As we come to the end of August the sun is shining here is Marshalls but that definitely has not been the story all summer. It’s been a really mixed year of sun, rain and winds but still the crops are fruiting well.
Our new tomato Montello is thriving in my garden at the moment, I don’t think I have seen such a prolific cropping tomato (or eaten so many tomatoes). I can’t wait for the RHS Malvern show at the end of the month when I will have the chance to see your exhibits of Montello and see what you thought about Montello.
Before we get to Malvern we also have the Harrogate show, where James Oakey our Head of Horticulture will be there with the National Vegetable Society, make sure you pay him a visit if you’re at the show.
Don’t miss your NEW Marshalls catalogue landing on your doormat next week. It’s full of great offers and savings plus some exciting new products. My favourite is Blackberry Cascade – at last those of us with small gardens can enjoying picking blackberry’s at home.

You won’t be disappointed in growing misted-tip-treated strawberries now for earlier harvests next year. The soil has warmed up well from the summer and provides the perfect soil environment for potting on young strawberry plants suitable for planting in baskets, containers or open ground.
- To plant, dig a shallow hole with a trowel, but create a central mound within the hole.
- Replace the surrounding soil so that the crown (where the stem starts from the roots) of the young strawberry plant is flush with the soil level.
- Water well.
Once planted up, the roots establish well and quickly and they initiate flower buds in autumn. These buds stay dormant over-winter while the rest of the plant becomes really tough from winter weather. They then burst into life next year, fruiting sometimes as early as May.
The misted-tip process is a highly effective propagation technique that produces strong, ready-fruiting plants. Our expert growers expose strawberry runners to mist creating a suitable, humid atmosphere for developing plants to root readily. They’re then at the perfect stage of development for you to re-plant at home and get a generous harvest earlier next year.
The young plants come from healthy disease-free mother plants, have the same genes and carry the same strong characteristics.
Green manure suppresses weeds, protects soil from erosion and improves structure as well. Legumes (beans) absorb nitrogen from the atmosphere and ‘fix' it into the soil through root nodules making it easily available for crops planted afterwards.
Sow green manure seeds whenever the ground is to be left bare for more than 6 weeks. Dig them in while they’re fresh and green and leave 2-3 weeks before planting your new crop. This allows the breakdown of plant material into humus, releasing nutrients slowly over time.
You can sow green manure crops either by scattering seeds over the vacant site (broadcasting) or sowing the seeds of green manure crops separately.
You’ll want to dig the crop into the soil when it’s relatively young. This is for ease of working it into the soil. If you are away and not able to dig the crop in until it is woodier and more established, you could trim the crop off with a string trimmer, let it break down and then dig in.
Fast-growing leafy crops like Phacelia and rape seed will release lots of nitrogen in the soil when dug in. Effective but risky to use rape and mustard in soil that has been affected by clubroot.
Legumes like peas and beans fix nitrogen in the soil using nodules on their roots. They also release nitrogen from their leaves as they break down. Check which ones would be suited to your climate as some may not thrive in cold weather. Tares tend to do OK in less than clement conditions, while fenugreek is better in warmer climates.
Flowering green manures are dual purpose – firstly they produce attractive flowers, great for attracting pollinating insects, secondly the plants can be dug in afterwards after their impressive show of flowers.
Caliente Mustard – Cleanse your soil with Caliente Mustard – Perfect for Onions
White rot is a disease that affect onions and once you have it is impossible to get rid of it. You’ll recognise it at harvest time by fluffy white mould with black speckles around the base of the bulbs. Before planting your onions, plant your green manure. It is a great organic means of creating a soil environment that’s uninviting to the disease. Just sow from any time between March and October for a quick crop before you autumn-planting crops or sow in November to overwinter for planting crops in the spring. Just before it flowers, cut it down and dig well into the soil.

Now that you’ve enjoyed your harvests of summer-fruiting raspberries, loganberries, boysenberries and other soft hybrid berry fruits, it’s time for their post-summer pruning to ensure great yields next year, and healthy growth where stems get lots of ventilation from well-spaced stems.
