Our Citrus limon Application @ Tough Kraut
We planted three lemon trees at the very start of our journey on the land—each one a lesson in microclimates and tree tenacity. The tree near our mobile home thrives with attention and watering, surrounded by thyme, strawberries, and sword iris. The second, planted on the veggie terrace, endured a brutally cold night that nearly took it down. We feared it was gone, but as every good homesteader knows: never give up on a tree too soon. The third, placed in our food forest area, sadly didn’t survive its first year. So far, no lemons yet—but MuDan’s careful pruning is setting the stage for future growth.
Step-by-Step Growing Guide
Note: Growing lemons in Zone 8a involves troubleshooting frost damage, water access, and pollination. Here’s what we’ve learned—so you don’t have to learn the hard way.
1. Choose the Right Site
Pick a location with maximum sun exposure and wind protection. Near south-facing walls or structures provides warmth and reduces frost risk.
2. Prepare the Soil
Amend native soil with compost, sand, and aged manure. Ensure pH is slightly acidic and drainage is excellent—soggy roots = trouble.
3. Plant the Tree
Dig a hole twice as wide as the root ball. Plant slightly above soil level to encourage drainage. Mulch well but leave a collar around the trunk.
4. Water Consistently
Deeply water 1–2 times per week during establishment. Adjust frequency in winter and summer—avoid shallow, frequent watering.
5. Ensure Proper Pollination
Even though lemons are self-fertile, pollinator presence increases fruit quality. Grow companion herbs and flowers to draw in bees.
6. Prune Annually
Prune in late winter to early spring. Remove dead, damaged, or crisscrossing branches. MuDan has been leading this task at our homestead.
7. Manage Pests and Diseases
Watch for leaf miners, scale, and aphids—especially in spring. Neem oil or horticultural soap helps keep things in balance.
8. Harvest and Store
Expect fruit after 3–5 years. Lemons are ready when fully yellow and slightly soft. Store in a cool, dry place for up to several weeks.
9. Note
If frost hits unexpectedly, wrap young trees in fleece or use water jugs to radiate heat overnight. Even a severely damaged tree can come back!
Kraut Crew Insight
Of the three lemon trees we planted, the one closest to the house is thriving thanks to water and proximity. It’s a reminder: distance matters when daily care is needed. MuDan’s pruning care has also helped shape growth despite no fruit yet.

Herman’s Tough Kraut Field Notes: Solving Lemon Tree Cultivation Challenges
When growing Citrus limon in Zone 8a, you’ll run into specific challenges that require some troubleshooting. Based on real-world experience, here’s a handy FAQ section to help you through the most common lemon tree hurdles.
Q: My lemon tree looks dead after winter. Should I dig it up?
A: Not so fast. Unless the trunk is mushy or split, leave it. One of ours came back after being dormant for over a year. Be patient and scratch-test the bark before declaring it gone.
Q: Why is my tree growing but not fruiting?
A: Lack of fruit is normal in the first 3–5 years. Focus on building strong roots and balanced growth. Ensure enough sunlight and don’t overfertilize with nitrogen—it promotes leaves over lemons.
Q: What’s the best way to protect lemon trees in winter?
A: Use frost blankets, old bedsheets, or even wrap with cardboard at the base. Placing them near stone or thermal mass structures helps too.
Q: My leaves are curling—what’s wrong?
A: Could be citrus leaf miner, wind stress, or inconsistent watering. Inspect for tiny trails or larvae and adjust watering routine accordingly.
Q: Should I mulch my lemon tree?
A: Yes—but keep mulch 5–10 cm (2–4 in) away from the trunk to prevent rot. Straw, wood chips, or composted bark work well to retain moisture and suppress weeds.
