April in the Garden

Jobs and tips for April in the garden, what's looking good, observations, plans.

Jobs / Tips

    Get out and mow the grass as soon as possible if you haven't done so already (I'm writing this in East Anglia - England, but it applies to pretty much the whole of the UK (and much of Europe and North America too). If it's looking a bit tatty it's because it's started to grow! Set the mower a bit higher than normal for the first cut and then follow it up after a few days with a dose of  "feed and weed".

    Begin to look out for weeds and get them as soon as you can. Weeds are always early risers in the spring and are much easier to remove while small than when they get larger. It's a good time to spread a mulch on the bare soil between plants if you haven't done so already, this helps keep the weeds down.

    Protect young shoots from slugs and snails, scatter pellets / slug pubs or whatever particularly around clematis and herbaceous plants (they love Delphiniums). As soon as there are shoots to eat the slugs and snails will appear from nowhere.

    Watch out for early signs of aphids. There will be less if the winter has been cold, but it's about now that they start to come out of hiding and build up their numbers. If you can spot and control aphids early, then life gets an awful lot easier later on in the year. Check the newly emerging shoots of their favourite plants. I gave my plants under cover their first spray last week at the end of March as aphid numbers were already starting to build up, it's easy to miss them as you probably don't check so often at the moment.

    Did you sow all of the seeds you intended? March is the main sowing time for many plants, hardy or half-hardy. I've still got a few packets left that I haven't yet got around to using.

    If you've never tried growing your own vegetables, or grown anything from seed, then this is a good month to sow. I tend to go for things that are either expensive in the shops or difficult to get really fresh. I don't see the point of struggling against the slugs and weather to get a crop of lettuce that I can't possibly eat quick enough at the time when they are almost giving them away in the shops (though you could try lollo rosso, rocket or other such exotics to good effect).

Beans are easy and don't travel well so the ones in the shops are never as good or fresh as home grown. Broad beans are good as are French beans and very easy too. Dwarf French beans don't need all the long canes that runner beans need, but wait until the end of the month though or early May before sowing them outdoors. They can be started off if you like in 3" pots in an unheated greenhouse.

I'd like to be able to grow spinach but it always bolts before it grows very much in my soil. Instead I grow Swiss chard which is similar but likes my garden better, it is also a perennial so I leave it over the winter and it grows up again in the early spring producing long before any current season seeds are anywhere ready. I also discovered (accidentally) that over-wintered beet can be left to produce copious young leaves for salads in spring too even though the beetroot itself is long past its best.

    Lift and divide summer flowering perennials. Get free plants to spread around the garden or your friends and neighbours in the process. They should be fairly easy to dig up with a fork as there won't be many fine roots yet. Pull them apart gently but firmly so that the plant divided at its weakest point/s, don't be tempted to cut.

    Make plans. Consider plants and planting. Put canes or a hose pipe across the garden to mark out planned beds, patios or other features. Then ignore it for a few days, look out of the window and change it all totally if necessary. Take your time when deciding on your grand design and get it right before you start on it when the warmer weather and breaking buds tempt you beyond the confines of the fire-side (whether metaphorical or literal).

April Thoughts

Take time to enjoy your garden and smell the flowers - I sat down at my computer yesterday morning to update this page but was sidetracked by my 5 month old puppy wanting to go out, so I went into the garden with her and the older dog and a mug of tea.

I ended up sitting for about an hour on a rustic chair I've made from old oak fence-posts in the sun under the plum tree that is starting to come out in blossom. There was constant bird song, Brimstone and Red Admiral butterflies and honey bees that the sun had woken up were flying about. The dogs were playing and little one would run up my outstretched legs every now and then for reassurance and a big fuss. There were daffodils, Forsythia, primroses and the scent of hyacinths, the whole garden was in puppy-mode in fact. Make sure you take the time to enjoy your garden.

Two years ago I planted some seeds of wild primrose in a seed tray that went out in a cold frame. Doing things properly I sowed them in the autumn, but didn't expect them to germinate until the following spring. The following spring came - and went, the seeds didn't appear. Doing things properly I left the seed tray in the corner of the cold frame and kept it watered throughout as sometimes wildflowers can take a year or more to germinate. 18 months after sowing the seeds I gave up and threw the contents of the tray on the compost heap.

So why am I telling you this? Well I spent some time in the garden this afternoon when I dug up about a dozen small primrose plants from various spots around the lawn and re-planted them out of the range of the lawn mower. We have some primrose plants in the borders, but we don't get primroses self-seeding there. Lawns are supposed to be hugely difficult and competitive environments for young plants of any kind, but the only success I've had with primrose from seed are these self-seeded specimens in the middle of the lawn.

