Too tall and leafy usually means too much nitrogen (i.e. richness, fertility). See later comments re ash, minerals etc.

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.

In Miami, you'll want to plant your tomatoes in the cooler months.....the typical summer months that you'd think to plant tomatoes are too hot here in Florida....the night time temp needs to get below 80 degrees otherwise they will flower and then the flowers will fall off and not produce any fruit. So our cooler months, although still warm are the best months for tomatoes as well as some other veggies.....like peppers.

Tomatoes usually take 90 days to harvest. Tip: you need good fertilizer and do not water every day; yes it promotes growth, but once the plant is planted and well watered, then you should water only once a week. Of course this depends on your environment. Watering less will trigger the plant to produce more flowers. Plant 2" deeper than normal Use: 1 cup of gypsum in the hole 1 cup of calcium in the hole Your Tomato plant will be happy.

I just wanted to say what a wonderful site this is. As someone who has just discovered the joy of edible gardening (despite many years of my mother trying to convert me!!), it is providing me with the basic and invaluable knowledge to help get me on the right track. I also really enjoy reading the Q&A posts and am picking up a lot of great tips. Thank you xoxo

Liz, what would be the best mulch to apply to the soil under tomato plants and vines? I'm growing them in a raised bed for the first time. The soil is very dark, whether wet or dry and I'd like to keep their roots cool until they can supply their own shade. I'm in Hawkes Bay. Thanks.

In regards to those aphids under the leaves may actually be white fly these tend to scatter when disturbed if so I found that sticky traps yellow in colour work very well they are sold in most hardware and nurseries. Hung around plants with infested bugs you will be amazed how well they work and no need for spray.

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.
