Improving soil condition is about adding good soil if possible or adding organic matter - compost, manures, plant residue, grass clippings, veggie scraps etc to the soil and letting it all decompose - could take a few months. As for what to plant ask the locals what grows and what doesn't. I assume it is hot and wet so that rules a lot of things out. Look around and see what grows and have a go.

Hi, I am planning to move to Mount Victoria up in the Blue Mountains and was wondering if cucumber can grow in the cooler climate? Thanks!

You should be able to grow cucumbers successfully at Mt Victoria even with a longer winter as you get hot summers. Plant the seeds indoors in September in egg carton cells ready for transplanting into the garden in October. Plant the carton cell as well, it will rot. You can plant seed up until mid December. Choose a warm spot with good air circulation to reduce mildew problems. Growing them on a trellis is also beneficial.

Had such wonderful success with cucumbers in the summer of Jan - March. Will cucumbers grow in any other months in Endeavour Hills, Melbourne, Victoria? Question 2. I do not use any chemicals so have you a good idea of how to keep those moths away from Kale? If I put bird mesh over, the moths poke their noses tongues through.

To control cabbage moths and butterflies you could use Yates 'Natures Way' this is a safe organic spray and is harmless to everything except caterpillars. I have also heard of mixing bicarb soda and flour 50/50 and using as a dust. I haven't tried it but others say it works. It wouldn't cost you much to give it a try.

Cucumbers like frost free conditions so can be planted after the last frost. Try planting them in September in egg carton cells or toilet paper cylinders and keep them inside on a sunny windowsill. They can then be planted out in late October when the soil has warmed up. Most summer crops can be planted in late October in southern Victoria. You often hear people say 'after the grand final' or around Melbourne Cup as this is about when the soil normally reaches 17 degrees.

Cucumbers can be planted in Adelaide in the spring and summer. they like a good trellis to climb on and the tips can be pinched to encourage bushier growth. To reduce the chance of sunborn on those scorching days plant them along an east facing fence if you can. This will shelter them during the hottest part of the day. The other alternative is to plant a block of sweet corn and when the corn has taken off plant the cucumbers at their bases. This will give you free shade, free stakes and double crop! The stalks could also be used to support peas in the autumn and winter. Trust this helps.

The rules of companion planting indicate that cucumbers and tomatoes/potatoes should not be planted in close proximity to one another. Let's consider what companion planting is all about first. 1. Companion planting is about creating a diversity in the garden that reduces the chances of PESTs/disease wiping out your garden. So in CP you don't plant things that are prone to the same diseases or attract the same pests close together. In the case of cukes and tomatoes it is: fusarium wilt and powdery mildew. (there could be more things...but this is enough that you have violated one of CP rules). 2. CP is about nutrition in the soil -- that is, you would not plant two things in close proximity that both require heavy amount of any particular mineral/vitamin. So for example if both plants are heavy feeders of potassium -- clearly they would compete too heavily for this resource most likely all plants would not get enough potassium. Cucumbers are heavy feeders and require lots of nitrogen and potassium. Pale, yellowish leaves indicate nitrogen deficiency. Leaf bronzing is a sign of potassium deficiency. Potatoes LOVE potassium, and low levels of potassium cause hollow heart (the middle of the potatoes looks like it is rotting), further the potato plant needs ALL it's potassium at the early stages (BEFORE setting tubers). Potatoes are also HEAVY feeders. Tomatoes are HEAVY feeders. So CP says not to plant heavy feeders next to each other... they compete to much for nutrition. Ok, so now you know why CP says not to plant these plants next to each other. The question then becomes.... but CAN I still do it knowing about the wilt and mildew and potassium and general heavy feeding of all the plants.... SURE, BUT be sure to add lots of nutrition to the soil (compost/manure) add lots of potassium (before planting mainly) and be sure to top up the nutrition during the growing phases... so maybe add manure/compost before planting, mid season and again when fruit starts setting. Also all these plants LOVE water... and lots of it, and this to me, makes it convenient when watering, to have my water lovers all in one spot... that way I can just dump a 5 gallon bucket of water int he middle of them. Also, careful how you trellis the cucumber, you don't want to create a roof over the tomatoes/potatoes that will hold moisture and encourage the mildews.
