Your tree may need a good deep watering before you leave.  Remember that pines do have a seasonal leaf drop.  Hope this helps.

I live in oceanside..when is a good time to repot and prune fruit trees.....if the roots of a fruit tree that are in a container are also in the ground thru the bottom holes of the container when I prune and repot should I also prune the top of the tree

Repotting can be done most any time, but I would avoid the hottest months of the year.  Pruning ?  Depends on what kind (deciduous or citrus) or if deciduous what variety (apple, pear, peach etc.) Different kinds require different type pruning so that section of the branches destined to produce the next crop will not be cut off.  I assume that you are going to repot into larger containers to accommodate the larger root ball of the trees.  If possible I would cut away the existing container from the root ball and repot into the larger container.  If this is not possible I would trim off the roots that have made their way out of the container.  To achieve balance between the rooting structure and the above ground portion of the tree I would trim a small portion off the top of the tree.

I desparately need to control/eliminate yellow nutsedge from a newly landscaped lawn. Since Sedgehammer is not permitted for sale in the state, what are my effective herbicidal options? Please advise.

The nutlets in nutsedge are virtually impossible to remove. Monterey Lawn and Garden Products sell 'Nutgrass Nihlator' at the better nurseries. This product is formulated to kill the nutlet as well as the top of the plant.

Can you please help me identify a stange plant in my garden? It is exactly like a tomato plant, growing next to my tomatoes but instead of turning red, the fruits turn black. They also don't grow larger than a small berry. Where can i go to find out how to identify this? Thanks Rachael

Rachael,

I suggest you bring a sample of the plant along with the strange fruit in a plastic bag (sealed) to the Master Gardener Office for identification.

If you need directions all 858-694-2869.  We are open Monday though Friday 9am to 3pm.

How far away from a leach field is it safe to plant a vegetable garden?

Posted by Julie Atherton on September 15, 2011

Julie,

While it is tempting to grow fruit and vegetables over a leach field to take advantage to moisture and nutrients, it is not recommended because of the potential health hazards associated with the leach field. While there seems to be some who have done so without ill effects, I believe it is better be safe than sorry and would not plant over a leach field. I have not discovered any statements as to how far from a leach field is safe for planting vegetables. However, most vegetable root systems are not very extensive and I would recommend not less than 4 feet from the leach field unless there is a slope involved where drainage and rain would preclude planting vegetables downhill from the leach field.

Regards,
Malcolm, MG

am looking for advice on controlling the spread of invasive weeds in regards to vehicle (cars, tractors & misc machinary) traffic.

The usual procedure is to pressure wash equipment on site before they are moved, even though that is time consuming and challenging. You might check with CalFire and with US Dept of Defense; I know they both have standards but I don't know the details.
