How to Prune Greenhouse Tomatoes

[@ScottHead]

Your Edox tomato grows exceptionally well for me outdoors in zone 9a on the Texas coast. Humidity and lots of heat, but they just keep on producing even well into the summer. I prune to a single vine like you demonstrated, but last year I didn't get to it and let them sprawl and they still produced tons of delicious tomatoes. Great variety, glad you guys brought it to market.

good video. I usually pick all my green tomatoes just before the first fall freeze. I make pickled green tomatoes which is a big selling the next springs farmers market.

Ive just started getting into commercial tomato growing for market. How many stems is recommended ive always just prunned the suckers off

[@JohnnysSeeds]

We recommend pruning to 1 or 2 leaders, though cherry and grape tomatoes can have as many as 4 leaders per plant!

[@dskrpncs]

when using those twine rollers do you stake them at the base or just clip onto the plant under the lowest branch?

[@livelife8900]

Hi, after you cut the top off... 1. Do you still need to take sucker off normally? 2. It will still produce more fruit after the existed one been harvest? Or let just 1 sucker grow to replace the old one? Thank you so much.

Great video. What is your method for pollinating tomato plants in a greenhouse? I am new to greenhouse gardening. Last year I grew three tomato plants and had to throw them all away because they produced no fruit. For the second batch, I pollinated by hand with an electric toothbrush. You have so many plants in your greenhouse that that seems unmanageable. Wondering how you do it. Thank you!

In a commercial greenhouse they use bumble bees in portable hives

Hi.great video.do you leave one or two steam to grow like main plants?

[@JohnnysSeeds]

This is a matter of grower preference. Some growers prune to one leader to save space in the greenhouse. However, having two leaders instead of one can serve as insurance in case anything should happen to the main stem. recommend our tech sheet: Greenhouse Tomato Trellising and Pruning Recommendations demandware.edgesuite.net/bbbw_prd/on/demandware.static/-/Library-Sites-JSSSharedLibrary/default/dw063ce7d1/assets/information/tomatoes-greenhouse-pruning-string-trellis-instructions.pdf

Hi, love the video. Great information, thanks you. Tried the link but it pulls up an error page. I would really like to read the information you refer to. Is there another working link?

I live in Virginia and i want to built a green house but i am wondering how to keep it warm during winter?

1)Insulate with bubble wrap - A layer of bubble wrap clipped to the inside of your greenhouse frame will reduce heat loss and block icy winter draughts. Even an unheated greenhouse will benefit from a layer of bubble wrap. Buy purpose made horticultural bubble wrap insulation from garden centres as this is toughened and UV stabilised. When buying greenhouse bubble wrap remember that larger bubbles will let in more light. You can also use greenhouse bubble insulation to wrap your outdoor pots, protecting rootballs from freezing weather, and preventing your favourite pots from cracking. 2)Invest in a greenhouse heating system - Electric fan heaters are ideal if you have a mains power supply to your greenhouse. Fan heaters are particularly good for moving the air around the structure which helps to prevent cold spots and reduce the risk of disease. If you don’t have mains power in your greenhouse then a paraffin heater is a better option. 3)Use the thermostat - Save money and energy by only heating greenhouses when necessary. Most electric greenhouse heaters come with a built in thermostat so you can set your greenhouse heater to only come on when the temperatures drop below a certain point. 4)Choose the right temperature - Most plants don’t require tropical conditions so don’t waste energy and money on maintaining higher temperatures than your plants require. You can keep your heated greenhouse frost free with a minimum temperature of 2C (36F). Most tender plants such as pelargoniums, half hardy Fuchsias and citrus trees will be happy with a minimum temperature of 7C (45F). This is also a good temperature if you are protecting young plants and plug plants while growing them on. For really delicate species such as Sundaville and other conservatory plants you can increase the temperature to a minimum of 13C (55F). 5)Use a thermometer - Invest in a good thermometer with maximum and minimum readings, and check it daily. By keeping an eye on the air temperature you will be able to use your greenhouse heater more efficiently and adjust it when necessary. 6)Position heaters carefully - Electric fan heaters are best sited in an open, central spot at one end of the greenhouse. Always avoid positions where the heater is likely to come into contact with water. If necessary you may need to angle the greenhouse heater slightly to direct the airflow above plants that are stood close by. This will prevent their foliage being desiccated by the flow of warm air. 7)Only heat the area that you need to - Heating a large greenhouse can be expensive and wasteful if you only have a few delicate plants. Group them together and erect a solid perspex partition or create curtains of bubble wrap insulation to divide the greenhouse into smaller areas which can be heated more economically. 8)Use horticultural fleece - On extra cold nights a layer or two of horticultural fleece will provide several degrees more protection to your plants without the need to turn up the thermostat. Crops in greenhouse border soil can be protected by a handy fleece cloche. Remember to remove fleece during the day to ensure that plants receive adequate light and ventilation. 9)Don’t forget to ventilate - One drawback of heating your greenhouse is the problem of increased humidity. Good ventilation is essential to prevent the spread fungal of diseases and maintain a healthy growing environment. You can prevent moisture from building up by watering plants sparingly, and early in the day. Clear condensation by opening greenhouse vents on warm sunny mornings. Close them again before the sun goes down to trap the daytime warmth in the greenhouse and keep it warmer for longer. 9)Heated propagation - Invest in a heated propagator to help your seeds germinate. If you only make a few sowings then a windowsill propagator may be sufficient. Heated propagation mats are also useful for rooting cuttings and keeping your seedlings warm after germination. Turn your greenhouse staging into a handy heated bench.

@@JohnnysSeeds dont forget about rocket mass heaters, where you bury the piping below the surface and when you run the rocket stove mass heater, you heat the ground, not the air , allowing you to fire once a day a small amount of kindling or wood making it very efficient and cost effective ....google them

[@jerricroft937]

Andrew, were those grafted Tomatoes? Thanks

[@JohnnysSeeds]

Hi Jerri, some years in the greenhouse one row might be grafted and the next might not be. The video aims to describe pruning in general, however, so the methods should apply either way.