Is there something to be learned from this tale? Maybe that nature will do what she wants despite your best efforts and so you should just try to fit in with this system than impose your own will which will always be weaker. As for me, I'm very pleased I have a dozen very strong and healthy primrose plants that I didn't know about!

Don't you love the spring? It seems almost corny to love the spring, but not to do so would be to not love youthful exuberance and the promise of treats to come at their best. The garden gets tattier and tattier through the winter, as the buds, flower and leaf, sit there protected waiting patiently for the right moment to emerge. Just as the darkest hour is before the dawn, so the darkest days of winter are just before the spring. Having taken the battering of winter storms and the subtler but more pervasive and far-reaching effects of short days, low temperatures and a lack of growth, the garden really is at its lowest ebb. At this time it is rescued just in time by the express train of warmth, daylight and rising sap.

If you've any rotted garden compost that's ready to use, this is a good time to dump it around the more mature garden plants and trees as a thick mulch. I use up to about half a barrow-load around young trees and large shrubs. It looks a bit odd at first with brown mounds at the bottom of the trunk, but it soon gets mixed in by the worms and continues to rot and improve the soil. The effect is far from immediate, but within a year or two, it's quite noticeable, the improvement in soil texture and the slow-release fertiliser effect it has will boost anything you place it around. Just be careful not to bury small plants with it, or put it where you plan to plant bedding plants over the next couple of months or so - it will help them too, it's just that garden compost tends to be rather too coarsely textured for small plants to cope with.

    I don't know if it's the fact it hasn't been very warm yet or that I'm suffering from a winter lethargy still, but I'm finding it difficult to get going with my planting plans this year. I've some small Surfinia Petunias that I need to pot on to larger containers and seeds to sow, normally, they would be rather late, but I don't think it will make much difference because of the temperatures mean that not much growth has been missed out on so far.

    Spring is a miracle time in the garden. We try to keep the garden interesting in the winter, but I think what really happens is that our expectations change. The few stalwart (but very much appreciated) winter flowering shrubs that seemed so wonderful a month or so ago would be rather dull compared to the embarrassment of riches in the spring when half the world seems to be in flower.

Spring also stirs gardeners into action and sometimes the result is as with spring flowering shrubs. A spectacular effort for a short time followed by very little for the rest of the year. This is I think the reason that there are quite so many spring flowers planted in gardens. The reluctant or seasonal gardener goes off to the nursery or garden centre and buys what looks good there and then. The result - gardens full of plants that look fabulous at the time of year that you first went plant shopping and pretty dull the rest of the time.

Still, I thank them all for making the overall display brighter and more exuberant if a little too fleeting.

    330 days of mowing the lawn - Climate change is meaning that we are getting more and more growing days in the year. In central and southern England, there are now 330 days in the growing season, more than a month more than there was a century ago. Over the last 20 years the pace of change has accelerated giving an extra day per year. This according to the Tyndall Research Centre for Climate Change Research at the University of East Anglia. The growing season starts when the average temperature is over 5°C for five consecutive days and ends with five days below  5°C. The blame lies with the greenhouse effect due to a build up of "greenhouse gases".

The immediate effect on the gardener is that everything is growing longer and shooting earlier, grass, spring bulbs, spring buds etc. In the autumn, things are happening later, last year beech leaves turned colour on average 3 days later and field maple 5 days later. Many birds too are leaving later in the season or in some cases not at all. It also means that pests such as aphids are not being killed off as they used to be

     Rory - Winter's over as far as my resident robin and his robin rivals and blackbird chums are concerned. The birds are to be seen more and more with twigs, straw and the like in their beaks, and they are all more interested in each other, as mates or rivals, almost as much as they are in the food that I put out.

Why do birds like bread so much? I've tried all sorts this winter, all kinds of left overs have been placed on the bird table to tempt the avian palate. Here's me worrying about supplying a balanced diet, whatever I put out, the bread always goes first. I've had to take down bits of prime fat cut from gammon joints because they're in danger of going rancid before they're eaten. I've put out chicken carcasses (we've a walled garden and cats rarely get in) expecting them to be picked clean. The odd starling has had a bit of a go at it, but it's always the bread that has gone first. They even seem to prefer white to brown irrespective of species, robin, blackbird, blue tits. collared dove, whatever.

Perhaps it's the bird equivalent of fast food, or maybe it's more comforting when it's cold and miserable.
