Tomato Problems: Fix Issues Affecting Your Tomatoes

[Music] Homegrown tomatoes are something else –
beautiful rich fruits with the most divine aroma! But growing tomatoes successfully
depends on avoiding some of the common pitfalls that can trip you up
along the way. Knowing exactly what to expect and what to do about it will greatly improve your chances
of a terrific crop of tomatoes. In this video, we’ll look at how to troubleshoot
some of the most common tomato problems. Aphids and whiteflies are regular
visitors from early summer. They often congregate in large numbers, sucking sap from your plants and leaving their sticky excrement or ‘honeydew’ on the
foliage. Some types also transmit plant diseases. Small infestations can simply
be blasted off with a jet of water, or try spraying plants with a solution of
soapy water, taking care to reach leaf undersides. To minimize potential problems,
attract pest predators such as ladybugs and hoverflies by planting flowers close by –
marigolds are a great choice. You can even buy these predators ready to introduce
into enclosed environments such as a greenhouse. Warm dry, conditions
are perfect for spider mites which, like aphids and whitefly,
can quickly weaken plants. Look out for their faint webbing. Peer closer and you may be able to see
the tiny, usually red, mites. Spider mites love drought-stressed
plants, so don’t let your tomatoes dry out. If spider mites do attack, spray the
foliage with a fine mist of water, insuring you reach all parts of the
plant, then cover the plant with a row cover for a few days to create the shady,
humid conditions that repel the mites. Many parts of North America are prone to
tomato hornworm, a caterpillar that chews holes into tomatoes. Check plants regularly for any signs of damage,
and remove and destroy any caterpillars you find. Cocoons like this are great news. They belong to braconid wasps, which
feed on hornworms to bring them under control. Late blight strikes during spells of
warm, wet weather. Foliage, and then the fruits, become covered in brown blotches. Eventually the plant simply wilts and collapses. Late blight also affects potatoes,
which are related to tomatoes. Blight is rare on indoor tomatoes, so grow plants under cover
if it’s been a problem in the past. Keep the foliage dry by watering at
the base of plants, and remove and destroy any infected plants
as soon as you spot the first signs of blight. You can also grow varieties
described as blight resistant. Blossom end rot is a disease caused by dry
conditions at the root zone and a shortage of calcium. Fruits form sunken black patches
at the blossom end of the fruit. Insure your tomatoes have enough
water at all times, and feed them regularly with a liquid tomato
fertilizer. This is the best way to guarantee your plants are getting
all of the minerals and nutrients they need for healthy growth. Pay particular attention to plants in confined spaces
such as pots or growing bags. Irregular watering often leads to split fruits,
when a sudden rush of water causes the fruits to swell quicker than the skin surrounding them. Instead of leaving soil to completely dry out
between each watering, aim for consistent soil moisture. Water regularly, and mulch tomatoes with plenty of
organic matter to keep roots cool and moist. Mineral deficiencies usually show up in the
leaves first. Magnesium deficiency such as this is the most common form, and often arises as a result of
high potassium levels. To correct the deficiency,
spray a solution of epsom salts directly onto the foliage then switch to a tomato feed
that contains a high proportion of magnesium. Plants can wilt when the soil is either too wet or too dry. Too wet and the roots literally
drown, while very dry soil won’t supply plants with all the moisture they need. Pay close attention to watering. Containers of tomatoes should have good-sized
drainage holes at the base so that excess water can drain out. Raise containers up onto pot feet
if water doesn’t drain away easily. In all cases,
water generously when it’s dry or set up an irrigation system if you can’t
be there to water. Later on in the season, mature plants with lots of foliage
may need watering twice a day. [Music] Poor fruit set – when flowers fail to
produce fruits – is a very common problem. A lack of bees, excess heat, very dry or
humid air, and poor nutrition are all possible causes. Make sure pollinating insects such as bees
can reach plants growing in greenhouses and tunnels. Improve pollination by simply twanging or tapping
on supports to dislodge the pollen, or gently twiddle the flowers between your
fingers. Provide as much ventilation as possible in hot weather. If your climate’s also very dry,
raise the humidity around plants with regular watering and make sure to feed your plants regularly
with either an off-the-shelf tomato feed or a homemade high-potassium liquid fertilizer
such as comfrey tea. Don’t be put off
by all these potential problems. So long as you know what you’re looking
at, and react quickly, your tomatoes are very likely to recover. Now, please do let us know about any other
tomato problems you’ve experienced in the comments section below,

