Welcome to Tomato Growing where you will find help and tips on how to grow tomatoes – especially in containers and grow bags. Cherry varieties are usually among the first to mature and easiest to grow, so I’ve included quite a few of these on the website.
For those who prefer larger fruit, there are plenty of tips on how to grow salad and beefsteak varieties.
A little more difficult to grow than cherry tomatoes, especially in a short season area such as the UK, but good results can be expected with the right growing methods – especially pruning!
When To Sow, Plant and Pick Tomatoes
Sowing tomato seed at the right time for your area, will always improve the chance of success! Here are some tips on how to grow tomatoes from seed.
You can grow your own tomatoes outside in pots & containers (you don’t need a greenhouse or conservatory) and growing cherry tomatoes can be done on a balcony, in a window-box or even inside on a sunny windowsill.
So, if you would like to discover real tomato taste, and be able to eat your own home-grown for up to four months each summer, then I hope you’ll browse these pages and have a go yourself, at tomato growing.
Blight Resistant Tomatoes
Three Blight Resistant Varieties (below) – Worth a try if you suffer from blight regularly!
When To Sow Tomato Seeds
The short answer is around two months before your last frost date.
The seed sowing period in the UK is from the beginning of March to the end of April but it is possible to sow up to the middle of May if you choose an early or vigorous cherry variety.
Buying tomato seedlings at a garden centre a little later in the spring, is also an option. Ordering seedlings online is also an option, however, there is a greater choice of varieties when starting tomatoes from seed and it’s a lot more fun too! More on when to sow tomato seeds.

Easy To Grow Bush Varieties
If you are new to growing tomatoes, it’s a good idea to start with an easy variety to grow.
The following bush/cherry varieties are highly recommended:
- Tumbler F1
- Terenzo F1 (Tumbler Ugrade)
- Tumbling Tom
- Red Alert
- Garden Pearl
Bush types are sometimes called “determinate” and do not need their side shoots pinched out.
Bush varieties grow well in containers and large pots so they can trail over the sides, or in an upside down planter such as a topsy turvy.
Trailing and Tumbler varieties include, Tumbling Tom – Red and Yellew, Tumbler F1 and Hundreds and Thousands to name just a few. These are also great for hanging baskets.
There are two types of bush variety.
The trailing bush types (Tumblers) that do as their name suggests and the upright, compact dwarf bush varieties such as Sweet ‘n’ Neat, Vilma and Balconi Red or Yellow. These will need some support.
Tall, Cordon Indeterminate Varieties
Gardener’s Delight, Moneymaker and Golden Sunrise have been around for many years which is a sign of their reliability.
Gardener’s Delight, a decent size cherry, is highly recommended for flavour and crop yield. Moneymaker is also very reliable but there are a few new varieties that will give it a run for its money! Such as Orkado F1, Nimbus F1 and Tamina.
F1 means that the tomato variety is a hybrid and usually more vigorous than an open pollinated variety.
Among the tall varieties that are easy to grow are:
- Gardener’s Delight
- Golden Sunrise
- Black Cherry
- Sungold F1
- Sweet Aperitif
They are all very dependable. Tall varieties are also called “indeterminate” or “Cordon” because they don’t grow to a specific height and are stopped by pinching out the main stem. Cordon means that the trusses of fruit will grow from one main stem, but it is possible to allow two or three stems to develop from the side shoots or suckers.
Final Container Planting
Most gardeners in the UK grow their tomatoes in containers and it is not surprising given the benefits…
- Containers can be placed anywhere around the garden or patio
- Grow bags, also containers, are great for growing tall tomato varieties both in a greenhouse or up against a fence or wall
- Tall sided containers, such as large pots, are great for tumbling tom varieties because the tomatoes can trail over the sides
- Hanging baskets are the ultimate in visual appearance for trailing tomato varieties
One of the biggest advantages of the container is that it can be filled with fresh potting compost that is disease-free.
The problem with garden soil is that it contains little critters that love to eat your young tomato plants and diseases that will
also cause unseen problems that will reduce your crop!
Tomato Plants Grow Quickly
Some plants are like long distance runners – tomato plants are sprinters … they have a short time in which to produce a lot!
This means that everything has to be right for them to grow quickly without obstacles of poor growing conditions and diseases.
Grow bags can be upgraded and improved by using grow bag pots (see below) that improve the watering and feeding process.
A reservoir system, such as found with the Quadgrow Planter (below), can be used to provide water and nutrients 24/7 – great for holiday watering too!
Containers for Tall Tomato Varieties
Tall, indeterminate varieties are best grown in pots at least 9 inches in diameter or grow bags. Using grow bag pots, also known as ring culture, is a very good way to grow tall varieties as they can be fed and watered through the different rings. Inner ring for feed, outer for water. More about containers for tall varieties.
Removing Side Shoots and Suckers
Side shoots grow out between the main stem and leaf branch (see photo left) and are best removed for the earliest harvest.
Leaving a side shoot to grow on a tall variety will produce an extra stem, more trusses and potentially more tomatoes, but if you live in a short season area such as the UK, the first tomatoes may mature later in the season and you’ll end up making green chutney! Removing side shoots is standard practice on tall varieties – more about removing side shoots.
The secret to feeding tomatoes is “little and often” especially when plants are in fruit. A good way to do this is to give half the recommended dose twice as often when watering. This means that food is available for plants more frequently – more about feeding tomatoes.
How much water to give depends on many different growing circumstances including the size of plants and temperatures to name just two. It’s important that roots receive both water and oxygen so saturated soil for too long will cause problems – more about watering tomatoes.
Growing Tomatoes in Grow Bags
This is one of the most popular and convenient ways to grow tall (indeterminate or cordon) varieties and there are plenty of tips on how to optimise a grow bag to get the best crop of tomatoes – more about growing tall varieties in grow bags.
Other Ways To Water and Feed Tomatoes
The Quadgrow Planter
This is a reservoire system that absorbs water and nutrients through capillary action, up into the pots.
It is very effective and the plants can take in water and nutrients whenever they need them. This helps avoid Blossom End Rot and tomato split as there is always access to moisture containing nutrients.
The Easy2Grow Autopot System
Plants are watered in trays by a valve that produces a wet/dry cycle.
This has all the benefits of the reservoir system but with access to a larger water supply.

