Hope you have a ride on mower- Or a strong set of legs. But that grass needs attention. Get a couple of sheep to keep it cut and fertilised

Might cost a fortune in new plants but they do keep the grass down and Lamb cutlets B-B-Q well.
And periwinkle- If I had my way- it would get some immediate treartment- Couple of gallons of weedkiller should do the trick. Only having a small garden- we have about 8 different varieties that we use as Ground cover. But are always pulling handfulls of it out as it is invaisive in the borders.
Fantastic garden but Reckon you should delegate some of the jobs to the Planting Director. Either that or take in an assylum seeker that enjoys hard labour to pay for his rent. Then you might be able to get more rides in.
