, while a 12-inch pot receives 4 teaspoons.