Many of the problems associated with growing tomatoes are caused by over-watering and over-feeding. We want to be generous to our plants so they’ll grow quickly, but it’s easy to “kill them with kindness” and slow their growth down in the process!
The best advice is “less is more”, at least until plants begin to flower and fruit – then you can be a little more generous with watering and food – more about tomato problems.
Blossom End Rot and Hot Weather
Blossom End Rot is caused by an interruption to the water supply in the plant’s system owing to the hot weather – sometimes tomato plants can’t absorb water fast enough when it’s very hot.
However, the root cause of BER is calcium deficiency as the fruit is swelling owing to short periods without enough water containing calcium.
Over feeding reduces water intake, so for maximum root absorption, feed tomatoes at half strength every other watering and try to reduce the temperature in the greenhouse by ventilation and covering dark surfaces that will give off heat, with white plastic.
Also, removing the lower leaf branches below the first truss reduces water evaporation from the plants – the fewer leaves a plant has, the less water it loses by evaporation (transpiration).
The Success of Last Season – 2016
In my part of the world, last season was better than average. Those who sowed their seed a little too early struggled because of periods of poor weather in the early spring. However, the new variety Mountain Magic made coping with periods of wet weather, and the onset of blight, much easier.
The popular favourites such as Black Cherry, Sungold and Red Alert produced an excellent crop – and the larger varieties did well in the hands of the experienced growers.Choosing Varieties For Local Conditions
Choosing The Right Varieties for Your Part of the World
Many tomato varieties are best suited to the weather conditions of the countries and regions from which they originally came or areas they were developed to be grown in.
Siberian can cope with lower temperatures because it was developed that way – the name says it all!
Moneymaker is an old English variety that excels in a moderate climate and is very reliable.
Marmande originally came from France and requires the weather of the Southern Mediterranean to reach its full taste.
So if you grow tomatoes outside, choose varieties that will cope well in the weather conditions of your area.
You may also wish to choose a selection of varieties such as a cherry, a medium/salad and a large/beefsteak variety for slicing or the barbecue. Some large tomatoes can be eaten like melons they’re so juicy!
Medium size fruit – are sometimes called salad tomatoes.
Cherry size fruit are great in curries and pastas and enhance the visual look of a salad … not to mention the taste!
Bush varieties are great to grow in large pots and containers and can be positioned almost anywhere around the garden or patio without needing a wall to lean against. The plants themselves can be small or large (as well as the fruit) so a pot on a windowsill or a large container may be required.

Choosing which varieties to grow each season is one of the most enjoyable jobs to do in the Autumn and Winter. You can browse the seed catalogues, or surf online where you will find a huge number of tomato varieties from different seed companies.
Growing Tomatoes Outdoors …
Seed Sowing Time – March to end of April (UK).
You can sow up until the beginning of May if you choose a variety that matures early, or you have a greenhouse.
Even when growing tomatoes outdoors, always germinate seed indoors and in new seed or potting compost. This will get the seeds off to the quickest start without the possibility of disease lurking in old soil – tomato seedlings are very vulnerable at this stage. When To Sow Around The World
When To Sow Tomatoes Around The World
To produce a crop of ripe tomatoes, seeds need to be sown around two months before your last frost date. They can be planted out when the risk of frost has past.
It takes around two to three months from sowing to flowering, and two to three months from flowering to fruiting … depending on the variety.
Therefore, sowing at the beginning of April will produce fruit from the beginning of August – if you grow a quick maturing variety.
Growing Under Cover – Unheated Greenhouse
A greenhouse will enable an earlier start and a later end to the season – a great way to increase your crop and have ripe tomatoes available for longer.
My own preference is to sow indoors and get the seedlings established first, before planting them out in the greenhouse.
The great thing about a greenhouse is that your plants are protected from rain and temperatures remain slightly higher.
Go for the biggest greenhouse you can afford , or have room for, as very small ones can create a lot of condensation – try to let the air circulate.
Some varieties can be sown slightly earlier or later
Cherry bush varieties are ideal for sowing early as they are easier to manage (movable in large pots) because of their size and height. You can also sow as late as May (in the UK) if you choose a variety that is quick to mature such as Red Alert.
