Frequently Asked Questions

Tomato End Rot

Why are my tomatoes getting black at the end of the fruit?

Answer

Powdery Mildew

The dwarf crepe myrtle in my backyard has developed a layer of gray dust/fuzz on its new growth. What is it and do I need to do something to rid the tree of it?

Answer

Tree Health in Drought Conditions

My family moved to Woodland in August from the water-abundant South-East where we lived for decades.  California’s physical environment, climate, and tree and plant care are completely new to us.  We want to preserve the many fruit trees (Asian pear, fig, lemon, apple, lime, and pomegranate) currently in our yard and are eager to get started doing the right thing for them. Please advise on what we need to do, and can you also direct us to a certified arborist?

Answer

Removing a Lawn for a More Water-wise Garden

We would like to make our landscape more water-wise and are considering removing our lawn, but it seems like such a huge project, we aren’t sure where to begin. Please help!

Answer

Planning a water-wise garden

We removed our old lawn and are now ready to plant a water-wise garden. In the planting space we have full sun and part shade areas and have a drip system set-up for adding drip lines. Please give us some ideas of what, where and when to plant.

Answer

Raised Vegetable Beds

I plan on using a raised planting bed for my vegetable garden this year, and need advice on what combination of materials I should use to fill it. The bed may be large, possibly up to three feet deep, so please help me with what to use and where to find it.

Answer

Crop Rotation

I've heard that you shouldn't put plants from the same family (such as cucumber and squash or tomato and eggplant) in the same spot year after year. Is there evidence for that, and if so, is it loss of nutrients, plant diseases, pests or something else?

Answer

Companion Planning

What is companion planting and is there any scientific evidence that demonstrates that it is beneficial?
