How to Grow Every type of Tomato - from Cherry Tomatoes to Beef Tomatoes•
Posted on 14 February 2022
Tomatoes are an easy and rewarding crop to grow. Quite often they are the first plant a child will toddle home from school with and are therefore a perfect introduction to growing your own food. The main reason to grow them though, is flavour. Supermarket tomatoes are grown to travel well and stay looking good for as long as possible on the shelves. As a result, they are often picked before they are ripe too which is not ideal. Flavour is on the list of criteria but much lower down than it should be.
Technical Tomato Terms
First of all, let's start with some technical tomato terms because these will help you choose the right variety for the space you plan to grow them in.
Indeterminate or Cordon varieties
This is your typical, tall tomato plant. They have a single long stem and usually grow up canes or twine up to 6' (1.8m) in height. Cordon varieties produce side shoots which need to be removed, as they appear, or they will grow into large lateral branches leaving a tangled plant with a lower yield of ripe fruit.
Determinate or bush varieties
Cherry tomatoes fall into this category. These are smaller more manageable tomato plants that are great for growing in containers, hanging baskets or anywhere where space is limited.
Bush varieties are sprawling rather than having a single central stem. Because they are low and sprawling they are suitable for growing under cloches or mini polytunnels. They spread about 2 or 3 foot and removing side shoots is not necessary as the bush is ‘self stopping’.
Dwarf plants are the smallest, very compact plants growing no more than 8 inches high. Ideal for container growing.
A truss is a group or cluster of smaller stems where flowers and the subsequent tiny green tomatoes develop. Much of the support and pruning of the plant is done in relation to where the bunches of tomatoes, or 'trusses', are growing so it is useful to know this term.
Where to Grow
Whether they are bush cherry tomatoes or large cordon tomatoes, tomato plants require full sun. This is especially important in most areas of the UK where summers are unpredictable and sunlight can be scarce. Position them against a wall or fence if possible to get the best results. They also need good fertile soil. Prepare your beds by adding plenty of well rotted manure at planting time, as much as a full wheelbarrow every 3 square meters.
If you don't have a large garden or allotment and want to grow in a container or planter then Haxnicks have a selection to choose from. In reality, which container you choose depends on the tomato variety you have selected above. There is a useful table at the bottom of this blog which shows the whole range of planters with a short description and link to find out more.
When & How to Grow
Sow seed indoors in late February to June. Due to the temperature, if sowing early use a heated propagator or a warm, south facing windowsill.
Tomato Seed planting depth
Tomatoes can be sown 3/4" (2cm) deep in compost filled seed trays.
Try and keep your seedlings warm and give them as much light as you can. Too little light will result in tall and weak seedlings. The best tomato seedlings are short and stubby rather than tall and thin. Compost should also be kept moist and should never be allowed to dry out.
When to prick Tomatoes out
When your seedlings have 5 or 6 leaves you will need to prick them out and pot them on into 10" (22cm) pots filled with a rich potting compost. Subsequently, when they are 12" (30cm) tall move them to their final position in your plot or container. To grow really strong plants you can transfer the seedlings from the seed tray into Rootrainers and plant them out after around 6 weeks when they should have developed a super-strong root system.
If you are growing cherry tomatoes or other bush tomatoes then they probably won't need support.
But the larger cordon varieties they will need support as they grow. Canes have long been the traditional way to do this. It is especially important, if using canes, to ensure that the plants are tied gently to allow the stem to grow in both width and height. Tying too tightly will restrict growth and damage the plant. The best way to support them is with a frame such as the new Haxnicks Tomato Crop Booster. Since this will gently support the plants without damaging them. A properly supported plant can put all of its energy into producing fruit leading to higher yields. So if you want to triumph at the village show or simply want to be self sufficient in tomatoes then this could be your secret weapon.
If you have chosen a cordon variety you will need to pinch out side shoots as the plants grow. You will find these shoots between the main stem and the branches. To the novice gardener it seems like this will mean you get less tomatoes but the opposite is actually true. Pinch them out when they are 1" (2.5cm) long and this will add light and air to your plant, keeping it healthy and allowing it to concentrate its energy on fruit production.
When the plants reach the top of the greenhouse or have set seven trusses indoors or four trusses outdoors, remove the growing point of the main stem at two leaves above the top truss.
Watering and Feeding
Tomatoes love a regular, consistent water supply so water regularly to keep the soil/compost evenly moist. Therefore, fluctuating moisture levels can cause the fruit to split. Feed every 10-14 days with a balanced liquid fertiliser, changing to a high potash one once the first fruits start to set. If you are growing in containers or growbags there will be restricted root space so you will need to feed them more. You will also need to pay close attention to watering. Some self watering planters such as Vigoroot Easy Table Garden and Vigoroot Self Watering Tower Garden will make this easier however, containers generally do require frequent watering.
Pests & Diseases
Blossom End Rot: the bottom of the fruit turns black and becomes sunken. It is mainly due to irregular watering, together with a lack of calcium in the soil. Consistent regular watering and feeding will help avoid this disease.
Blight: this causes the fruit and foliage rot and is most common in wet weather. Avoid planting in areas that have had plants with the disease in. Instead, grow your tomatoes elsewhere in containers and leave these areas to rest for a year or two. Furthermore, choosing a blight resistant variety of tomato in the first place is also a good way to avoid blight. Leaf mould: mainly a problem for greenhouse grown tomatoes. Therefore, rarely seen in outdoor grown ones. Yellow blotches develop on the upper leaf surface and a pale, greyish-brown mould growth is found under the leaf. It causes significant yield loss. To avoid this, keep the greenhouse well ventilated or choose a resistant variety of plant. Tomato splitting and cracking: This is to be avoided where possible as it leave the plant open to infection. Consequently, a fungus, such as grey mould may get in. To avoid splitting keep the plants comfortable by controlling temperature and sunlight levels carefully. It is most important to feed and water regularly to maintain a constant soil moisture level. Companion planting Growing garlic and nasturtiums near your plants will help deter bugs.
Pick the fruit when it is ripe. However, at the end of season you may have green tomatoes and not enough sunlight to ripen them. If this happens then you can either make delicious Green Tomato & Apple Chutney or you can try and ripen them. The best ways to do this are:
- lift the plants with unripe fruit and lay them on straw under cloches
- place fruits in a warm, dark place and wait
- put the green fruit in a drawer next to a banana, which will release a gas that aids ripening.

Try something new?
If you have grown tomatoes before and at this point in time want to try something extra to boost your crop then tomatoes respond well to inoculation by mycorrhizal fungi. The fungi and the tomato plants have a symbiotic relationship. The fungi form a network of hyphae which transport water and minerals to the plant and in return the roots produce sugars to nourish the fungi. Mycorrhizal fungi are available as a powder to coat seedlings when planting out.
