Talkback: How to collect and save seeds

Posted: 10/07/2012 at 13:14

can i take the seeds out of a pepper and grow them


Yes, but the peppers they produce will depend on whether the parent fruit is a hybrid or pure variety. If a hybrid, you will end up with a version of the parent fruit. If a pure variety, provided it wasn't cross-pollinated, you will end up with the same fruit.

Tomato leaf problems - help

Well, that's a good basic mix. It shouldn't lack magnesium in any way. Cutting back on the feeding - Tomorite is very high in potassium, which can thwart the take-up of magnesium, as Dove suggested - should be a big help.

Toms outdoors in the ground are less prone to these sorts of nutrient conflicts - though not immune to them - because the roots, in the ground, can effectively find what they need somewhere in the soil around them. Roots in containers are trapped and can only access whatever you give them. On top which there's the problem of nurtients leaching from the mix with every watering.

That said, there's also a leaf mould problem, and that is greenhouse-specific. It's why the outdoor plants are fine. I think you probably ran into a perfect storm of fungus and nutrient deficiency, Gard.

That's why I think the problem has been as much disease as deficiency. Or in fact more disease than deficiency. If it were more deficiency, all the plants in the same compost should suffer the same problem.

Out of interest, could you post that recipe you used for the home-made mix?

ES is usually applied as a foliar spray. The leaves absorb the ES, a faster-acting process than going via the roots, whereby the roots first have to absorb the product before distributing it. Mix up 20g ES/litre of water and spray once a day for a week or 10 days and see how things look.

Does anybody know what causes cuckoo spit as it keeps appearing on my lavender is there a way of getting rid of it

 

Quickest way to get rid of it is either by hand or with a blast from the hose.

It's been a fascinating couple of days, Gard. A good garden mystery is always fun - except when you're on the receiving end!

No, spraying for the deficiency won't hurt. I think it's about 20g ES per litre of water. Spray in the mornings to let the foliage dry out during the day.

Spraying against fungal problems has become a tad controversial these days. Most of the common fungicides are chemicals and many are reluctant to use them and with good reason. They poison foraging insects amongst other things.

The most common organic treatment is a copper sulphate spray. Very popular here in Italy. You see tom plants everywhere with bright blue leaves. But, while it's organic, it's also a metal, it can eventually build up in the soil, and doesn't do foraging insects much good either. I don't use it because I don't like metal building up in the soil.

The very best treatment I ever came across - and used when I was back in Australia - was a chlorothalonil-based spray. It comes under various brand names - Daconil, Bravo, etc. It's synthetic, a chemical, but harmless to foraging insects. It will kill fish if you pour it into a fish pond. So I didn't pour it into any fish ponds. It's very widely used in the US - the home of heirloom tomato growing - and even by many organic growers. They acknowledge that it's not organic, but (a) it doesn't harm the garden wildlife; and (b) it's stunningly effective.

Problem is, it's hard to come by outside the States for domestic use. In fact, in Australia, it was only available in bulk for farm use. So a group of us tomato growers all chipped in, bought a container, and divided it up. It worked brilliantly.

A week or so ago someone posted in this forum about spraying with milk against fungal problems. Some people do, and swear by it, but there's no scientific evidence that it works. At best, it's thought that the milk might amend the pH of the leaf surface to a figure less sympathetic to the spores.

The principle of spraying against fungal problems isn't that you kill the spores. You can't. You spray preventively - before the spores arrive - and coat the leaves (on both sides) efectively stopping the spores getting a grip. Normally you would start spraying just after planting out and about once a week thereafter. If it rains, obviously, you have to respray. It's not always failsafe - though I found the chlorothalonil was - but it's the best you can do in terms of taking positive action.

I don't spray here in Italy but only because I can't get chlorothalonil here. I just do all the basic housework and hope for the best. I get Early Blight and Septoria Leaf Spot - the two most common fungal problems in the home garden, and they're pretty inevitable - but nipping off affected leaves as soon as the symptoms appear keeps things under control.

Gard, a pH of 6 is ideal for toms. They prefer it slightly acid. A homemade mix might well explain some nutrient deficiencies, but I haven't seen those sorts of lesions before as a result of, especially, magnesium deficiency.

In terms of limiting the chances of fungal problems - if you don't want to spray, you just have to adopt all the housekeeping practices mentioned above. And, in a greenhouse, most of all, great ventilation.

You will never escape fungal spores. They're airborne, they're everywhere, and effectively invisible. All you can do is create an environment that gives them the least sympathetic conditions.

 

Courgette 'Parador F1 Hybrid' surprising!

Butternut squash but tiny, no flowers yet (flippin' weather).  Nothing else likely to fertilise them and next door's courgettes aren't flowering yet.  No other veg patches nearby either.

I have two Parador plants in a raised bed, both are behaving exactly the same and each of them have three 11cm courgettes with the flowers still attached, and we ate four the same size a few days ago.  The first male flower has opened today.

Well, something's fertilising them!

Unless, of course, you have a case of - ahem - Virgin Birth.

What else do you have growing nearby?

Tomatoe plants with no flowers !

As Geoff says, avoid the temptation to feed them. In fact, don't feed them at all and keep watering to an absolute minimum. Regardless of the weather, they are more likely to produce flowers - the first step to reproducing themselves - if they think they're struggling for survival.
