I have 2 growbags in a polytunnel each with 2 tomato plants. The leaves on one of the plants is wilting. If I'm watering incorrectly surely both plants in this bag should be affected ? What am I doing wrong?

The leaves of my tomato plants are beginning to curl up at the edges.This happened the last couple of years but they always recovered fairly well.Is there some deficiency in the soil.I sow the tomato plants in well manured ground(well rotted horse manure) in the polytunnel.

Recently erected a polytunnell & planted my crop and have now found loads of leatherjacket pests. Can you please tell me how I can treat these without damaging the crop? Your advice would be greatly appreciated.

I have a polytunnell 25' x 14' approx with one entrance door. Plants tend to wilt from the heat on warm days even though the door is left open. Do I need a second opening at the opposite end of the polytunnell for air to circulate or can I do anything else to remedy this problem. Plants are watered every evening after sun down.

Just wondering should my calla lilies have begun to show yet - I planted them outdoors about the 10th March and there is still no sign of them breaking through the soil - what can I do about them? I planted gladiolus at the same time and they are popping up now.

How cantaloupe production in greenhouse?

Had tomato seedlings in plastic 3 tier greenhose for few days. Planned to pot on this weekend. Unfortunately i never took the plastic cover off the propagator and today (wednesday) when i checked them they had wilted badly after fine weather. Some actually had cracked stems. Should i start again or could they recover?

Looking for information on growing tomato plants i.e best time to plant and where.

I saw your reply re woodlice, natures dustmen etc. but last year they certainly ate the roots of my cucumber, I have masses of them again this year in my p.t. I garden organically in the p.t. so dont use pestcides, is there anything I can do to get rid of them? my husband suggested Jeyes Fluid (put in during the winter) but we are too late now to use it, and I am worried that it shouldnt be used in a p.t. anyway. Can you help me please?

Just wondered if you could recommend a supplier for a 8x12 or 6x12 greenhouse. Is there a benefit/disadvantage to polycarbonate vs glass? Best siting for a greenhouse? First thing to do when its erected?

I recently got two fleece cloches in ALDI (the plastic ones were all sold out), in terms of what/how they protect against do the fleece cloches do exactly the same job as plastic or...

I set seeds in trays 3 weeks ago for tomatoes, melons, aubergines, cucumbers & peppers but they are not germinating. I have them in my glasshouse. Any idea what I did wrong?.

My question is regarding the pruning of this shrub. I have a small specimen that has been totally stripped of its leaves over the winter and im wondering can i cut it back to encourage regeneration? Or is it just too tender? Would a light prune encourage it to put on new leaf?
