Now is also a good time to dig up any plants that you want to take with you to your new home. If you intend to remove any landscape plants and haven't already done so, you have an obligation to inform the buyer exactly which plants you plan on digging up. That's only fair, and in many states there are restrictions on removing plants from the landscape.
Clean up water features.
Get rid of any visible algae, remove leaves and clean filters so that the water is crystal clear. After all, a water feature that doesn't look good or function properly can be an instant turnoff.
Take care of any irrigation issues.
If there are any problems with an irrigation system, fix them. Irrigation system repairs can be expensive, and you don't want to lay the cost of those repairs on the buyer. Provide information about your irrigation schedule, especially if you have an automatic system. Include instructions as to how the system operates and recommend the same watering schedule that's worked for you.
Repair faucet leaks.
A leaking faucet suggests that there may be other problems elsewhere in the plumbing, and that can be an instant turn-off to buyers.
