每日吃瓜

I have a Chinese Elm which I purchased five months ago from an area Lowe’s. It has done very well until now, as I noticed leaves missing from the top branches.

Since it is so warm ( above 50 degrees overnight) I keep it on the front porch with a Juniper. They both receive adequate sunlight, and I only water them as needed.

I wait until the soil feels dry to water again, and I mist them once a day. Have I done something wrong to the tree in trying to care for it?

?

Do the pot have drainage holes?
