Plant Meyer in a Central Florida yard

The lemon people actually keep in Orlando and Central Florida is usually a Meyer, and Citrus Culture in the Home Landscape (HS132) explains why. It does not recommend the true lemons for home use. It offers Meyer as the substitute, and it counts Meyer among the trees worth having for looks as well as fruit. The grocery Eureka is a different plant.

The true lemon (Eureka & Lisbon types) is not recommended for home use because of its susceptibility to scab. The 'Meyer' lemon is a reasonable substitute for true lemons in home gardens.

Meyer versus Eureka

That is the sentence that decides this page. The home-landscape citrus guide groups lemons and limes as acid fruits and rules the true lemons out for the home landscape on scab susceptibility alone. Its Table 1 lemon row backs it up, listing a July through December season, one to six seeds, and susceptibility to scab, greasy spot, and melanose. Meyer is the recommendation that replaces it, and the home-landscape citrus guide also lists Meyer under dual-purpose fruits alongside kumquats and calamondin, meaning trees that carry real ornamental value along with useful fruit. A Meyer is not a small Eureka. It is rounder, thinner-skinned, and less sharp, which is why a stand selling Meyers is selling a different thing than the grocery box.

Lemon Growing in the Florida Home Landscape (HS402) is the true-lemon paper. It classifies Meyer as a lemon–mandarin hybrid (C. limon × C. reticulata), not a Sicilian true lemon. Eureka came from a Los Angeles seedling in 1858: a non-vigorous, spreading, nearly thornless, cold-sensitive tree that bears fruit in large terminal clusters not protected by foliage. Lisbon is large, vigorous, densely foliated, and thorny, with similar fruit borne inside the canopy. Both are very acid. U.S. commercial lemon acreage is almost all California and Arizona; UF/IFAS citrus timing notes puts Florida at under 600 acres, in south Florida. The pointed grocery lemon in an Orlando bin is that crop, not the round patio tree.

Cold snaps

The home-landscape citrus guide limits citrus to areas that do not regularly experience freezing temperatures, and it tells you to weigh freeze frequency first in historically cold areas: where freezes come every few years, avoid the more cold-tender types and choose only the hardiest. Acid fruits sit on the tender side of that instruction, and a sweet orange is the paper's first choice for a dooryard. If you want a lemon anyway, put it in the warmest, most sheltered part of the lot — south of a wall, out of the north wind.

Look up a specific Orlando address on the 2023 USDA Plant Hardiness Zone Map. Hypothesis: much of the Orlando urban core maps to zone 10a (average annual extreme minimum 30–35°F); inland pockets of Central Florida still include 9b. A zone number is a 30-year average of winter lows, not a forecast. UF/IFAS lemon guidance lists trees defoliated at 22–24°F, severe wood damage at 20°F, flowers and young fruit killed at 29°F, and mature fruit damaged at 28–31°F. After a freeze, Recovering from Freeze Damage (CH004) is wait-and-see. Do not prune until the spring flush is fully expanded and mature. Twigs and branches may keep dying for months. Reduce fertilizer in proportion to canopy lost. UF/IFAS Extension offices repeat the same patience after freeze nights.

The rest of the siting is the same as any citrus. Full sun produces more fruit than light shade. Home spacing is a minimum of 15 feet between trees. UF/IFAS lemon guidance wants 15 to 25 feet from buildings and other trees because lemon is more vigorous than most citrus. Stay away from septic tanks and drain fields, because roots clog drains. Take weeds and sod out from under the canopy and especially off the trunk, since weeds against the bark invite the soil fungus behind foot rot. The home-landscape citrus guide does not recommend mulch around citrus; where a tree sits in a mulched bed, keep the mulch a foot back from the trunk. UF/IFAS lemon guidance allows a 2- to 6-inch mulch ring kept 8 to 12 inches off the trunk. Keep the trunk dry either way.

How to plant

1. Buy a vigorous container-grown tree. The home-landscape citrus guide says those can be planted any month of the year and are more likely to live and thrive.
2. Set it at the same soil line it had in the container. Take some soil off the root mass so the outer roots reach the sand, because a hard edge between potting mix and native soil makes both watering and rooting difficult.
3. Build a basin that holds five to ten gallons. For the first month, run a hose into it ten to fifteen minutes twice a week, or supply eight to ten gallons by hand. After that, water when new growth wilts in mid-afternoon.
4. Start fertilizer when buds swell or three weeks after planting, then about every six weeks from February through October in the first year.

