As I write this, rain is being forecast for early September, following one of the driest and hottest summers on record. August has been the driest month I have gardened in, and after a dry spring and summer, the effects are clear to see. People often use 1976 as a comparison, and its longevity was extraordinary, although we have had considerably hotter individual summer months in recent years. Rainfall between March and August is almost identical to that of 1976 (to 27th August). However, it is the night-time temperatures which stand out, being considerably higher than in 1976 and bumping up the averages.
What has been a real surprise this summer is observing all the plants that have thrived without rainfall. We give plants the best possible start with good soil, compost and water, but after the first year they must look after themselves. We have watered a few areas of the Palace with sprinklers twice this year, for an average of two hours in each area, just enough to keep some plants fresh. Plants that have thrived include the Bishop’s Dahlias, Geranium ‘Rozanne’, Sedums, Artemisias, and roses such as ‘Sally Holmes’, along with grasses like Stipa tenuissima. Our exotic border of Japanese Banana, Canna, Agapanthus and Phormiums has also done well. Other drought-proof exotics include Eucomis (pineapple lily), Hedychium (ginger lilies) and the Fatshedera (tree ivy). If you wish to see many reliable drought-proof plants and some exciting September colour, then a trip to the gardens will be well worth it.
The Garden Team look forward to welcoming you in September. If you have any questions, please don’t hesitate to ask.
