Tasks
- Use Bacillus thuringiensis (Bt) to control petunia bud worms and tomato horn worms.
- Watch for pests and treat if necessary.
- Be sure lawns are getting enough water.
- Consider moving a plant if it does not thrive where it is planted.
Pruning
- Prune apricot, oleander and olive trees at least six weeks before the onset of fall rains to minimize fungus infection of pruning wounds.
Fertilizing

Planting
- Resist the temptation to plant more plants in the garden, as they are not likely to survive the summer heat.
- A few winter vegetables may be planted from seed this month. Consult the California Garden Web for more information.
