There is excellent information and videos on the Orchid Web to guide you through repotting your orchid.

For your lawn - last summer was tough because we were in the 3rd year of a drought. This year we are expecting another year of drought. The best time to overseed a lawn is in the fall but the second best time is in early spring - now. 

Now, early May when the temps are still in the 60’s and 70’s is a good time to overseed your lawn. Purchase your seed fresh from a local nursery and purchase only what you will use now. Grass seed doesn’t store long. We recommend a mix that includes fescues as they are good during times of drought. 

When you water - water deep so that your grass grows deep roots. And it is normal for grass to dry out between waterings. Don’t mow too short and don’t fertilize until fall. Water early in the morning.
