The celestial fig (Ficus carica), also called celeste, is a cold-tolerant fig tree variety that thrives in coastal climates. Celestial produces small to medium figs that have a deep purple to muddy-brown exterior and red interior. They ripen from August to just before the first frost. Hardy to USDA zone 8, celestial fig trees grow 15 to 30 feet in height and have far-reaching, shallow roots.
Grow the celestial fig in an area that receives sun all day.
Give the young fig tree 10 gallons of water three times per week during its first year of growing season. Mature trees should only be irrigated with 20 to 50 gallons of water a week, during periods of drought that last longer than two weeks. Excessive irrigation causes the fruit to split.
Fertilize your celestial fig tree with 1/2 lb. of 10-10-10 with micronutrients. Apply the fertilizer three times during the growing season, in February, April and June, according to package directions. Do not apply fertilizer after August to avoid a flush of new growth that may not harden in time for winter frosts.
Inspect the celestial fig tree for common pests such as mealy bugs and scale. Prune off and destroy any heavily infested parts of the tree.
Check the celestial fig tree for signs of disease. Fig rust is a fungal disease that infects young growth, causing it to drop from the tree. Symptoms include yellow spots on the leaves that gradually turn larger. Agriculturists with the University of Florida Extension suggest spraying new leaves with a 4-4-50 Bordeaux fungicide spray bi-weekly during the growing season.
