Persimmon grafting




Persimmon grafting 

🌱 Best Time to Graft Persimmon in Los Angeles 

👍 Primary Window (Recommended) 

Late winter to early spring — just before the buds begin to break dormancy. 

• This is when the tree is waking up, bark begins to slip, and the rootstock’s sap starts flowing — ideal for cambium joining.  

In Los Angeles, this typically corresponds to:  Late February through April (spring warming, no frost risk). 

Because LA has mild winters, you can begin grafting earlier in this window than in colder climates. 

📌 Why: Dormancy plus warming improves callus formation and union success — grafts heal faster and growth starts soon after.  

🪴 Alternative Approaches (Experienced Grafters) 

Some growers in mild climates (like LA) report grafting a bit later — like late April to May — when the rootstock has leafy emergence yields higher success.  

Bark grafting: slightly later (when bark slips easily). 

Whip & tongue / wedge grafting: earlier in spring. 

Bud grafting (chip/T-bud): sometimes done later when active growth begins.  

👉 For beginners, the classic late winter-early spring timing is easiest and most reliable. 

✂️ Best Grafting Methods for Persimmons 

1. Whip & Tongue Graft 

Best if rootstock and scion are similar in diameter. 

Provides excellent cambium contact and a strong union. 

Great for young trees and small diameter wood.

2. Cleft or Wedge Graft 

Good when rootstock is larger than scion. 

Simple and widely used in nurseries.  

3. Bark Graft 

Useful when bark begins slipping in active growth. 

Works well on larger branches or top-working existing trees.  

4. Chip Bud Graft 

A bud instead of a longer scion wood; often done when active growth has started. 

Handy when scion wood is limited.  

 

👉 Whip & tongue and wedge/case grafting are most common for persimmons in professional nurseries.  

🔧 Step-by-Step (Professional Tips) 

-Prepare Scion Wood 

Cut healthy 2–4 bud wood from the desired variety while dormant (late winter). 

Store in moist medium (wet sand) in refrigerator until graft time.  

-Choose Rootstock 

Young seedling or existing tree branch of compatible persimmon (Asian or American depending on scion).  

-Match Diameters 

Scion and rootstock of similar size give the best cambium contact.  

-Make Clean Cuts 

Use a sharp, sterilized grafting knife. 

Make precise •interlocking cuts (whip & tongue), •wedge cuts, or •T-cuts for bark grafts.  

-Align Cambium Layers 

The cambium (green layer under bark) must touch on both scion and rootstock.  

-Seal & Support 

Wrap union with grafting tape or parafilm to keep moisture in and pathogens out. 

Optionally paint large cuts with wax or wound sealant.  

-Keep graft shaded and soil evenly moist. 

Remove suckers from below the graft union so energy goes into the new scion.  

🌡️ Climate Tips for Los Angeles 

No heavy frost means you can graft earlier than in colder zones. 

Avoid hottest summer months (heat stress reduces success). 

📌 Summary 

When to Graft in LA 

Late Winter → Early Spring (Feb-Apr)  

Why This Timing 

Dormant rootstock + beginning sap flow helps union. 

Preferred Methods 

Whip & tongue, wedge/cleft, bark (when bark slips)  

Key for Success 

Good cambium contact, wrapped seal, clean tools

BEST WAY TO GRAFT FUYU PERSIMMON (HOME & NURSERY METHOD) 

🏆 Recommended Method 

👉 CLEFT (WEDGE) GRAFT 

This is the most reliable and easiest method for persimmon, especially if: 

Your rootstock branch is thicker than the scion 

You want high success rate 

You are not a professional grafter 

Most nurseries use this method for persimmon. 

 BEST TIME (VERY IMPORTANT) 

Late February to March in Los Angeles 

 Rootstock: just waking up 

 Scion wood: still dormant 

 Weather: warm days, cool nights 

 Don’t graft in summer heat 

 Don’t graft when scion is already leafing out 

🪵 STEP 1: COLLECT SCION (FROM FRIEND’S TREE) 

When: 

Late winter (Feb) 

Early morning is best 

How: 

Choose 1-year-old wood 

Thickness: pencil size 

Length: 6–8 inches 

Must have 2–4 healthy buds 

✂️ Cut clean with sharp pruners 

Storage (if not grafting same day): 

Wrap in slightly damp paper towel 

Put in zip-lock bag 

Store in refrigerator (NOT freezer) 

🌳 STEP 2: PREPARE ROOTSTOCK 

Use persimmon seedling or branch 

Diameter: ½–1 inch is perfect 

Cut branch straight across 

✂️ STEP 3: MAKE THE CLEFT GRAFT 

1️ Split the rootstock 

Use grafting knife 

Split down the center 1–1.5 inches 

2️ Prepare the scion 

Cut the bottom into a sharp wedge 

Two flat sides 

Buds pointing up 

3️ Insert scion 

Insert scion into split 

IMPORTANT: 

Align cambium layers (green layer under bark) 

👉 Even one side aligned is enough 

If rootstock is thick → insert two scions, one on each side 

🔒 STEP 4: SEAL & WRAP 

This step decides success or failure. 

Wrap tightly with: 

Grafting tape or 

Parafilm or 

Electrical tape (temporary) 

Seal all exposed cuts with: 

Grafting wax or 

Tree seal or 

Melted candle wax (old-school but works) 

 Do NOT leave exposed wood 

🌿 STEP 5: AFTERCARE (CRITICAL) 

First 4–6 weeks: 

Keep soil slightly moist 

Protect from strong sun & wind 

Remove all shoots below graft 

Success signs: 

Buds swell in 2–4 weeks 

Leaves appear shortly after 

If both scions grow → later keep the stronger one 

🚫 COMMON MISTAKES (AVOID THESE) 

 Grafting in hot weather 

 Using old or dry scion wood 

 Poor cambium alignment 

 Not sealing the graft 

 Letting rootstock shoots grow 

🌟 SUCCESS RATE 

With this method in LA: 

70–90% success for beginners 

Higher if weather is mild 

🧠 PRO TIP (From Nurseries) 

Morning grafting is best 

Cloudy day is perfect 

Disinfect knife with alcohol between cuts 

 SIMPLE SUMMARY 

 Use cleft (wedge) graft 

 Graft late Feb–March 

 Use 1-year wood from fruiting tree 

 Seal well 

 Remove rootstock shoots
