Carrot harvest via vegetables matter blogspotAs the heat (hopefully) builds, July’s the time to ease off and work smarter, not harder in the garden, and actually take time to enjoy it!

1. Food, glorious food…

  • Get a bumper vegetable harvest – now’s the time to reap a lot of what you’ve sown, but there’s still time to plant extra crops – like carrots
  • Pick courgettes before they become marrows
  • Sow chard for a winter crop
  • Summer prune redcurrants and gooseberries once the crop has been picked (or do it at the same time)
  • Keep an eye on the watering and try to do this early or late in the day to avoid evaporation during hot spells
  • Keep on top of the weeding in your food crops

2. Extend your flowering season

Now we’re in July your garden maybe just past its peak, so take some action to prolong the flowering value of some plants:

  • Cut back early-flowering perennials to the ground and they will send up fresh leaves and maybe even the bonus of some extra late-summer flowers (e.g Geraniums, Nepeta)
  • Give them a boost after pruning with a good soak of water and some tomato feed
  • Exploit plants’ desperate need to set seed by removing blooms as they fade. This will encourage them to produce more flowers to replace them
  • Remember that plants in containers are dependent on you for their water as they’ll get little benefit from any rain. Give them a good soak at least once a day in sunny weather

3.   Look after your pond

  • Look out for any yellowing leaves on water lilies and other water plants and remove them promptly- allowing them to fall off and rot in the water will decrease water quality and encourage algal ‘blooms’
  • Remove blanket weed with a net or rake to let oxygen into your pond. Remember to give aquatic life a chance to get back to the water by piling the weed next to the pond for a day. Add a football-sized net of straw to your pond (you can use old tights or stockings) to reduce the nitrogen levels if  blanket weed is a continuous problem
  • Top up water levels. Water can evaporate rapidly from water features and ponds in the height of summer, so top them up if the water level drops significantly. Fresh rainwater from a water butt is best – chemicals in tap water can affect the nutrient balance in the pond

    Water the greenhouse early or late in the day

4. Stay watchful in the greenhouse

  • Check plants daily, and once again, water first thing in the morning or in the evening to reduce water loss through evaporation
  • Harden off and plant out any plug plants that you have been growing on
  • Damp down your greenhouse on hot days to increase humidity and deter red spider mites; placing a bucket or watering can of water inside can help to maintain humidity
  • Open vents and doors daily to provide adequate ventilation
  • Use blinds or apply shade paint to prevent the greenhouse from over-heating in sunny weather

    Relax (note the old pallet turned into a stylish lounger) and plan ahead...

5. Relax in your Deck/armchair and…

  • Order catalogues for next year’s spring-flowering bulbs
  • Order perennial plants online now ready for autumn delivery
  • Think about which bulbs you would like for next spring – now is the time to order ready for autumn planting
  • Make a note of your garden’s pros and cons at this time of year to remind you of any changes that you need to make for next year – and take photos so that you can accurately see what it looks like once things have died down
  • Have a leisurely walk around the garden and use string of different colours tied to the stems of plants you are marking out for removal, division etc.
Encourage pest predators like hoverflies by attractive plantings and think about creating winter habitats now

6. Strengthen your alliance with nature for pest and disease control…

  • Look after your aphid eaters – ladybirds, hoverflies and lacewings feast on greenfly and blackfly so it is worth protecting them by avoiding pesticides which will kill them as well as the pests. And why not take steps now to prepare suitable winter habitats for these and other ‘gardeners’ friends’ – e.g. bug hotels, timber piles, areas of long or rough grass or nettles etc.
  • Look for aphids on the underside of leaves – rub them off by hand or spray with an organic insecticide to prevent them multiplying
  • Keep an eye out for scarlet lily beetles on your lilies – remove and crush any you see. Also check for the sticky brown larvae on the underside of leaves
  • If your plants are wilting for no obvious reason then check for vine weevils by tipping your plants out of their pots and looking for ‘C’ shaped creamy maggots amongst the roots – treat with nematodes if vine weevils are spotted
  • Tidy up fallen leaves, flowers and compost – this will prevent potential pest and disease problems

