Waterproof wooden planter

Comment from Iggy Prodromou

Hi All,
Any idea what to use to waterproof the inner of a wooden planter box? Needless to say must be harmless to plants and will be constantly in contact with damp soil.

Comment from Julie burns

Hi, I am trying to re-pot an olive tree as ther are hundreds of ants in the pot but I am breaking the new roots as I am removing the ants. Will this damage the tree? I would be grateful for any advice.
Thanks Julie

Alcea Rosea (Hollyhock)

Question from Stuart Morris

I have a very small alcea which I have been trying to grow in a small pot (3"d). It only ever has 3 leaves, approx 3" high. Every few weeks one leaf goes mottled, and this increases until the leaf curls up, and dies off. Another leaf come up from below but this keeps recurring and the plant is not establishing itself. Is it rust? Is it something else? What do I do?

Evergreen clematis

Comment from Alison Pickford

I have a rather ugly wall and thought I'd plant pots of evergreen clematis like Fragrant Oberon, Cartmenii Joe and Pixie along near the top and let them tumble down in front of the wall. My question is how deep do their roots need? What is the best size pot to use? And is there any reason why this wouldn't be a good idea. I have, in the past, wasted good money on bright ideas that went wrong!

Gladiolus murielae pot planting advice

Question from John Le H

Hi there,
Does anyone have experience of growing these statuesque beauties in a pot to help a novice Glad grower with some questions?:
How many corms approx. should be planted in a round terracotta pot with a 15"/38cm diameter? Web advice says plant 10 cm apart so I'm guessing 9-11. Or is that far too few for a good display?
What mix do you plant them in? I was thinking of 1/1/1 ratio John Innes No2, multipurpose compost and horticultural grit. But then I read somewhere it should be John Innes No1...
Also, I'm thinking of leaving out water retaining gel and watering sparingly as I've read they don't like it wet. Does that make sense?
Finally, has anyone planted anything with GM to good effect? I'm imagining a trailer might look daft in the pot given the height of the Glads (aka Peacock Orchids). Perhaps they are best alone...
Any tips gratefully received! Cheers, John

Camellia Japonica Lady Campbell

Question from anne cutler

I have been given a large CJ Lady Campbell in a pot. We have alkaline soil, so I am reluctant to plant it out in the garden when the warmer weather comes. Will it grow successfully in an unheated garden room/conservatory which is north-west facing and receives afternoon sun? Location: south-east England.

Re-using compost

Question from Ann

Each year we dump the compost from our old tomato pots onto the garden and buy fresh. Has anyone a better idea - can it be used again with the addition of good feed?
