Fertilizer

Adding slow release fertilizer of any type at planting has not been associated with improved or reduced survival.  It can in fact be harmful to new developing roots. If you must fertilize, milorganite can be applied in the hole when a tree is planted.  After 1-2 months, a granular fertilizer can be applied within the dripline of the tree. Apply amount of fertilizer as per the label.

Trees should be fertilized with any good tree and shrub product.  This should be done four times per year – March, June, August, and November.

Remember, native plants (once established) can normally survive without adding fertilizer, however other non-native plants require additional fertilizer.

Palms need fertilizing four to six times per year with a good palm fertilizer containing magnesium, manganese, and a full spectrum of other minor elements.  Spread the fertilizer within the dripline of the palm, but not directly against the base of the trunk.

Watering – See the watering guide here.

Fertilization – See above fertilization for palms.

Fungicides – Rootsoak with Bayleton as per label as needed.

Insecticides – Treat bud for borer beetles and palm weevils at planting, in 2 weeks, and again at 4 weeks with malathion and oil.

Herbicides – Do not apply herbicides (such as round up, weed-n-feed) anywhere near the base of these palms. Hand weeding only.

Trimming – We recommend that fruit stalks be removed when first formed so that nutrients are available for new frond development.  Older fronds should be removed when they naturally turn brown. Be sure to sterilize pruning tools with bleach or alcohol solution before trimming to prevent the spread of disease.