  1. I'm in the PNW (dappled sunlight!) and have individual tomatoes outdoors in 14-16" diameter containers. Last week I moved the containers to the sunniest spot on my property to give them more space. Powdery mildew and late blight are present in the lower leaves of some and I've cut them off to remove the disease but also to allow even more sunlight to reach the green fruit (is this practice okay in September?!). When you refer to "regular feeding" what does that exactly mean? Add fertilizer with each watering? If so, adjust to half strength? What are the organic (i.e. liquid kelp?) and NPK (20-20-20?) options I should consider? There are a few questions in there – thanks for your help. I really do adore your videos!

  2. I have one large tomato plant, it gets the flowers but no tomato grows. The flowers fall off a slight touch. I put manure and potting soil, changed pots too, did not help. Any suggestions? Thank you

  3. The excessive rain killed me this year on the beefsteaks and whites, but the roma tom's did great. I have found that milk is a great way to fight rot bottom.

  4. I have a problem, hope u can help. My tomatoe leafs are turning upside down . How can I turn it back to normal

  6. I have approx 15 tomato plants in two beds in a 14' by 20' polytunnel. I watch out for Tomato fruit worm and eliminate blossom end rotted fruits but I have several fruits with stem end rot, brownish patches where the stem attaches, how do I handle that?

  7. My tomato plant has produced very little fruit this season and the top seems healthy and green, slowly producing a few tomatoes, but the lower half is yellowing and some deadening. It's a patio cherry tomato plant, growing in a pot. I use good soil. Please help!

  8. Hi, new subbie all the way from Trinidad and Tobago in the West Indies!! Very informative video! I found out just yesterday that we have leaf miners on the tomatoes and started treating with neem oil. Please advise.

  9. Wow such a great video! I grew tomatoes last year and ran into multiple problems you discussed. This year I look forward to harvesting more tomatoes and ending blossom end rot! We shall see. Thank you for sharing your knowledge!

  10. This happened last summer, and it was the first time I'd seen it: my tomato plant leaves began to curl DOWN. Does anyone have an idea what could cause this? The same plants had lots of blossoms, but low fruit set.

  11. My plant after digging become died i didnt touch it or its root it was 11cm long
    After how much time i should separate new plants from clay pot and place each plant into new pots

  12. My tomato plants have in curling leaves on the tops and I’ve noticed white specs on the surface of the soil. Has only affected two plants out of eight. Any solutions please ?

  13. I have very few flowers on my sweet 100s cherry tomato plants.
    They are in new potting soil with commercial cow manure.

  14. tomatoes grow like weeds , not much needed just get good soil from HD use raised bed and liquid soluable fertilizer every 7-10 days and you will have success. all the experts on here crack me up

  15. When walking our local beaches I always pick up the cuttlefish bones – a great source of calcium carbonate. This year I crushed up the bone, added it to water then fed the tomato plants with a weekly dose. Blossom end rot sorted.

  16. Almost all the flowers bloom into fruits. But the fruits don't grow bigger. What could be the reason?

  17. Oh thank God. I just didn't water consistently. I was worried when my first tomatoes had small white scars on the bottom. First time growing these

  18. tks man. its very rare any of these videos have any worth to me. but tks,good job

  19. Thank you for all the awesome info!
    My cherry tomato plants are producing super tiny, almost inedible, fruit. Even very ripe and red, the flavor and texture aren't great.

  20. Helloo i am growing yellow brandywine heirloom, seeing your pots are small? What size are you using? 5 galons or smaller?
