Sowing
June is the month to keep on sowing lettuces and salad leaves for a continuous supply. The cut-and-come-again salad leaves are great, you can pick as much or as little as you like and let the rest keep growing. You can buy seed packets with mixed leaves in the garden centre. I have planted a spicy mix this year. Rocket and spinach can be sown like this too and both are good in salads. Spring onions can also be sown this month as they are relatively quick to grow.
For a quick salad ingredient, why not try radishes. The will be big enough to eat in around 6 weeks. Try succession sowing – sow a few every week to keep you supplied throughout the growing season. You can also put in some beetroot seeds at the start of June. As temperatures are a bit warmer (hopefully!) they should germinate quickly.
Growing
The start of June is the time to plant out the more tender vegetables such as courgettes, pumpkins and sweetcorn.
Courgettes and pumpkins are ‘greedy feeders’ so when planting you should incorporate plenty of home compost, well rotted manure or you can buy bags of farmyard manure from the garden centre. I usually dig a hole and mix in my compost then put in the plant. I create a saucer shaped dip around the plant to help with watering and then mulch it. Mulch can be many things: shredded newspaper, cocoa shells, grass clippings. I discovered something this year called ’strulch’ which is a straw based product (from www.wigglywigglers.co.uk) that so far seems to be very effective at preventing weeds . Mulch also helps to retain water in plants and courgettes and pumpkins need plenty of water to develop.
Sweetcorn should be planted in a block formation rather than in rows to encourage pollination. I have had success with mini corn but am still experimenting to find a bigger variety that will grow well outdoors.
While on the topic of pollination I always plant some flowers in beside my courgettes and pumpkins. This is to help encourage the pollinating insects. I usually use cornflowers, convolvulus, poached egg plants and marigolds (marigolds are also good companions to tomatoes and help to deter predators). It also looks good!
I was watching Gardener’s World last week (Fridays, 8pm BBC2) and saw Joe Swift planting fennel in with his brassicas (broccoli and cauliflower) to prevent the moths from laying eggs. I always have problem with the cabbage moths and caterpillars and end up with naked stalks on the broccoli so I think I’ll give this a go and see what happens. If you haven’t already put out your broccoli and summer cauliflowers then now is the time to do so.
Also with French beans and peas, if you haven’t planted them out then go for it! I’ve put nasturtiums in with my climbing beans this year and am hoping this will help with pollination. Should look great climbing up the wooden wigwams.
Harvesting
The beginning of June is full of anticipation I always think as I can see the potential harvest in the garden but there’s not an awful lot ready!
If you are lucky enough to have asparagus in your garden, you’ll be harvesting the last of it at the start of June. Make sure you leave some spears to grow into ferns to revitalise the crowns for next year. I watched Hugh Fearnley-Whittingstall do interesting stuff with asparagus last week (Wednesdays, 9pm Channel 4) – see this months recipes.
I have a lot of herbs in full flower (chives, thyme, savoury, rosemary, oregano) and have sorrel, lovage, chard, Good King Henry and the beginnings of salad leaves. My wild rocket has over-wintered beautifully and is delicious (not as strong as cultivated rocket). The rhubarb is just about finished but I have a few big stalks left.