Prune the fruiting stems with good secateurs after harvests to the ground level. There should be some strong leafy (non-fruiting) stems that have emerged from the ground. Tie these onto the supports, as these stems will flower and fruit the following summer.
If you can, keep neighbouring stems evenly spaced and not touching each other. This keeps pests and diseases down and prevents over-crowding of stems. Water well after pruning.
Treat the soil to some fertiliser – the taking-away of green stems reduces the ability for plants to make their own food through photosynthesis - so a helping hand of fertiliser is very much appreciated by the plants. A layer of bulky compost at the soil surface is ideal at this time of year to lock in the warmth generated by the summer sun.
Top fruit (or pome fruit) includes tree fruit like apples, pears, plums and figs. If you start noticing a collection of fruit having fallen from the tree, it’s a good indicator that the fruit is ready to harvest.
Harvest a regular quantity of fruit daily, rather than a glut less often, picking the fullest and most coloured fruits. Remove by twisting the fruit first and then tugging gently. Pulling fruit off the tree forcefully may damage remaining stems and buds that will develop fruit next year.
Store fruits in plastic bags with small holes for air in a well-ventilated cool, dry place. Or wrap fruit individually in paper in crates. If storing crates one on top of another, be sure air can get in between crates.
Inspect fruit regularly and remove fruit that are rotten or rotting, to avoid moulds and diseases spreading.
Squashes, pumpkins, courgettes and marrows all come under the same fruiting-vegetable family- the cucurbits. They’re fun to grow, especially with children and easy to sow on account of their large seeds.
Keep the growing area well watered, but keep water physically off the leaves and add a mulch of bulky manure around the plants once they have started to flower and fruit.
Avoid fruit rot and powdery mildew by watering regularly. It’s the roots that really appreciate the water so fit a pipe nearby to the plants and water into the pipe get water down to the roots. This is more effective than watering near to the surface where rot can creep in.
If you can, water using rainwater – this is usually at an appropriate temperature and pH for cucurbits to really thrive.
Autumn-planting allows really robust, full bulb crops to form that are weather-hardy and less prone to bolt. There’s nothing more flavoursome than home-grown onions to add to home-made sauces and soups. With the right preparation, pest and disease prevention, and aftercare you’ll be rewarded with healthy, full bulbs from early to late-summer.
In September to November plant sets pointy side up straight into the soil outdoors at 7-10cm (3-4in) intervals in a row, and space rows at 30cm (12in) apart in an open, sunny site in fertile soil that is well-draining yet moisture retentive.
In spring, you can boost post-winter growth by apply a seaweed-enhanced feed, rich in phosphorous for stimulated root growth to encourage full and flavoursome bulbs.
For onions, lift when the foliage has wilted and yellowed in early to mid summer. Lift carefully with a border fork, dry in a cool, light place for two to three weeks before using in the kitchen.
For shallots lift with a border fork once you notice the leaves have gone yellow. Separate the clusters, clean off soil and grit, and dry in a cool light place for one to two weeks. In wet weather bring into a garage by the window. In dry, sunny weather leave outdoors or in a well-ventilated greenhouse.
Onion ‘Shakespeare’ is an improved Japanese variety, perfect for autumn planting when it can be harvested from late May. Radar is loved for its mild flavour storage potential; under the right conditions it will store for about a year. A good variety with resistance to bolting.
Shallot ‘Yellow Moon’is round with an attractive yellow colour. It has a low sensitivity to bolting and produces a very healthy, uniform crop with excellent skin quality.
Garlic ‘Provence Wight’ is a vigorous, white softneck garlic that produces really large bulbs. Originally from the fertile valleys of Drome region of Provence, it has proved to grow well in the UK. The fat, juicy cloves are perfect for adding some Mediterranean flavour to both vegetable and fish dishes. Once lifted, it will keep until January.
Tell-tales signs of affected plants include silvering of the leaves in summer. Also a cross section of a stem will show a dark stain in the wood. In late summer the fungus affects the branches, which consequently die.
Control this disease by pruning plums and relatives in mid-summer. There are fewer silverleaf spores in summer than in autumn and winter, so there’s less chance they’ll enter the pruning wounds. Pruning wounds also heal more quickly in summer than in the colder months.
