  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 61°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 24 inches apart
  • Harvest in 8-17 weeks.

There is nothing like the taste of a freshly picked tomato, warm from the sunshine. In the smallest of gardens or even an apartment with a window-box, it is worth growing at least one tomato plant for the pleasure it will give you. They will grow in pots, troughs or even hanging baskets.

Tomatoes should be grown in shelter or under cover in cool climates.

Tomatoes like lots of food! In a garden bed, compost and mulching will produce a crop from one or two plants. In containers, use some suitable long term fertiliser pellets or feed regularly when you water. Feeding improves the flavour of the fruit.

When you plant out, put the seedlings in a deep holes, up to the top set of leaves. The covered stems will put out extra roots and you will have a stronger, healthier plant.

There are many different varieties of tomatoes but they all have one of two growth habits.

Determinate:

Compact bush growth, stops at a specific height and useful for containers. If left without supporting stakes, they will form a dense carpet which excludes weeds and keeps the soil cool and damp.

Indeterminate:###

Will continue growing a main stem, or vine until stopped by frost. The majority of heirloom tomatoes are indeterminate.

Both types need stakes to give them some support otherwise they will sprawl across the garden.

Varieties include Acid-free, Bush, Tall, Cherry, Yellow and many others.

Culinary hints - cooking and eating Tomato

Use in sauces, with fried meals, in sandwiches. Can be frozen whole or in pieces.

Tomatoes being attacked by caterpillars picked one with a hole cut it in half and a caterpillar came out. They seem to be attacking before fruit has ripened. Will I need something stronger than pyrenthrium. Thanks

I've been growing tomatoes in the subtropics for years, the best insect/caterpillar repellents are barriers, which means bagging the fruit. Online sellers (don't want to name them here but the biggest one starts with an A), sell various sized drawstring fruit bags in bulk orders (20, 30 etc). These are reusable, I usually give them a soak in hot water at the end of the season to kill any eggs or pathogens, dry them and store them and I get several years out of them. I bag the baby tomatoes when the first tiny fruit forms as the bugs get there quickly. Yes, it is extra work. But it does work and avoids the need for harsh frequent insecticide spraying. The only tip I have about buying these is get the softer fabrics, there are some with a firm fabric that doesn't close well.

Best to grow tomatoes into the winter months. The summer early autumn time has lots of rain which is the breeding time for bugs and insects. After Easter plant seedlings.

Hi everyone, wondering if it is too late to sow tomatoes?

PLANT SEED OR SEEDLINGS. The information is here if you look for it.

I really enjoyed reading your tips on growing tomatoes! I'll try them out in my garden.

I’m planting Plum Lemon Tomatoes. Do I start in trays or sow directly into the container?

We have planted two different tomato transplants in our raised bed. Bed is about 18" deep. Have good soil, topped with compost, then covered with straw. How often should we be watering this time of year? Current daily temps are around 70-75.

If it is hot a good watering 3 times a week - not so hot 2 times a week. Small plants need small waterings more often. The finger test is a good indicator also.

nick, I've read just to stick your finger in about 2 in. and if it's dry, then water. There's also fertilizing to consider. Homestead and Chill is a great website that has articles on Tomato's (deep watering/ shade cloth) and alot more. dan

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
