Garden helper wanted (palo alto)

We want someone to help maintain our garden.
Tasks include raking, sweeping, mowing, weeding, and pruning dead flower heads.
Ability to dig holes to plant shrubs, to spread mulch, or to trim hedges on a ladder would all be valued but are not required.
We can provide direction about what needs to be done.
6 hours per week is the minimum commitment.
For a good worker, up to 24 hours per week is possible.
