Question: I started a new lawn last fall, and I am very happy with the results. I want to reseed the areas that came up a bit thin. When and how should I do that so I don’t damage the rest of it?

Rose family needs iron application

Question: What other landscape shrubs benefit from an application of iron chelate? I know bottlebrush and photinia. Others?

Citrus persnickety especially when young

Question: We have a question about our 5 to 6 year old naval orange tree. For the past 2 to 3 years, we left the fruit on the tree until the weather man said freezing temperatures were coming. But with just cold nights, the fruit seems to dry out. Can we pick the fruit early and let the oranges ripen in the house?

Coir matting normal in some palms

Question: I have “burlap” growing between the fronds at the trunk of my 4-year-old male date palm. They look awful and are difficult to manage. Please advise.

Shape ash trees early on or face pruning pickle

Question: We have two fan Texas Ash trees that are 15 years old. They are spreading out too far. How far can we cut them back without killing them?

Bolster fig yield with a second tree

Question: I have a large fig tree that gives me small green figs, and that is all I get. I think the problem is not enough water, as you said. I also saw the picture of cuttings to grow another tree. Can I do that, or should I buy a second tree? What about pruning? Is this a good time?

Bird’s nest mushrooms benefit soil

I found some mystery pods in the garden when doing some clean up. One of the pods is closed, and the second is open and with what appears to be small black seeds. Any idea what this is?

Bean stalks bend in the cold due to stem rot
