Tomato Problems: Fix Issues Affecting Your Tomatoes

November 6, 2019

[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,
and how you got around them. We’d also love you to subscribe for more
handy how-to videos so you can really get the most from your growing. I’ll catch you next time. [Music]

    Great video.
    First time planting tomatoes and so far none of these problems. Phew!

    I'd love to see you making a video on spring greens (what the Americans call collard greens).
    Most videos on the web are with the US climate in mind so would love to see one for the UK conditions.

    Just battled the ugly horn worm. Within a few day, they nearly decimated my 36 plants. After manually killing over 100 in 2 days, I resorted to Permetherine. Not a worm found in a week.

    To prevent blossom end rot, i put pieces of egg shells in the tomato planting hole. It seems that this problem is caused by lack of calcium in the soil.

    I am having a problem with large holes on my healthy  tomatoes.  I suddenly realized it may be slug.  Is that possible. Is DE a good killer?  This is my first year at this location I never had lugs before.  Thank you.  I get all your video emailed to me.  They are wonderful.

    I am a 74-year-old blind, arthritic gardener. Gardening is joy because it is tactual, I can grow organic, and its tastes SO good. I start seeds inside of my  converted hen house home under lights. I use raised beds (4X4X12 deep on 3 deep concrete blocks. One for the cool plants – variety of lettuce and romaine, 2 types of curly kale, 2 types of chard, bok choi, lots of  broccoli. Use string squares markers and row cover. On the farm, keep this on all season because of wind. Add stronger bird netting/shade cloth to help with Nebraska temperatures and hail protection. Just transplanted fall seedlings. Cucumbers, bush and pole beans, baby acorn squash, 2 kinds of peas, 3 kinds of eggplant, 2 kinds of bell peppers, lots of herbs for me and for the 15 chickens. Inverted daughter's empty 18" deep black plastic  "molasses bins for cattle and filled with mix for full-sized acorn squash and 4 bins of  Beauregaard sweet potatoes. Thought the potatoes were not going to do anything but now at least the greens are growing like topsy. I'm really curious. Love red raspberries and (in an old cattle feeder) to kinds of strawberries — sun-warmed, fresh from the plant to my tongue. Not so many beans reach my kitchen as my service dog and I take turns receiving the fresh-picked bounty. Life is good.

    I fix my tomato rot problrms by every other week, spraying them with an Epson Salt solution. I use a Dollar Store Sprayer, fill it water from my rain Barrel, then add 3 to 4 TBSP of Epson Salt. Then I spray it on the leaves and stocks of the plant, both tomato and Peppers.. I also when I Plant the Tomatos, I wil dump a TBSP of Epsom Salts into the whole first, then I also dump some Epsom Salts around the base of the plants.

  • Reply Kate Wilson August 12, 2017 at 4:07 pm

    I am finding that on several of my tomatoes, the top cracks (where it is attached to the plant). It's really only the top that cracks, and it doesn't negatively affect the taste of the tomato. However, because the top is split, they don't look very nice on my countertop, the fruit is open to gnats, etc., and I must cut out the split top, which ends up taking a good hunk of the fruit away. I have encountered the other tomato issues presented in this video, and have used information from these videos and website to fix them – thanks! Does anyone have any ideas on this cracked/split top?

  • Reply LaBrenda Henry August 12, 2017 at 6:31 pm

    The home garden is the best. Have cucumbers, zucchini, bell peppers, sweet banana peppers( first time growing these. They are better then the bell peppers to me). Yellow squash is great, cut it in 1 inch slices then cross cut in 4. Sprinkled garlic salt, bacon bits, parmesan cheese and butter. cooked it in the oven 20 min. or so, over cooked it is mushy. Test test the squash to what you like. Like it to be soft but have a little firm to the crust.

    I'm not sure whether this would be considered an organic remedy for those trying to grow organically, but I understand that crushing up antacid tablets such as Tums, sprinkling that around tomatoes, and watering it in can quickly make calcium available to tomatoes suffering from a deficiency.

  • Reply Justine M September 9, 2017 at 4:24 am

    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!
