Tomato plants in greenhouse

Posted: 27/07/2013 at 10:27

You usually end up with impenetrable clumps of foliage when you get branches crossing over each other and lying on each other. It's easiest just to cut off any branches that are crossing. The plants needs foliage for photosynthesis but will cope perfectly well with a lot less foliage than they produce.

Why won't my tomatoes ripen?

When they are ready to ripen, they will do so without this attempt to force them to do something which they are not ready for.

I think your problem is that your Toms as yet are too immature (small) and too early to ripen. Keep feeding them according to the instructions on the Tomato fertiliser every 4 days.

I agree generally. The toms in the photo look don't look close to maturity. And temperature is the key to ripening. Optimum temps are low-20sC and above.

One thing, though. Cut back on the fertilising. The closer to maturity the fruit gets, the less nutrition they take from the plant. During ripening, they actually take virtually no nutrition from the plant.

Yep, it never hurts to give pollination a helping hand with toms and chillies. Outdoors, insects and even a breeze will agitate the flower's internal mechanism and trigger pollination. A brush with the hand or a flick with the fingers achieves the same thing. Indoors, away from insects and a breeze, it's an even better idea.

Ah, Laurel & Hardy come to the forum!

LL, Dove's right about the temperature ripening the toms, but it's a good idea, too, to thin out some of the foliage if it's forming thick clumps. Air circulation is a good aid against fungal problems and clumps of leaves stifle air circulation.

Tomsk, the flowers wither and fall off if they haven't been pollinated. It's common. Not all flowers produce tomatoes.

kati, are they in the ground? And getting plenty of sun? Jasmine respond well to a feed with a fertiliser high in potassium. Tomato fertiliser works well.

Valerie, ripening (or maturity) is down to a couple of things. First, the variety. Some varieties mature earlier than others. Second, once the fruit is at the stage where it's ready to ripen, it's down to temperature alone. Toms don't need direct sunlight to ripen. Optimum temps for ripening are low-20sC+.

How often are you feeding them? Overfeeding can play tricks on the plant's system and delay ripening.

Harvesting Seeds

Saving seeds from F1 plants gives you F2 seeds. F2 seeds won't produce true to the F1 parent plants because, in simple terms, you're starting to unravel the gene combinations created and stabilised in the breeding of the F1 plant.

F2 seeds will usually produce fruit recognisably similar to the F1 fruit but with variations. The further you go down this road - F3 seeds, etc - the greater the variations you'll see.

I know some tomato growers with too much time on their hands who delight in trying to grow out F1 tomato plants to try to determine the original varieties used in the F1 creation. Most seed companies who create F1 varieties decline to reveal the varieties they use.

The more varieties used in the creation of the F1 plant, the longer it takes to trace its origins. I know one chap who spent 10 years on one plant. As I say, too much time on his hands.

Any other symptoms, Anthony? How does the foliage look?

On a seriously warm day, any sort of ventilation will struggle to keep the temps down inside.
