What could you be growing & eating? Hartley Botanic reveals everything you need to know.
Imagine being able to access an abundance of absolutely delicious vegetables and fruit every time you step into your garden? Thanks to our British climate, this wouldn’t be consistently possible for those growing outdoors, but for those who own a Hartley Botanic Glasshouse or Greenhouse a constant supply of home-grown, fresh produce is achievable.
Historic Glasshouse and Greenhouse manufacturer Hartley Botanic has a reputation beyond compare in the horticultural world. They have been making their beautiful and elegant handmade, made-to-order horticultural buildings for over 80 years from their original factory at the base of the dramatic Pennines’ Chew Valley in Greenfield, Lancashire. They have unrivalled knowledge and expertise and are an authority on both Greenhouse growing and Greenhouse ownership. Amongst their customers, a desire to ‘grow their own’ is always a leading motivation when it comes to Greenhouse ownership but Hartley Botanic has seen this become even more relevant in recent years, thanks to veg-based diets and an increasing desire to be self-sufficient.
Aside from trend-led influences, the improvement in taste and quality of fruit and vegetables when you grow your own is well-known and has recently been taken up by hoteliers keen to upgrade further their dining offer. Both Raymond Blanc’s Belmond Le Manoir Aux Quat’Saisons in Oxfordshire and the Forest Side Hotel & Restaurant in the Lake District own Hartley Botanic Glasshouses to provide their chefs with the very freshest and most delicious ingredients.
To help you understand what all the fuss is about, Hartley Botanic provides a taste of just some of the edibles that can be grown in a Greenhouse.
Huge variety of edibles
Probably one of the most common things grown in British Greenhouses every summer is a superabundance of incredibly tasty tomatoes. But there is a vast variety of other easily cultivated edibles to grow. From off-season lettuces to big, ripe aubergines; from hot little chillies to heavy bunches of big, golden muscat grapes, a Greenhouse can be a reliable source, not just of home-grown food, but of the choicest, tastiest and most sought-after luxuries.
A Greenhouse is the stepping off point for outdoor vegetable production. As well as raising tender crops including courgettes and outdoor cucumbers, you can kick-start runner beans, brassicas and even such root crops as carrots and beets. And you can use a little spare space to ‘chit’ seed potatoes, i.e. expose them to light and warmth to encourage their shoots to begin growth prior to planting. A wide range of tender vegetables can be raised in your Greenhouse. Your difficult decision will not be what to grow, but what to leave out, since space is always limited, and you’ll have some hard choices to make.
Year-round production and supply
Your Greenhouse will enable you to be significantly more productive in your growing year, than if you were purely growing outdoors, especially if you know the right growing techniques. For example, with strawberries, if you use specially designed containers with planting pockets down their sides the plants could produce fruit in May and again in November. Summer broccoli, sown in January, may be in production by late June and, if you sow your first runner beans in February under glass and plant them out in May, they’ll crop from late June to September. With tomatoes, even with modest croppers, if you grow your plants well, you’ll always have surplus and nothing tastes quite so delicious as a fresh-picked home-grown variety.
Winter greens and salad
Out-of-season food is something supermarkets have helped us to become accustomed to, and with a Greenhouse you will be surprised and delighted at what can be grown. On Greenhouse beds, after the tomato crop for example, you could grow pak choi or other Chinese greens. They mature fast and if seed is sown in cell trays in August and the crop planted out in early September you should have succulent, leaves and stems by late October. Lettuce or rocket also grows speedily in autumn and winter, but will be less dense and more drawn up or ‘leggy’ than if started in spring or summer. Salad crops such as lettuce can be grown in large pots or growing-bags if there is no border soil. Most seed companies also produce mixes of ‘cut and come again’ salad greens. These can be harvested a little at a time, and if sown at regular intervals, will produce greenery all year round.
While many herbs are hardy and grown in the open garden, some herbs from subtropical regions perform more reliably in the warmer, more humid conditions of a Greenhouse. Many others, such as sage, rosemary and thyme can also be grown in pots in a frost-free Greenhouse over winter to provide you with a continuous supply of aromatic leaves. Basils, of which there are more than 30 different types listed for sale in the UK, revel in warm conditions and have a range of distinctive flavours from aniseed to citrus and are used in a wide range of dishes. The additional warmth of a Greenhouse will also help stimulate the production of the aromatic oils that make the taste of basil so distinctive. They are easily raised from seed or cuttings. You can also experiment and raise your own lemon grass, root ginger, galangal or cardamom. All are easily grown from root divisions, which you can get from specialist greengrocers.
In the day of the great Victorian estates, Glasshouses were used to produce all manner of off-season and exotic fruits, from figs, peaches and apricots to bunches of big, luscious grapes and even pineapples. Even if you don’t have a vast, stately Glasshouse, you can still produce a whole range of delicious fresh fruit crops.
Grapes - The quality of grapes grown under glass in Britain is greatly superior to any harvested outdoors. Extra close attention given to your vine will reward you with superb grapes on large, well-shaped bunches. Ideally, the vine rootstock is planted outside, with the main stem fed through into the Greenhouse. This enables the roots to quest for nutrients and water over a wider area while the remainder of the plant is cosily inside where the ripening fruit benefits from the longer, warmer growing season. But vines grown completely within a Greenhouse will grow almost as well and you can even take modest crops from vines grown in large pots.
Wall fruits - In lean-to Greenhouses, provided their high back wall receives enough sun, fruit trees – usually fan-trained – will be amazingly productive. Peaches, nectarines, apricots and figs are the best ones to try if you have the wall area. In limited space, dwarf trees can be grown in large pots to produce more modest crops. In summer, such little trees can be lined up or arranged outside.
Citrus - Producing your own crops of lemons, kumquats or calamondin oranges is a real possibility under glass, but the sweet-scented flowers on these evergreen trees and shrubs are reward enough. Grow lemon ‘Verna’, lemon/ orange hybrid ‘Meyer’ or calamondin orange in pots, with a minimum winter temperature of 5°C.