7. Stop plants drying out

  • For recently planted large shrubs or trees, leave a hose trickling around the base for an hour. The same goes for established plants in very dry periods – pay particular attention to camellias, rhododendrons, azaleas and hydrangeas which will abort next season’s flowers if they get too dry. Mulch around the roots when moist to help avoid this.
  • Recently planted hedges are best watered with a trickle hose (a length of old hose punctured with little holes) left running for an hour or so

8. Give houseplants a summer holiday

  • Many indoor plants benefit from being placed outside for the summer. Moving many plants out of the conservatory will save them from baking under glass, and lessen some pest and disease problems, such as red spider mite
  • Ventilate and shade sunrooms and conservatories to prevent scorch damage to remaining plants
  • Water houseplants freely when in growth, and feed as necessary (often weekly or fortnightly)

9. Paint your wagon…

  • Give woodwork like sheds, fences, pergolas etc. a lick of paint or preserver, while the weather is dry
Give your shed and other garden woodwork a fresh new look when the weather's dry.

10. Gimme shelter

  • Slow down and give yourself and your plants a rest from the heat; fix temporary awnings to provide shade in the hottest part of the day – for you and your tenderest plants!

constant gardenerIn this third article about climate change and the garden (originally published in 2013), I set out some ideas on how the gardener can manage the day-to-day garden environment and other short-term measures to modify the impact of abnormal weather events. As previous articles have outlined, these seem likely to become more frequent  as a result of the warming of the planet and associated climate changes around the world.

I think it’s fair to say that effective gardening in the future will rely on gardeners:

  1. Being well prepared for abnormal weather events  and taking steps to change the design, planting and systems in the garden to cope (the subject of my previous article)

  2. Being aware of, and using, a range of information about the weather, plants, pests etc. (I’ll look at these issues in my final article), and

  3. Developing gardening skills and techniques as well as a flexible, ‘can do’ attitude – or what I’m calling the ‘Constant Gardener’ –  the subject of this article.

‘Constant’ implies dependability, ongoing attention and responsiveness,  qualities that the ‘climate change gardener’ will need if the gardens of tomorrow are to be as productive, beautiful and healthy as today. Just like Justin Quayle’s ‘gentle but diligent attention to his plants’ in the film of the same name, in fact!

The focus of the Constant Gardener is on how those annual and biennial plants that we raise from seed can be nurtured and protected from the worst excesses of the weather. However, attention to how perennials, shrubs and trees are faring will also require vigilance throughout the year and possibly remedial action, if the weather threatens to harm a particular plant or area of the garden.

So, what can the Constant Gardener do?

A moveable awning or sun shade like this could help to protect tender plants from the hottest part of the day
A moveable awning or sun shade like this could help to protect tender plants from the hottest part of the day
  • To cope with periods of hot sun, consider temporary shades that can be moved around the garden to provide protection for tender plants where there is no natural shade – e.g awnings slung between posts which can be moved to shade beds or borders at risk from ‘frying’. I mentioned the value of permanent structures like pergolas and arbours in my last article.

  •  To ensure successful nurturing of plants from seed, sow in smaller quantities and in successive batches – especially if you’re growing food, where successional sowings will in any case give you (hopefully) a steady supply rather than a glut followed by nothing.

    Sowing seeds in small batches at different times of the season can help to thwart the impact of abnormal weather - especially on food crops

  • Carry out plant propagation and nurturing under cover and in frost free spaces ideally you will have in place a variety of growing conditions, light frost-free rooms in the house, greenhouse/conservatory and cold frame – make sure you use them effectively to harden plants off before they are fending for themselves outside.

  • Choose plants – especially fruit and veg – from varieties that you like to eat and which are resilient or suited to the sorts of conditions you’ve created in your garden and the weather extremes that seem likely (though this itself may be increasingly difficult to predict). For a ‘belt and braces’ approach, grow a few different varieties if you’re not sure about the best ones for you and your garden. Your choice may also mean that you’ll need to compromise  a bit on quality as a trade – off for resilience.

