When your granular lemon tree may benefit from feeding

  • When your lemon tree starts a new growth flush of leaves after winter or after moving outside into warmer conditions
  • When your potted Meyer or other lemon tree is actively growing and its limited soil has been supporting repeated watering
  • When your tree is producing new flower buds and foliage, provided its light and watering needs are already being met
  • When a soil or leaf test shows your in-ground lemon tree needs additional nutrients during the growing season

Granules cannot correct cold injury, poor drainage, or blossom drop caused by temperature changes; avoid applying more than the label recommends.

How to care for lemon trees

Light

Lemon trees want eight or more hours of direct sun. Indoors, give them the brightest south facing window, and move potted trees outdoors once nights stay above 50F.

Water

Water deeply until it runs from the drainage holes, then let the top two inches dry. Uneven watering during fruit set makes flowers and small lemons drop.

Soil

Fast draining, slightly acidic soil around pH 6.0 to 7.0. Use a citrus or cactus mix in pots, and keep mulch a few inches back from the trunk.

Temperature

Lemons grow best between 55 and 85F. Meyer lemons shrug off a light frost, but most lemons are damaged near 30F, so move pots inside before the first hard freeze.

Pruning

Prune in late winter to open the canopy and remove dead, crossing or inward growing branches. Rub off any suckers below the graft union as soon as you see them.

Feeding

Scatter Granular Lemon Tree Fertilizer over the soil out to the edge of the canopy and water it in, feeding in early spring, again in early summer, and once more in late summer.
