Tomato Blight

Posted: 29/08/2014 at 23:23

GH toms are certainly not immune from blight but it is less likely.  Good ventilation is a must though as there are other fungal diseases (such as the various leaf spots) which are rarely seen outside but love the hot humid conditions which can occur.  Since fitting home-made solar-powered fans to my GH I have had no trouble with diseases and I reckon a louvre at one end, and 2 roof vents is ideal, as well as leaving the door open for the whole of the summer to ensure a good airflow through the plants.

When I first got a greenhouse I installed a misting system and closed the door and vents every night only to end up with my plants getting every disease I have ever heard of (plus a few more!)  I honestly thought at the time I was providing perfect growing conditions;  I was, but perfect only for diseases and pests, not tomato plants!  Tomatoes do not like humid conditions, rather the opposite in fact.

Bell Pepper Issue

Posted: 29/08/2014 at 18:56

I've successfully kept both peppers and chilies over the winter in a cool room.  It's important that they don't get below 5C or they will pop their clogs.  Not all of them usually survive though.  On a holiday in the South of France many years ago I saw a chilli plant growing by the front door of a small chateau - it was apparently nearly 10 years old and huge - a good 8 feet tall, 3 feet wide and smothered in fruit!

What do i have please?

They look like begonias which grown from corms.  They aren't hardy but if you keep removing the dead flowers and bring them indoors after the leaves die but before the  winter frosts, they should survive and come again next year.  Once the leaves die, don't water them at all and re-pot the corms into fresh compost next spring.  You can put them anywhere frost-free (eg a shed or garage) over the winter as they won't need any light until they start growing next year.  Some folk remove the corms from the pots and store them dry over winter.

Hi Rosemary, no and no.

Don't compost the blighted tomato plants though, either burn them or dispose with the household waste.  It might be wise to grow your tomatoes in another area next year but that is normal crop rotation which helps prevent all sorts of diseases building up.  Blight is caused by airborne fungal spores which are everywhere.  To reduce the chances of infection, only water at the roots as it is when spores settle on wet leaves that the infection takes hold.  That is why plants grown under cover (eg a greenhouse) are less likely to get blight as there's no rain to fall on the leaves.

Apple Trees - Hopeless Cases?

Posted: 28/08/2014 at 18:53

Hi sjb, just to correct a mistake in my post above - I meant to say a high potash feed rather than phosphate.  Potash encourages flower and fruit formation while phosphate encourages root growth.  Both are essential (together with nitrate) but lack of potash (the K in NPK ratios shown on plant food) can hinder the formation of blossom.  Sulphate of potash together with FBB (an excellent balanced food) would be ideal.

If there's not even any blossom, try a feed of super phosphate in early Spring.  If that doesn't spur them into flowering (pun intended!) then not much will!

what is this?

Forget-me-nots.  You could call them a weed but they are easy to pull-up.  I leave mine until the summer then yank them out.

They do well in planters.  This taken in early March this year:

How many will come up again next year is a good question though!

I think I'll order another mixture and plant them anyway - can't have too many but if only a few of the ones I planted last autumn reappear it'll be a disappointment and also be too late to do anything about it.
