I live in The IE, zone 9B, and Kelloggs Breakfast tomatoes do really well for me here. All of the warm season veggies I grow in full sun, I put up sun clothe over the top of the beds, once it starts staying in the 90's F.

Last year I planted cherry tomatoes from seedlings in January. I saved some seeds. When and how should I plant the seeds to develop seedlings for the coming year and how do I plant the seeds?

Plant in a fine potting mix or similar soil (light and free draining) or a mixture of soil and potting mix about 1/4

Plants are growing great but not too many tomatoes are setting. Any ideas? it has been a 100 degrees (37C) almost every day. I water every day with drip about 1 1/2 gallons per plant thank you

Hi Lonnie, Tomatoes really don't set fruit above 85 degrees or so. If you keep it going though it should start to produce for you this fall.

Can you recommend some determined tomato that can be grown in zone 9. Thanks.

Hello, i read that i can plant tomatoes until the end of mai but most people say that i need to transplant my tomatoes until march. I bought 8 tomatoe plants (1 determined, 3 cherry tomatoes, 4 beefstake or normal sized tomatoes) will the produce any tomatoes? And if not should i try to keep them alive for the fall season (by putting them in the shade or my garage or inside my home)?

Josef, Tomatoes in 9a or 9b can almost be grown every month, but tomatoes die if there is a frost, and stop growing/producing if the temperature is above 95F. Since this the beginning of summer, it is not advisable to plant tomatoes until after the heat of summer. If you have young tomatoes planted try and shade them, or keep them healthy so they can resume growing after the summer heat has passed.

My tomato plants are ready to go into raised bed. But the temperature drops to mid 40s at night. Is it okay to plant them out yet. Thanks

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
