All the time since day dot. They are 20 and 14 now. Still out there all the time. It has been great for paddling pools etc over the years, even this year we have had a blow up spa thing ( my eldest bought it himself ) and they are never out if it. Handy when they had their friends over and still now. All the mess stays outside and when they were younger they used to love being in the paddling pool with their friends, painting , making these annoying loom band things that kill your hoover, shaping burgers for the bbq, making and applying tomato sauce for pizza's etc. Basically anything that kids love doing and can make a mess with, is so much easier outside!
During lockdown the garden provided basically all our entertainment, trampoline, spa and bbq dinners. I feel so grateful to have had the garden during this time. It allowed me and the DC's a bit of extra space and activity that we would not have had.
I also love the garden, out there most days rain or shine. Planting herbs /veg and trying to grow other bits. We grew a pumpkin one year, the kids loved checking on "him" every morning and making sure "he" was ok and survived the night! I often remember that and smile to myself. We would not have that memory without the garden. I am downsizing in a few years to be mortgage free , i will happily drop a reception room, a bedroom or two, even a downstairs loo.. and ensuite.. but a garden will always be non negotiable for me.
If i have grandchildren, i will need a garden to do it all again with them! I also love the garden. I do not think we would have faired so well during lockdown without one and the kids were able to reconnect with friends once restrictions were eased thanks to the garden. My DC's are aware now that others have not been so fortunate to have a garden and they are really starting to appreciate it now, having taken it for granted all their lives.
