Earth-friendly beneficial nematodes seek out and kill grubs and other soil-inhabiting insects. They come on a sponge (invisible to naked eye) that you soak in water, put in a sprayer and spray your dirt or lawn. They will multiply over time and continue to kill grubs You can buy them online or at your local nursery.

I’m zone 10b as well; I started my tomatoes in early February, the weather here is never too cold, so the worst that can happen is that they “overwinter “ and wake in the springtime. I had volunteer tomatoes come up in OCT & NOV and they just grew slowly in a container until they woke in mid mid March and then grew vigorously in April and they’re still giving fruit. These were cherry and Roma tomatoes. I’ve also been sowing seeds every two weeks with determinant (New York, Purple Russian & beefsteak) tomatoes. I freeze all the overages for winter. So, basically, in 10b in southern Cali you can plant anytime and you’ll be fine.

I am hoping that you will be able to answer this question for me. I have raised beds that I vegetable garden in. Everything I have read over the past 10 years says that 2 inches of compost should be added to the beds yearly which I have done. I fertilize with organic fertilizers. My question is I no longer have room for additional compost in the beds. Should I remove some of the "great" soil from the beds to add additional compost or wait until the compost decomposes to add more( this usually takes about 2 years) Thank you in advance for your help.

If you have been adding 2" of compost every year for a number of years I would think your soil is quite fertile. You could, as you suggest, take some off. I would not add any this year, instead I would give the garden bed a dressing of garden or agricultural lime. The continual adding of compost to the soil is great for building up the soil but if there is a lot of organic matter still breaking down you would be safe to leave it for a season. The addition of lime will reduce the acidity and allow the release of a lot of nutrients currently there. Organic matter over time, while enriching the soil, will increase the acidity (lower the pH) and make nutrients less available. Lime reverses this. All the best.

John (Australia) thanks for your response. That was going to be my course of action. You just confirmed it. Again thank you for your input.

I planted a tumbling Tom from nursery in mid April and it is doing great. If I had to do over I would have bought 5 or 6. I planted about 8 different tomatoe plants with 7 of them indertiminate. So far the best are Lemon Boy. They melt in your mouth!

There is a seed supplier specializing in heirloom in our zone. Southern Exposure Seed Exchange. Even if you don't buy seed the website and catalog are great resources.

More information is needed: for example amount of water... soil conditions. The MOST GENERIC, and probably most correct answer is LACK OF NUTRIENTS. Most people plant their plants (tomato) adding lots of compost and/or manure at the time of planting. The plant grows using the nutrients (some are washed away... maybe trees manage to confiscate some nutrients); but as the soil nutrition drops, the plant, still wanting to grow, starts to take nutrition from its lower leaves so it can grow leaves higher up. That is, it is deciding how to best used it's own self to maximize it chances of success; since it can't source the needed nutrition from the soil What you need to do is: ADD manure or compost or anything else you may have to put nutrition back into the soil. I rinse my coffee pot in the garden, I also try to drain things (like the water from soaking dried beans) into the garden. Manure/compost/nutrition (in any form) needs to be added at planting, middle of the season, and close to the end of the season to give that LAST burst of energy to bring the fruit/vegetables into full form. Don't feel like you need to spend a lot of money; get creative; in Canada we can stop by our local coffee shops and pick up the days used grinds for use in our gardens (free); you can add micro nutrients to your garden by filling a pail with water and adding a layer of rocks (rocks are minerals) stir and use this to water your plants. Left over tea bags, left over coffee grinds, stuff that you might rinse down the sink (food juices), blood from meat when you wash it before cooking it ..... anything like that all puts nutrition back in the soil.