  • If you’re buying plants, be vigilant about pests and diseases  – with increased plant mobility between countries as well as an increased geographical growing range for some species, the risk of importing pests and diseases is increasing.

  • Delay sowing if your soil is slow to warm up – early sowing is a gamble where the odds are against you, whereas sow a little late and the odds will probably shift in your favour.

  • Be prepared to accept failure and learn from it for next time. Keeping records of seasonal weather, the varieties grown and how they fared is invaluable when growing food crops.

  • If there’s a choice, opt for growing quick food crops – this way there’s less time for them to be affected by abnormal weather.

    Radishes are a quick growing crop

  • Remember the ‘transfer window’ – make sure you prick out, pot up and pot on regularly, before plants give up the ghost or succumb to ‘damping off’. Aim to grow a few strong plants rather than lots of weaklings!  This will make for better resistance to pests and diseases.

  • Rotation plus – you’re probably aware of the importance of moving your food crops around the garden to avoid the build up of pests and diseases associated with one family of fruit or veg, as well as moderating the drain the plants put on the soil’s fertility. The Constant Gardener should also consider successional sowings of the same crop in different parts of the garden if possible (what you might call ‘Divided Bed’ gardening) and if you want to be ultra cautious you could use different varieties too!

  • Protect young plants against frost – use fleece, cloches or other temporary covers

  • If plants have suffered from a wet/flooded winter, give them a spring feed, mulch over the root area and give them a foliar feed during the growing season to build up their strength.

  • Use water harvested from wet periods (in butts, barrels or tanks) to water effectively in dry times. Use pipes and ‘SIP’ plastic bottle feeders plunged into the ground to ensure water gets straight to the plant’s roots. Avoid using sprinklers and hoses as much of the water they deposit on the surface of grass or earth evaporates. You could go for a green solar -powered watering system like the one in the picture!

  • Over – winter tender plants in containers in an inside, well-lit and frost-free room or greenhouse, conservatory, or cold frame (ideally with insulation and the scope for added heat when necessary). If they can’t be moved out of the ground, mulch with  suitable organic material to protect the roots, and for some wrap up the stem and branches with fleece or similar material.

    Some larger, tender plants will need to be wrapped up for winter

  • Keep glasshouse, conservatory and cold frame panes clean to maximise sunlight.

  • Look after wildlife and they’ll look after your garden. Feed birds in tough winter spells and create habitats through planting etc. to attract beneficial insects and other ‘critters’ that will keep pests at bay.

  • Avoid using power tools and equipment if at all possible as these will contribute to the emission of CO2 either directly or indirectly and so fuel global warming.

So, to sum up

  • Constant awareness of what the weather is bringing you and your garden

  • Constant willingness to act in the short-term as well as being prepared

  • Constant action to propagate, nurture and protect your plants!

If you have any comments on these ideas or have some of your own, I’d love to hear from you! My final article will look at plant awards, hardiness ratings, pest and disease information and the future of longer term weather forecasting as ways of keeping the gardener well informed.

To Walter Degrasse

Dear Walter,

As it’s a few weeks since I last wrote, and more importantly the weather today has put the block on any practical gardening outside, I thought I’d drop you a line and update you with what’s been happening in Old School Garden and further afield.

First, I was pleased to hear that your operation was successful and that you can now get back to lifting things – but make sure you do it safely next time!

Well, it’s been rather mixed few weeks, reflecting the March weather! today, just for the record we have the return of ‘The Beast from the East’ – average 30 mph winds and occasional snow  showers whcuin seem to have plunged us right back into winter. Quite a contrast to the weather last week when it reached 14 degrees C! (today there’s a wind chill which will make it feel like -4 degrees!- not that I plan to be out in it). The sort of day that reminds me of the comment one of the vergers at Winchester Cathedral made when he heard Deborah and I live in Norfolk:

‘So, there are about three strands of barbed wire between you and Siberia!’

