June Gardening Newsletter

Dear Fellow Gardeners,

Who would have thought that we get such a wonderful summer with two prolonged hot spells and that it even made it to Leitrim.   July is the month where we can enjoy the fruits of our labour.  I’m always looking forward to the first tomatoes. I still had a few seeds of my favourite (and unfortunately extinct) variety Rosada F1 left.  Many tomato lovers will agree with me about the amazing flavour and texture of this variety.

I entrusted the seeds to Colman – a young organic grower in Cork where I visit the plants once a month.  In his tunnel we planted 5 plants and took side shoots to make another 10 plants.  Unfortunately as it is a F1 hybrid, the seeds won’t come true to type. Another friend and organic grower from Wicklow has tried to create an open-pollinated type of Rosada – but none has equalled to original.  I’m not sure if he still continues with this experiment.

Anyway – as these were my last seeds – it might be the end of one of my Rosada growing.

However, I heard from Charles Dowding that he propagates new plants from side-shoots in late summer and manages to keep these young plants and overwinters them – probably in a frost free conservatory and plants them in the following spring in the polytunnel.  I set Colman the same task and hope he’ll manage it.


I realise that many people were overwhelmed with the number of emails they received during GDPR deadline.  So please if you no longer want to receive the monthly newsletter – you can click UNSUBSCRIBE on top of the email.


Jobs to do in July:

The dry weather keeps gardeners busy with watering.  This is one of the very few times where I also watered outdoor vegetables, but with a possible hose-pipe ban pending – here are a few tips:

If you water your plants give them a thorough soaking.  Watering little and often is a disaster as it brings the plant roots up instead of encouraging them to go down.  This is probably worse than not watering at all.

If water is in short supply concentrate on the crops that need it most.  These are newly transplanted crops, seedlings which don’t have a deep root system, leafy crops (salads) as well plants growing in raised beds.

You can still sow lettuce, parsley, scallions, annual spinach, perpetual spinach, chard, kale, kohlrabi, turnip, radish, Chinese cabbage and Florence fennel as well as all the oriental salads (rocket, mustard, pak choi, mizuna etc).  If you have an unused bed you can sow phacelia as a green manure crop.

Aphids tend to be a problem in mid summer especially in more sheltered gardens and in a tunnel.  Watch out for ladybirds or hoverflies as they may already control them.  If aphids are a big problem they can be sprayed with pyrethrum or soft soap, but both sprays will also harm ladybirds.  Aphids can also be washed off plants with a strong jet of water.  Keep checking your brassicas for butterfly eggs.
