Sowing Months Flowering Months Harvest Months

Water tomato plants frequently, to keep the compost evenly moist. Feed tomatoes regularly with a high potash plant food once the first truss of fruit has formed.

Tie the main stems to their supports and remove any sideshoots that develop between the main stem and the leaf stems. Once the plant has produced 6 or 7 trusses, pinch out the top of the main stem. This process of "sideshooting" and "stopping" will increase the availability of light and air movement around the developing fruit, and focus the plants energy on producing a good crop of high quality tomatoes. Tomatoes can be harvested as they ripen from July to October.

For greenhouse cultivation: sow from February to April.

For outdoor cultivation: sow from March to April.

Sow seeds on the surface of a good, free-draining, damp, seed sowing mix and cover with a fine sprinkling of compost or vermiculite. Place seed trays in a propagator at a constant temperature of around 15-20C (59-68F) until after germination, which takes 7-14 days. When seedlings gain 2 true leaves, transplant into individual 7.5cm (3") pots of compost and grow on at a minimum temperature of 15C (59F).

When growing in a glasshouse tomato plants may be transplanted at the end of May or when the first flowers are showing, if earlier. Allow 3 plants per growbag, or one per 25cm (10") pot, or plant tomatoes directly into the greenhouse soil.

When growing tomatoes outdoors, wait until all risk of frost has passed before transplanting tomatoes. Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting out from early June when tomato plants are 20cm (8") tall. Choose a sheltered position in full sun on fertile, reliably moist, well drained soil, and transplant at a distance of 60cm (24") apart. Drive a (5') cane into the soil adjacent to each plant to support them as they grow, and tie each main stem to its support with soft garden twine.

A Tomato Superb 2016-09-25

Grew this tomato in my polytunnel and everyone who tasted the tomato are still saying a couple of years later, that it was the best tasting tomato they have ever had. The result is now I have to grow this every year from now on. I need a bigger polytunnel to keep trying new tomatoes and keep Cristel as my permanent crowd pleaser.

Excellent tomatoes but getting expensive. 2016-01-30

An excellent tomato I have grown for several seasons. I have had no problems with blossom end rot at all and found them to be good sturdy plants. The only problem is the price which is now £2:99 for an average 6 seeds.

Best Tomato 2013-11-09

One of the best tomatoes I have ever grown. Well worth trying. I have grown in the greenhouse.

Finest flavoured tomato I have had in almost half a century of growing them 2013-08-10

An excellent tomato with large fleshy dark red fruit with a wonderful flavour. Perhaps the best tomato I have ever tasted in almost half a century of growing them. However, although it is high yielding and consistently greenback free, it does seem to be more prone to blossom end rot than most varieties I have tried.

cristal tomato 2011-11-20

exelent large firm fruit. i have grown cristal as a main crop for six years, they are firm favorates with friends and family.

Best ever tomato 2011-09-03

Since trying this variety about three years ago I was so delighted, I will always choose this again. Its got a superb flavour and is easy to grow and versatile to use. I have no hesitation in recommending it. I have always grown it in a greenhouse and it has done equally well in large pots or planted in the ground
