I have a natural stone retaining wall and I am thinking of adding some wall flowers or perennials that would droop over the wall and give some added colour. I don't want them to take over as the wall is very nice so I am thinking they would droop over no more than one foot or so. Thank you for your time. We have recently buit a pergola and would like to plant wisteria with intention that it will cover it in time. However we have been told that the planters are too small to have wisteria they measure 36inchs x 14.5 inchs & 18.5inchs deep and built of brick. Would you think they are too small ? The pergola has 6 sets of planters and posts, if we do have the suitable size how many plants will i need to achieve complete coverage. i have sent you a photo. If its a case wisteria would not be suitable what could you recommend insteadCan you suggest any flowers that would work and also that would be perennial? Are there any that would flower for most of the summer?
I put 5 japanese azaleas in different parts of the garden about two years ago and they are not doing well at all. The did flower earlier in the year but poorly. Do I need to feed them?
I have a number of blue and purple Hydrangeas that are doing quite well but recently I noticed a lot of black spots on the leaves and stems. Is this something to be worried about?
I built a new lawn from seed on a sloping site last year and it has done really well. During the last year, as the ground settled, I have some dips in the lawn. I have access to some topsoil and am thinking about trying to fill some of these dips to get the lawn level. Is this a good idea? Is this the right time of year to do it?
