How To Grow Cucumbers And Squash

Hi Guys

At long last…better late than never I have planted up my cucumbers and squashes….yey 🙂 Cucumbers are one of those veggies that you either love or hate.  I love homegrown cucumber but really don’t enjoy shop bought ones, similarly I feel the same about homegrown and shop bought tomatoes.  Cucumbers and squashes are member of the cucurbitaceae (curcurbits) family along with vegetables/fruits such as melons, pumpkins and courgettes/zucchinis.  They are all pretty similar in a lot of ways as they generally produce both male and female flowers (although there are some all female varieties available).  Their fruits swell, they contain a very high proportion of water and prefer a warmer environment to grow well.


The cucurbits family love the sun, need plenty of water and a good fertilizer once the plants start to produce flowers…again I use tomato feed for this purpose.  I have in the past tried to grow cucumbers and squashes outside but in recent years have found this very difficult due to the vast amount of rain we have been getting, as when the flowers of the squash family fill with water the wet  pollen doesn’t set fruit in the same way as dry pollen (when growing under cover  try not to wet the flowers too much when watering).  I find growing under cover no problem at all and get more cucumbers and squash than I know what to do with….I do have a few preserving recipe tips for the ‘cucs’ which I will share with you as we start to harvest.

Planting your cucumbers and squash is quite simple…watch the you tube video for instructions on how this is done and don’t forget to subscribe on the link below the video so that you don’t miss out on more great tips and advice on Garden Of Eve 🙂

Feeding your cucumbers and squash should be done on a weekly basis, I feed all my flowering fruit and veg with fertilizers such as tomato feed, homemade liquid seaweed or compost tea.  The cucurbit family are pretty heavy feeders and need plenty of nutrients so feeding is essential if you want to get a good crop from your plants.

Male And Female Flowers And Pollination

The female flower on the cucumber and squash plant have a small swelling behind the flower which will become the cucumber or squash, the male flower however only has a thin stem and no swelling.  There are some all female species which do not need pollinating and will produce fruit without any problems, but most of the plants produce both male and female flowers and they need insects to pollinate the flowers in order to produce the fruits.  When growing under cover it is very important to open doors etc to allow the insects in….some uninvited as well as the ones we want 🙂 The experts will say that you need to remove the male flowers as the cucumbers can sometimes be bitter and very seedy if you dont…I dont always do this and very rarelyhave had  bitter fruits…I do get the odd seedy cucumber though which I dont mind.

The female flower will have a baby cucumber behind it (always the females left holding the babies!!)

When To Harvest

Remember that cucumbers don’t always look like the shop bought variety, they can big, long, short, fat, curved, spiky or even white (I grow a variety including white cucumbers).  Pick these as soon as they are ready and this will encourage the plant to produce more.  Try not to leave fruits on the plant too long as they will produce seeds, go bitter and too much energy will be given over to the ripe fruit and inhibit  the plant  from producing more flowers.

When harvesting your cucumbers always be very careful not to pull them from the plant as the stem is very fragile and can break easily, I either twist the cucumber or use a secateurs or a sharp knife.

Cucumber and squash have very large leaves to protect their fruits from scourging but sometimes they could do with a little bit of shading from the sun (ha ha), I use some green netting which I attach to the inside of the poly tunnel.

A great companion plant for cucumbers and squash is nasturtiums, which has a really pretty flower, trails over the trellis with the cucumbers and squash and the flower petals are edible which makes a really nice accompaniment to your salad bowl! They do grow very large when grown under cover so you only need maybe 1 or 2 plants.

Please Note:

I have been asked by a few of my followers about the bitterness issue when growing your cucumbers and apart from the removal of male flowers if there are any other reasons that the fruits maybe bitter….the answer to this is yes….and why….well in order to prevent bitter fruit, we need  to find out what causes bitter fruits in the first place so if you follow these simple steps hopefully you will have bitter free cucumbers!

Try and keep cucumbers at an even temperature which can be difficult considering the strange weather patterns we are all experiencing right around the world.  If you live in a hotter climate then plant in an area where it is not getting the sun all day (slight shade) and if you are planting in a cooler area (like here :() then you need to make sure you plant your cucumber where it will get full sun.

Always use best practice when you water your plants, making sure you water evenly and regularly, especially if we do get some sunshine 🙂

I hope this information is helpful and that you are not too confused with the male and female thing and bitter cucumbers!!

Happy Gardening 🙂

  1. Lots of useful info. This year I’m trying French pickling cucumbers from Real Seeds. This on the hopes that I might at least get some tiny cucumbers (more polytunnel envy). They’re shivering under enviromesh while the weather goes backwards to winter.


  2. I’m a big home grown cucumber fan but hate supermarket ones. I’m planning on creating a Pimms bed in my spring (sept). I’ll grow the cucumbers up a wigwam in the centre (perhaps mini white variety) and under plant with mint, strawberries and borage. It’s lovely seeing your summer vege garden – very inspiring for me in the midst of winter!


  3. I’ve grown lots of cucumbers in the past but I’ve never heard of removing the male flowers to prevent bitterness(which I’ve had a lot of). I was always told it was because of irregular watering. I will try it next time. Thanks 😀


    1. Hi Dasi
      Irregular watering is another cause of bitter cucumbers along with temperature fluctuations which here in Ireland we get on a regular basis as we can get all four seasons in one day 😦 If your plant starts to produce bitter cucumbers it is more than likely to continue and there is not cure!! It is very difficult to give an exact reason for the bitterness but if you water regularly….and take off the male flowers, hopefully you wont get as many bitter cucs!!

      Hope that helps and thank you for following.



  4. you make an interesting point about companion planting of Nasturtiums and how big they grow under cover.
    I am growing squash for the 1st time under cover and have planted Borage and Nasturtiums alongside and boy are those plants growing big, they are loads bigger than you’d get outside in the borders…! – So this should definitely be borne in mind when planting…
    I have Borage plants over 4ft tall already in the greenhouse and they are only just now flowering..


  5. Thank you so much for sharing the male/female information, I actually had no idea about that. I will check my plants when I get home tonight. I am growing both cucumbers ans squash in containers this year and they are doing very well. I will also start feeding them weekly as I have only been doing it every 2-3 weeks up until now. Again, thanks for all the great infor!
