When should I plant a tomato plant in Zone 10b?
09 Aug 20, Sandra G. (USA - Zone 10b climate)
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.

Will Bush Beefsteak Tomato grow in my zone? Any growing recomendations?

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!

What is the best tomato plant and also bush tomato plant for my Zone 7b?

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.

I live in Miami and my tomato plant (from seed) is about 2-3 feet high now but thin stem, very wiry, all over the place. I have wooden stakes in now, but how long after they reach this height will they have a tomato on it? I planted approx. 10 weeks ago.

Of course there are lots of factors (soil watering etc.), I\ll point out a few you may have issues with. I'm a little concerned about your night time temperatures harming the growth or steady growth of your tomatoes -- in addition Blossom drop will occur in if daytime temperatures are warm but night temps drop below 55 F. (13 C.) -- a condition that can easily occur in a greenhouse in winter. When you look at days to harvest for tomatoes -- they are assuming spring/summer growing -- which means the NUMBER of daylight hours is HIGHER. Your area may drop from 12 hours of daylight in summer to 9 in winter.... that's a big difference. Additionally the INTENSITY of the sun is not as great in winter as it is in summer. This means the plant is not collecting as much light. I would GUESTIMATE you need to at double the DAYS to harvest to account for your growing conditions. If you decide to go forward I would opt for varieties that tend to grow well in colder climates that NATURALLY have less intense sun and shorter days (or install lighting if you don't have it and perhaps some heat). REMEMBER your soil temp needs to stay at about 16c -- so if your pots are on the ground or if you are planting directly into the soil, the cold may creep into the soil from below. There are specific tomato varietals bred for cold hardiness which will tolerate conditions at or below 55 degrees F. (13 C.). The best choices for colder climates are short to mid-season tomatoes. These tomatoes set fruit not only in cooler temps, but also reach maturity in the shortest number of days; around 52-70 days. I would look to some indeterminate cherry or plum size tomatoes (so small tomatoes) with very low days to harvest. I have never grow this tomato -- but -- Originally developed for cool rainy nights, Quedlinburger Frühe Liebe (or as I like to say, QFL) is a German heirloom tomato variety that’s ready for harvest in just 40 days after transplanting (!!!) and keeps producing until killed by a freeze. This makes it quite an amazing all-season plant and a real keeper in the garden if you’re prone to cold snaps. QFL is sweet and flavorful with small, juicy red fruits ==> tomatofest (internet site in the USA) says : Old German potato-leaf variety means "Early love of Qued Linburg". Small spindly vines produce 1 1/2-inch, round, 4-lobed fruit in clusters of 4. These tomatoes have great flavor with good acidity. Developed for cool rainy nights. Prolific even during colder summers. **** you really need to review the conditions in your green house -- day and night time temps, hours of sunlight --and you need to choose your variety wisely -- and even then, this might be difficult -- a lot depends on your greenhouse.