Winter returns to the Old School Garden

We met him when we paid a visit to this great building at the end of February (you may have seen some of the photos of our trip south on this blog). One of the highlights of that trip was to Mottisfont Abbey where we had a lovely day in bright sunshine. This was perfect for exploring the gardens of this wonderful old estate, especially the relatively new Winter Garden (there is a gallery of pictures of this visit on the blog). The bright sunshine really set off the colours in the winter stems of Dogwoods, Snake Bark maples and Cyclamen flowers (and there were many drifts of snowdrops too).

Closer to home, I’ve managed to make some progress in digging over one of the main mixed borders here, one that didn’t benefit from an autumn clear up. I guess I must be about two-thirds through this and have taken the opportunity to divide and move some perennials (including grasses), so hopefully we’ll have rather more balanced planting as a result. I hope – when weather permits – to get out and finish this, then I’ll feed the main shrubs (with Fish, Blood and Bone) and use my compost to mulch around them.

Talking of mulch, my friend Robert let me have another load of his excellent horse manure so I’ve spread about a tonne of that over most of the Kitchen Garden beds, fruit trees and bushes and roses (having first given them a little rose fertiliser). It really is lovely stuff, friable, and once raked over incorporates into the soil really well.

Apart from this it’s been a few weeks of getting seeds underway. You may recall that I’d started off a few things back in February, but I now think that may been a tad too early, as some of them are struggling to put on enough growth for me to pot them up. Still there’s time yet for having another go. I’ve now got two windowsills and the greenhouse going with seed trays (including a couple of heated propagators), so soon the house will be full of plants at various stages of development as I move them into progressively cooler conditions and larger pots prior to planting out once warmer times have arrived.

One indoor plant that is doing well is the Clivia I bought at the School Fair a few years ago. I must admit that I probably should have potted this on a few months ago, but this doesn’t seem to have held it back, as it’s just about to burst into flower (and we have last years stalk with a seed fruit on it for added colour!).

I’ve returned to the gardens at Gressenhall Farm and Workhouse Museum (you remember I’ve been volunteering here for a couple of years?). The gardens overall seem to be in pretty good shape, but with Steve, a friend who also volunteers here, I’ve begun to clear, dig over and mulch borders in the areas we’re responsible for. I’m also pondering how to make some features of the ‘Curiosity Corner’ for young children a little more robust and secure. Perhaps not surprisingly small feet have wandered off the paths and into the beds so trampling down some plants). Steve has some spare trellis so I might try to put up a low screen of this to deter the kids and at the same time grow some dwarf Sweet Peas up it for fragrance and colour.

I’ve also begun my regular Thursday ssessions at the local Primary school. The School Garden there is now really taking off, with much more structured use to which I’m contributing. So far this has focused on what we do in the garden in spring, digging over the raised beds and talking about tools and tool safety etc. We’ve got some onion sets in as well as some Broad Beans, and potatoes are ‘chitting’ ready for planting straight after Easter. I also got hold of some more manure for these beds, which have rather poor soil, so our efforts at breaking this up and digging in the manure will hopefully be repaid later in the year. The children –  rotating groups from four of the six classes – have responded well and seem to be enjoying the sessions, though they are only about 30 minutes each. I’ll do a final introductory session on Thursday before we turn our attention to renovating the ‘Nectar Bar’ of insect – friendly plans I installed a few years ago, but which has suffered from lack of maintenance. Then, after the Easter break, I think we’ll be into planting potatoes and some of the seedlings the children have been sowing into paper pots (Broad Beans so far but Turnips and other crops to come, some directly into the ground).

Well, looks like coffee time, so I’ll put the kettle on, look out at the snow and try to make the best of the day ahead inside!

I’m currently researching climate change and gardening as this is a topic I expect to be writing a post about shortly. I have a few ideas about what we gardeners might do to cope with not only steadily increasing temperatures (and advancing seasons), but the increased unpredictability of the weather – flood to drought to snow blizzards in as many days! Or as one fellow blogger put it recently ‘Four seasons in a week’ !(we’re not quite up to 4 in a day as per the song).

I’ll be in touch again in a few weeks. In the meantime I hope that your recovery progresses well and that you’ll soon be out and about in your wonderful garden!

Very best wishes,

Old School Gardener
