Fruit Tree Planner

Plan compatible pollination partners, compare varieties, and understand flowering compatibility for apples, pears, plums, blueberries, cherries, and more.

Step 1

Choose a fruit type

Start here. The helper uses different rules for apples, plums, blueberries, kiwis, and other fruit groups.

41 options available.

Type to narrow the list.

Selected fruit

Plum

21 tracked varieties

Plums are where pollination gets trickier. European plums usually need European partners, Japanese plums usually need Japanese partners, and hardy native or hybrid plums often need another hardy hybrid or native-type partner.

Keep partner trees within about 50 feet if you can. Plum bloom is early, so having a well-matched partner improves the odds in cool spring weather.

Step 2

Choose what you want to check

Current goal

What to do

Plums are picky about pollination, so matching the right plum group is important.

About this variety

Castleton is sweet with a soft acidic lift, with firm, dense flesh and medium fruit. Choose it for drying, baking, prune-style preserves, and structured fresh eating, but skip it if you want a soft, dripping dessert plum or the earliest plum on the tree. It usually ripens around early to mid September.

This shows compatible pollinators. Choose based on flavor and harvest timing.

Usually grown in USDA zones 5-8.

Castleton can fruit alone, but it still benefits from a partner. Plums are picky about pollination, so matching the right plum group is important. It flowers in bloom group 3, which is mid bloom, which is worth knowing if you add a second tree later. Usually grown in USDA zones 5-8.

No single variety stands out as the obvious partner, but that is not a problem here: Damson, Green Gage, Italian Prune / Fellenberg, Mount Royal, and Stanley all bloom close enough to work. Pick whichever your nursery actually carries. Keep partner trees within about 50 feet if you can. Plum bloom is early, so having a well-matched partner improves the odds in cool spring weather.

One thing to keep in mind. Do not casually mix European, Japanese, and hardy hybrid plums. Plum group matters.

To put that into practice: at a minimum, plant two compatible plums from the same pollination group, such as European with European or Japanese with Japanese. Better still, use two or three plums in the same group with overlapping bloom so frost, poor weather, or shy bee activity does not ruin fruit set. If you only have room for one plum, choose a self-fruitful European type, but still plan for a second compatible plum later if yield matters.

Good backups

These are still useful choices when the very best option is not available at your nursery.

Damson

European plum

Mid bloom - mid bloom
Good backup

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Zone unknownSame bloom window
Why choose this?

Damson is tart-forward with sharp acidity, with firm, dense flesh and small fruit. In this group, this brings more acidity and bite than most of the others shown. Choose it for jam, jelly, chutney, and cooks who want strong plum intensity, but skip it if you want fresh snacking if you want a sweet, mellow dessert plum. It usually ripens around early to mid September, later than most of the others shown.

Green Gage

European plum

Mid bloom - mid bloom
Good backup

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Zone unknownSame bloom window
Why choose this?

Green Gage is very sweet with low acidity and real depth, with soft, juicy flesh and medium fruit. In this group, it is one of the softer, juicier choices, so it leans more toward fresh eating than long holding. Choose it for premium fresh eating, jam, and growers who care most about dessert quality, but skip it if you want heavy hauling, long holding, or batches where you want large, easy-to-pit fruit. It usually ripens around mid to late August, earlier than most of the others shown.

Italian Prune / Fellenberg

European plum

Mid bloom - mid bloom
Good backup

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Zone unknownSame bloom window
Why choose this?

Italian Prune / Fellenberg is sweet with just enough acidity to stay lively, with firm, dense flesh and medium fruit. In this group, it is one of the firmest choices, so it handles baking, slicing, or holding its shape better. Choose it for drying, baking, preserving, and late-season kitchen plums, but skip it if you want a juicy early dessert plum for eating out of hand. It usually ripens around early to mid September, later than most of the others shown.

Mount Royal

European plum

Mid bloom - mid bloom
Good backup

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Zone unknownSame bloom window
Why choose this?

Mount Royal is sweet with a soft acidic lift, with juicy flesh with moderate firmness and medium fruit. In this group, this is one of the richest-tasting options. Choose it for fresh eating, preserves, and cold-climate European plum plantings, but skip it if you want oversized show fruit or very soft dessert flesh. It usually ripens around late August to early September, in the middle of this group.

Stanley

European plum

Mid bloom - mid bloom
Good backup

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Zone unknownSame bloom window
Why choose this?

Stanley is sweet with just enough acidity to stay lively, with firm, dense flesh and large fruit. In this group, it is one of the firmest choices, so it handles baking, slicing, or holding its shape better. Choose it for drying, canning, baking, and dependable all-purpose home harvests, but skip it if you want growers chasing the richest dessert-style sweetness or a very early crop. It usually ripens around early to mid September, later than most of the others shown.

Avoid

These are poor bets to rely on for this variety.

Why choose this?

Santa Rosa is lightly sweet with a definite tart edge, with juicy flesh with moderate firmness and large fruit. In this group, this is one of the richest-tasting options. Choose it for fresh eating, baking, preserves, and all-purpose Japanese plum harvests, but skip it if you want the very earliest crop or a dry-fleshed prune plum. It usually ripens around early to mid August, in the middle of this group.

Satsuma

Japanese plum

Mid bloom - mid bloom
Avoid

Blooms in the same window. Zone fit is unknown or not a major tie-breaker here.

Waneta

Hardy hybrid plum

Early bloom - early bloom
Avoid

Blooms close enough to overlap in many home plantings. Zone fit is unknown or not a major tie-breaker here.

Zone unknownNearby bloom window

These are not in the same pollination group.

Why choose this?

Waneta is lightly sweet with a definite tart edge, with juicy flesh with moderate firmness and medium fruit. In this group, it is one of the firmest choices, so it handles baking, slicing, or holding its shape better. Choose it for fresh eating, preserves, and colder sites where you still want solid dessert fruit, but skip it if you want growers who only want ultra-soft dessert texture or very early ripening. It usually ripens around late August, in the middle of this group.

Minimum planting guidance

Use the minimum, ideal, and fallback plan to size the planting to your space and goals.

Minimum setup

Plant two compatible plums from the same pollination group, such as European with European or Japanese with Japanese.

Ideal setup

Use two or three plums in the same group with overlapping bloom so frost, poor weather, or shy bee activity does not ruin fruit set.

Fallback plan

If you only have room for one plum, choose a self-fruitful European type, but still plan for a second compatible plum later if yield matters.

Important notes

These notes keep the key cautions and practical details easy to scan.

Warnings

Do not casually mix European, Japanese, and hardy hybrid plums. Plum group matters.

Helpful notes

Keep partner trees within about 50 feet if you can. Plum bloom is early, so having a well-matched partner improves the odds in cool spring weather.
