Leaf burn or scorch on Tomato and Cucumber plants

A common but not always a major problem with tomato and cucumber plants is leaf burn or scorch normally on the tips of the leaves. This problem can be cause by too much sun on a dry plant or too strong a concentration of fertilisers. There is a school of thought that wetting leaves in strong sunlight will cause leaf burn. However, after having grown tomatoes commercially in the past for I have never had this happen, In fact we used to put on overhead sprinklers on hot days to cool the plants down and get moisture around the flowers to help with the setting. I even grew tomatoes in plastic tunnels in Portugal with only side ventilation, so we had to put the sprinklers on quite a few times a day or used a hose pipe the workers appreciated being cooled down at the same time. Tomatoes are thirsty plants and need a lot of water on hot days especially. The compost or soil can soon dry out, especially if you are watering only once a day. The best way to water tomatoes plants and cucum

Let your tomato plants do the talking

All plants are great at sign language, it's just a matter of you learning it as well. You can either take action,or just let them do their own thing, depending on the signs that they give out. Let's start with an easy example, leaf curl. This can be a sign of over watering. Tomato plants prefer a little and often when it comes to watering. However, we cannot always do this. If I am going out for the day and know it's going to be really hot, I sometimes give the soil a good soaking, it also adds humidity to the poly tunnel, which is good for tomatoes and helps fruit setting. I do not worry too much about this sign. Another sign of over watering is a discolouration of the leaves, as it shows a lack of nutrients. Pale yellow patches are the first sign. I use a seep hose for most of my watering. But some plants need more water than others depending on how much fruit they have on them, or maybe in a warmer part of the poly tunnel, so it is a job to get even watering, which

Leaf curl on tomatoes

I have had a little leaf curl this week, so I thought I would copy a part of what I posted on it last year, as many of you will have some leaf curl as the weather warms up. Basically your plants have had plenty of water, so the root system has remained fairly small. The plant them cannot take up enough water on hot days, so it curls it's leaves to have less light on them, and it controls the growth of the plant, to concentrate on growing its root system. However, the plant still needs plenty of water at this time of the year, so please do not dramatically decrease watering, unless your plants are going very pale. Like it explains below it is just creating a larger root system to help cope when it is more laydened with fruit. Physiological Leaf Curl in Tomatoes. When tomato plants grow vigorously in mild, spring weather, the top growth often exceeds the root development. When the first few days of warm, dry summer weather hit, the plant 'realises' it has a pr