The home-landscape citrus guide calls an 8-8-8 with other macro and micronutrients a good general citrus fertilizer, working up from half a cup at the first application to a pint and a half by September. A bagged citrus food with micronutrients is the retail version. Get this. If a granular bag is not practical, spikes are the other format on the shelf. Get this. Two cautions from the paper are worth more than the choice between them: keep fertilizer off the trunk, and do not measure with a one-pound coffee can, because a can that size holds nearly three pounds.

Ground or pot

The home-landscape citrus guide is a paper about trees in the ground, and it publishes no container recipe for a mature citrus tree. What it publishes instead is the freeze paragraph, and for a tender acid fruit in Central Florida that is the argument for a pot. A tree you can wheel into a garage does not need the forecast to cooperate. Meyer is a common patio tree for exactly this reason. If you go that way, use a container with real drainage and one you can move when the soil is wet and heavy, and do not trust a dwarf claim that is not on the nursery tag. The home-landscape citrus guide also notes that rootstocks change soil adaptation and fruit quality, and that retail trees come on industry standard rootstocks rather than a choice you get to make. Ask anyway. Buy a Florida Budwood certified tree if the nursery has one (HS402).

Hypothesis for Orlando: a 15–25 gallon pot, a plant caddy, and a garage or enclosed porch is the freeze plan that matches the HS132 cold paragraph when you cannot spare a sheltered in-ground site. Potted soil freezes faster than ground. UF/IFAS Putnam County freeze notes flag containers because the water in the pot can freeze and leave roots unable to take up moisture. Move the pot before the night, not after. Water the root ball after a freeze once the soil thaws. A pot still wants full sun and a fertilizer with micronutrients; it dries faster than a yard tree, so the HS132 “wilt in mid-afternoon” rule is the watering cue.

Pests

The home-landscape citrus guide is unbothered about pests in a landscape, and the reasoning is useful. Most citrus can be grown with no chemical pesticides at all. Fruit may carry external blemishes that have no effect on internal quality. Tree appearance may suffer, but the tree is rarely seriously damaged, and many citrus pests are held down by natural biological control. Pest control should be undertaken only as the need becomes evident. When it is, the paper names horticultural oil for insects, mites, and scales, and copper fungicides for most fungal diseases, and it recommends contracting a licensed applicator for spray work rather than improvising.

The larger Florida story is not in the home-landscape citrus guide. UF/IFAS Home Citrus says citrus canker and, more recently, citrus greening have significantly reduced residential enjoyment of these trees, and its two-year Master Gardener project starting June 2022 tested grower tools at homes: individual protective covers, reflective ground cover, red dyed kaolin, and insecticides and fungicides. Buy clean nursery stock and take questions to your county Extension office.

When to pick in Orlando

Citrus ripens on the tree, so the season in Table 1 is the pick window and a lemon that is still green is not ready. The lemon row runs July through December. That row is true lemon. The home-landscape citrus guide does not print a separate Meyer month table. UF/IFAS citrus guidance says true-lemon time from flower to harvest runs 4 to 12 months, that Florida bloom can start in late December and run into March with later blooms possible, and that a tree may hold fruit at different stages at once. A Meyer turns a deeper yellow, almost orange, and gives slightly when it is ready, and fruit will hold on the tree rather than needing to come off all at once.

Hypothesis for Orlando and Central Florida: Meyer often hangs from late fall through winter; pick as you use it; pick the lot before a forecast night in the high 20s. That lines up with the HS402 true-lemon fruit-damage band of 28–31°F. Color alone will fool you if you are waiting for a grocery Eureka. For fruit above reach, a pole with a basket beats shaking the branch. Get this.

Most of a lemon's flavor is in the peel, not the juice. A rasp zester takes the colored layer and leaves the bitter white pith behind. Get this. Zest before you cut, every time, because you cannot zest a squeezed half.

Pruning

Take the shoots that come from the base of the trunk early. Those are the rootstock and will not give you the fruit on the tag. A mature tree does not need canopy pruning for production or health except after substantial freeze or disease injury, and the home-landscape citrus guide warns that unnecessary pruning cuts the crop. Remove vertical water sprouts, which are slow to bear and crowd productive limbs, and make cuts flush so no stub is left for rot organisms.
