🫘 Clifford Carob

What it looks like

Why this variety

Carob has a pollination problem that stops most gardeners before they start: the species is typically dioecious, with male and female flowers on separate trees, so a seedling tree may turn out to be a male that never fruits, or a female with no male nearby. Clifford sidesteps the whole puzzle. It is a self-pollinating hermaphrodite variety — one tree, no partner required — and it produces a large crop of good-quality pods with excellent flavor. That single trait turns carob from a gamble into a plan.

The pods are the point: long, dark brown, naturally sweet, dried and ground into carob powder and syrup — chocolate’s patient, drought-proof, caffeine-free cousin. Clifford’s pods are of good quality for that use, and the tree itself is a handsome, long-lived evergreen with dense, glossy foliage. It is a shade tree that pays rent in pods, provided you live where it is happy.

Self-fertile hermaphrodite — no male/female pairing needed. Large crops with irrigation; excellent flavor. Pods used as carob powder and syrup.

How to grow

Plant in full sun in deeply drained soil and water young trees until established; mature carob is famously drought-tolerant, but ‘drought-tolerant’ describes an established tree, not a transplant. Prune lightly for structure — carob’s dense canopy needs airflow in humid climates more than it does in dry ones.

Plant grafted trees in full sun in deep, fertile, well-drained soil, and give them their mature spacing from day one — nut trees become large trees, and crowding a nut tree is a decades-long mistake. Stake young trees against wind, prune for a strong central leader or open form depending on species, and be patient: nut trees are measured in years to first crop and decades to peak production.

Florida framing, stated plainly: carob is a warm-climate tree, and Clifford’s Florida case is South Florida only, where frost is rare — and even there it is a trial, not a sure thing. Carob wants heat, excellent drainage, and a dry ripening season; Florida’s humid summers and wet falls are not the Mediterranean dry season it evolved for, and young trees are frost-sensitive, so North and Central Florida cold snaps are a real risk. Plant in South Florida in full sun on high, well-drained ground, give it room — this becomes a large tree — and check local guidance before planting a large, long-lived tree. Do not plant it in North Florida expecting it to survive winters.

Water & feeding

Water young trees deeply and regularly until established; mature nut trees tolerate dry periods but crop best with consistent moisture through nut fill. Mulch heavily with wood chips or leaves, kept off the trunk, and work worm castings into the root zone at planting and as an annual top-dress. Avoid disturbing shallow roots with cultivation — many nut trees resent root disturbance for years.

Common problems

• Squirrels — the primary harvest competitor for every nut tree. Harvest promptly when nuts drop or husks split; leaving nuts on the ground is donating them.
• Blight, canker, and fungal diseases — worst in humid climates. Choose resistant varieties where available, prune for airflow, and remove diseased wood promptly.
• Wet feet — nut trees drown in waterlogged soil. If your site holds water after rain, plant elsewhere or plant on a mound.
• Alternate bearing — a heavy crop one year followed by a light one is normal for many nut trees, not a sign of failure. Thin heavy crops and feed consistently to soften the swing.
• Weevils and husk pests — fallen, wormy nuts should be cleaned up promptly to break pest cycles.

Harvest

Harvest when nuts drop or husks and burrs split — do not pick unopened burrs and hope. Husk or hull promptly, wash if needed, and dry thoroughly before storage; nuts stored damp go rancid or moldy. Wear gloves for spiny burrs and husky walnuts alike: the tree defends its crop, and it is right to do so.

Saving seeds

Clifford is a self-pollinating hermaphrodite carob — one tree, no partner required — but as a named variety it is still kept by grafting, not seed; buy a grafted tree. The Saving seeds section of the Carob guide covers seed for the straight species.
