I belong to a community garden locally, and we seem to disagree on how to raise tomatoes! The tomatoes have mostly not done at all well. They are in raised beds but are watered thoroughly every night. Some of us feel they've failed because of too much water. They are watered low down but drenched! Most of the tomatoes are not formed properly, or never formed at all, they are mishapen, and motley. in other words barely usable. The leaves have browned and shrivelled. They just haven't looked healthy. They haven't been mulched because of the slater problem but have mostly mushroom compost dug in. Can you resolve this issue for us please?

You are over watering by far too much. Depends on the soil and stage of the plants growth. Small plant do not need as much water as older plants. Say 4 plants - small plants would only need a few seconds a day and older plants 30-60 seconds. The soil should be moist not wet wet. Soil wet for a long time goes sour. A good idea is to break the top of the soil after a good down pour of rain etc. Soil needs aeration. If you mulch the soil then water each 2nd or 3rd day.

We often have issues like this in life. Tactful diplomacy is required. Tomatoes need 'consistent' water. this means that if they are continuously wet, rather than damp, they will not do well. l If they are 'wet then dry' they will suffer from Blossom End Rot due to irregular nutrient uptake and if they are too dry they will be slow to develop and often flower while quite small so that the plant can finish its life cycle before it dies. Brown and shrivelled leaves along with blotchy fruit suggests they plants are affected by soil born viruses. Soggy, wet soil will exacerbate this. Moist good draining soil is ideal for optimum growth and yield. Crop rotation and planting virus resistant varieties is also a MUST to control or reduce the effect of soil borne diseases. Slaters are normally only 'decomposers' and would generally only attack plants that are very stressed. Mushroom compost is already 'spent' and while can build up the soil it also increases the salinity. Trust this helps.

I have grown tomatoes this year and there is no problem. Have you tried growing cherry tomatoes, they seem to the hardiest variety. My friend who lives near Gloucester NSW cannot grow tomatoes where she is. I hope this is of some help.
